pressor housing (Fig. 4). Slide field coil off of com-
pressor housing.
Fig. 4 Clutch Coil Snap Ring
(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 back of field coil with hole in com-
pressor end housing, and position field coil into place.
Make sure that lead wires are properly routed, and
fasten the coil wire bracket/ground retaining screw.
(2) Install field coil retaining snap ring with Snap
Ring Pliers (C-4574). The bevel side of the snap ring
must be outward. Also both eyelets must be to the
right or left of the pin on the compressor. Press snap
ring to make sure it is properly seated in the groove.
CAUTION: If snap ring is not fully seated it will vi-
brate out, resulting in a clutch failure and severe
damage to the front face of the compressor.
CAUTION: 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. 5).
Fig. 5 Installing Pulley Assembly
(4) Install pulley assembly retaining snap ring
(bevel side outward) with Snap Ring Pliers (C-4574).
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.
