My 32 doesn't have a clam sh*ll...just the torque tube pivot cup B-4513-A and the torque tube bell. Is the cork not used? Thanks!

If I understand what you have written and that your transmission and rear axle assembly are of the original type, the absence of a B-4520 outer cap suggests that your rear axle assembly is effectively unattached to the back of your transmission. That would be undesirable bordering on the dangerous. '32, '33, and many '34 torque tubes were manufactured with a one-piece B4520 incorporated on to the torque tube. As a running change in '34 production, the cap was made in two pieces, making it much easier to work with, especially when it came to installing the cork or felt strip in the back of the cap. (I much prefer the felt seal as it is more flexible than cork and not prone to breakage.) You will need to find a two-piece version of B-4520 to complete the attachment of the torque tube to the back of the transmission.

I didn't describe the situation properly. The car is original and has the B-4513 inner bell with 2 holes 180 degrees apart in the bell surface (I'm guessing to lubricate the universal joint). That inner bell has a 4 bolt flange that matches the 4520 (1 piece outer bell with 1 grease fitting) 4 bolt flange. Both are installed on the 4 T bolts on the B-7085 bearing retainer. Does the cork strip fit into the back of the B-4520 1 piece outer bell that can only be accessed after removing the speedometer gear and sliding the outer bell back on the torque tube? Also, I'm not sure it would clear the mechanical brake linkage. As the two bells seem to currently fit together well and I haven't had any leakage, is the cork gasket a solution looking for a problem? Thanks. I looked at 4-21 of volume 1 and couldn't determine the cork location.

Thanks for the additional information. Now we are on the same page. The absence of leakage from the back of B-4250 suggests one of two things. Whatever seal is inserted into the formed channel on the inside of the back of B-4250 is still in good shape and doing its intended job or your universal joint is starved for lubrlication and there's no grease left for it to leak out the back of B-4250. If you suspect the latter, lube the U-joint and check it in a couple of days for leakage. If it were a fresh installation I would recommend John Deere cornhead grease as it remains semi-solid unless in the presence of movement and therefore less prone to leakage in this and steering gear box applications. However, I would check with a John Deere dealer as to the compatibility of that product with other traditional greases. If you conclude that you should replace the cork or felt seal in the perimeter of the rear of B-4250, yes, you will have to remove the speedometer gear housing. If you rotate B-4250 ninety degrees, it should clear the top of the brake cross shaft. Replacing that cork or felt seal in B-4250 is one of my very least favorite tasks on a '32-'34. Patience and perseverance are the orders of the day.

The inner cup was full of grease, so I intend let sleeping dogs lie. God Bless felt seals! Thanks for the reply...
