I had a custom derby cover engraved for my bike. The designer used HD Part Number 60769-06. I know there are at least of models of derby covers that will fit, but use different gaskets. I'm going to swing by a dealership to pick up some chrome screws, can anyone tell me what gasket to get to properly install that derby cover to my '12 Glide? I presume I will need a new gasket, and not just re-use the one that's there.

Thanks in advance (yes, I will post pictures, the thread would be worthless without it).

 

OEM derby cover uses o-ring style, all aftermarket ones use the pancake style.

I looked for that part number on hd.com, not found.

If it uses the o-ring style, it will be easy to tell, there will be a slot for it that runs around the perimeter, if there isnt a slot, it uses the pancake style

 

That's strange. My last oil change the dealer sold me the pancake. When I took the derby off I had the o-ring. I had to use the pancake because when I took the o-ring off to wipe it, it wouldn't fit back in. The o-ring was too big.

 

Most likely you will need the flat gasket part number 25416-99C. The easiest way to tell is if the mounting surface is flat or if it is cut with a groove for the o-ring.

 

You arent supposed to re-use the o-ring.

 

Some Harley part derby covers use the pancake gasket too. Just not the covers from the factory.

 

I've seen many posts here saying that you can reuse the o-ring. If I'm not mistaken, even Fix My Hog DVD's say you can reuse it. Hmmm....

 

72500 on mine and on my 2nd gasket because they took it under warranty...

 

If you have an o-ring (or quad ring, or whatever you want to call it) groove in either the cover or the primary case itself, then use the o-ring. If not, then use the gasket.

The ring stretches with use, but you can usually work it into place with a little persuasion and patience.

I have one bike with 80,000 miles and another with 33,000, both with 5,000 mile change intervals, and I have never replaced the original o-ring on either of them.

 

Yeah, I'm sure its fine to re-use, I just figure for a few bucks get a new one and help support your local HD owner's college fund.
