Locate the air filter housing on your generator. Open the housing, remove the old air filter (Onan PN: 140-3280), and replace it with the new filter from the kit. Ensure the new filter is seated correctly and close the housing securely. This helps maintain proper air intake and engine efficiency.

Identify the fuel filter location on your generator. This component (Onan PN: 149-2457) may be difficult to access. Before disconnecting any fuel lines, ensure the generator is off and cool, and take precautions to prevent fuel spillage. Disconnect the fuel lines from the old filter, remove it, and install the new fuel filter, ensuring the flow direction is correct. Reconnect the fuel lines securely. Be prepared for some fuel to escape during this process.

Spark Plug Replacement and Gapping
Locate and carefully remove the existing spark plug. Before installing the new spark plug (Onan PN: 167-0275), use the included GPS Spark Plug Gap Tool (PN: 627-0550) to verify and adjust the gap to the specification provided in your generator's manual. Due to limited space, a spark plug socket with a hex on the outside, used with an open-end wrench, may facilitate installation. Install the new spark plug and torque it to the manufacturer's specifications.

Oil Selection
The kit includes documentation for proper oil selection. Consult this documentation and your generator's manual to choose the correct oil viscosity based on your operating temperature range. Note that many Onan RV generators, particularly propane models, do not utilize an oil filter.
Загальний графік технічного обслуговування
It is recommended to perform a tune-up and replace these components every 500 hours of operation or annually, whichever occurs first, to ensure consistent generator performance.
Усунення несправностей
If your generator experiences issues after maintenance, consider the following:
- Fuel Vent Line Obstructions: Inspect the fuel regulator vent line for blockages caused by insects or debris. A clogged vent line can prevent proper fuel regulator function.
- Іскрогасник: While less common with propane generators, check the muffler's spark arrestor for excessive carbon buildup if performance issues persist.
- Безпечні з'єднання: Ensure all fuel lines, electrical connections, and filter housings are properly secured after maintenance.
If problems persist, consult your generator's specific service manual or contact a qualified generator technician.
