Door A Explodah

Mar 15 201911-57 AM - Copy

I dunno why, I glanced at the hinge area of the door. There was some flaky loose bubbly paint there… Gee. Picked at it with my finger and the paint came away pretty easily – in big chunks? Got a screwdriver and scratched it a bit… and it went through the metal. Made a sort of sickly scrunch sound. Like putting a screwdriver into some gravel? Awww… I’ll take the door off and have a look?

Door off, onto sawhorses in the driveway. Scratch a bit more with screwdriver… oh man. I’m going to be sick. Paper bag time. Breathe… gee. I’m going to need a new door. Wondering if I can find a matching color I find some used for $100-$150 but then the shipping is $250+. $400 for a new door? Hmm. For $400, at my beginner welder hourly rate of $0.25/hour, that’s 1600 hours of welding. I could probably build a whole new truck out of mig blobs in 1600 hours. I put the door back in the truck. I gotta think about this…

Next day I have another look. Gee. This doesn’t look SO bad. Its just metal. I can grind the bad stuff away and replace. Pretty clear though that the POR-15 from previous owner did nothing but hide the problem for a few years… can’t hide from the screwdriver of truth though…

Mar 15 201911-57 AM_1 - CopyMar 15 201911-58 AM

I take the door back off, get out the grinder. And the mask. And the face shield. Pretty much complete welding attire to protect from the brown cloud that’s about the envelope the area.

Mar 15 201912-28 PM

Most of the outer skin is just gone after grinding. Some of the second layer is gone too. But there’s a ton of good metal around. This is no big deal? I’m generous with the grinder to get to nice thick metal. I am a bit concerned that what I rebuild needs to fit like the old door. The area I need to be most careful about is where the rubber seal hangs on the door. Need to follow the original lines. Otherwise the door won’t door.

Tin snips and jigsaw, I cut out metal, hammer and bend, freehand repair pieces, then glue them into place with my mig.

Mar 16 20193-04 PMMar 16 20193-20 PM

Having nobody to show me how this is done I get to experiment with a bunch of different techniques. The metal is nice and thick and the rust is gone I have no trouble with burn through. Lovely to have a big chunk of metal as a heat sink. The inner layer is soon filled. The other trick is lots of small blobs of metal. Zap-zap-zap. Pointillist style. Like Seurat? Gotta be careful though because its easy to have holes between the points. So sometimes after I’ve got the surface where I want it I’ll draw a bead across, melt it all a bit, then grind it back with grinder.

After I’m satisfied with inner layer I spray it all with zinc primer, then start on the outer layer. I’ve got 16g metal so that’s what I use. Even though the door is thick metal, the 16g is much thicker. I cut pieces to rougly the right shape, then grind down until they fit like my eye says they should. Weld one edge into place, then hammer the piece until another edge is in place. Eventually the piece is welded flush. Pretty neat!

Mar 16 20194-56 PMMar 16 20195-59 PMMar 16 20195-59 PM_1Mar 16 20196-00 PM

End of the day I hose it all down with zinc primer. Tomorrow I’ll be done!

Mar 16 20196-19 PMMar 17 20199-41 AMMar 17 201910-47 AMMar 17 201910-47 AM_1Mar 17 201910-48 AMMar 17 201911-20 AMMar 17 201911-31 AM

This was a pretty interesting process, build up with mig, then grind down. In one section I had too many pin holes, I needed more heat. So finally I cranked slowly across the whole area real slow, drew a huge fat bead. That did the trick.

What this process taught me is that no matter what, I can just grind all this muck away in the future and do it again. If there’s corrosion, if it starts to come apart, etc, if it looks at me funny… I can grind it away and do it again. I’m empowered!

Mar 17 201912-50 PM

Last little bit went real slow. I used a bright light to see any pits or holes, fill them with weld blob, then grind down. Weld it all, grind it all, find more pits, repeat. But finally it was good enough. Hosed it all down with vht suspension paint:

Mar 17 201912-56 PM

This maybe took me 10 hours of work? I reinstalled the door. It is lovely to see, smooth to the touch. The black paint isn’t really notable.

