78 chyrsler lower unit rebuild

[ray ray]

I have a 1978 chrysler 85hp. The lower unit craped out on me the other day. I have tried to find one just to replace it but i cant. Can somebody help me out and tell me where i can get a manuel to rebuild the one i have. When i drained the oil out of it i think there was more metal in the oil then left in the housing. How do i get prop shaft out do i need a puller or what? Better yet if someone has one i can just buy that would be better thanks

Re: 78 chyrsler lower unit rebuild

That was right around the time Chrysler started to change them. Is it a one piece lower unit or two piece? One piece has a thrust washer behind the prop. Two piece has a pin in the front hub of the prop held in place by the tailcone.

One piece lowers frequently come up for sale on ebay. If the damage is as severe as you make it to be, you are better off buying a used unit than rebuilding.

Two piece are more rare and getting difficult to find. AHEM! I do have parts for them.
