I hope someone out there has changed a pto oil seal on a kubota L2050? I unbolted 4 bolts and the pto plate cover will turn side to side but will not slide off. The parts diagram shows a slinger first? I'm wondering if this is whats stopping the cover from coming off. I never herd of a slinger and do not no how you remove it. If any body has replaced a seal please help me get this cover plate off. Thanks Randy
