7. Inspect the friction surface on the clutch hub
and the friction surface on the pulley. Scoring
on the friction surfaces is normal. DO NOT
replace these components for this condition
only.
Inspect the steel friction surface on the clutch
and ensure that it is not damaged by excessive
heat. Inspect the other components near the
clutch for damage due to heat. If signs of exces-
sive heat are evident, it may be necessary to
replace the compressor. Excessive heat may
cause leakage in the seals and damage to inter-
nal components as well as external components.

9. Pry the absorbent sleeve retainer from the neck
of the compressor, and remove the sleeve.
10. Install pulley puller (1, Figure 4-23) and puller
pilot (3) onto the compressor, as shown. If a
multiple groove pulley is used, install puller legs
(J-24092) onto the puller in place of the stan-
dard legs. Extend the puller legs to the back
side of the pulley. DO NOT use the belt grooves
to pull the pulley from the compressor.
