Hello all.
The engine is a CB750 K0. After putting all the bolts to join the crankcases, when I was installing the cylinders and so on, I noticed that the final drive seal had slipped from its hole. I tried to punch it from outside, but I couldn't reach the bottom, so I splitted off the crankcases again. Why did it slip? I put some Threebond 1104 around the seal, expecting that it would seal better, but maybe that was the mistake and I should install it dry. I thought about making sort of a retainer to retain it from the outside of the engine. Anyone had that problem? Thank you.