Most frustrating thing though… this is the best most complex work I’ve done and its pretty much invisible to anyone. I gotta open the door and point them into the hinge area and even then it isn’t really clear how much new metal is there.

Anyway. Now the driver’s door is looking at me funny. Looks like a lesser version of the same issue. Wonder how much easier it will go with my new skillz?

Bubbling Paint on the A Pillar (and other assorted rust bubbles)

For a while I’ve been casting sidelong glances at the top of my a pillar. Paint there is sort of bubbling. A bit.

Try not to think about it because its so horrible. What if whole a-pillar is just a giant bar of rust? Is that a fatal problem?

Today I got out the step ladder and went at that rust bubble with a screwdriver.

I didn’t take a picture before I started but it was just blue paint that had bubbled a bit. But it was also a bit soft to the fingers. So it was paint over something that wasn’t solid.

I scratched the paint off with a flathead screwdriver, then kept scratching at all the softness, the bubbling brown rust, until I’d explored the limits of the badness.

Unfortunately the rust extended to under the windshield seal, which means I can’t fix it with the mig unless I remove the windshield.

Here is right after I started to scratch:

Mar 09 201912-26 PM_5

After I’d scratched and ground it clean, then painted with ZeroRust.

Mar 11 201912-09 PM

I drove the car to my local awsome glass shop. They said… um… this isn’t exactly a… ‘rotisserie restoration’… the windshield will probably break if we remove it… prolly you should put in a temp fix and do the welding when the windshield needs replacement.

Just as I got home my wife got home from her moms, she handed me a half used pack of JBWeld Steel Stick. Age Unknown…

So I tore off a chunk, worked it for a minute and then jammed it in the rust hole, pressed it way up into the hole using a screwdriver. Kept pushing until it was jammed hard with whatever epoxy that is. My goal was to press out any voids.

When I was done it looked like an old hornets nest.

Then nearby were some other small bubbles in the paint… sure enough these were hidden rust holes. I gave it the same treatment except I could grind all the metal clean with my angle grinder, cleaned the underneath as well as I could, then hosed it down with some coats of zinc paint. And then I repeated that work on 2 other rust holes.

After a few hours the zinc was dry enough to weld. Because there was no seal nearby I filled the holes with zaps from the mig welder. Then grind the welds down. Pretty nice.

The main thing is to give it two small zaps, then wait until the metal is warm to the touch. Generally a minute between zaps. This keeps the heat way down, avoids warping the metal or catching the car on fyre.

Mar 11 20193-28 PM

Just starting to weld up a larger hole. Lots of time to take pictures while waiting for the metal to cool…

Mar 11 20193-28 PM_1

Right before I close up the welds with the final blobs I give the hole a generous blast of zinc paint. Maybe help to seal up the backside of the new metal.

Mar 11 20194-13 PM

Finally grind the welds down most of the way, then paint with VHT Epoxy Suspension Paint. To cover the welds I used 4 very light coats with 10 minutes between. The jbweld was thirsty though, it took 3 heavy coats, just kept sucking up the paint, which I think is fine.

Mar 11 20194-23 PM

Started raining last night.

I am wondering how to help reseal that windshield rubber until that distant day when the windshield comes out. Supposed to use urethane glue to hold rubber onto the metal and glass…

Tail Repair, Tailgate

Leaning into the back of the truck I put some pressure on the tailgate and noticed it creaking. Bounced it a bit with my weight and the entire bottom seam was flexing. The entire bottom seam was rusted out.

That cannot stand!

Mar 04 201910-42 AM

First I ground away all the bad metal. And the sealant. And then it was really true that there was no bottom seam at all.

I welded in a bunch of tiny scrap pieces. Went well, took a few hours.

