The engine in the 1985 Harley-Davidson FLH is vulnerable to hard particulate damage. A spin-on type oil filter cleans the engine oil as it circulates through the engine's lubrication system. Inside the filter, a pleated-paper element with steel mesh reinforcement removes metal salt, carbon flakes and other damaging particulates from the engine oil as it leaves the engine and returns to the oil tank and reservoir. Since the filter has no by-pass capability, it acts as a restriction in the oil circuit when clogged, causing significant disruption to normal oil flow. Properly maintain the oil and filter to prevent engine wear and damage.
Tools Used: Catch pan, Socket-stye oil-filter wrench, Lint-free shop rags, New oil filter, New engine oil
Change Oil Filter
Park the motorcycle on firm, level ground and rest it on the jiffy stand. Place the catch pan under the transmission area of the bike. Place a socket-style oil filter wrench over the filter as squarely as possible. Rotate the filter with the filter wrench counterclockwise to break it free from the filter base.
Unscrew the filter by hand and then quickly remove it from the bike. Once removed, oil will leak from the filter. Minimize the amount of oil that spills onto the crankcase cover. Drain the oil filter fully into the catch pan. Clean up spilled oil immediately with a clean shop rag.
Wipe the filter base with a clean, lint-free rag to remove grit and old oil.
Smear a thin layer of new engine oil onto the gasket of the new filter. Spin the new filter onto the filter base by hand with a clockwise rotation until the gasket contacts the filter base.Turn the filter in a clockwise direction an additional 1/2 to 3/4 of a turn by hand. Use a clean shop rag to augment your grip if the new filter is slippery.
Wipe the filter and surrounding areas with a clean shop rag to remove any remaining engine oil. Check and top off the engine oil level in the reservoir. Start the engine. Observe the filter. Ensure that there are no leaks around the oil filter and base.
Tips & Warnings
If performing the filter change in conjunction with an oil change, start with Step 3 after the old oil drains, and the oil drain plug and gasket are reinstalled and the plug tightened. The oil from the filter will drip onto the left crankcase half during removal. Quickly remove the filter to minimize spillage. Immediately wipe up spilled oil to prevent it from spreading beyond what you can easily clean. A full bike wash may be necessary in extreme cases to remove all of the spilled oil.
Discard the used engine oil at an approved hazardous waste facility. Use caution while performing this procedure as the engine parts, oil and exhaust pipes may be hot. Thoroughly wash your hands after contact with engine oil.
