Hi,what's with the rubber drain plug o-rings,does everyone else have the same problems with them splitting at every oil change?Is there a better one available that stands up to at least one oil change without breaking?

 

The part number for the O ring is 11105, order one to go with every oil filter. The same O ring for the transmission drain plug.

The transmission dip stick O ring is part number 11132


The Primary drain plug O ring is part number 11324

 

I've reused mine 2 times with no problem. Plus I ordered a bag of 20 of them when I bought fliters and primary gasket kits from Zanotti's. That way I won't find myself driving 20 miles to but one o-ring. I think they were $.17 each.

 

Maybe your tighting them down too tight . I get about two to three changes before they start to look worn, then I change them. But they are cheap enough to change out everytime. I don`t know if that helped any ?

 

are you seating them dry?
The o ring should have a little oil on it like the filter gasket.
make sure you torque the plugs so they are not too tight.

I've used mine twice on the oil bag drain...I guess taht makes three actually...factory in, and I've changed oil twice.

 

Thanks for the suggestions,this was my first oil change and yes I did seat the o-ring dry,but the one that was on there was split too from the dealers oil change. I'll put some oil on the ring next time and see if that helps.

 

lets see...15 oil changes so far and still the same rings

 

I'm sort of glad to hear someone else is having problems with the o-ring splitting. I can use a new o-ring every time and as I lube it and screw it in the o-ring bulges out and gets damaged. It's frustrating. The plug will not be tight if the o-ring is pinched. I have used a slightly smaller auto air conditioning o-ring but can't tell you the part number or size. You might take a new ring to an auto parts counter and see if you can match up with a better one. I believe they didn't machine the hole in the pan just right (Why, oh why am I not suprised?) One of these times I am going to use a counter sink bit or a large drill bit to relieve the sharp edge of the hole in the pan. I've had some luck wrapping a bit of teflon tape tightly around the o-ring. Believe me, I cuss H-D everytime I change oil!

 

I have 27,000 change every 3,000 that's 9 services and still the original rings. What am I doing wrong?

 

Hello Sleepneagle - Mine has 36k miles and its been a problem every 3k miles along with trying to get that oil filter off. Finally I discovered K&N filters with the 17mm nut made into the top of the can. I just reuse the old ring damaged or not with teflon tape tightly wrapped around it. I thought I had the only bike with this problem until now. Maybe someone forgot to do some final machining step on the plug or the hole it goes into. Next time its out I will try to fix it. I think if I relieve the edge of the hole in the pan it might allow the ring to go inside instead of bulging out. A copper washer would work instead of teflon tape and the ring I think.
