INSPECTION FOR CLUTCH DISC TO PULLEY CLEARANCE
1. Check the clearance around the entire periphery of the clutch disc.
• Measure the clearance for the type 1 compressor as shown.
• Measure the clearance for the type 2 compressor as shown.
2. If specified clearance is not obtained, replace compressor.
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
• Replace O-rings of low-pressure flexible hose and high-pressure flexible hose with a new ones, and
apply compressor oil when installing.
• When recharging refrigerant, check for leaks.

Checking of Refrigerant LeaksINFOID:0000000001704333
Perform a visual inspection of all refrigeration parts, fittings, hoses and components for signs of A/C oil leak-
age, damage and corrosion. A/C oil leakage may indicate an area of refrigerant leakage. Allow extra inspec-
tion time in these areas when using either an electronic refrigerant leak detector or fluorescent dye leak
detector.
If dye is observed, confirm the leak with an electronic refrigerant leak detector. It is possible a prior leak was
repaired and not properly cleaned.
When searching for leaks, do not stop when one leak is found but continue to check for additional leaks at all
system components and connections.
When searching for refrigerant leaks using an electronic leak detector, move the probe along the suspected
leak area at 25 to 50 mm (1 to 2 in) per second and no further than 1/4 inch from the component.
CAUTION:
Moving the electronic leak detector probe slower and closer to the suspected leak area will improve
the chances of finding a leak.