Then noticed nasty stuff on the outside. Oh well, might as well fix it.

Mar 07 20191-32 PMMar 07 20191-32 PM_1

Mar 07 20191-31 PM

Finally back on the truck with mismatched paint:

Mar 07 20194-42 PM

Whhaaaa! A Hefty Pair of those Nasty Rocker Panel Ends

Can’t fit THAT on the album cover.

I was going to ignore the rocker perforation but wife had an opinion this once… “Well… You can’t leave it like that.”

Uh… honey? I’m tired? I feel like I’m getting done with this welding stuff. This manual labor is starting to make me hurt.

Ok, well we’ll see I guess.

I started on the passenger side at about 2pm after welding all morning. And somehow everything went right. Got it done in about 2.5 hours. Pretty fast I think.

Yeah, in hindsite this does look aweful. But no water into the cabin. How bad can that be?

Ground away all the bad metal and realized there was enough good metal that I could do this bottom part with a single piece. I went with the tried and true “weld some of it in, then hammer and grind it to fit” technique. And that worked great just this once.

Feb 28 20192-55 PMFeb 28 20192-59 PMFeb 28 20193-12 PMFeb 28 20194-47 PM

I was pretty happy with how quickly that came together. So the next day I plan to zap the driver’s side, which has slightly worse rust:

Feb 28 201912-15 PM_2Feb 28 201912-15 PM_3

Well it turned out there were some significant differences. Enough metal had gone by-by that I had to make multiple complex pieces. And that took a lot of time. The upper bit went well but it was a u-shaped piece that needed to curve in 2 dimensions. I fit the piece and then cut darts out of it so it could bend. This took 3 hours.

Feb 28 20194-47 PM_1

Then ground away the bad metal in the rocker. The backside and inside of the rocker are rusted and need to be cut away and replaced with new metal.

Feb 28 20194-47 PM_2

Here I had to make a pretty complex piece with a cereal box.

Mar 01 201910-31 AMMar 01 201910-31 AM_1

I mean look at that thing… and then folded, welded, folded again, welded more. Complicated. And this is just the end of the rocker tube.

Mar 01 201910-31 AM_2

Trace the piece on the sheet, then cut it out with jigsaw. Thank goodness I have that bosch jigsaw, best tool ever. Cuts like a damn laser.

Mar 01 201910-34 AM

Was tough going to weld that piece in. Not a lot of room for the torch. Welded the seam on the outside, then welded it on the inside.

Mar 01 201911-33 AM

Then I zapped the inside of the rocker as much as possible with zinc paint.

Mar 01 201911-34 AM

Then fold the panel shut and weld that seam. See what a complex shape that is! I’m impressed.

Mar 01 201911-56 AM

Then make the outer wheelwell lining.

Mar 01 201912-10 PM

Weld into place with darts, then hammer the tabs over and weld the seams.

Mar 01 201912-50 PM

Then grinding:

Mar 01 20191-00 PMMar 01 20191-00 PM_1

Yes, insanely strong.

This one side ended up taking all day.

 

A Yucky Little Hole Is Fixed

One of the land cruiser logo stud holes had rusted through an perforated all around. About a 2.5×2.5″ section.

This went really easy.

Im getting lots better about controlling the heat. Pretty much only do short tacks now. Let the weld cool before I put down another one.

Feb 27 20191-54 PMFeb 27 20192-09 PMFeb 27 20192-11 PMFeb 27 20192-14 PMFeb 27 20192-22 PMFeb 27 20192-27 PMFeb 27 20192-28 PMFeb 27 20192-38 PMFeb 27 20192-47 PMFeb 27 20192-56 PMFeb 28 201912-15 PMFeb 28 201912-15 PM_1

I even checked from the back in bright sun and no pinholes. I chalk this up to my using more heat and hitting the metal in shorter bursts. Got better penetration, no pinholes. Awesome!

Lots More Welder-ing On That Truck

Have been really busy fixing rust.

