its not insurmountable though.....there are pics in the Eric Gorr tuning book of seal areas that have been repaired by welding on race bikes, so its not uncommon.just find someone who knows their stuff.kxr member Roostius Maximus will probably know someone, if he can't do it himself...hth.K.

This bearing and seal removal has made me wondering about two things.

How to press the new bearings in without damaging them, the old ones sat really tight.
But i guess it should work with a big socket.

And how the bearings can be installed to the right place, as they sit on the inner end of the seat, while the seals sit on the outer side, with about 5mm of space in between.
Don?t understand how that distance can be kept when sliding the frozen bearing in or pulling the crank in?!

the outer bearing race sits against the case, with space inside for the seal.K.

More and more novice questions come to my mind, although i thought i was the best mechanic in the world  :-D

Heating the case and freezing the main bearing for assembly, sounds like a plan.
But heating the case with the main seal already installed?!

You explained how to keep the heat away from the seals when installing the crank to the mains, but not how to do it when installing the mains to the cases?!
(Maybe i didn?t get that right, english isn?t my mother tongue...)
