Steps to Change Primary Oil

To change the primary oil in your Harley Softail, follow these steps:

  1. Start by draining the old oil from the system.
  2. Next, replace the oil filter with a new one to guarantee peak performance.
  3. Finally, fill the primary with fresh oil to keep your bike running smoothly.

Drain Primary Oil

Before starting the process to change the primary oil in your Harley Softail, make certain you have the necessary tools and a suitable workspace prepared.

To drain the primary oil, place a drain pan under the primary case and locate the drain plug at the bottom of the primary housing. Using an appropriate wrench, loosen the drain plug to allow the oil to flow out. Make certain to have a rag handy to wipe off any excess oil that may spill.

Once the oil has completely drained, inspect the drain plug for any metal shavings or debris, which could indicate an issue that needs further attention. Clean the drain plug and verify the O-ring is in good condition before reinserting it securely back into place. Tighten the drain plug to the manufacturer's recommended torque specification to prevent leaks.

Properly disposing of the old oil is essential for environmental safety. You can take the used oil to a local recycling center or an auto parts store that accepts oil for disposal.

Replace Oil Filter

First, locate the oil filter on your Harley Softail to begin the process of changing the primary oil. The oil filter is typically positioned on the left side of the engine. Using an oil filter wrench, carefully loosen the filter in a counterclockwise direction. Be cautious as some oil may still be inside the filter. Once the filter is loose, remove it completely by hand.

Next, it's important to clean the filter mounting surface on the engine. Wipe away any residual oil or debris using a clean rag. Inspect the rubber gasket on the new oil filter to make sure it's in good condition. Apply a thin layer of fresh oil to the gasket to help with sealing.

Now, install the new oil filter by turning it in a clockwise direction until it's snug. Avoid over-tightening, as this could damage the filter or the mounting surface. Double-check the filter to make sure it's securely in place.

This completes the step of replacing the oil filter in your Harley Softail as part of the primary oil change process.

Fill With New Oil

Once the oil filter is firmly replaced, proceed to fill the engine with new oil as part of the primary oil change process. To start, locate the oil fill cap, typically found on the primary cover. Unscrew the cap and set it aside.

Using a funnel for precision, slowly pour the recommended amount of primary oil into the oil fill opening. Refer to your Harley Softail owner's manual to confirm the correct oil capacity for your specific model.

After pouring in the new oil, carefully replace the oil fill cap and make sure it's tightly secured. Next, start the engine and let it run for a few minutes to allow the oil to circulate throughout the primary system. Once the engine has run for a brief period, turn it off and give the oil a few moments to settle.

After the oil has settled, check the oil level using the dipstick or sight glass, depending on your Harley Softail model. Top off the oil if needed, making sure not to overfill.

Factors Affecting Oil Quantity

Factors like engine size, design, and operating conditions can significantly influence the amount of oil needed in the Harley Softail primary.
