Ok so I have a 1956 Minneapolis Moline 445 universal. I recently rebuild the hydraulic pump being extremely careful not to damage the plates or internal components. The IT manual claims that the "early" style pump, which I have, isn't serviceable. I put it back on the tractor and when I cycle the 3 pt hitch fluid starts to spew from the top 3 bolts and between the outer and center plates. Has anyone had experience with this pump? I would like to see an exploded view of the pump because my manuals don't provide one, torque specs of the pump bolts and if there is supposed to be some type of gasket in the machined "groove" between the outer and center plate. Thank you.
