Oil drain plug location on a 1989 Sportster 883

Harley has changed the location of the oil drain on Sportsters so many times it's hard to keep up with. Look on the left hand side down low on the frame behind the primary. The hose simply plugs onto a stub on the frame.

Good Luck

Yes the primary case-transmission require it's own oil as the lubricant for this area is not provided by the engine oil. There is a drain plug located at the lower point of the case. Remove the plug and drain any oil that may be in the primary case. When finished, add one quart of oil to the case through the access hole at the top of the primary case where you check the tension on the primary chain.

Look on the left side of the bike just below the battery. You'll see a hose that either has a plug in it or one that is plugged onto the frame. Take this hose lose and the oil will drain. Refill with three quarts of 20W50 oil that meets H-D specs.

The exact location of the oil drain on a Sportster depends on the year model. But, in general, the oil drain is a hose that is plugged onto the frame or a hose with a plug in it on the left side of the bike. It is somewhere, depending on year, between the bottom of the battery tray and bottom of the frame behind the rearmost end of the primary cover.

Look on the left side of the bike below the battery box. They've changed them over the years but you'll see a large diameter hose that either has a plug in it or it is simply plugged onto the frame. If you pull the hose off the frame, be ready with something to catch the oil with.

Yes, there is oil in primary and transmission of your Sporty. To drain the oil, look for the drain plug on bottom of rear section of the primary area, back near the large round section of the primary. Drain the oil here and replace the plug. Add the oil at the top primary chain inspection port, large plug with a large "screwdriver" slot or two small bolts in it. Add 32-36 ounces of H-D "primary lubricant for Sportsters".

look on the left side of the bike back underneath the battery. You'll find a large diameter hose back there with either a plug in it or the hose connects to the frame. It will have one of those spring type hose clamps on it. Take this hose off and drain the oil out of the tank.
