1. Gather the necessary tools and materials:
- New oil filter (Harley-Davidson Part Number 63731-98)
- New O-ring for the oil filter (Harley-Davidson Part Number 25416-99C)
- Oil drain pan
- Funnel
- Wrench
- Rags
2. Prepare the motorcycle:
- Warm up the engine for a few minutes to thin the oil and make it easier to drain.
- Turn off the engine and allow it to cool down slightly.
- Place the oil drain pan under the motorcycle, directly beneath the oil drain plug.
3. Locate the oil drain plug:
- The oil drain plug is located on the bottom of the engine, on the left side. It is a 17mm bolt.
4. Remove the oil drain plug:
- Use the wrench to loosen the oil drain plug and allow the oil to drain into the oil drain pan.
- Allow all of the oil to drain out (approximately 3.7 quarts).
5. Replace the oil drain plug:
- Once all of the oil has drained out, replace the oil drain plug and tighten it securely with the wrench.
6. Locate the oil filter:
- The oil filter is located on the right side of the engine, near the top. It is a cylindrical-shaped object with a black cap.
7. Remove the oil filter:
- Use the wrench to loosen the oil filter and remove it from the engine.
- Discard the old oil filter.
8. Install the new oil filter:
- Apply a thin coat of new oil to the gasket surface of the new oil filter.
- Screw the new oil filter onto the engine until it is snug.
- Do not over-tighten the oil filter.
9. Add new oil to the engine:
- Use the funnel to add new oil to the engine.
- Add approximately 3.7 quarts of new oil.
10. Check the oil level:
- Use the dipstick to check the oil level.
- The oil level should be between the "Full" and "Add" marks on the dipstick.
11. Start the engine and let it run for a few minutes:
- This will circulate the new oil throughout the engine and help to ensure that there are no leaks.
12. Check for leaks:
- Inspect the motorcycle for any leaks. If you see any leaks, tighten the oil drain plug or oil filter until the leak stops.
NOTE: Be sure to properly dispose of the old oil and oil filter in accordance with local regulations.
