I swapped out the stock derby cover on my 2019 Road Glide Special for a Drag Specialties cover. Both have the slot for the knobby ring. After I installed the Drag cover, I noticed there there is a small seep at the bottom of the derby cover. I looked at the spare pancake gaskets I have for my two Twin Cam scoots but that gasket will not fit, too small. Does anybody know the correct PN for the full gasket? My local HD dealer is clueless. Thanks!

Thanks! That's the o-ring type, I'm looking for a pancake type. Not sure if anyone makes it.

 

Drag Specialties is the China parts store now days. Dang it.

 

Okay so I did some research and found a tip to fix this from another forum member. Per their instructions I pulled the derby cover, removed the o-ring gasket, and carefully cleaned/dried the inside of the cover and o-ring gasket, taking care not to stretch or pinch it. Also, if the o-ring gasket is a little too big and won't stay in the groove, put it in the freezer for a couple of minutes and it shrinks enough to fit. Don't leave it too long or you may crack it. Then I cleaned and dried the mating surface on the primary cover. The cover, gasket and mating surface must be dry. Put everything back together and torqued to 90 inch lbs. No leak, no seep. I'm still gonna keep looking for the pancake type gaskets though, IMHO they are easier to use and less hassle than the o-ring gaskets.
