You will need either the HD oil filter wrench (HD-44067), which fits over the end of oil filter Harley-Davidson SuperPremium5 Oil Filter 63731-99A and allows you to remove filter with a ratchet and extension, or a strap type oil filter wrench purchased at an autoparts store. I use the strap type generic wrench. The HD wrench, actually a hex cap to fit over end of filter, would be a worthwhile investment. There is very very limited side access to filter on bike neccesitating one of these tools. Pan drain plug on same side, to front of pan at corner. Drain oil, remove filter, wipe off filter mount, fill new filter with fresh oil and install, pour in 5 quarts total using a flexible neck funnel, and your done. It takes 5 quarts total including what you use to fill new filter. SAE 20W50 or SAE 60 grade is appropriate for ambient temperatures above 80 deg to over 100 deg F. BE VERY CAREFUL WITH "O" RING !!!!!

This one is tricky get yourself a service manual. "O" rings are a pain man! train plug should be line up with dip stick.

Hmm, that's a good since I haven't seen a six speed up close yet. I work with the older bikes. But, one the five speed, the drain on the Softail was a small pipe plug that uses a Torx wrench. It is located just below the right side chrome cover where the clutch cable goes in. The drain will be there or underneath the tranny but more than likely where it has been on the five speed.

Good Luck

Where is the oil drain on the 2003 Heritage Softail Classic?

No expert on newer Hogs but try this.If tank is replica of wrap-around type look on flat right-rear bottom over rear pipe.Just a flat bolt-head.Yep,it's messy,cover the pipe.Like I said,no expert. Follow bottom most oil line from oil pump back to oil tank. Maybe it "t's" off under frame into line that drops down toward ground. You could get a catch pan under there.I vote for the nut on tank.Wrap around,you know, the battery is in it.

Harley davidson flstc heritage softail 1997

The fork oil is a very specific job needing a manual and a special tool, I don't want to insult anyones mechanical knowledge but if you have never done it before, best to take somewhere else. Engine oil on the other hand is easy, the drain tube to any softail is on the right side by where the frame meets the swing arm, has somekind of plug in it. Start and run bike for a little while, long enough to get it warm but not hot. Remove fill plug and then remove plug in drain line. Using a peice of cardboard or something put in between filter and frame , directing the oil to your drain pan instead of where ever it goes. Put 1 qt oil back in (after everything is reinstalled) start the bike and make sure the oil light goes out, when it does shut bike off and fill to the point that when it is standing upright you get a little oil on the tip of your finger, over filling may result in loss of oil cap from pressure (been there)
