Draining Oil Tank

WARNING

Be sure that no lubricants or fluids get on tires, wheels or brakes when changing fluid. Traction can be adversely affected, which could result in loss of control of the motorcycle and death or serious injury. (00047d)

NOTICE

Do not switch lubricant brands indiscriminately because some lubricants interact chemically when mixed. Use of inferior lubricants can damage the engine. (00184a)

Completely drain oil tank of used oil at scheduled service intervals. Refill with fresh oil. Refer to Maintenance Scheduling → Regular Service Intervals → Regular Service Intervals: 2015 Sportster Models .

NOTE

Change oil at specified intervals in normal service at warm or moderate temperatures.
Change engine oil at shorter intervals in cold weather or in severe operating conditions. See Maintenance and Lubrication → Winter Lubrication.
Change engine oil at shorter intervals if ridden extremely hard, used in competition or driven on dusty roads.
Always change oil filter when changing engine oil.

1.	Run motorcycle until engine is at normal operating temperature. NOTE To drain oil faster, remove the dipstick.
2.	Remove dipstick from oil tank. NOTE The drain pan must hold approximately 2.8 L (3.0 qt).
3.	Place a drain pan directly under the drain hose.
4.	See Figure 1. Pull drain hose clip (1) from frame tube.
5.	Direct hose (2) in front of the brake line bracket (3) into drain pan.
6.	Loosen worm drive clamp (4). Pull drain plug (5) from end of drain hose. NOTE Completely drain engine oil from oil tank.
7.	Allow oil to drain.
8.	Install drain plug into end of drain hose.
9.	Tighten worm drive clamp to 0.7–1.1 N·m (6–10 in-lbs).
10.	Route drain hose alongside frame tube.
11.	Clip hose to frame.

Removing Oil Filter

1.	Place a drain pan under the oil filter. NOTE See Figure 2. Turn oil filter (1) counterclockwise to remove from mount (2).
	NOTICE Use Harley-Davidson oil filter wrench for filter removal. This tool can prevent damage to crankshaft position sensor and/or sensor cable. (00192b)
2.	Remove oil filter using OIL FILTER WRENCH (Part Number:HD-42311) or OIL FILTER WRENCH (Part Number:HD-44067-A).
3.	Drain engine oil. Discard oil filter.
4.	Clean any oil spills off crankcase and frame.

Installing Oil Filter

NOTE

To build oil pressure on engine startup, partially fill oil filter.

Pour about 120 ml (4 fl oz) of fresh, clean engine oil into new oil filter.
Allow time for oil to soak into filter element.
See Figure 3. Wipe filter gasket contact surface (1) of oil filter mount with a clean cloth. Surface must be smooth and free of debris or old gasket material.
Apply a thin film of oil to contact surface of the oil filter mount and filter gasket (2) of new oil filter.

NOTE

Do not use oil filter wrench to install new oil filter.

Install new oil filter.
1. Screw filter onto adapter (3) until gasket contacts the gasket contact surface.
2. Hand tighten an extra 1/2-3/4 turn to secure the oil filter.

Refilling Oil Tank

NOTICE

Do not overfill oil. Doing so can result in oil carryover to the air cleaner leading to equipment damage and/or equipment malfunction. (00190b)

NOTE

Do not overfill the oil tank. Excess oil creates excessive pressure. To prevent damage, a pressure relief valve opens to release the excess oil.
Use the proper grade of oil for the lowest temperature expected before the next oil change. Refer to Maintenance and Lubrication → Engine Lubrication → Recommended Engine Oils .

Pour 1.9 L (2.0 qt) of oil into engine oil tank.
Install dipstick in oil tank. Seat cap.
See Figure 4. Verify oil pressure.
1. Start engine.
2. Verify that the oil pressure indicator turns off at 1000 rpm or above.
3. Turn off engine.
Perform engine oil level hot check.
Start engine and carefully check for oil leaks around drain plug and oil filter.
