Greetings lubeheads. I am trying to remove the hydraulic pump that is currently attached to my rear PTO on my Kubota B7100. It runs the backhoe, and I'm supposed to put it on and take it off when attaching or detaching the backhoe. Just bought the rig and wanted the backhoe off quickly, and knew I was going to change up all the fluids, so I just removed the hoses and defered the pump removal (which initially seemsed tricky) to another day. Today is the day.
As you can see in this photo, the pump is coupled to the pto shaft with an odd cylindar and a fitting that look like an attachment pin. As you cannot see in these photos, there are also two set screws, about 5/32". I have tried to remove these set screws and found them completely frozen and I believe I have now stripped out the hex fittings. I suppose I will have to drill them out and re-drill/tap new holes for new set screws.
But this odd "attachment pin" thing has me baffelled. It doesn't push in, doesn't pull out, doesn't seem to turn, at least not without snapping a toothy vicegrip on it (which I really don't want to do right now). The back side of the pin seems to be a blind hole. What exactly is this and how does it work? Given it's location, I am sure that this thing is key to my removing the hydraulic pump, but before I exert any real force on it (a bang in with a hammer, a vicegrip pull out or turn), I though I'd ask someone who has seen one of these things before.....
