C10 primary chaincase

[Rick Rybicki]

Hi, Info please. I'm trying to keep as much oil inside my primary chain case as I possibly can. My 1946 C10 has the primary case back plate with the simple sliding plate with no felt washer to encourage oil to stay in the case. If I can get hold of one, could I fit the B or M back plate with the more conventional sliding plate and felt washer?
At present, oil is filling up the primary case from the crank case as there is no oil seal originally around the crank shaft. I have found an appropriately sized oil seal that fits inn the recess currently filled by the plain sleeve that fits over the crankshaft where it enters the primary chain case. I intend to reduce the length of the sleeve by the width of the oil seal and fit the combination of oil seal and shortened sleeve. Thoughts please.
Cheers, Rick.
