I have an '02 WR426 - the right side crankcase cover cracked on my last ride (I can't figure out how). Anyway, I ordered a new one but can't seem to remove some of the bearings and seals in the old one. Is it an issue of brute force? Do I have to buy new seals and bearings? I don't mind that, I guess, but the local dealer here is terrible and never has any inventory. I don't want to wait another two weeks if I can help it. Any help/hints would be greatly appreciated from this newbie.
