5. Remove the rear cargo box panel.
6. Remove any debris near the oil cap and remove the oil cap.
7. Place a drain pan under the engine crankcase. Tip: Place a rag in the bottom of the drain pan to prevent splashing of oil.

13. Using a clean dry cloth, clean the filter sealing surface on the crankcase. Make sure the old filter O-ring is completely removed.
