Hypro 3220-0029 — Bypass Adjusting Valve Stem, HM1C-HM5C Hydraulic Motors (9302 / 9303 / 9306 Pumps)

Hypro 3220-0029 is the bypass adjusting screw, also called the valve stem, in the HM1C through HM5C hydraulic motors used on Hypro 9302C/S, 9303C/S, 9306C/S and 9303P series hydraulically driven centrifugal pumps. It is the precision-machined stem you turn to set how much hydraulic oil bypasses the gerotor, which sets pump speed on an open-center tractor hydraulic system. Replace it when the stem is bent, the tip is worn so the pump speed will not hold or adjust smoothly, or the threads are damaged. It seals with the 1700-0047 gasket, 2270-0027 washer and 2250-0038 lock nut.