First was the passenger side rear quarter panel. Its just that little bit of rust above the mud flap?

Feb 20 201911-42 AM

Well, I cut in a bit large in case I found anything interesting.

Feb 20 20192-51 PM

Yeah… that’s not good. I need to see better, get better access…

Feb 20 20193-22 PM

That is the wire that tells the car that the rear passenger door is open. It goes through a big giant piece of something yummy. Some rust stuff? Filler? JBWeld? I have no idea. I pryed it loose with a screwdriver and found the underside was in really great shape! But the wire was solidly embedded into it. I cut the wire and spliced in a new one.

Then got to work grinding away and replacing bad metal.

This job went much easier than the driver’s side because the quarter panel still had its base and back side. It was good to cut away a big area for access and I was able to weld the piece back in when I was done.

Again the 16g sheet makes for some really strong wheel well arches. I left the bad metal in place to use as a form, cut it away once it was time to weld in its replacement.

Feb 21 201911-47 AMFeb 21 20191-15 PM

Feb 21 20191-47 PM

The final piece of wheel arch here was sort of tricky. Had to do some Vice Origami(tm). Was surprisingly difficult to get a piece curved in 2 directions and with funny angled sides. And I screwed it up a little.

Feb 23 201910-22 AMFeb 23 201910-27 AMFeb 23 201910-28 AMFeb 23 201910-32 AMFeb 23 201910-34 AMFeb 23 201911-18 AMFeb 23 201911-18 AM_1

Feb 23 201911-25 AM

See once its welded in there is a triangle gap. Darn!

That is the last time I’m freehanding a complex metal piece. Cereal box template from now on!

Feb 23 201911-25 AM_1

So I fill that triangle with a piece I had laying around:

Feb 23 201911-35 AMFeb 23 201911-36 AMFeb 23 201911-37 AM

Once its all snug and welded in place I grind the extra away. Simple!

Feb 23 201911-45 AMFeb 23 201911-45 AM_1

That double-curved boxed section is incredibly solid. Like wow.

Then weld in a new piece and get to grinding.

Feb 23 20191-23 PMFeb 23 20191-23 PM_1Feb 23 20191-29 PMFeb 23 20193-41 PMFeb 23 20193-42 PM

And finally… I hit it with filler. Ouch!

Feb 27 20191-54 PM_1

Nope, this isn’t a pro job, that’s for sure.

But it is strong!

 

 

Finally a welded patch done mostly well

I talked to the maker of my MIG, they pointed me to a place in north Carolina that sells parts for it. Got a new wire sleeve and a new nozzle for $17. Sweet!

That’s good news. The better news is that the old nozzle was about 1cm too short, so wasn’t getting good gas coverage of the weld. AND the wire sleeve was sticking, it was just a plastic straw, this new one has a coiled wire housing, much stiffer and should work better.

And the best news is that both these things have massively improved my ability to weld. Live and learn.

So today I took issue with the second patch that I’d made:

Jan 15 20194-36 PM

Since it wasn’t raining or snowing I made a move on it. Ground it away and found the rust soup I expected. So I got out the ‘ol grinder and cut out all the old metal. And then cut it in a nice rectangle so it’d be easy to make a piece.

Feb 19 201911-24 AM

Then I cut out a conservatively larger piece of 16g and then sat by the hole and ground it down until it fit.

Feb 19 201911-24 AM_1Feb 19 201911-24 AM_2

Here I screwed up. Believe it or not the metal you add with the mig wants to go in the groove between the metal. So when I mig’d this tight fiting piece along the bottom it pressed up against the top and so then it dint’ fit any mores.

Feb 19 201911-25 AMFeb 19 201911-27 AMFeb 19 201911-27 AM_1Feb 19 201911-41 AMFeb 19 201911-46 AM

You can see now that there’s a diagonal bend in the panel from the patch to the upper right… Meh.

