Re: Found another Chevy
I stayed after work a couple nights and managed to cobble enough things together to take the old '45 out for a short ride today. One of the hurdles I had to jump thru was getting the T case cleaned out and getting the shifter rods freed up and functioning. The gear oil that came out of the drain plug was really old and thick so I thought it would be a good idea to rinse the whole thing out.
I did this by installing the jack shaft and filling the T case with diesel fuel and then running the engine for a few minutes in different gears. I repeated this 3 times and called it good enough. I also put floor jacks under the left side to improve drainage. For whatever reason the diesel fuel didn't really leak by the oil seals but the gear oil sure does, this thing leaks like a screen door on a submarine. Along with the first drive came the first accident, having only a parking brake wasn't enough to stop me from crashing into the firewood rack. The damage was minimal, only bent the bumper.

Re: Found another Chevy
That's just too cool Jon! First drives are the most fun even with a little crash...you are the right man to fix that kind of metal issue.
I was told that that crashing into soft targets was they way they stopped my 42 truck before she was finally put out to pasture.

Re: Found another Chevy
Thanks Paul,
Taking the first ride became an obsession as soon as I got the sheet metal on, there's lots of things to revisit (like the bumper and leaky transfer case) but well worth it.
Hi Kirk,
The cowl seems like it should have had some kind of doubler under it, kind of like the windshield hinges. Best to do somethings before paint.
I guess smashing into the wood rack sorta proves I'm a bit of a "Leadfoot" Huh Dave? Coming out the back door of the shop is a little tight, i guess i was going a little too fast . BTW those tires are "Mile Mark" 8.25x20's. I bought them used on Craigslist, they are in great shape except for some cracking on the side walls, i wish i had a couple more. Another issue that I had to deal with was not being able to get enough adjustment out of the clutch. I ended up shimming out the pivot ball on the inside of the bell housing and it made a world of difference. Has anyone else had problems with this? I removed the 7/16'' internal tooth washer and replaced it with a 7/16'' flat and lock washer.

Re: Found another Chevy
Last but not least I had a hell of a time getting the drivers door to open from the inside of the cab. I took the inside panel off and found little critters had made a home.
Does anyone have a source for a new door handle and related hardware?

Re: Found another Chevy
Your fork maybe worn out. I think I recall on mine it was worn thin where it slides into the throw out bearing. Throwing the geometry off at the pivot ball. Your washer pitched the fork back . Gave you some more adjustment. Just a guess. It was years ago I was into mine. The ball could be worn screwing things up.

Re: Found another Chevy
Thanks Cooler King,
I think all the moving parts are worn creating an accumulation of tolerances. Non of them looked excessively worn, I guess it all adds up.

Jon, click this link. It will take you right to the section Phil was talking about. I have found some really great parts in this section. Dave.

Re: Found another Chevy
Jon,
You are on the mark with the accumulation of wear. The most pronounced items are flywheels and pressure plates that are surfaced too many times. A few thousands here and a few thousands there are greatly magnified at the fork adjuster. The washer is a good method to accommodate for the "shorter" stack of clutch related parts. Easier to remedy items are the fork and adjuster hook, look for obvious wear and you can build them back by adding metal. If the socket part of the fork is worn out, junk it and find an NOS one, they show up.

Re: Found another Chevy
Hi Guys,
Put the doors aside for a while, they are more of a mess than i originally thought.
I have read the transfer case section of several TM's to the point where I almost have them memorized. Here's a stand I made to support the case during the process. The case that's in the pic came out of my '42 and has a damaged case, most of the internals are in really good shape. As a practice run I dis assembled and re assembled this case to see how it went, the books really do a great job of guiding you thru the process. Here it is all stripped out... The good book references a Kent Moore puller, I didn't even bother looking, I made my own. Found a bad bearing inside... The "Good" transfer case i took apart has a couple of badly chipped gears, I think I'm going to end up with a salad transfer case.
Here's the axle flange nuts from the "Good" case..., Is it really that hard to find a 1-1/2'' socket? More to come...

I like the frame and puller you built. Very impressive.

I continue to be amazed by your shop-craft. You are truly a metal working artist!

Re: Found another Chevy
Thanks Guys,
The stand and puller really helped me out, I've managed to go thru and re install 2 cases. I replaced a few bearings and combined the best parts of 3 cases to make 2, it seemed to go well. The case that came out of my '45 had these locking plates over the bolts that i have not seen before. The bolts were all super tight, 3 or 4 of them broke. The bolts have been in there for a long time, the shanks were wearing out from supporting the weight of the case. Here it is getting ready to go back under the truck. I used a 1'' ratchet strap to secure the case to the floor jack. I added a street elbow to the filler hole to increase the oil capacity a little.

Re: Found another Chevy
Jon,
What year truck did the top plate on the right side come from? Looks like the diagonal relief sections helped with oil distribution in some way, none of the 1941-42 cases I have removed had that design.
The t-case bolt lock plates were originally on all of the trucks. Where did you source the replacement bolts with the holes?
Looks like you are in the T-case rebuilding business, and making good progress.
