Ensure clutch coil lead is positioned properly. Ensure snap rings are installed with beveled side facing
out. Tighten shaft bolt to 10-13 ft. lbs. (14-17 N.m).
2. Check air gap between clutch plate and pulley. Position dial indicator on clutch plate. Energize clutch coil
and zero dial indicator. De-energize clutch coil and measure air gap (clutch plate movement). Ensure air
gap between clutch plate and pulley is 0.014-0.026" (0.35-0.65 mm). If air gap is incorrect, add or remove
shim(s) as necessary. Ensure pulley rotates freely.
Removal (All Others)
1. Hold clutch plate stationary, and remove clutch plate center nut or bolt. On Lexus and Toyota, remove
clutch plate using Clutch Plate Remover (07112-66040). On other models, remove clutch plate using a 2-
jaw or 3-jaw puller.
2. On all models, remove shim(s) and pulley snap ring. See Fig. 6
, Fig. 7 , or Fig. 8 . Tap pulley off
compressor shaft using a plastic hammer. If pulley cannot be removed, use a 2-jaw or 3-jaw puller.
Position puller jaws onto edge of pulley to prevent pulley groove from being deformed. Disconnect clutch
coil lead. Remove clutch coil snap ring and clutch coil.
Installation
1. To install, reverse removal procedure. Ensure clutch coil is positioned correctly. Ensure new snap rings
are installed with beveled side facing out. On Lexus and Toyota, tighten clutch plate center bolt to 115
INCH lbs. (13 N.m). On all other models, tighten shaft bolt (or nut) to 11-15 ft. lbs. (15-20 N.m).
2. On Lexus and Toyota, ensure air gap between clutch plate and pulley is 0.014-0.026" (0.35-0.65 mm). On
all other models, ensure air gap between clutch plate and pulley is 0.016-0.024" (0.41-0.61 mm). On all
models, if air gap is incorrect, add or remove shim(s) as necessary.
NOTE: On some compressors, it is necessary to use a dial indicator on clutch plate to
check air gap. Energize clutch coil and zero dial indicator. De-energize clutch
coil and measure air gap. Ensure air gap is as specified.
