There is a allen head plug on the bottom of the engine on the right side, but this is only for the residual oil not pumped back into the tank. The easiest way to drain the oil tank on a softtail is to diconect the lower feed hose either from the engine side or the tank side. If Harley was the last to do an oil change you will have the crimped on type hose clamps so you will have to get a replacement standerd hose clamp. I personally prefer to disconect the hose at the engine end so that I can direct most of the oil away from the bike.

Stand the bike upright. Remove the dipstick from the oil tank. Remove the drain plug on the bottom right side of the frame. While the oil is draining, replace the oring on the drain plug. Remove and replace the oil filter, after filling the new filter half full of oil. Replace the drain plug. Put 3 quarts of oil in the oil tank. Replace the dipstick. Start the bike and check for leaks. No leaks, you're done! I use HD Syn 3 synthetic oil in my '04 Fatboy, but you can also use a conventional 20w50, as long as it's made for use in and air cooled motorcycle. Don't use car oil!
Hi Chanceycoalm, you drained the transmission, replace oil with 20-24 oz. HD Transmission Lubricant. The engine oil drain plug is on the bottom of the frame tube right hand side all the way in the rear. Have nice day.
the drain plug to drain the oil is on the frameit is on the left side,look on the bottom of the frame by the swingarm and the frame you will see a 5/8 bolt with a allen in the middle.never take the ones out of the motor.
From the right side of your bike, look under the oil tank and find a hose or pipe running downwards towards the transmission. Follow this all the way down to the lowest part of the frame just behind and to the rear of the transmisson behind the exhaust pipe. There will be a plug in the hose or pipe. Remove this plug to drain the oil tank.
So I checked another Harley maintenance book of mine, and it says "On
pre-2000 Softails, the drain is on the right side of the tranny near the
dipstick. On the 2000 and later Softails, the drain is located on the
bottom between the two shock absorbers. The drain plug on Dynas and FLs
is located on the bottom of the transmission case next to the oil
I got this from another site, I was going to say, it might not be on the bottom, but I found this, seems nobody can find it. Hope this helps.
on the oil tank there should be a drain hose that goes down and hitches to the frame on the bottom of the frame there should be a drain bolt. That is your engine oil drain plug and should be on the right side
On the fatboy, the oil drain plug should be on the right side, just under the frame, directly below the oil tank. The primary drain is on the left side under the derby cover on the bottom. The tranny drain is on the bottom towards the rear pretty much centered. And, as our darlin' little miss piglet said, a maual is worth the investment.
Fatboy, drains from the oil tank bottom right side rubber tube goes down to frame, bolt in frame is plug. Have to get to it from underneath. This is only engine oil. After oil change three quarts, if change filter 3.5 quarts.
Hope this helps.
