Finally I think spring is here, we had a very warm winter mid 50's in December, but January got got, and almost like clock work it rains every weekend, but I have made some progress, I sanded down and primed the interior, taped off the dash and got a couple coats of paint in, this afternoons made three coats, a couple more on floors and door openings, now if the weather holds I plan on pulling the bed out of the back 40 and get started cleaning it up, I need to rebuild the tool box in the back but the floor, which is wood, looks good enough to use, I still haven't installed the decals for the engine yet, I'm going to wait till it stops freezing at night just in case!

Looking good, Bob. Can't wait to see more photos.

I probably should start thinking about putting the front end on, but it's just so much easier to work on without those big old fenders getting in the way, we have another storm coming in this week end but then we should back to spring!

Bob,

Found the site showing a 1 1/2 ton GMC. You may not be far off with your project.

One problem I have been fighting is trying to restore the data plates, they are the thing zinc plates with very shallow printing, on my half-track I did they were brass with deep printing so it was quite easy to paint then the lightly sand off the paint from the high spots, but these zinc ones are so thing and not very flat so when you try to sand off the high spots, lettering and border, you end up sanding the background as well, any one found a better way to get the plates looking good again?

I think spring may actually be here now, since it snowed all day last Saturday and today is 75, I've spent the last month doing projects around the house and fighting the weather, but today I got back on the truck, I've been pondering the brake problem and figure I should see just how much brake I would get with just the master cylinder, my booster was trash so I removed it when I modified the frame, I had plans for sticking a newer vacuum booster and master cylinder under the floor, but I was curious to see what I could get, so I loosened all the bleeder valves, which meant grinding a 3/8 box end wrench down to almost nothing to get on the front one, I have pressure bleeder so I hooked that up, I tried to do a standard bleed start at the back and work around, I wasn't getting anything, so I removed all the bleeders and stomped on the pedal, finally that got some results, very nasty crap came out, I let the fluid drain till it cleared up then installed all the bleeders valves then went around and bled them one more time, finally I had some pedal, so I got the truck running, filled the cooling system and took off around the yard, once I got some speed up I stomped hard on the pedal, nothing, I had pedal but it did nothing to slow the truck down, this truck has been sitting for over 20 years so I know I will need to rebuild the wheel and master cylinders but I thought I would get some kind of braking, this isn't the first vehicle I've resurrected and I've always have gotten a little bit of brakes, even my half track got enough brake to stop it and I didn't bother rebuilding anything on it just bleeding got me pedal, I'll have to lift the tires off the ground and see if it's all the wheels not doing anything or just a couple, could be wet linings too, at least I'm finally getting back to it.

I started with the wheel that was leaking the worst, left rear, the spring was broke and the shoes were worn down to the rivets, I had a spare set from one of the CCKW's which looked like new rebuilts, I pulled my extra chevy axle out and pulled it apart, the drum was nice and clean and the bearings looked good, the axle was broken, but this came out of the truck with the blown tranny and clutch, someone really beat this poor truck, when I pulled the drum off my truck it never dawned on me that the bolts holding the axle in were 1/2, till I tried to put them back in, after checking the rest of the CCKW and chevy axles I decided some one must have stripped the threads out at some point and opened these, but I wasn't too worried because I had a nice clean drum to use, till I tried to run bolts into it, I even blew them out but the threads are still messed up, I ran a drill down them,just a little smaller then the thread and blew them out, I tried to run a bolt in a with the impact and it broke! At the point I decided to call it quits for the night, maybe I'll have better luck tomorrow!

Bolts for rear Banjo Axle Flanges on Chev 4X4 and CCKW are 7/16" X 1-3/8" NC and OEM have a special shoulder. They must be installed using OEM Terneplate Gaskets, use of paper or Silicone will allow them to slip and enlarge the bolt threads in the hub. This has been a problem forever with trucks repaired without using the proper rear axle gaskets.

Brake update! The drivers side finally got put back together last week, I had to run a tap down each bolt hole because the drum had been sitting with out bolts in it, BUT the bearings looked great, they broke the end of the axle some how and pulled it out but stuck the broken axle back in the hole, so I stole bolts and a gasket from a parts axle and got it all back together, then I pulled the passenger side off, the shoes were to the rivets, but the drum still looks pretty good, no oil or brake fluid in this side, so back out to the parts pile for a good set of shoes, the wheel cylinder on this drum was froze up tight so I pulled one from one of the other axles, it cleaned up OK but not great, so I used a brass punch and knocked the original cylinder apart and honed it out and it looks much better, I picked out the best spring and lubed the new cups with clean brake fluid and put it all back together, by this point my back was done for the day so I covered every thing and called it a night, tomorrow I'll get the drum stuck on and try to get one of the fronts apart, maybe by the end of the month I can get this thing on the road!

[bobc]

When I got the front wheel off this morning I thought I would cheat and just remove the drum and leave the hub alone, so far all the bearing have been perfect, but when I finally got the drum off it was nasty inside, every thing was covered with an inch thick coating of slimy black gunk, so I drug a outer axle assembly over and tore it down, it looked new inside, so I pulled the whole backing plate off and just used all the interior parts, rebuilt the wheel cylinder,packed the bearings, and got a fresh coat of paint on it,3 down 1 to go!

Looking great! one of my favorite projects in progess I follow on this site. It's sure got to be nice to have the supply of spare parts on hand that you do. I look forward to seeing more as the truck comes together.

That slime and gunk was likely the result of worn out outer axle seals that are just behind the CV Joint at the outer end of the axle tube. If they are worn, it will happen again.

[bobc]

Thanks, I didn't have time to dig into the manual to figure out where the seal was to keep the oil in the diff, I figured there had to be one some place, the knuckle was about halfway full, when I pulled the backing plate off oil came out of the bottom four bolts, it had plenty of time to drain while I was changing out the backing plate. Do you have that seal in stock? It would be for a 45 CCKW banjo axle!
