Remove the pulley retaining snap ring and then pull the pulley and bearing assembly from the compressor.
Remove the clutch hub retaining bolt with the aid of a spanner wrench.
Pull the clutch hub. If the hub can not be pulled from the compressor shaft, screw an 8 mm bolt into the shaft hole of the clutch hub to force thehub from the shaft.
Remove the pulley retaining snap ring and then pull the pulley and bearing assembly from the compressor.
Remove the clutch hub and pulley following the procedure given.
Install shaft protector tool on the nose opening of the compressor.
Install the pulley on the compressor as shown in the illustration. Place the tip of the puller screw on the center dimple of the shaft protector andthe jaws of the puller around the back side of the field coil.
Tighten the forcing screw with a wrench to pull the coil loose from the compressor front head.
After reassembling the compressor assembly by the reverse of the disassembly procedure given, check the clutch air gap between the clutch hub and the pulleymating surface with a feeler gauge. The air gap should be as follows.
Air gap : 0.35 - 0.65 mm (0.014 - 0.026 inch) |
When reassembling the compressor assembly, clean the pulley bearing surface and coil press diameter of the front head to remove any dirt or corrosion.
If the clutch air gap is not within the dimensions specified above, adjust the various thickness shims until the air gap is within the specifiedlimits.
If a new compressor is installed, first adjust the amount of oil according to the procedures described below, and then install the compressor.
Measure the amount (X cm³) of oil inside the removed compressor.
Y cm³ indicates the amount of oil in the refrigerant line, the condenser, the cooling unit, etc.
When replacing the following parts at the same time as the compressor, subtract the rated oil amount of each part from Y cm³ and discharge thisamount from the new compressor.
Compressor oil: FD46XG (PAG OIL) |
Quantity: Evaporator: 30 cm³ (1.0 fl.oz.) Condenser: 40 cm³ (1.4 fl.oz.) Suction hose: 10 cm³ (0.3 fl.oz.) Receiver: 20 cm³ (0.6 fl.oz.) |
