Default Re: 4.11 and 3.78 pinion difference?

Wonderful. That's what I figured...

Even with all the paper shims installed, as the side bolts are tightened, the pinion gets progressively harder to turn, and feels sorta lumpy as it tightens up. Pretty sure it's not the bearings...

Never encountered this problem before.

Thanks for the tip too!

Hint on the preload: Don't mess with the KRW spring loaded gage, it's not nearly as accurate as you'd think it to be. A fast, easy, and really much more accurate method... Using a large bench vise, clamp the spline in the vise pointing down. Take the banjo in both hands and spin it hard and fast. When you have the preload right, it will make less than one complete turn and stop.
