I found the whole intermediate bearing assembly at NAPA for my '49 3/4 ton driveshaft. Couple things I have not been able to locate:

ball collar shims
ball collar cork seal
drive shaft oil seal

Any suggestions for where I might locate these parts? NAPA did not have a listing.

The shop manual suggests that the ball cork seal be shellaced in place. Any comments on that would be appreciated.

leon,

I will post tomorrow a FelPro and/or NAPA part number for the u-joint ball/bell-housing gasket and seal set. Jim Carter & Classic Parts of America (Chevy Duty) also sell these sets.

Also, I will check the shop manual about the shellac. If shellac is used, it must be used on the collar edge, not the bevelled/curved edge that slides on the ball/bell. The ball/bell slides up and down on the bell edge of the cork gasket (as the rear end and rear springs go up and down).

Much appreciated. Are the ball collar adjusting shims the shop manual describes just gaskets?

I believe this is the NAPA ball shims & cork seal kit.

NAPA on-line u-joint housing gasket set (is not as complete a set as it used to be).

NAPA # NGA GS33066
FelPro # ES72843

The FelPro set might contain more shims (it used to contain 4 shims/gaskets; the NAPA set only contained 2 shims).

Neither set includes the drive-shaft seal (the seal between the driveshaft and the torque-tube, inside the end of the torque-tube).

Here is what I have. The left-side bolts to the trans. The shaft goes through and the bearing sits in the right-side cup. The shield slides on then the u-joint yoke bolts to the right-end of the shaft. The right-end goes into the bracket that bolts to the frame. The problem is there is a 1-inch gap between the right-end cup and the inside of the bracket. In addition I see no way of sealing this. There are no other parts.

All Parts

If you look at this bracket it looks like a piece has been welded on. Kind of hard to see. I have a driveshaft carrier bearing rubber cushion on order but I'm not sure if it fits the outside of the right-end between the outside of the bearing cup and the inside of this bracket.
Welded up

The trans side of this bolts-up fine. On the u-joint yoke end of this shaft the ring above the splines is metal. There is no seal anywhere. There are no threads on the yoke for a seal retainer ring. This whole intermediate section was wet, obviously leaking for some time.

No Seal

I'm not sure but at this point I would say this has been pieced together and there is no way to add a seal unless I use silicone or something like that. My questions. Will the driveshaft carrier bearing rubber cushion fit inside the bracket around the bearing cup and how do I seal this puppy?

Leon, try the filling station in Oregon for the parts that you need. They also have an O ring to replace the cork seal an this will help prevent leaks at the ball collar.
