Can you oil/grease a QR skewer cam
 

I think I read emphatic no but I can't find it now.

I have one that I can't get to close all the way when it's tightened across the fork about right. The lever moves freely when the skewer's removed. But on the bike, the lever goes just past the tightest part of the cam then stops. I can push on the lever so it seems tight, but it doesn't go as far as it should, and when I open the lever it gives way with a sharp pop.

Maybe corrosion on the cam? Or maybe I did something to damage it.

This is the kind where the lever is peened on so you can't open it to look at the cam.

I swapped a different skewer onto the bike for now.

To answer your question about the grease/oil, I've put a drop of oil inside QR cams before. I've not any problems with doing that but I suppose there could be some concern about the oil damaging any rubber materials in the QR.

As for your QR, it could be damaged and in need of replacement.

I always keep my QR cams lubed with heavy oil.

Whenever I do a rebuild, they always get oiled.

As others said, yes. This is a standard (although minor) step on the tune ups I do. Andy

I too put just a touch of something in there just to keep them from possibly getting corroded or worse. Jon Cannings said it was ok in a video eons ago, that's good enough for me.

Oil it is then. Thanks you all.

Oil (Phil's Tenacious) has resurrected the ailing skewer. Thanks again.
