Can not find the oil drain plug on my 2005 softail I drained the trann fluid thanks for any help you can give me ROY

Look at the oil tank on your bike from the right side. At the bottom rear corner on the backside, you'll see a large diameter hose that comes out and goes down behind the transmission. Follow the hose all the way down behind the exhaust pipes and you'll see that it plugs onto a crossmember in the frame. Feel on the bottom side of this crossmember and you'll feel the drain plug. It screws into the crossmember from underneath it. Remove the plug and your oil tank drains. Refill with three quarts of 20W50 oil . Your transmission holds 20-24 ounces of oil.

Good Luck

Where is the drain plug located on a 2007 Harley Davidson Heritage Classic.

Looking under the bike up at the motor you'll see 2 drain plugs, 1 is motor and 1 is transmission.
Its easy to determine which is which because the transmission plug is vertical and the motor is horizontal.
Also you can drain the oil tank from the oil tank drain line which is plugged by a nipple on the frame. On the kickstand side of the bike, behind transmission.

How can i tell which is the engine oil plug and which is the transmission drain plug?

The oil drain plug is usually closer to the left side of the bike. But, you can loosen the plug and wiggle it just a bit to allow just a few drops of oil to come out. Engine oil will be dark colored. Transmission oil will be very clear. That drain is usually more in the center of the bike.

Good Luck

Want to change the oil and filter on my 1999 flstc

The oil drain is a large diameter hose with a metal plug in it. It runs down along the backside of the frame just behind the transmission on the right hand side of the bike. There is a metal clip welded onto the frame to hold the hose. Take the hose out of the clip, remove the plug, and drain the oil tank. Refill with three quarts of oil

The transmission drain is a small 1/8" pipe plug that takes a Torx wrench to remove. It is located on the right side of the transmisson just below the chrome clutch release cover. The tranny takes 20-24 ounces of H-D trans lube or Syn3 oil. The transmission fills through the large hole in the top of the chrome clutch release cover. It takes a 7/16" hex key to remove the plug, It has a dipstick on the plug.

2005 harley fatboy 96ci, primary housing drain plug stripped out, keeps turning in housing assy?

If you can turn the plug out, you can go to a large size plug. If you can't get the plug to come out, take the outer primary cover off allowing the oil to drain out as you remove the outer cover. Sure it's messy but you've got no choice. Now with the cover off, push down on the plug while trying to turn it out. It'll probably come out doing this. Then measure it and get the next size bigger. Tap the hole to the bigger size and install new plug. Good Luck!
