Are there any directions on removing the crankcase? Google searching brought me here, so I signed up in the hopes that there was a thread already. However, I was not able to find it, if there is one. I have to rebuild the entire engine because the shops quoted me $10,000 to rebuild. I found the upper engine for $700, and the lower for $2,300. I have a 2010 800 RZR Walker Evans Edition.
