Step 6 — Replace shaft hex nut. Torque to
25-30
ft. lbs.
Step 7 - Check air gap with feeler gauge
(No.
32437) to .016" to
.031".
If air gap is not
consistent around the circumference, lightly pry up
at the minimum variations. Lightly tap down at
points of maximum variation. Fig. 82
Note:

The air gap is determined by the spacer shims.
When re-installing or installing a new clutch
assembly, try the original shims first. When
installing a new clutch onto a compressor that
previously did not have a clutch, use .040, .020,
and .005 shims from the clutch accessory sack.
If the air gap does not meet the specification in
Step 7, add or subtract shims by repeating Steps 5
and 6.
