Steps for Clutch Installation
Step 1 — Install field
coil.
Reverse the procedure
outlined in Step 7 — Removing Clutch. Coil flange
protrusion must match hole in
front
housing to
prevent coil movement and correctly locate lead
wire.
Step 2 — Replace rotor pulley.
• Support the compressor on the four mounting
ears at the compressor rear. If using a vice,
clamp only on the mounting ears . . . never on
the compressor body.
• Align rotor assembly squarely on the front
housing hub.Fig. 78
Using Rotor Installer Set, place the ring part of the
set into the bearing cavity. Make certain the outer
edge rests firmly on the rotor bearing outer race.
• Place the tool set driver into the ring as shown.
Fig. 79
• With a hammer, tap the end of the driver while
guiding the rotor to prevent binding. Tap until
the rotor bottoms against the compressor front
housing hub. Listen for a distinct change of
sound during the tapping process. Fig. 80
Step 3 — Reinstall internal bearing snap ring with
pliers (Pinch type).
Step 4
—
Reinstall external front housing snap ring
with pliers (Spread type).
Step 5 — Replace front plate assembly.
• Check that the original clutch shims are in place
on compressor shaft.
• Replace compressor shaft key.
• Align front plate keyway to compressor shaft
key.
Using Shaft Protector, tap front plate to shaft
until it has bottomed to the clutch shims. Note
distinct sound change. Fig. 81
