Stub shaft walk

[yamahar1]

Would this work to keep the oil pump gears from eating the case?






Could you not put a roller bearing in place of the rubber seal? Something like this or just some kind of spacer, like what is used on the balance shaft.



I would think that would hold it in place and give it the support it needs.....Yes? No? Maybe?

I'm not a engineer....so i would consult a shop very familar with building the motor. It may work but there is probably a reason for the original design.
