Crank seal question


Kevref

Recommended Posts

Just fired up my fully rebuilt GS750 and oil is leaking from the right side crank seal.

Brand new seals used throughout.: correctly torqued crankbolts… 

wasnt leaking before stripdown and new rebuilt crank installed..

Damn damn annoying !!!!

I never put yamabond around a seal… but my rebuild  experience is all 2 stroke… nothing different with these engines is there ??

I think you’ll be better off buying a new seal, taking the ignition trigger stuff out of the way and tapping the new seal in. If you split the cases again, the seal likes to stick to one half and if it favours the ‘wrong’ half, you’ll stretch it and wreck it anyway.

You didn’t say if it was leaking from around the shaft or between casing and seal.
