Hello all, I have a 1960 540 Case loader backhoe. I am wondering what the Hydraulic pump drive connects to as I do not have a 3 point hitch and it is plated closed. The Parts manual and service manual does not show what the gear connects to, and it is a backhoe loader with an external hydraulic pump? It has a dry clutch and a shuttle NO case-o-matic. I am very confused. Also, the throw out bearing is on the pump drive that is connected to the pressure plate by spline so rides on a live shaft. Anyone with any ideas as to how this live shaft and throw out bearing work together as my throw out bearing carrier is way dished out from the yoke when disengaging the clutch disk, the bearing unit is spinning against the yoke that is not spinning?
