Changing the oil on a Harley Davidson 103 engine involves several steps. Here's a general guide to help you through the process:

Note: It's always a good idea to consult your owner's manual for specific instructions and any model-specific variations.

  1. Gather the necessary tools and materials:

    • New oil filter (compatible with your Harley Davidson 103 engine)
    • The appropriate type and amount of oil (check your owner's manual for specifications)
    • An oil drain pan
    • A socket wrench with the correct socket size for the drain plug
    • A filter wrench (if needed)
    • A clean rag or shop towels
    • A funnel
  2. Warm up the engine:

    • Start the motorcycle and let it run for a few minutes to warm up the oil. Warm oil flows more freely and helps remove contaminants.
  3. Position the motorcycle:

    • Place the motorcycle on a stable surface, ensuring it's level and upright.
  4. Locate the oil drain plug and oil filter:

    • Consult your owner's manual to find the exact location of the oil drain plug and oil filter. Typically, the oil drain plug is located on the bottom of the engine, while the oil filter is mounted on the side.
  5. Drain the oil:

    • Position the oil drain pan beneath the drain plug.
    • Use the socket wrench to loosen and remove the drain plug. Be cautious as the oil may be hot.
    • Allow the oil to drain completely into the pan.
    • Inspect the drain plug for any debris or metal shavings, which could indicate a problem with the engine.
  6. Replace the oil filter:

    • Use the filter wrench to remove the old oil filter, if necessary.
    • Take a small amount of fresh oil and lubricate the rubber gasket on the new oil filter.
    • Install the new oil filter by hand, tightening it according to the manufacturer's instructions. Do not overtighten.
  7. Refill with fresh oil:

    • Locate the oil fill cap, usually on the side of the engine.
    • Using a funnel, pour the recommended amount of fresh oil into the engine.
    • Check the oil level with the motorcycle in an upright position, and add more if necessary. Be sure not to overfill.
  8. Clean up and check for leaks:

    • Wipe off any spilled oil and ensure the drain plug and oil filter are securely tightened.
    • Start the engine and let it run for a few minutes, then check for any oil leaks around the drain plug and filter.
  9. Dispose of the used oil properly:

    • Place the used oil in a sealed container and take it to a recycling center or a designated oil disposal facility.

That's a general overview of the oil change process for a Harley Davidson 103 engine. Remember to consult your owner's manual for any model-specific instructions or variations.
