If you stripped the plug itself then just replace it with a new one. If you stripped the housing, then you have two options, you could replace the housing or take it to an automotive engineer who will either weld and re-thread it or heli-coil it for you.

Where is the oil plug on 2008 harley nightster

Transmission/primary or engine????

Engine drain plug is in a rubber hose that hangs down under the motorcycle transmission area at about the point where the kickstand rests in it up position. It has a worm clamp that you would loosen with a one quarter inch socket to allow you to pull the plastic plug out to let the engine oil drain out. The transmission/primary drain plug is on the bottom of the primary cover right below the middle of the clutch inspection (derby) cover. It is a 5/8 inch hex head plug

Drain plug is at base of primary case and when you refill it you fill it through the clutch inspection cover (derby) and just until the oil reaches the bottom of the clutch diaphragm spring.

Recently bought a 2003 1200 sportster. Specifically asked the previous owner about shutting off petcock when not in use. He indicated it was not necessary as it had a carb drain feature. I've put...

Your 2003 Sportster should have been equipped with a vacuum operated petcock unless someone has changed it out. This is highly likely since the factory units were very prone to problems. To drain the primary, look for a pipe plug underneath the primary at the very back underneath the area of the clutch. Refill with one quart of H-D 20W50 SYN3 engine oil or any other suitable lubricant.

Good Luck

Looking for the oil drain plug and the transmission drain plug on a 2001 Harley Davidson XL 1200 Custom

Usually the oil drain is one the left side of the bike somewhere below the battery. Look for a hose that has a plug in it or one that connects to the frame. Harley had moved this drain so many times in the past that it's difficult to keep up with where the oil drain is located. The transmission and primary share the same oil. To drain it, find the drain plug on the bottom of the primary just below the clutch. Pour the new oil in the primary chain inspection hole of the primary.

Good Luck

Where is the oil drain plug on a 2006 harley davidson sportster

Usually it's a short piece of hose plugged onto a "stub" on the frame or a plugged hose on the left side of the bike just below the battery. It should have a funny looking hose clamp on it. This is for draining the oil tank. The primary drain is a small pipe plug underneath the primary back where the clutch is.

Level for primary oil required

Well, if depends on which model bike you're talking about, a Big Twin or a Sportster. On the Sportster, simply pour in a quart. Some Sportsters have an "oil level drain hole". A plug either on lower front part of the outer primary or on the rear end of the primary. Take the plug out, fill until oil just starts to run out and stop.

On the Big Twins, remove the derby cover, stand the bike straight up, and fill until the oil level just barely touches the lowest part of the clutch spring. The spring is a round spring that is usually darker in color than the surrounding aluminum clutch drum. Do not overfill as this will make your clutch drag and you will not be able to get your bike into neutral with the engine running. Depending on year and model the primary will take anywhere between 36-44 ounces of oil.

Good Luck

Does an 01 sportster 1200 have an oil bath. clutch.This persons tried to change his own oil pulled two different plugs one oil was clean one was was not. It has a hard time shifting now

Yes it does. It should take about a quart of oil in the primary. Some primary covers have an oil level indicator hole at the very back of the primary just bit above the lowest point. The drain plug is underneath the primary. If you have an "oil level plug", remove it and add oil until it comes out of the hole. If you can't find a level hole, drain the primary and refill with one quart of oil

I dont know how much oil i got stick in my 2005 harley sportster gear oil

On some of the late model Sportsters there is an oil level plug. Look on the rear of the primary cover for a small plug. There will be a plug at the bottom of the primary but that is the drain. The one I'm talking about, if your bike has one, is going to be up about two or three inches (50-75mm) from the bottom on the backside.

If your bike does not have the plug, you must pull the plate off the side of the primary cover where the clutch assembly is. Look at the clutch assembly and you'll see the flat spring in the assembly. The oil level should be just to the bottom of that spring with the bike standing straight up.

Good Luck

How to change transfer case oil

I assume that by the term "transfer case", you're talking about the primary drive and transmission on your Sportster. The lubricant that you pour into the primary case also lubes the transmission. Not so on a Big Twin as they each have their own lubricants.

On the Sporty, theres a drain plug on the bottom of the primary case near the rear end of it. I'm pretty sure it uses a Torx driver to remove it. Drain the oil and refill with H-D primary & trans lube for Sportsters. Remove the derby cover at the rear of the primary cover and fill the primary until the oil level is even with the clutch pressure spring with the bike standing straight up. Replace the derby cover.
