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!
The RK oil tank is on the bottom of the transmission. the drain plug is near the center of the oil tank. There is also a transmission drain on the side of the oil pan. Loosen the plug just enough to allow a little oil out to make sure you have the correct plug before you take it completely out. It take three quarts of oil with a filter change.
Since I don't work on the later model bikes, I'm not certain when Harley changed the location of the transmission drain plug. On your model, there should be a drain plug on the bottom of the transmission. If not, it's a small pipe plug located just below the chrome end cover of the transmission behind the exhaust pipes. The difficulty in getting to the plug when it's located on the side of the transmission is one of the reasons Harley moved the drain plug to the bottom of the transmission. Drain the oil and then remove the large plug from the chrome end cap on the right side of the transmission to refill it. The plug takes a large Hex key or Allen wrench to remove it, 3/8" on the earlier models. Fill the transmission with 20-24 ounces of transmission lubricant or H-D Syn3 20W50 synthetic engine oil.
I'm not a Twin Cam mechanic but I think there are two oil drains on the bottom of the transmission. The oil tank for your bike is on the bottom of the transmission. It looks like there is a drain on the bottom of the pan and one on the front. The oil should be changed every 3000 miles if you're using petroleum based oil. Synthetic oil can go a bit longer. The primary oil and transmission oil should be changed every 5000 miles or so. The primary drains from a pipe plug underneath the primary back near the rear of gearcase. The transmission drains from a plug underneath.
In my first attempt to change my engine oil, I drained oil from bottom of my 2001 Fatboy, from the plug on the right side towards the front of the engine, just below the Twin Cam Cover and floor board (see attached picture) look at dark spot where plug is located, only approx 4 oz drained out, where is this from? How to I refill that oil?
P.S. I did find the right one mounted on the right side towards the rear of the engine, so oil is now changed.
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.
There are three areas that you have to service, engine oil, primary oil, and transmission.
To change the engine oil, underneath the transmission, you'll find two drain plugs. The drain plug nearest the left side of the engine is the the engine oil drain. Warm the engine a bit and drain the oil. Change the oil filter. This is a messy job so put something down to catch the oil as it runs out of the filter. Replace drain plug and refill with oil.
The plug nearest the center of the transmission is the transmission drain. Remove the plug to drain the transmission. Once drained replace the plug and refill the transmission through the transmission fill hole in the chrome cover on the right side of the transmission.
To change the primary oil, underneath the primary outer cover very near the rear of this cover is a small drain plug. It takes a Torx wrench to get the plug out. Remove the plug to drain the oil from the primary. Remove the derby cover over the clutch. Refill with oil through the derby cover hole.
Your bike probably came with H-D Syn3 oil. You can replace the oil with this or any other oil as long as it carries a rating for use in a diesel engine. Here, it must have an API code of "C", example "SJ/CG4". Four quarts of engine oil, Add three quarts of oil and check. Fill to proper level with the fourth. Your dipstick is marked with a "Full Cold" and "Full Hot" mark. Fill to "Full Cold" mark and check again after warming up the engine.
Use Syn3 in the primary or 30 weight oil, 40-44 ounces. With the bike standing nearly straight up, the fluid level should be to the bottom of the clutch spring, large black disc in the center of the clutch. It's a diaphragm type spring.
Use Syn3 in the transmission, 20-24 fluid ounces. Check with the dip stick again with the bike standing straight up.
The plug ( 3/4 wrench ) under the trans when your looking at the trans cover ( right side of the bike ) is the trans. If you drained that replace it with 24 oz. of either HD trans fluid or I prefer Golden Spectro 75/140 ( much better shifting on a Harley ( trust me you'll never go back to HD trans fluid ) the drain for your motor oils is on the same pan ( on the bottom ) but it's the plug facing the front of the bike. Looks just like the trans plug. Both use a 11105 o ring which you should replace everytime ( just for piece of mind as well as leaks ) you need 4 quarts of 20/59 HD oil. Hope it helps.
