This is the OEM-matched hydraulic power unit for Power Gear leveling systems designed around horizontally mounted, spring-return jack assemblies. If your rig uses a horizontal pump layout and your existing unit is leaking, running weak, or failing to hold pressure, 359269 is the direct drop-in replacement -- no repiping, no bracket fabrication.
Lippert Components (formerly Power Gear) produced horizontal hydraulic pump assemblies for a wide range of Class A motorhomes, fifth wheels, and travel trailers equipped with their automatic leveling systems. The 359269 unit mounts horizontally -- meaning the motor and pump sit parallel to the chassis rail rather than upright -- and is paired specifically with spring-return jack assemblies that retract automatically when hydraulic pressure is released.
Unlike generic aftermarket pumps, this unit ships with the correct port configuration, pressure-relief valve calibration, and reservoir capacity to work within the Power Gear system's solenoid valve block without modification. That matters at 2 AM in a campground when you need your slides in and your jacks up.
Correct fluid capacity for multi-jack Power Gear systems. Prevents cavitation under full extension cycles.
Motor axis runs parallel to mounting surface -- matches chassis compartments built for horizontal pump layouts.
Calibrated pressure relief for systems where jacks retract via internal spring, not hydraulic reverse flow.
Manufactured to original Power Gear specifications. Matches original port locations and solenoid block interface.
Power Gear produced two primary pump orientations: vertical (upright, often mounted in a bay floor area) and horizontal (motor lying on its side, often tucked against a frame rail or in a shallow compartment). Using the wrong orientation is not just a fitment issue -- it affects the reservoir's internal pickup tube position. Running a vertical-spec pump on its side will starve the pump of fluid. The 359269 is designed and plumbed for horizontal installation only.
Before ordering, verify your existing pump lies flat with the motor shaft horizontal. If your current pump stands upright, you need a vertical-mount variant instead.
Power Gear leveling systems are designed to run on automatic transmission fluid (ATF Dexron III / Mercon) or a dedicated hydraulic leveling fluid. Do not use standard hydraulic jack oil -- it does not contain the correct seal swell agents and can damage internal O-rings over time. When installing the 359269, drain and flush residual fluid from the lines before filling the new reservoir to avoid contaminating the fresh unit with degraded fluid.
Check the label on your existing pump -- Power Gear part numbers are typically printed on a foil sticker on the reservoir or motor housing. If your label is missing, note whether your pump is horizontal or vertical, count the hydraulic ports on the manifold, and measure your reservoir capacity. The 359269 has a 2.0-gallon reservoir and a horizontal motor orientation. Those two details will confirm or rule out this part for your system.
