If you use the information in this video to service your own bike, you will save $300 to $500 each time you service your Harley as compared to expensive dealership service fees.

In this video i cover the procedure i use to drain and replace the engine oil, transmission gear fluid, and primary fluid as well as the process to remove and install a new engine oil filter. I show the drain plug locations and the fluid fill and dipstick locations.

Always remember, to start your bike and let it run for at least 5 minutes before you change the oil. Warm oil drains better, pulls out sediment better, and with "Dry Sump" engines like in our Harley Davidson motorcycles, the oil tends to "sump" down into the engine case over time which will prevent you from draining all the oil from the bike during this procedure. This creates a problem because when you start the engine after a cold oil change, the oil pump will pump all the oil that has settled into your engine cases back up into the already full oil tank, causing it to overflow all over your bike and floor and driveway.

This process will be basically the same for all Harley Davidson Iron head Sportster motorcycles built from 1957 to 1978 and can be used as a reference for 1979 to 1985 Sportsters also.
