Replacement motor service kit for select Power Gear hydraulic leveling system pump assemblies, including compatible vertical and horizontal pump assembly applications.
The Lippert 359303 is a hydraulic pump motor service kit used as a replacement motor for select Power Gear hydraulic leveling system pump assemblies. It is intended to restore pump motor operation when the original motor has failed or can no longer operate the leveling hydraulic pump properly.
This is a fitment-specific replacement motor, not a universal hydraulic pump assembly. It should be matched by the existing Power Gear pump assembly number, manufacturer reference number, motor configuration, mounting, wiring, and hydraulic system application before ordering.
Replacement motor for select Power Gear hydraulic leveling pump assemblies
Lippert references Power Gear manufacturer number 800302 for this motor
Commonly listed for vertical assemblies 3510000161, 501090, and 501234
Commonly listed for horizontal assemblies 1010001480 and 3510000152
Lippert 359303 is not a universal leveling pump motor. It must be matched to the correct Power Gear hydraulic pump assembly and leveling system configuration. Verify the pump assembly number, motor label, Power Gear reference number, vertical or horizontal pump style, mounting pattern, shaft/pump interface, wiring, solenoid setup, and hydraulic system before ordering. Similar-looking hydraulic pump motors may not interchange.
Before Starting: Confirm the existing pump assembly is one of the compatible Power Gear references and that the motor is the failed component. Hydraulic leveling systems can move unexpectedly, and high-current electrical circuits are involved. Support the coach safely and disconnect power before service. Basic Replacement Steps: 1. Confirm Fitment: Match the existing pump assembly number, Power Gear reference number, motor label, mounting pattern, and wiring configuration. 2. Secure the RV: Park on stable ground, chock wheels, and make sure the leveling system is safely positioned before service. 3. Disconnect Power: Disconnect battery power or the leveling system power supply before removing the pump motor. 4. Document Wiring: Photograph wire routing, terminals, solenoids, grounds, and motor orientation before disassembly. 5. Remove Existing Motor: Remove electrical connections and motor mounting hardware according to Power Gear/Lippert service instructions. 6. Inspect Pump Assembly: Check the pump interface, mounting surface, coupler/drive interface, fluid leaks, wiring, solenoids, and nearby hydraulic components. 7. Install Replacement Motor: Install the new motor in the same orientation and secure it properly without forcing alignment. 8. Reconnect Wiring: Reconnect wiring as documented, confirming clean terminals, proper ground, and correct polarity/connection points. 9. Test Operation: Restore power and test the leveling system in short cycles while watching for leaks, abnormal noises, weak pump operation, or error indicators.
Package Contents: • 1 Lippert 359303 hydraulic pump motor service kit • Motor-only service components as supplied by Lippert packaging NOT Included — May Also Need: • Complete hydraulic pump assembly • Hydraulic reservoir or pump manifold • Leveling jacks or cylinders • Hydraulic hoses or fittings • Solenoids, coils, valves, or relays • Leveling control module or touch pad • Fluid sensor / float switch components • Hydraulic fluid • Battery cables, fuses, breakers, or wiring repair parts • Installation tools and electrical test equipment This listing is for the hydraulic pump motor service kit only unless otherwise stated. Confirm the motor is the failed component before ordering.
To confirm compatibility before ordering, have the following ready: • Existing pump assembly number • Existing motor label and reference numbers • Whether the pump assembly is vertical or horizontal • RV year, make, model, and chassis if available • Power Gear/Lippert leveling system model or documentation • Photos of the motor, pump, reservoir, solenoids, wiring, and mounting area • Symptoms, such as no pump operation, clicking solenoid, weak motor, blown fuse, or jack movement issues • Battery voltage and any diagnostic codes from the leveling system Why this matters: A hydraulic leveling failure may be electrical, hydraulic, mechanical, or control-related. Replacing the motor will not correct issues caused by low voltage, bad solenoids, stuck valves, low fluid, leaking jacks, bad controls, or damaged wiring.
Match this motor by Power Gear reference number, pump assembly number, vertical/horizontal pump configuration, mounting, wiring, and confirmed motor failure. Do not select it by appearance alone.
If the leveling system still does not operate after motor replacement, check battery voltage, solenoids, relays, fuses, breakers, grounds, controller output, fluid level, valve coils, hydraulic leaks, jack condition, and Power Gear diagnostic guidance.
Hydraulic leveling systems support and move heavy RV components. Improper service can cause injury, electrical damage, hydraulic leaks, jack movement, or loss of leveling function. Disconnect power before service, support the RV safely, avoid working under an unsupported vehicle, keep hands clear of moving components, and follow Lippert/Power Gear service instructions. Use a qualified RV technician if electrical diagnosis, hydraulic service, or leveling system fitment is uncertain.
