Keep your RV level and your slides moving with a direct-fit replacement motor for Power Gear hydraulic leveling pump assemblies. This OEM-equivalent service part restores full system function on both vertical and horizontal pump configurations without cutting corners on durability.
When the motor on your Power Gear hydraulic pump fails, the entire leveling system -- jacks, slides, or both -- goes down with it. Lippert part 359303 is the correct replacement motor designed specifically for the pump assemblies used in Power Gear hydraulic leveling and slide-out systems found across a wide range of RV brands and chassis configurations.
Rather than replacing the entire pump assembly, swapping the motor alone is a cost-effective repair that experienced DIYers and RV technicians routinely complete in the field. This motor is compatible with both vertical-mount and horizontal-mount pump configurations, making it one of the more versatile service parts in the Power Gear lineup.
Compatible with both vertical and horizontal Power Gear hydraulic pump assembly orientations.
Genuine Lippert part number 359303 -- sourced directly from the Power Gear product line.
Replaces just the failed motor component, preserving your existing pump body and hydraulic fittings.
Fits Power Gear hydraulic systems installed across many Class A, Class C, and fifth-wheel platforms.
This listing covers the hydraulic pump motor assembly (Lippert part 359303). The pump body, reservoir, hydraulic lines, mounting hardware, and fluid are not included. If you need the complete pump assembly or additional service components, verify your system's pump assembly part number before ordering.
The motor is the most common failure point in Power Gear hydraulic pump assemblies. Symptoms include the pump not activating when the leveling or slide switch is pressed, a clicking relay with no motor response, or a motor that hums but does not spin. If your relay and wiring check out, the motor is the next component to test and the most economical part to replace.
Lippert 359303 is designed for use with Power Gear hydraulic pump assemblies used in slide-out and leveling jack applications. Power Gear systems are common factory installations on units from manufacturers including Tiffin, Winnebago, Fleetwood, Forest River, and others. To confirm fitment, locate your pump assembly's existing part number label (typically on the pump body or reservoir) and cross-reference with Lippert's current compatibility chart or your RV's service manual.
Power Gear pump assemblies are installed in two primary orientations depending on chassis space and OEM configuration. The vertical pump mounts with the motor shaft pointing upward or downward; the horizontal pump mounts with the motor shaft oriented to the side. Part 359303 is designed to service both configurations -- confirm your pump assembly part number matches a 359303-compatible unit before ordering.
Motor replacement on a Power Gear hydraulic pump is a mechanical service procedure. General steps include:
Always depressurize the hydraulic system before removing the motor. Hydraulic fluid under pressure can cause injury. Collect any spilled fluid and refill the reservoir with the correct fluid type after reassembly. Dispose of used hydraulic fluid according to local regulations.
While servicing the motor, inspect the pump coupling, seal around the motor shaft, and hydraulic reservoir for leaks or debris. Contaminated hydraulic fluid accelerates pump wear -- if the fluid appears dark, milky, or contains particles, flush and refill the system as part of this service interval.
