I recently have tore apart a four wheeler for the first time i have the top end completely apart and am about to split the cases to replace the right side casing bc it has some damage. How difficult will splitting the cases be and transferring all of the gears, bearings , and more to the other case? I already have the clutch basket,primary drive gear,oil pump, and stuff out. now I just have to split the cases and remove and swap the internal stuff. how hard will this be?
