I knew once I saw the oring, broken, that if I went to Harley they would charge me too much for just one.

So I went to Lowes and got 10 of them for under $2.00. Many miles later and a couple days sittin there while I was working and no leaks.

I just took the old one in and matched it up to the ones they had in plumbing.

 

Thanks for the tip. Cuz I'm cheap hehe.
Just take ur dremel out and engrave Harley davidson on it and your good to go. Lol

 

Exactly what I have done with LOTS of parts on my bike. Stuff that can come from the hardware/auto parts store go on. The dealer charges a premium for their name. That's all.

 

Ace Hardware is also a good place for fasteners and O-rings, etc..

 

agree on the oil filter. I believe its a 30micron filter for proper flow.

 

You are correct. You have to be careful buying those K&N/Fram/Wix filters because they are not 30 micron.

Bumping this old thread. Haven't changed the oil on mine yet, so don't know what o-rings and gaskets are used. But I just got some parts from J&P, and I got the 5/8" coppergaskets, but now I'm starting to wonder if it's the wrong gasket?

Is this gonna fit, or do I have to get some rubber o-rings?

On the primary drain plug, there is a rubber o-ring on it. That washer you posted isn't necessary. You don't necessarily need to replace the o-rings and rubber gaskets every time you take it off/out. If its not leaking, I'm not going to mess with it.

 

Yeah, but the copper washer is supposed to replace the o-ring, right?

 

On what bike?
