Top and bottom end rebuild

[atvfreestylekid]

I am installing a hotrods stoker crankshaft because a rod bearing blew and ended up screwing the stock crank up. But when the bearing blew up, the pieces fell under the crank and got wedged up between the crank and the case. It's scratched up a little. This won't realy hurt will it? The case is still perfect where the crank bearings sit so I'm sure the case is fine. But want more opinions. Another question is will the stock yamaha wrist pin bearings work with this hot rods crank and wiseco 795 pistons? All I can find are stock bearings. What is the best stuff to use to seal the case? I've heard of yamabond and hondabond. Either of these any good or is there better stuff? Any replies appreciated. Thanks

I wouldn't worry about the cases if it is only scratches, not major deformation. Make sure to clean and inspect the cases carefully. Yamabond works great for sealing the cases, make sure the sealing surfaces are clean and oil free. It is hard to keep them oil free if you put oil on everything when you assemble the cases, I don't lubricate anything I don't have to before assemblying the cases.

Yeah, what he said.
