the pulley by hand. Replace the clutch set with a

new one if it is noisy or has excessive play/drag

3. Measure the clearance betweenn the pulley (A) and

the pressure plate (B) with a dial indicator. Zero out

the indicator, then apply battery voltage to the

compressor clutch. Measure the movement of the

pressure plate when the voltage is applied. If the

clearance is not within the specified limits, the

pressure plate must be reshimed (see page 21-52).
