Subject: [HillmanCars] Transmission Rear Seal

For Minxers: I am in the process of replacing transmission seals on my Minx IIIA and thought someone may be interested in the following:
I recently ordered the rear seal from Kip Motors and they supplied a seal mfg by Chicago Rawhide (C.R.) under part no. 13556.  However when I removed the old seal I noticed that it was a two way seal....ie stops dirt one way and oil the other.  It was also spring tensioned on the oil side.  The C.R. part is the proper inside and outside dimension but is only single sided and not spring tensioned.  I went to the C.R. local rep today and he provided the following information/solution.  This is a rare sized seal.  The better seal is p/n 13552 since it is spring tensioned, but it still only works one way.  However, the two C.R. seals together make up the same width as the old original double seal so install both with the 13222 seal towards the transmission (oil) and the 13556 towards the drive shaft (dirt). I offer this because he said the double acting seals with these odd dimensions are very hard to find.  C.R. Dealers are easy to find and their prices are a fraction of after-market dealers . . . . . . . .  but I guess everyone in the supply chain has to make a living.
Sorry for the long post.
