I was replacing my seal #2 below when I removed it the sleeve #36 just slid right out. Is that supposed to happen? Should the sleeve just pull right off the shaft? It came off when I took the seal off so I'm not sure exactly how it goes back on. Any help would be appreciated. Does the sleeve #36 just rid freely on the shaft? Or will I have to take the shaft out and squeeze it on somewhere? What does it do? Just keep it centered in the case? Does anyone have a picture of the mid pto assembled? Thanks everyone.
