The oil drain plug is at the bottom of the oil tank (for engine). Bottom rear of primary case for primary & transmission.
The 82 had the plug on the bottom of the oil tank. No plug on cases.
Check out the pictures at the following website. The drain plug is toward the rear of the bike, in front of the rear tire. http://www.harleydavidsonmaintenance.com/sportster-oil-change.html
There is no transmission drain plug. Your transmission uses the same oil from the primary. Draining your primary drains your transmission.
That plug is the drain plug for the primary and transmission oil supply.
There is a rubber line that attaches to the bottom of the oil bag. Pull that line and the oil will drain
My Sportster has a drain hose that attaches to the oil tank and crosses over to the opposite side of the bike. It is hose clamped to something like a lug on the bottom of the bike frame.
YOU drain the engine oil from the rubber tube just under the battery tray. THERE is a plug built into the underside of the tray. ....Have a few rags under the bike ...this can get MESSY. Alan
on bottom of trans. case. kind of hard to reach
The oil drain plug on a 1987 Harley Davidson Sportster is located on the bottom of the engine's oil pan, typically towards the rear of the bike. It is a hex or socket head bolt that can be accessed from beneath the motorcycle. Make sure to place a drain pan underneath to catch the oil when you remove the plug for an oil change. Always refer to the owner's manual for specific details and torque specifications.
it's a hose coming from the oil tank....take it off the end connected to the frame, drain the tank and clamp it back in place.
there is no need for an engine oil drain plug, because when the oil filter is removed and the oil is drained from the oil tank (by way of the oil tank drain hose located by/under the battery box) there is no oil that remains in the engine.
theres 2 hoses coming out of oil tank on bottom...One goes to the oil pump other one clamps on to frame. Take clamp off and drain the hose...That will drain the oil
