1995 polaris xplorer 400 4×4. The piston broke and knocked a hole in the crankcase. I have another crankcase but I need to tear my old one apart so I can get the crank out. I’ve looked on the internet but haven’t had much luck finding anything on how to take it apart. Does anyone know of some tricks or things to watch for? Or possibly some links on how to do this. Any help would be great. Thanks
