Hi guys, been a while since I've visited. I have a NOS 5hp from 1980 that I'm building up. It has a bushing side cover with no bolt holes and the timing gear appears to be part of the crank. What side cover, seal, and bearing do I need to convert this? I heard that someone makes a slip fit ball bearing for these older crankshafts. Part numbers would be helpful....google is getting confusing. Thanks!
