(4) Remove coil wire bracket/ground clip screw and
wire harness.
(5) Remove snap ring retaining field coil onto com-
pressor housing (Fig. 14). Slide field coil off of com-
pressor housing.
(6) Examine frictional faces of the clutch pulley
and front plate for wear. The pulley and front plate
should be replaced if there is excessive wear or scor-
ing. If the friction surfaces are oily, inspect the shaft
nose area of the compressor for oil and remove the
felt from the front cover. If the compressor felt is sat-
urated with oil, the shaft seal is leaking and will
have to be replaced.
(7) Check bearing for roughness or excessive leak-
age of grease. Replace bearing as required.
INSTALLATION
(1) Align pin in the back of the field coil with hole
in compressor end housing, position the field coil into
place. Make sure that lead wires are properly routed,
and fasten the coil wire bracket/ground retaining
screw.
NOTE: A new snap ring must be used. The bevel
side of the snap ring must be outward.
(2) Install field coil retaining snap ring with Snap
Ring Pliers. Press snap ring to make sure it is prop-
erly seated in the groove.
CAUTION:
If snap ring is not fully seated it will vibrate out,
resulting in a clutch failure and severe damage to
the front face of the compressor.
Do not mar the pulley frictional surface.
(3) Install pulley assembly to compressor. If neces-
sary, tap gently with a block of wood on the friction
surface (Fig. 15).
(4) Install pulley assembly retaining snap ring
(bevel side outward) with Snap Ring Pliers. Press the
snap ring to make sure it is properly seated in the
groove.
(5) If the original front plate assembly and pulley
assembly are to be reused, the old shim(s) can be
used. If not, place a trial stack of shims, 2.54 mm
(0.10 in.) thick, on the shaft against the shoulder.
(6) Install front plate assembly onto shaft.
(7)
If installing a new front plate and/or pulley
assembly, the gap between front plate and pulley face
must be checked. Use the following procedure:
(a) Attach a dial indicator to front plate so that
movement of the plate can be measured.
(b) With the dial indicator zeroed on the front
plate, energize the clutch and record the amount of
movement.
(c) The readings should be 0.35 to 0.65 mm
(0.014 to 0.026 in.). If proper reading is not
obtained, add or subtract shims until desired read-
ing is obtained.
