I scored a transmission the other day. I inspected it and everything seems to check good -,looks like a take off from a running machine. The only thing that looks odd is the large main shaft ball bearing in the trapdoor isn’t shielded on the outboard side. Seems fine - just not shielded. The assembly looks to have been together and run for a long time. Is this good to go, or should I put a shielded one in?
