COMPRESSOR NOISE CHECK
You must first know the conditions when the noise occurs. These conditions are: weather, vehicle speed,
in gear or neutral, engine temperature or any other special conditions.
Noises that develop during A/C operation can often be misleading. For example: what sounds like a
failed front bearing or connecting rod, may be caus ed by loose bolts, nuts, mounting brackets, or a
loose clutch assembly. Verify accessory drive belt tension (power steering or generator).
Improper accessory drive belt tension can cause a m isleading noise when the compressor is engaged
and little or no noise when the compressor is disen gaged.
Drive belts are speed-sensitive. That is, at differ ent engine speeds, and depending upon belt tension,
belts can develop unusual noises that are often mis taken for mechanical problems within the compressor .
ADJUSTMENT
1. Select a quiet area for testing. Duplicate conditions as much as possible. Switch compressor on
and off several times to clearly identify compresso r noise. To duplicate high ambient
head pressure), restrict air flow through condenser . Install manifold gauge set sure discharge
pressure doesn’t exceed 2,070 (300 psi).
2. Tighten all compressor mounting bolts, clutch mo unting bolt, and compressor drive belt. Check to
assure clutch coil is tight (no rotation or wobble) .
3. Check refrigerant hoses for rubbing or interfere nce that can cause unusual noises.
4. Check refrigerant charge. (Refer to
5. Recheck compressor noise as in Step 1.
6. If noise still exists, loosen compressor mountin g bolts and retorque. Repeat Step 1.
7. If noise continues, replace compressor and repea t Step 1.

AIR GAP ADJUSTMENT
Check whether or not the air gap of the clutch is w ithin the
standard value.
Standard value: mm
NOTE
If there is a deviation of the air gap from the value,
make the necessary adjustment by adjusting the numb er of
shims.
INSPECTION
lCheck the of the armature for scoring or bluing.
lCheck the surface of the rotor for scoring or bluing.
l Check the sealing surfaces for cracks, scratches an d
deformation.
lCheck the front housing for cracks or scoring on the sealing
surfaces.
lCheck the compressor shaft for scoring.
