Right side crank seal

May 23, 2002
I posted a thread a while ago about my 1991 CR 125. We came to the conclusion that the right side crank seal needed to be replaced. I pulled out the clutch and there is a retainer holding the crank bearing in place and I assume that the seal is behind the bearing. How am I supposed to pull out the bearing and then pull out the seal and then install it with the crank inplace and without splitting the cases? My clymer manual doesn't say how to replace them it just says to do it and in the picture the cases are split but this does not nnecissarily mean you have to split them.

Thanks for the help
