Changing the Oil

Changing the oil on your Harley Davidson 103 engine is essential for maintaining its performance. Follow these steps to ensure a smooth oil change process.

Draining the Old Oil

1. Warm Up the Engine: Run the engine for a few minutes to warm up the oil. Warm oil drains faster.
2. Position the Motorcycle: Place the bike on a level surface using a center stand or motorcycle jack.
3. Remove the Drain Plug: Locate the oil drain plug underneath the engine. Use a socket wrench to loosen it and allow the old oil to drain into an oil pan.
4. Dispose of Old Oil: Once the oil fully drains, replace the drain plug, ensuring it’s tight. Dispose of the old oil at a recycling center.

Replacing the Oil Filter

1. Locate the Oil Filter: Find the oil filter, typically located near the engine.
2. Use an Oil Filter Wrench: Loosen the old oil filter with an oil filter wrench. Expect some oil to spill out, so keep the oil pan underneath.
3. Prepare the New Filter: Before installing the new filter, apply a small amount of fresh oil to the rubber gasket on the new filter. This ensures a proper seal.
4. Install the New Filter: Screw the new filter onto the engine by hand. Tighten it until snug, avoiding over-tightening.

1. Choose the Right Oil: Your 103 engine typically requires 20W-50 synthetic oil. Check your owner’s manual for specific recommendations.
2. Remove the Oil Fill Cap: Locate the oil fill cap on top of the engine and remove it.
3. Pour New Oil: Use a funnel to pour the new oil into the engine. Typically, the engine takes about 4 quarts of oil.
4. Check Oil Level: After adding oil, wait a moment, replace the oil fill cap, and start the engine. Let it run for a minute, then check the oil level using the dipstick. Add more oil if necessary.

Following these steps will help you successfully change the oil on your Harley Davidson 103 engine. Regular oil changes keep your motorcycle running smoothly and efficiently.

Post-Change Maintenance

After completing the oil change, focus on essential maintenance tasks to keep your Harley Davidson 103 engine running smoothly. Checking oil levels and proper disposal of old oil play significant roles in post-change maintenance.

Checking Oil Levels

Checking oil levels ensures your engine has the proper amount of oil for optimal performance. Allow the engine to run for a minute, letting the new oil circulate. Turn off the engine and allow it to sit for a couple of minutes. Then, pull the dipstick from the oil reservoir, wipe it clean, and reinsert it completely. Remove it again and inspect the oil level; it should fall within the marked range. If it’s low, add the recommended oil to reach the proper level. Always refer to your owner’s manual for specific oil capacity and type.

Proper Disposal of Old Oil

Responsible disposal of old oil protects the environment and complies with local regulations. Never pour old oil down drains or throw it in the trash. Instead, collect the used oil in a sealed container. Many auto parts stores and recycling centers accept used motor oil for recycling. Check for local disposal facilities or events in your area to ensure safe and eco-friendly disposal.

Conclusion

Changing the oil on your Harley Davidson 103 engine can be a rewarding experience. Not only do you save money but you also take pride in maintaining your ride yourself. By following the steps outlined and sticking to the recommended practices you can keep your engine running at its best.
