5. Remove the screw from the field coil ground termi-
nal, then disconnect the field coil connector.
Remove snap ring A with snap ring pliers, then
remove the field coil
NOTE:
. Be careful not to damage the field coil and com-
pressor during remove/installation.
. Once snap ring A is removed, replace it with a
new one.
. When installing the field coil, align the boss on
the field coil with the hole in the compressor.
SNAP RING AReplace.
Position the rotor pulley squarely over the field coil.
Press the rotor pulley onto the compressor boss
with the special tool. lf the rotor pulley does not
press on straight, remove it, and check the rotor
pulley and compressor boss for burrs or damage.

Make note of the following items.
. lnstall the field coil with the wire side facing down.
. Clean the rotor pulley and compressor sliding
surfaces with non-petroleum solvent.
. Make sure the snap rings are fully seated in the
groove.
. Make sure that the rotor pulley turns smoothly
after it's reassembled
. Route and clamp the wires properly or they can
be damaged bY the rotor Pulley.

Clutch Inspection
Check the plated parts of the pressure plate for colo.changes, peeling or other damage. lf there is dam-age, replace the clutch set.
Check the pulley bearing play and drag by rotatingthe pulley by hand, Replace the clutch set with a newone if it is noisy or has excessive play/drag.
Measure the clearance between the pullev and thepressure plate all the way around. lf the clearance isnot within specified limits, the pressure plate must beremoved and shim(s) added or removed as required,
following the procedure on page 22-41.
Clearanca:0.5 t 0.15 mm {0.020 r 0.006 in}
NOTE: The shims are availabte in three thicknesses:0.1 mm,0.3 mm and 0.5 mm.