Something else I noticed, this was good metal to good metal and the tack welds were so solid. And it was really easy to fill the whole thing. When I was done with grinding there was just a single hole to redo. Much better than welding to bad/thin metal where attempting to fix a hole means blowthrough and more hole.

Here is after the first grind. The gap is mostly solid metal. Success.

Feb 19 201911-49 AM

Welded the holes and ground again. Solid!

Feb 19 201912-03 PM_1

Then hit it all with primer and it started to rain.

Feb 19 201912-03 PMFeb 19 201912-04 PMFeb 19 201912-10 PM_1

Wish the weather was better. Anyway. Planning to paint it soon… Gotta wait for a warm day I think. Right now its raining and sleeting.

 

 

Redeeming A Previous Welding Crime

Got sick of looking at this horrific patch I applied when I first started welding on the truck. I literally cut out a square of 24g and slapped it over a rust hole, then welded the edges. It just never stopped looking grotty. And after a month I figured it warn’t going to get better on its own…

Jan 19 20192-53 PM_1.jpg

Square patch in the upper right… its gotta go!

So… I got out the grinder and took out the welds. And found a soup of rust and misery just hiding back there to terrify me.

Feb 08 201911-07 AM

I don’t know what I expected to happen. I guess this was just a total lack of clear thinking. The black stuff is dynamat.

So then its clear that problem is worse than I thought, that I need to just disappear a bunch of bad metal.

Put on the cutting disk and take it away.

Feb 08 201911-22 AM_1Feb 08 201911-22 AM

The thing is, there’s no point being precious about a little rust hole. Its just a huge waste of time to try and save it. Cut it all away and put in good metal. Much much easier and will be durable.

The trick is to get the new piece to fit nicely. Here I made a boo-boo and didn’t trace a nice square rectangle, I got sloppy with the angle grinder and cut out a trapezoid. So then I put on a grinding disc and made it back into a rectangle, or at least something with straight edges.

Then I cut out some 16g with the jig saw and ground it and the hole until they agreed about the shape.

Then magnets to hold the piece into place.

Interesting thing, tack the bottom edge where its flush. Then hammer the rest of the edges until they’re flush too. Just slowly coerce the thing to be flush. Once a point is flush then tack it.

Feb 08 201912-00 PMFeb 08 201912-00 PM_1

Feb 08 201912-00 PM_2

This doesn’t look great but its fine. I tack the bottom edge where its flush, then the top edge can be pushed into place. No big deal.

Once the first tacks are done the magnets go away, just tack around the new metal.

Then I grind the tacks smooth, and finally I weld the seam, a butt weld. Weld about an inch at a time and let it cool. Once I’ve got a whole lap done I grind it all down.

Because I’m a terrible welder there are 10 places with holes in my welds. I weld these holes up, then grind them down to find one more hole.

Feb 08 201912-11 PMFeb 08 201912-11 PM_1Feb 08 201912-28 PMFeb 08 201912-29 PM

Unfortunately its now snowing hard so I need to stop. I hit it all with metal etch primer and put everything away until later.

Feb 08 201912-47 PM

Because I used 16g the new metal is really damn strong. Looks good inside and out. Next sunny day I’ll grind the welds down smooth and paint again. This is much better and more permanent than the old patch technique. And now I’m not afraid of cutting metal away. I’m glad this was a nice flat section.

Cheers!

Replacing the 3B Fuel Air Diaphragm

On returning to seattle I found and ordered a new leather diaphragm for my motor. $50 mailed from California, I got the denso part instead of one made by Toyota. The theory is that the cause of my high idle is a deteriorated leather diaphragm is leaking air and causing the injector to provide too much fuel to the motor.

Part arrived in a nice little cardboard denso box, inside is a plastic bag containing the new diaphragm. The box is made from nice Japanese cardboard – you don’t see much paper like that here in the states.

Denso Box, new diaphragm in bag, and old diaphragm right after I took it out of the truck.

