Well, after almost 14 years of solid reliability, my 2007 cr finally had a major failure. My countershaft bearing came apart and cracked the case pretty bad last weekend at E-street. I plan on replacing the left side case and whole rotating assembly but my questing is, should I replace both cases? The right side doesn’t appear to be broken but who knows what I’ll find when I split them apart. Also, does anyone know if new oem cases come with bearings already installed? I was going to order a wrench rabbit kit but according to the parts diagram on motosport, it appears the bearings are all included in the cases halves? If they are included, I will most likely end up going with a new oem crank.
You should plan to vapor blast the old, right case as it is likely stained from years of dirt and will look pretty bad next to the brand new left case. I've done this exact fix before and the owner didn't care about looks and it sure looked pretty ridiculous. In the end, you'll probably want to blast everything.. cylinder, clutch cover, etc so it all looks new and consistent.
