I just noticed my top gear case on the steering column it is loose to when I get the set screw to line up
I put a shim washer under the cap but on top of the center gear shaft all is tight but I may replace with a thinner shim washer as I feel a tad of drag or should I let it wear in or an I way off base
I would have tried to find a thinner shim. You can put it together without the shim until you find the "right" one. Better a little loose than too tight..
Some folks drill and tap a new hole. Even some of the originalists do this.
I do what Steve recommended. You need a strap wrench or a heavy piece of leather to put around the knurled top while tightening. Be sure to use the correct size drill when drilling the new hole, and put tape around the drill bit so you don't go too far. As I recall the screw is a 6-32. Then tap your new hole. Next, the new 6-32 screws have too big of a head, and you need to turn it down to the original size.
