55C531AAZA2014 Permco hydraulic pump is a PTO-driven hydraulic pump for heavy-duty truck systems. In the gear pump design common on PTO-driven systems, the pump turns the mechanical energy it receives from the PTO into a flow of oil. A drive gear and a driven gear mesh, carrying oil between the teeth and the housing from the inlet side to the outlet that feeds the system. The pump makes flow only, and pressure builds from resistance in the hydraulic system. Excess heat, or a system that no longer performs the way it used to, can mean a worn pump is due for replacement. Sold by Pro Gear and Transmission. Call us to confirm proper fit.
