10. Check the idler pulley bearing for play and drag,
and replace it with a new one if it's noisy or has
excessive play or drag.
lnstall in the reverse order of removal. Make note of
the following items,
. lf you're installing a new compressor, drain all the
reJrigerant oil from the removed compressor, and
measure its volume. Subtract the volume of
drained oil trom 130 m/ 14 U3 fl'o2,4.6 lmp'oz);
the result is the amount of oil you should drain
lrom the new compressor (through the suction fit-
trngl.
. Replace the O-rings with new ones at each fit-
ting, and apply a thin coat o{ refrigerant oil
before installing them. Be sure to use the right
O-rings for HFC-134a (R-134a) to avoid leakage.
. Use refrigerant oil (SP-10) for R-134a KEIHIN spi-
ral type compressors only.
. To avoid contamination, do not return the oil to
the container once dispensed, and never mix it
with other refrigerant oils.
. lmmediately after using the oil, replace the cap
on the container. and seal it to avoid moisture
aDsorprlon.
. Do not spill the refrigerant oil on the vehicle; it
may damage the paint; if the retrigerant oil con-
tacts the Daint, wash it off immediately.
. Adjust the Ay'C compr'essor b€lt (see psge 22-69)
and the power steering pump belt {see section
17t.
. Charge the system (see page 22-611, and test its
performance (see page 22-56]-.

Clutch Inspection
Check the plated parts of the armature plate for color
changes, peeling or other damage. lf there is dam-
age, replace the clutch set.
Check the rotor pulley bearing play and drag by rotat-
ing the rotor pulley by hand. Replace the clutch set
with a new one if it is noisy or has excessive play/drag.
Measure the clearance between the rotor pulley and
the armature plate all the way around. lf the clear-
ance is not within specified limits, the armature plate
must be removed and shims added or removed as
required, following the procedure on page 22-66.
Cloarance: 0.5 t 0.15 mm {0.020 t 0.q)6 in)
NOTE: The shims are available in four thicknesses:
0.1 mm. 0.2 mm. 0.4 mm and 0.5 mm

. Release the field coil connector from the holder, then
disconnect it. Check the thermal protector for conti-
nuity, lf there is no continuity, replace the thermal
prorecror.
NOTE: The thermal protector will have no continuity
above 251.6 to 262.4"F 1122 to 128"C). When the tem-perature drops below 240.8 to 219.8"F (116 to 104'C),
the thermal protector will have continuity.
Check resistance of the field coil.
Field Coil Resistance: 3.2 i 0.15 ohms at 68"F {20'C)
lf resistance is not within specifications, replace the
field coil.

Reassemble the comDressor clutch in the reverse
order of disassembly. Make note of the following
rrems.
Install the field coil with the wire side facing down,
and align the boss on the tield coil with the hole in
the compressor.
Clean the rotor pulley and compressor sliding
surfaces with non-oetroleum solvent.
lnstall new snap rings A and B.
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.
