Applies to: Cummins/Onan P216, Cummins/Onan P218, Cummins/Onan P220
Before you start
- Hot exhaust parts can cause severe burns. Allow the engine time to cool before servicing the exhaust system.
- A clogged flywheel air inlet screen or dirty cooling fins can cause overheating and engine damage.
- Crankcase pressure can blow hot engine oil out the fill tube causing severe burns. Always stop the engine before removing the oil fill cap.
- Too much oil can cause high oil consumption, high operating temperatures and oil foaming. Too little oil can cause severe engine damage.
Procedure
- Inspect fuel lines and fittings for leaks; repair leaks immediately.
- Look and listen for exhaust system leaks while the engine runs; check muffler and tailpipe for cracks and severe rusting.
- Check the engine for dirt and debris; clean the flywheel air inlet screen and cylinder cooling fins as necessary.
- Check the engine oil level with the equipment on a level surface and the engine stopped; wait a minute for oil to settle.
- Turn the oil fill cap counterclockwise, lift it from the fill tube, wipe the dipstick clean, reinsert fully and withdraw to read the level.
- If low, add API Class SG or SH oil of the SAE viscosity grade appropriate for expected temperatures.
- Do not fill above the FULL mark on the dipstick; drain excess oil if too much was added.
- Reinstall the dipstick and cap, turning clockwise until secure.
