No. I couldn’t rotate it before. I put in gear and used the starter to move the carrier so I could get to the bolt to remove pin.

Progress made today. Got everything but the spider gear back into the pumpkin. Ring gear was still locked so on to transmission. Pulled the top off and Neither fork was where it should be. Cleaned up the gasket flange then dry bolted the lid back down. Put in neutral and voila the ring gear turns easy as pie.

The tranny was really sludged up. Cleaned the fork slides and lubed them. I would have to guess the fluid hasn’t been changed it a while

What is a good oil to use in the transmission

Been a long time since I played with spider gears so I'll leave that to the more experienced.

Remind us again what transmission you have?

Another step closer to first drive. Got the spider gears in. It was easy once I figured out the secret. Took about 30 minutes playing with them when one feel into the gears and rotated right into place. You have to do both at the same time but once put in place they both rolled into place no problem.

WICruiser I have a four speed. Haven’t researched it yet. Pic two is the cover.

Of course I can’t find a gasket for the pumpkin cover. That and the filler hole nut came off in pieces. It had been put in place with some sort of rubber glue. But it worked I guess. So ordered a gasket and plug.

When I was a young guy working on cars we’d fill up the tranny and rear end until we could feel the oil on a finger stuck through the hole. The repair manual said fill transmission until it overflows out filler hole. Haven’t looked at rear end yet.

Oh. What is the stuff to mark the ring gear with to check and adjust the alignment called.

The 1951 Maintenance Manual called for using "red lead". Modern gear marking compound (AC Delco # 1052351) is probably easier to find at your FLAPS.


'57 GMC 102, Original 347 V8, HydraMatic, 3.08 rear gear, added A/C, disk front brakes, HEI, AFB carb, '98 Honda Black Currant paint. T-boned and totaled 10/12
'52 GMC 152 Stake Bed, Original 228, SM420, added A/C, HEI, disk front brakes, '67 Chev 3.55 rear gear. Gets used as a real truck.

What Bill said.

Although that reminds me of the time when I was back in high school and my Dad's plumbing truck (a '51 GMC) needed rear end work, and Greasy Bob, the local mechanic used the pipe dope that was in the truck to check the gear pattern. So if you happen to have some of that, it would work too.

If you're smart enough to take it apart, you darn well better be smart enough to put it back together.

As for lube in the transmission use 80w-90 gear oil.

"White lead" is lead carbonate powder in a linseed oil carrier. It's easier to see than lead oxide which is used to make "red lead". It was once used to make white paint before the tree huggers got their frilly undies in a wad about anything containing lead. Artists' supply stores sell a modern equivalent pigment that's supposedly lead free. Prussian blue is a grease based dark blue dye that machinists use to check the fit of parts with, and it hasn't been banned- - - -yet. A 2 ounce tube of Prussian Blue is probably a lifetime supply for fitting rear end gears.

"Any of the above" can be used to check tooth contact patterns. Unless a set of used gears had the tooth contact checked and photographed before they were removed from their original housing, the chances of getting a noise-free installation into a different housing are "slim" and "none".
