Hydro Gear 53738 Charge Pump Housing

Product Description

The HYDRO GEAR 53738 is a charge pump housing designed for use in hydrostatic transmission systems commonly found in residential and commercial lawn and garden equipment. The charge pump housing serves as the structural enclosure for the charge pump assembly, maintaining proper fluid containment and internal pressure to support transmission operation. This component is an OEM-style replacement part installed by equipment technicians and powertrain service professionals working on hydrostatic drive systems.

The 53738 charge pump housing is suited for lawn and garden applications where HYDRO GEAR hydrostatic transmissions are in service. Typical install scenarios include zero-turn mowers, riding lawn tractors, and similar turf equipment that rely on hydrostatic drive units for variable-speed ground propulsion. It is a direct replacement component intended to restore proper transmission function when the original housing is damaged, cracked, or otherwise compromised.
