Where is the drain plug/ tube on a 2003 Harley Davidson softail standard for changing oil?

I am going to change the oil on my softail and just want to know were to drain the oil from on the crank case!Where is the drain plug/ tube on a 2003 Harley Davidson softail standard for changing oil?
No,.. there is only one engine oil drain plug. Its on the frame on the lower right in front of the swingarm on the transmission trap door side. Its a tube that drains the oil tank. what little is actually in the crankcase is very minimal.


The other drain plug the other poster described is the PRIMARY case drain. The primary should be changed at the same time as the oil, and unless you are using something special it takes the same oil the motor takes. The primary is refilled at the small oval inspection cover w/ 4bolts. Takes 1 quart, and its assumed that during this service the primary chain is adjusted (tightened) while you have this cover off....or if you are adjusting the clutch simply pour it in the derby cover hole.Where is the drain plug/ tube on a 2003 Harley Davidson softail standard for changing oil?
There are two, one one the left of motor down on right side of primary cover( not much oil will come out). The second one is a drain hose coming off oil tank on right side of bike, just in front of the swing arm on top side of the bottom of frame. Be sure to take off oil tank and clean with kerosene, you are to flush oil tank every other time you change the oil.
Polar bear has some of it right. You do not have to change primary oil every time you change engine oil and, unless you are using the new synthetic oil, there are 3 different kinds of oil, Engine oil, tranny oil, and primary oil. Those 3 oils can only be used in their stated component. Tranny oil in the tranny and so forth. BTW, DO NOT remove the oil tank.
Well to be fair to Gina some Harleys most certainly do have an oil pan under the transmission.But Polarbear does have it right for the Softail model.And like he said there is no crankcase drain plug on factory cases.Gina i'll give you a thumbs up for trying.You just had the wrong model Harley.
Find your oil pan, underneath there will be a drain plug nut, be careful to not lose the small rubber seal when you remove it.
lol gina wasn't even close oil pan ? on a harley? lmfao polar bear has it all correct
Well Gina, you tried... kudos to you... but polarbear has it bang on