Denso Box, new diaphragm in bag, and old diaphragm right after I took it out of the truck.

As box had a digital signature sticker – could this thing have been made recently? Is it possible that somewhere in Japan there is a workshop still making these? Someone packages up leather and sends it to denso where it is cut and made into fuel diaphragms?

I read up on the replacement procedure on the internet, have the assembly well-visualized as its apparently impossible to see well without removing the engine. Some folks say the diaphragm is difficult to remove even with the engine out. I’ll be leaning over the side with a headlamp on… huge sausage fingers. This won’t be fun.

There is lots of complaining on the internets. Lots of cases of dropped  washers and nuts. Since the car won’t be drivable once I begin the procedure, I’d like to be sure I have everything I need before I start. The three recommendations that stuck with me:

1) Have a stool to stand on, I’ll have my head crammed against the base of the hood.

2) Have some needle nose with an angle tip.

3) Have a magnetic wand to retrieve anything I drop.

4) The tiny bolt inside is 8mm. Need a tiny 8mm wrench.

I go to 5 different stores for angle needle nose before relenting an buying a variety 6 pack at Harbor Freight. For $6. I am willing to pay more but you need to have it in stock! I also picked up a locking forceps at harbor freight for $2, in case I decide to try removing by pulling the pin.

Arrive back home for the big job. Clock starts at 1:30pm.

First I need to undo the housing. Appears to be 2 flathead bolts holding it on. The top drivers side flathead is threaded with mechanics wire which I snip.

I am able to undo the first using a tiny ratchet, takes 3 minutes. The second is a bitch, I’m on my stomach hands dug way in there undoing the flathead one click at a time. 5 minutes. And then I see that there’s another bolt underneath. Dang. Three bolts!

There is an arm that comes off the edic that is really where I need to have my hand. The near side of this arm is an easily removable press fit onto a knob. Just pull up and its free, tuck it out of the way.

Undo the 3rd bolt, again its tough, takes 10 minutes.

And then I see that the housing, while very loose, is being held by another flathead bolt that I can’t see. Dang, the thing is a square and there are 4 bolts. Feeling with fingers in the grime I can determine the direction the flathead is turned, line up the socket and slowly click away. Interesting that this flathead was pretty loose before I started. Maybe that is the actual problem? Maybe I just need to tighten it down and all is good? Make a solid seal? I’m too determined, I’ll get the diaphragm out and see. I can’t believe the diaphragm removal can be worse than these f’ing flathead bolts.

3b fuel diaphragm

View of 3b fuel diaphragm in place with housing removed. Can see the tab at the base of the diaphragm slots into the injector.

It could be my difficulty is due to having the wrong tools. I have a screwdriver that will fit but there just isn’t room to grip and apply torque. I go with a small ratchet, an extension and a flathead tip but there’s just no place to turn it. Maybe there is a cable-tip screwdriver that would work but not clear how to hold the tip onto the screw. Flathead is just such a bad choice for something like this. In hindsight I should have replaced them with allen head bolts where the head grips the tool.

Finally get the last flathead out and housing is free. There is a spring that pushes the housing out which I remove and set in my tray with the flathead bolts. There is a hose coming from the top of the now-loose assembly that I hang the assembly from.

The diaphragm is picked out with my fingers, it comes out about 1.5″ before being restrained by the internal attachment. Pulling out with full extension of the leather I can peek inside if one eye is in exactly the right place: there is a brassy cotter pin on the drivers side. On the other side I can feel the 8mm nut. I’ve heard that the pin can be pulled so I try that first with some locking forecepts. I managed to take a few photos with my cell phone, very very hard to get a clear shot though.

3b fuel diaphragm

View behind fuel diaphragm, there’s barely room to fit my thumb in there. On the left you can see the head of the cotter pin (that was manged, that I couldn’t remove.) On the right you can’t quite see the 8mm nut that must be undone…

3b fuel diaphragm

Another view behind 3b fuel diaphragm. Cotter pin head visible on the left, 8mm nut barely visible on the right.

