When your RV's leveling jacks or slide-out rooms stop responding, the hydraulic pump motor is often the culprit. Lippert part #167576 is the OEM-spec replacement motor for Lippert hydraulic power units -- a permanent magnet, bi-rotational 1 HP, 12V DC motor engineered to restore full hydraulic function without custom fabrication or wiring modifications.
Lippert's hydraulic leveling and slide-out systems are among the most common found in Class A motorhomes, fifth wheels, and large travel trailers. Over time, the pump motor can wear out from repeated cycling, voltage spikes, or corrosion -- especially in rigs that see heavy use or extreme temperature swings. The 167576 motor is a true direct replacement that matches the OEM mounting, shaft, and electrical interface of the Lippert power unit assembly.
Bi-rotational design means this motor can drive the hydraulic pump in either direction, which is essential for systems that must both extend and retract jacks or slides using the same pump circuit. The permanent magnet construction delivers high torque on demand while drawing current efficiently at 12V DC.
High-torque output handles the load demands of multi-jack leveling and full-travel slide-out systems.
Runs in both directions -- no relay reversal needed at the motor level. Essential for extend-and-retract hydraulic circuits.
Matches the 12V DC electrical system standard in virtually all towable and Class A motorhome hydraulic installations.
Confirmed compatibility with Lippert hydraulic power unit assembly #141111 and a wide range of related Lippert pump assemblies.
Standard DC motors are wound to spin in one direction. A bi-rotational (also called reversible) permanent magnet motor is engineered to spin reliably in either direction depending on how polarity is applied. In Lippert's hydraulic systems, this allows a single pump motor to pressurize fluid for both the extend and retract strokes of leveling jacks and slide-out rams -- reducing system complexity and cost compared to dual-motor designs.
When replacing a hydraulic pump motor, it is critical to match not just the horsepower and voltage but also the shaft diameter, frame size, and rotation capability. Swapping in a unidirectional motor will cause one-way failure in the field.
Lippert part number 167576 is sourced directly from Lippert Components. It is the same motor used in factory-installed Lippert hydraulic power unit assemblies. No shaft adapters, custom brackets, or wiring harness modifications are required when replacing a failed OEM motor on a compatible unit.
Confirm the motor is the failed component before ordering. Check the hydraulic fluid level, inspect wiring connections and ground straps for corrosion, and verify battery voltage under load is above 12.2V. A healthy motor drawing full current on a weak battery will often appear to fail. Use a multimeter to confirm the motor terminals are receiving 12V+ during activation before condemning the motor.
Replacing the pump motor on a Lippert hydraulic power unit is a straightforward mechanical swap on a level work surface with the hydraulic system fully depressurized and the rig safely supported. Key steps include:
Do not work under raised jacks or extended slides supported only by hydraulic pressure. Always use mechanical blocking and safety stands rated for the weight of the coach before performing any work on the hydraulic power unit. Hydraulic fluid under pressure can cause injection injuries.
After installing the new motor, cycle the leveling system through a full extend-and-retract sequence at least twice and check the hydraulic reservoir fluid level. Inspect all hose connections and the power unit reservoir for any weeping. Note the current draw with a clamp meter if possible -- a healthy Lippert pump motor at 1 HP typically draws 80-120 amps under full load at 12V DC. Elevated draw indicates a mechanical restriction; low draw with poor pressure suggests a pump wear issue separate from the motor.
