Replacing a Lippert hydraulic pump motor is a crucial maintenance task for RV owners. Whether you're dealing with a failing motor or looking to upgrade your system, this comprehensive guide will walk you through the process step-by-step. We'll cover everything from identifying the problem to successfully installing a new motor, ensuring your RV's hydraulic system operates smoothly.
Before diving into the replacement process, it's essential to understand the role of the hydraulic pump motor in your RV's system. The Lippert hydraulic pump motor is responsible for powering the leveling jacks and slide-outs in many RVs. When this motor fails, it can lead to issues such as slow operation, unusual noises, or complete failure of the leveling and slide-out systems.
The Lippert hydraulic system consists of several key components:
1. Hydraulic Pump Motor: The heart of the system, responsible for powering the hydraulic fluid movement.
2. Hydraulic Reservoir: Stores the hydraulic fluid.
3. Valves: Control the flow of hydraulic fluid to different parts of the system.
4. Hydraulic Lines: Transport the fluid throughout the system.
5. Cylinders: Convert hydraulic pressure into mechanical force to move jacks and slide-outs.
Understanding these components can help you better diagnose issues and perform maintenance on your RV's hydraulic system.
Common indicators that your Lippert hydraulic pump motor may need replacement include:
- Slow or inconsistent operation of jacks or slide-outs
- Unusual noises during operation
- Complete failure to operate
- Motor feeling warm or hot to the touch after brief use
- Burning smell coming from the motor area
- Visible damage or corrosion on the motor
If you notice any of these signs, it's time to consider replacing your hydraulic pump motor.
Before starting the replacement process, gather the following tools and materials:
- New hydraulic pump motor (compatible with your RV model)
- Socket set and ratchet
- Wrench set
- Screwdrivers (flathead and Phillips)
- Allen wrench set
- Pliers
- Wire cutters/strippers
- Electrical tape
- Clean rags
- Safety glasses and gloves
- Multimeter (for testing electrical connections)
- Hydraulic fluid (as specified by your RV manufacturer)
- Funnel
- Catch pan (for any hydraulic fluid spillage)
Having all these tools and materials ready will make the replacement process smoother and more efficient.
Before beginning any work, ensure your RV is parked on a level surface and the engine is off. Disconnect the RV from its power source and engage the parking brake. It's also a good idea to chock the wheels for added safety.
The hydraulic pump is typically located in the RV's basement area or under a slide-out. Consult your RV's manual if you're unsure of its exact location. Once found, clean the area around the pump to prevent debris from entering the system during replacement.
Locate the power connections to the pump motor. There should be a positive and negative wire. Carefully disconnect these, making sure to label them for easy reconnection later. Use a multimeter to verify that there's no residual power in the system.
The solenoid is usually attached to the motor with a hose clamp. Loosen this clamp and carefully remove the solenoid, being mindful of any hot wires. Take note of the solenoid's orientation for proper reinstallation later.
Remove the Allen screws holding the motor to the pump. There are typically two screws, one on the top and one on the bottom. Use your Allen wrench to remove these. Keep these screws in a safe place as you'll need them for the new motor.
Carefully pull the motor away from the pump. You may need to wiggle it gently to free it. Be cautious not to damage the shaft or any surrounding components. If there's resistance, double-check that all fasteners have been removed.
Before installing the new motor, compare it to the old one to ensure it's the correct replacement. Clean the contact area where the motor meets the pump. This is also a good time to inspect the pump for any signs of wear or damage.
Carefully align the new motor with the pump, ensuring the shaft is properly inserted. Replace and tighten the Allen screws to secure the motor. Be careful not to over-tighten, as this could damage the motor housing.
Place the solenoid back onto the new motor and secure it with the hose clamp. Make sure it's positioned for easy access and in the same orientation as before.
Reconnect the power wires to the new motor, ensuring you connect positive and negative correctly. Double-check all connections and use electrical tape to insulate any exposed wires.
Once everything is reconnected, turn on your RV's power and test the hydraulic system. Extend and retract your jacks and slide-outs to ensure smooth operation. Listen for any unusual noises and check for leaks around the new motor and connections.

While replacing the motor is often necessary, there are alternative solutions you should consider:
In emergency situations, you can manually operate your jacks and slide-outs using a drill adapter. This method is described in the video tutorial and can be a temporary solution to get you moving.
Sometimes, the issue may be with the motor's brushes rather than the entire motor. Replacing these can be a cost-effective solution for a temporary fix. However, this requires some technical knowledge and may not be suitable for all users.
Consider using an American-made replacement motor from companies like Western Motor. These are often more durable and cost-effective compared to OEM parts. They may also come with better warranties and customer support.
To prolong the life of your new hydraulic pump motor:
- Regularly inspect the system for leaks or loose connections
- Keep the motor and surrounding area clean and free of debris
- Avoid overworking the system by using it sparingly
- Ensure your RV's batteries are always well-charged when operating the hydraulic system
- Check and top up hydraulic fluid levels as recommended by the manufacturer
- Operate your jacks and slide-outs at least once a month to keep the system lubricated

Even after replacement, you may encounter some issues. Here are some common problems and their solutions:
- Check hydraulic fluid levels
- Inspect for leaks in the system
- Verify valve operation
- Ensure proper alignment of the motor
- Check for loose fasteners
- Verify that the shaft is properly seated
- Check battery charge levels
- Inspect hydraulic lines for kinks or obstructions
- Consider flushing and replacing hydraulic fluid
When replacing your hydraulic pump motor, it's important to dispose of the old motor and any hydraulic fluid properly. Many auto parts stores and recycling centers accept used motors and fluids. Never dump hydraulic fluid in the ground or water sources, as it can cause significant environmental damage.
Replacing a Lippert hydraulic pump motor may seem daunting, but with the right tools and guidance, it's a manageable task for many RV owners. By following this guide, you can save on repair costs and ensure your RV's hydraulic systems continue to function smoothly.
