I have been slowly ordering the updated clutch drum kits and clutches for my 034/036's with the larger bearing and larger springs and wider shoes. I ordered the clutch and rim kit for the last one about 2 weeks ago and everything finally arrived. I pulled everything out and opened the packages to do the swap and I found the bell end of the drum weirdly uneven, it does not appear to be ground on by anything. I do feel a bit vibrations if I spin it fast by hand but that could be from the bearing riding on a pen body, Im worried it could damage the oiler or the oiler key that it drives. Should I send it back and try again? The guy I got it from was off ebay, he has sold me tons of stuff over the years.
