The Permco 55C551AAXQ225 is a 5151 Series hydraulic pump with a DIN mount configuration, intended for PTO hydraulic applications. Gear-type pumps like this one work by running a driven gear against a mating gear inside a close-fitting housing, so oil is carried around the teeth from the inlet side to the outlet side and leaves under pressure. On a truck the pump is normally spun through a power take-off, which lets the engine and transmission feed lift cylinders or hydraulic motors on the body.
A tired pump usually announces itself with added noise and vibration, slower lifting, lost pressure and extra heat. Weeping at the shaft seal or fine metal in the oil also points to wear inside. Call us to confirm proper fit for your application.