After 10 minutes of fiddling with the pin I give up, the pin is mangled pretty well and too hard to untie.

The mangled pin can be seen clearly.

The mangled pin can be seen clearly.

Using the closed end of a tiny 8mm wrench I am able to undo the nut on the other side from the pin. Pretty much 10 degrees of rotation at a time. Honestly this isn’t nearly as bad as it was to remove the flathead housing bolts, just remember its a finite number of turns, take your time and breathe, stay loose. Finally the nut is loose enough to spin with my fingers. Reach in and turn with fingertips, ready to catch when its loose. I undo and manage to hold it, pull it out using fingers like a pair of chopsticks and place it in my tray. The whole time being careful not to bump the diaphram and displace the bolt which would cause the washer to fall out. Then reach back in and am able to score the washer, its like playing “Operation”. The trick is to thread thumb in behind the diaphragm and hold the end of the bolt, then reach in with first two fingers (of same hand of course) and tweezer the washer. Slowly! Score washer, place in tray and then Jangle-jangle the diaphragm assembly is free… jiggle diaphragm and out if comes. No problem, sort of jangly but nothing dropped. Time is now 2:30. I immediately reapply washer and nut so I don’t lose anything or forget how it goes together. There is an odd piece of sheetmetal that looks like it could be attached several ways, especially relative to a small tab on the diaphragm perimeter that must point DOWN on reassembly.

Old diaphragm as it came out of the truck.

Old diaphragm as it came out of the truck.

The good news is that the diaphragm is torn, has 4+ tears that are 1+mm across. Good news because likely the torn diaphragm is the cause of the high idle. I didn’t do this for no reason and probably won’t need to go to a real mechanic for some expensive diesel specific tuning.

The leather diaphragm has metal crimped around its outside and there is a tab at the bottom of the metal. This tab fits into the bottom of the injector pump. Note to self: remember to reassemble with the tab on the bottom.

Old diaphragm and attachment assembly.

Old diaphragm and attachment assembly.

I considered reinstalling with the cotter pin and I play with the assembly on my patio. I straighten the cotter pin and play with the assembly but it really looks like the cotter pin is the more difficult route to take. For cotter-pin reassembly I’d need to insert the pin, then bend it out with very little access. Just need to see I guess…

I reassemble as before (checking against picture I took before disassembling it.) I did also straighten out, unmangle and rebend the cotter pin, in case that proves to be easier for someone in the future.

Finally I brace myself for what is supposed to be most difficult part: installing the diaphragm. The diaphragm bolts to a metal rod inside the injector pump, the injector pump rod has a hole near its end, horizontal. The rod moves front to back freely. Trick is to pull the rod out as far as it will go (not very far) then gently reach the diaphragm’s bolt in and hook it through the hole in the end of the injector rod. If you bump the rod it goes back in and is impossible to hook. Takes a three tries and some crimped fingers (press the end of the diaphram’s bolt with a stray thumb to keep it from falling apart.)

Once the diaphragm bolt is through the injector rod… its time for the most demanding part of the assembly which is replacing the washer and nut.

My fingers were pretty greasy which helped the small parts stick to them. Hold the washer between first and second fingers of right hand, place thumb against near side of diaphragm bolt, apply pressure with thumb to keep bolt from moving then very very slowly… slip the washer on. If you don’t hold the diaphragm bolt in place it will back out when you attempt to place the washer.

Now… place 8mm nut between first two fingers of right hand, very very carefully press diaphragm bolt again with thumb so as not to jostle the washer, then slowly place the nut onto the diaphragm bolt, and give it a meager desparate twist with your fingers. Spin it on as much as possible! Whew! Take a break and breathe a little!

Sort of like rock climbing!

Then use fingers and finally the 8mm wrench to spin the nut on, 15 degrees at a time, good and tight… Nothing is so bad now, the job is more than half over!

