Check Clearance
Run a feeler gauge all the way around in the gap.
Clearance should be between 0.3 and 0.5 mm.
0.3 mm should pass all around the gap.
If the clearance is not between the given values, use shims to adjust clearance until it does.
Shims are available in the following dimensions:
^ 0.2 mm
^ 0.3 mm
^ 1.0 mm
