Disassemble compressor (33, Figure 2-1-7) as necessary to replace worn, damaged, or defective
components:
(1)
Hold drive plate (88) from turning and remove capscrew (87) from compressor (33).
(2)
Using suitable puller, remove drive plate (88) and shim(s) (89) from compressor (33).
(3)
Remove snap ring (90) and cover (91) from shaft of compressor (33).
CAUTION
To prevent damage to pulley, ensure claws of bearing puller are hooked into
the top groove of the pulley, not under the grooves.
(4)
Using standard gear puller, remove pulley (92) from compressor (33).
(5)
Remove electrical lead for coil (94) from holder on compressor (33), then remove screws (93), and
coil (94) from compressor.
d.
(1)
Install coil (94) on compressor (33) with screws (93).
(2)
Install electrical lead for coil (94) in holder on compressor (33).
(3)
Using hand press, install pulley (92) onto shaft of compressor (33).
(4)
Install cover (91) and snap ring (90) on shaft of compressor (33).
NOTE
Ensure chamfered inner edge of snap ring faces outward.
(5)
Install shim(s) (89) and drive plate (88) on compressor (33). Press drive plate down as far as
possible by hand, install capscrew (87), and torque to 9 to 10 lbs-ft (12 to 14 Nm).
(6)
Measure for drive plate clearance of 0.01 to 0.02 in. (0.3 to 0.6 mm). Adjust thickness of shims (89)
to achieve clearance.
Installation
a.
Install compressor as follows:
(1)
If removed, install bracket (40, Figure 2-1-7) on engine with washers (38 and 35), one end of ground
wire (39), star washer (37), and capscrews (36 and 34).
(2)

(31, 29, 26, and 24), lockwashers (28 and 23), and nuts (27 and 22). Do not tighten nuts at this
time.
(3)
Position drive belt (41) on engine fan drive pulley and outer groove of compressor pulley, rotate
compressor (33) away from engine to tension drive belt until there is approximately 1/2 inch
deflection at midspan, then tighten nuts (22 and 27).
(4)
Attach other end of ground wire (39) to compressor (33) housing with capscrew (21), washer (20),
