Where is the primery drive oil drain bolt - 2003 Harley Davidson FLSTC Heritage Classic

Final drive assemblies on motorcycles generally cost over $1000. They tend to show signs of dirt after only 5000 miles. Having driven shaft drive motor cycles for over 30 years I usually change my 85/90 Hypoid gear oil at every second engine oil change. It is never very dirty but if taken into the sun light will show some fine metal chips (nothing to worry about). I highly recommend using synthetic Hypoid gear oil. It will cause less friction and the final drive will run at a much cooler temperature. One quart of Hypoid gear oil will change the rear end oil 3 or 4 times so it is good, cheap preventive maintenance. Simply take off the large fill cap, place a pan under the small drain bolt at the bottom of the pan,remove the drain bolt, drain the oil, put the drain bolt back in, and fill the final drive to the bottom of the larger fill hole (usually a quarter to half cup of oil), then replace the large cap being careful to only snug it tight enough to seal in the oil. If you over tighten it, it is designed to break! Be sure to check the owners manual on the exact amount of oil to use. Honda has changed the fill technique for some of the newer models. With a higher fill hole on some newer models you may be over filling the final drive, so you may have to measure the amount. Too much oil will cause waste and may cause over flow out the top vent. Happy Trails.

Remove the drain plug at the bottom of the rear hub ( have oil pan ready in place so oil doesn't drip on back tire. Remove the bolt on the side of that hub unit then replace the drain plug. Fill the hub unit with a hypoid gear oil (80w90) to the top of bolt hole. Then replace bolt. Do this every 3000 miles.

Could be the gasket for the whole oil pan that's leaking. That would let oil run down the oil pan, to where the drain plug is.

there are 2 possibilities

Yes, you need to change the rear gear oil.
Back of the bike where axle runs through left crankcase. There is a small 10mm bolt on the bottom.
Take that out and the gear oil will drain. This is the drain bolt.
When empty replace the drain bolt and remove the fill bolt/cap 10mm on the side of the left crankcase. Should be approx 2 inches above the drain bolt. It will be marked right on the case.
Fill it up with gear oil until it runs out the hole your putting it into.
Screw the cap/bolt back in and your good to go.

Yes, your drive belt is breaking,tearing. Located on the left side of engine under clutch cover.

You do not put oil in the recoil housing, the drain bolt is for draining water that gets in there if you drive through water. The oil you seen could have been put in there to lube the moving parts when it was apart at a an eariler time.The bolt at the top is to to do a visual inspection for.

The device at 12 0'clock is a breather. Check you have the right amount of the right grade oil in the final drive. Best to drain it all out and start again.
