Hi,

Looking for an OEM right side crank seal for my '76 MR250, really hard to find. Does anyone know where I can get one? Chasing huge amounts of smoke out the exhaust. I have it torn down, crank surface looks ok, want to replace seal and gaskets and then pressure test.

Any help welcomed.

Thanks, Mark

Hi,

I have searched ebay and not found the links you sent, thanks. I have tried two major bearing and seal companies and they can't get it. Also, this seal is different since it handles oil on 1 side and up to 9 PSI on the other so I will get a NOS from Ebay.

Thanks for your reply with the link, I'll post how it turns out. Bike has only 936 miles on it, absolutely stock right to the tires (and maybe the air in them). Need to replace them once I can ride it again.

HI,

I have found and purchased a NOS seal and a gasket set. Need to jump over the US border and pick up the seal. It was $12 US for the seal and $22 US for mailing it to me!!!!!!

Anyway, thanks to all and I'll update when I have it pressured tested and running.

Mark
