A/C Compressor - Transferring Drive Clutch to new Compressor - Clearance Adjustment

Issue:

Air Conditioning Compressors are supplied without the Drive Clutch Assembly. The drive clutch assembly must be transferred to the new

compressor. A clearance adjustment is necessary when the clutch is assembled on the compressor. This bulletin provides a listing of the shim part

numbers and the procedure which is also in section 412-03 on JTIS 9.

Action:

DISASSEMBLY

1. Discharge the refrigeration system and remove the compressor from the engine. Always plug the refrigerant suction and outlet ports and the

disconnected pipes immediately, to contain the residual oil and to prevent the entry of moisture or dirt.

2. Install and tighten Special Tool 303-D055 (Universal Strap Wrench) around the clutch plate.

3. Loosen the center clutch retaining nut. Remove the nut and the clutch plate.

4. Remove the shim from the shaft.

5. Remove the clutch pulley circlip.

6. Use Special Tool 303-D121 (Crankshaft Damper Remover), to pull the clutch pulley from the shaft.

7. Remove the retaining bolt and plate, allowing the sensor to be detached from its location on the compressor body

8. Remove the clutch field coil retaining circlip.

9. Remove the clutch field coil assembly

ASSEMBLY

1. Install the clutch field coil assembly to the compressor and install the retaining circlip.

2. Align the sensor to its location on the compressor body and install the retaining plate and bolt.

3. Using Special Tool 412-109 if necessary, install the clutch pulley to the compressor shaft.

NOTE:

The bearing of the clutch pulley should be a slip-install on the drive shaft, enabling the assembly to be pushed home by hand. If necessary,

align the above tool with the bearing and shaft, and use light hammer blows to tap the bearing fully into position.

4. Install the clutch pulley circlip.

5. Install the shim (removed in step 4 above) on the shaft.

6. Install the clutch, start the retaining nut, and finally tighten the nut, Use Special Tool 303-DOSS Strap Wrench to prevent the clutch plate from

rotating. Torque Wrench Setting: 17 Nm (13 lb. ft.)

7. Using feeler gauges, determine the air gap clearance between the rear face of the clutch plate and the pulley Specified Clearance: 0.35 - 0.75

mm (0.010 - 0.030 inch).

8. If the measured air gap is not within the above limits, remove the clutch plate and add or remove shims as necessary to obtain the specified

clearance.

9. Reinstall the compressor assembly to the engine.

Note:

Install new 0-rings, wetted with compressor lubricating oil, when reconnecting the refrigerant suction and outlet connections at the

compressor. Do not return to the bottle any oil used in connection with moistening of the 0-rings. Immediately reinstall the cap on the

bottle, to reduce absorption of moisture from the atmosphere. Replacement compressors are supplied pre-filled with the correct quantity of

oil.

If an existing compressor is reinstalled, but oil is lost during the process of installing new clutch components, replace the amount of oil

lost.

10. Recharge the system with refrigerant.
