Hi,
I知 trying to put live hydraulics on my tractor this winter and I知 starting with the pump. A friend has a small CW pump so I was wondering if I can mount to the crank pulley and run it in reverse. I know it pumps but will this affect the PSI or GPM?
Thank again,
Larry

I moved the belt driven gear type hydraulic pump on my D grader to run off the end of the crankshaft. I could not find any markings on the pump to indicate that it was not bi-directional and looking at the blowup in the parts book it looked to be very simple and totally symmetrical so I gambled that it would work rotating in the opposite direction. So far it has been fine. The shaft seal does seep a tiny bit now and it didn't before. It has roller bearings and not bushings.

Most hydraulic pumps can have the rotation reversed by turning the end plated around. Check with your local hydraulic shop if you want to be sure.

normally the gear pump has shaft bushings on each end of the gears. the bushings have a small groove to the pressure side of the pump to get lube for the bearings (bushings). If you run backward, the bushings are under suction, not pressure.... You can put the pump under the radiator with the shaft pointing forward under the crank, Then put a shaft in the crank hole and run a chain and sprocket around shaft and pump.

Thanks,
I"ll see about chain/belt driven first. Otherwise I may buy a new CCW pump.
