The Permco 5100 Gear, part number 51A431ADSP2514, is a gear component for Permco 5100 Series PTO hydraulic pump applications. In a gear-type hydraulic pump, a gear and shaft set turns in mesh with its mate to carry oil from the inlet side to the outlet side, so the condition of the teeth decides how well the pump holds its output. Worn gears or worn bearings inside a pump can show up as grinding or whining noise and weaker output, and a pump that runs hotter than normal or loses pressure is also worth a look. A genuine Permco part, sold individually by Pro Gear and Transmission. Call us to confirm proper fit for your pump.
