NOTE:
. Clean all parts thoroughly in solvent or carburetor cleaner, and dry them with compressed air. Blow out all passages.
. Replace the valve body as an assembly if any parts are worn or damaged.
. Checkall valvesforfree movement. lf anyfailto slide freely, seeValve Body Repairon page 14-192.

Wheel Sensor
The wheel sensors are the magnetic contactless type. As the gear pulser teeth rotate past the wheel sensor's magnetic
coil, AC current is generated. The AC frequency changes in accordance with the wheel speed. The ABS control unit detects
the wheel sensor signal frequency and thereby detects the wheel speed
at LOW SPEED

When the wheel speed drops sharply below the vehicle speed, the outlet valve opens momentarily to reduce the caliper
fluid pressure. The pump motor starts at this time. As the wheel speed is restored. the inlet valve opens momentarily to
increase the caliDer fluid oressure.

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.

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.

ROTORPULLEY
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.

Relief Valve Replacement
l.Recover the refrigerant with a Recovery/Recycling/
Charging System (see page 22-59).
Remove the relief valve cover ('97 model), the relief
valve and the O-ring. Plug the opening to keep for-
eign matter from entering the system and the com-
pressor oil from running out.
O.RINGReplace.

Put the cover on the relief valve so that the arrow
directs downwards as shown in the illustration
above ('97 model).
Clean the mating surfaces.
Replace the O-ring with a new one at the relief valve,
and apply a thin coat of refrigerant oil before
installing it.
Remove the plug. and install and tighten the relief
valve.
7. Charge the system (see page 22-61), and test its
performance (see page 22-561r.