Finally I grease up the metal on the edges of the diaphragm (I used Phil Wood bicycle grease) to create a good seal, then I greased the spring a little, and finally pressed the housing back onto the injector. This is again awful!

Yes indeed these flathead bolts are still by far the worst part of the process. The housing is difficult to line up. The tiny flathead bolts are difficult to thread and reach. Took me a full 45 minutes to get the 4 bolts back on and tight. Finally I rewired with mechanics wire and replaced the edic arm.

Nothing really went wrong during this whole affair. I don’t think I’d do it differently the next time but you do need to be patient. I have pretty big sausage fingers and didn’t have trouble with space. I think I might look a little more for a better sized tool to remove those flatheads. I dunno what to do about them.

Last step, I started the truck. Nice low idle, solid at 600rpm. Much more clattery, as a diesel is supposed to idle. Drove to store and idle stayed at 600-650 even though the day was hot. I guess success.

Others have noticed better power, better fuel economy, etc. I notice the truck is much slower to rev, feels more lethargic. Drives ok, maybe more torque. Maybe I’m not used to needing to push the accelerator so far? I mean it drives ok, feels more like a truck now, but I sort of miss the high revving truck I used to have. Maybe mpg will improve? If so I’ll forgive it.

Spare Tire Holder

I’ve had the spare tire holder sitting in my garage since I got the truck, just sitting in a corner gathering cob-webs with all the other spare bits I’d obtained from the previous owner. No idea where it goes, how to install. Why didn’t he install it?

Once when I had some POR15 left over I painted the rusty thing with it a glossy black, why not. Just was careful not to get it into the winder mechanism.

When I was at TorFab I hit up Tor for the install Beta and he gave me the bad news: Normally the rear frame of the truck is an open “C”, the C facing inside. My frame is custom and the “C” has been closed with a welded plate. The spare tire holder bolts to the frame, to the bottom side of the top of the “C”. Since I don’t have a “C” anymore I’ll need to find an alternative.

Now I’m preparing for the big trip I do want a spare tire but don’t want to take up a bunch of space with it, I need to get that spare tire holder installed.

Come up with a plan, I’ll bolt it on with hefty bolts!

First, cut off the ends so the span fits between the frame rails.

Angle grinder made short work of this.

Really amazing how quickly a cutting disk can do this. Metal? Sheesh!

Then bolt some angle iron onto the frame, bolt the tire holder to that?

Go to the Home Despot, buy 3/8″ angle iron, buy stainless bolts, washers and nuts.

Cut angle iron and then paint it all with VHT epoxy paint.

Next evening the paint is pretty dry, not dry enough to paint again but dry enough to go under the truck.

Order is important here.

1) Drill holes in angle iron brackets using drill press.

2) Estimate where the brackets go on the frame, mark where holes go.

3) Drill holes in frame.

4) Thread bolts from backside of frame into brackets (with washers), and tighten a bit.

5) Put spare tire holder onto brackets.

6) Drill through bracket and tire holder span

7) Attach bolts from span to bracket

8) Tighten the crap out of everything.

9) Paint it all with Fluidfilm AR, especially the winder mechanism.

A bit tricky to get the bolts through the frame from the inside, I hold the bolts with a socket. Needed to enlist my son and his little hands to help

Once everything is bolted together its VERY strong. Dang.

Putting the wheel on:

I realize I don’t know how to work the winder. There is a slot but I’m not sure what is supposed to be used to turn it, or if its even reachable with the tow hitch.

Under the drivers seat there is a post jack, behind it on the drivers side passenger footwell are a pair of clips and a rod with hook on the end. The hook fits into the spare tire mechanism, but the that piece is too short to reach out from under the car… I dig around in my spare bits and on the floor is another rod! With a  square attachment. I assume there is supposed to be a crank thing but its not to be… I use vice grips and crank the wheel up. No problem. Super secure. I’ll check the bolts after a few days.
