The adjusting nut with all the teeth on it,,,

What tool can I purchase to adjust it properly?

 

I used a steel punch and just tapped it to turn it. I followed the procedure in the manual. You have to loosen the pinch bolts on one of the trees and the stem nut too, if I remember correctly. Then adjust the nut, tighten the trees, tighten the stem nut to torque spec, then check the fall away.

 

Same here but the tool would have made it easier!

 

if i recall correctly, you don't need to move that much to make difference

 

A hammer and a long-bladed screwdriver did it OK for me. Might be tricky trying to get another sort of tool in there.
