Removing an Onan Generator from an RV: A Step-by-Step Guide

If you're facing issues with your Onan generator in your RV and need to get it repaired, you may have to remove it from the RV and take it to a service center. In this guide, we'll walk you through the process of safely removing the generator from your RV. Follow the steps closely to ensure a smooth removal process.

1. Introduction

Removing an Onan generator from an RV is not an easy task, especially considering the limited space and tight fits. However, with proper preparation and the right tools, you can successfully remove the generator without causing any damage to your RV or yourself.

2. Preparing for Generator Removal

Before you begin the removal process, there are a few steps you need to take to ensure a smooth operation.

Unhooking the Battery Cable

The first step is to unhook the battery cable to cut off the power supply. Locate the battery cable and disconnect it carefully to avoid any electrical mishaps.

Unhooking the Fuel Line

Next, you need to unhook the fuel line. Depending on your RV's generator model, you may have one or two fuel lines. Ensure you safely unhook both lines and prepare to plug them to prevent any fuel leakage.

Unhooking the AC Power

Lastly, unhook the AC power connection to ensure no power is supplied to the generator during the removal process. This step is essential for your safety and to prevent any potential damage to the generator.

3. Unbolting the Generator

Once you've completed the preparation steps, it's time to start removing the generator. Begin by unbolting the generator from underneath the RV. Locate the four bolts that hold the generator in place and carefully remove them using the appropriate tools.

4. Removing the Exhaust

To create more space and maneuverability, you'll need to remove the exhaust. Loosen the clamp that holds the exhaust in place and slide it off. Be cautious with any connections and take necessary safety precautions while removing the exhaust.

5. Unhooking the Fuel Lines

Since Onan generators are fuel-injected, you'll have two fuel lines – a supply line and a return line. Carefully unhook both fuel lines, ensuring you have the appropriate tools to loosen the clamps. To prevent any fuel leakage, plug the fuel lines securely.

Plugging the Fuel Lines

Take 5/16 bolts with collars and slide them all the way into the fuel lines. Tighten the clamps to seal the fuel lines effectively. This will prevent any leaks or fuel spillage during the removal process.

Labeling the Fuel Lines

To avoid confusion when reinstalling the generator, label the fuel lines as "supply" and "return." This simple step will save you time and effort when reconnecting the fuel lines after the repair.

6. Moving the Generator

By this point, you may realize that the generator is larger than the hole it needs to come out of. To create more space, you'll need to move the generator by adjusting the surrounding wall. Carefully remove any screws or components that hold the wall in place, allowing you to move the generator slightly.

7. Removing the Wall

Take necessary precautions and start removing the wall that obstructs the removal of the generator. Be cautious not to damage any surrounding components or structures as you remove the wall.

8. Unhooking the Remote

Locate the remote connection and unhook it carefully. This is usually a plug or wire that goes into the generator. Gently work it through the hole to completely detach it.

9. Unhooking the Power

Disconnect any power connections that go into the generator. Loosen the screws on the power box cover and remove the cover to access the wires. Unhook all the wires connected to the generator, ensuring everything is completely detached for the removal process.

10. Removing the Generator

With all the preparations and unhooking complete, it's time to remove the generator. Use a floor jack or other lifting equipment to raise the generator, allowing you to maneuver it out of the tight space. Carefully lift and twist the generator to slide it out of the compartment.

11. Conclusion

Removing an Onan generator from an RV requires careful planning, preparation, and execution. By following the step-by-step guide outlined above, you can successfully remove and transport the generator for repairs. Ensure you take all necessary safety precautions and seek professional assistance if needed.
