Check air gap
with
feeler gauge. The
specifi-
cation
is 0.406-0.787 mm (0.016-0.031
inch).
If air
gap is not consistent around the circumference,
lightly
pry up at the
minimum
variations (Fig. 13).
Lightly
tap down at points of
maximum
variation.
The
air gap is determined by the spacer shims.
When
installing the original or a new clutch as-
sembly, try the original shims first. When install-
ing a new clutch
onto
a compressor that
previously did not have a clutch, use 0.040, 0.020,
and
0.005
shims from the clutch accessory sack.

If the air gap
does
not meet the specification
given,
add or subtract shims as required.
