Upon replacing the two gaskets and the seal on my Super H's lift all(not live), I put the lift all back in the tractor. I started the tractor and when I was engaging the clutch, the tractor almost died! The pump was TIGHT! I thought a chip of metal was in between the teeth, so I took the actual pump apart to inspect it. I did find the tip of the screwdriver I used to jam the gear teeth while taking the coupling nut off so I could replace the seal(laughter... a scared sort of laughter...). Anyway, I put the pump cover on and tightened up the eight bolts and still the pump was too tight to move. loosen bolts, try again, same result. tried that a couple of times. the last time I tried that, I tightened each bolt slowly and the gears turned reasonably well, until I got where I wanted the bolts to be and at that moment the pump again tightened or seized up. The pump worked excellent before I replaced the seal and gaskets. I'm thinking that there must be a burr on the bottomside of the gears that is causing the binding, but I became discouraged and didn't want to take the pump apart again, plus I figured you guys could come up with some ideas. Also, is there a specific torque that the pump cover bolts are supposed to have?
