Good morning AS junkies. I am not exactly sure what i am looking for but i am sure some gurus out there can help. I recently built a 562xp and i am having some issues/questions concerning oil pump drive and/or clutch drum. I have a 562xp clutch drum and i have tried using the PN 577 60 11-01 and 586 20 46-01 oil pump drive (all new OEM) and the oil pump drive cogs/dogs whatever you call it do not seem to want to fully engage with clutch drum. So if i were to install either one of the oil drives with my current clutch drum and pull outward on clutch drum, it will disengage for the oil pump drive. I have 2 ea clutch drums and they both do the same thing. Its like husky made 3 different oil pump drives and 3 different clutch drums. What exactly am i missing here? I cannot even start saw with it like this as it will most likely strip out plastic oil drive. Any help would be appreciated. thanks
