Installation

1. Clean all mounting surfaces.
2. With compressor in a vertical position (nose up), place clutch in position on the compressor front head. Make sure electrical connection is positioned correctly.
3. Place the coil pressing (installer) tool 49 UN01 046 over compressor nose and to the inner radius of the field coil.
4. Position 2-jaw puller tool on compressor and coil pressing tool. The jaws of the puller should be firmly engaged with the rear side of the compressor front mounts. The forcing screw must be piloted on the center mark of the pressing tool.
5. Tighten the forcing screw with a hand wrench until coil is pressed on the compressor. Check to make sure coil bottoms against head at all points around outside diameter.

NOTE
- Do not use air tools.

6. Clean pulley bearing surface of compressor head.
7. Install pulley and slip-fit pulley bearing on compressor.




8. Install snap ring with bevel side facing out.
9. Place one nominal thickness spacer shim on the end of the splined shaft and slide hub on the end of the compressor shaft.




10. Thread new 8 mm retaining bolt into end of compressor shaft. Tighten to 11 - 14 N.m (11.1 - 14.2 kgf.m, 8 - 10 lb-ft).

NOTE
- Do not use air tools.




11. Check clutch air gap between clutch disc and pulley mating surfaces with a feeler gauge. The air gap should be between 0.35 and 0.85 mm (0.014 and 0.033 inch). Check at three locations spaced around the pulley.
12. If clutch air gap is not within specification, repeat steps 4 through 6 with various thickness shims until air gap is within specification.
13. Leak test, evacuate and charge the system.
14. Cycle clutch ten times at idle to burnish the clutch and prevent slippage.
