A/C Compressor Clutch - Installation

A/C CLUTCH - VISTEON





1. Position the A/C clutch coil (1) squarely onto the front of the A/C compressor (2).

CAUTION: Position the A/C clutch field coil so that the coil positioning tabs and the wire harness lead are oriented in the correct direction. Failure to correctly position the field coil on the A/C compressor will result in field coil damage.

2. Align the coil positioning tabs to the recessed area at the front of the A/C compressor and install the clutch coil onto the compressor using a two jaw puller (3), Compressor Field Coil Installer 9352 (4) and Spacer 9353 (5).





3. Position the clutch coil wire lead and connector (3) to the A/C compressor (4) and install the plastic retaining clip (1) and the screw (2) that secures the wire lead to the compressor. Tighten the screw to 4 Nm (35 in. lbs.).





4. Align the pulley and bearing assembly (1) squarely onto the front of the A/C compressor (2).

NOTE: A distinct change of sound during the clutch pulley tapping process indicates that the pulley and bearing assembly has bottomed out against the compressor housing.

5. Using Clutch Pulley Installer 9355 (3) and a hammer (4), install the pulley and bearing assembly onto the front of the A/C compressor. Tap the installer with a hammer until the pulley and bearing assembly has bottomed against the compressor housing.






CAUTION: If the snap ring is not fully seated in the groove it will vibrate out, resulting in clutch failure and severe damage to the A/C compressor.

NOTE: Install the snap ring with the beveled side of the snap ring facing outward.

6. Using A/C Snap Ring Pliers 9764 (1) or equivalent, install the snap ring (2) that secures the pulley and bearing assembly (3) to the front of the A/C compressor (4). Make sure the snap ring is properly seated in the groove.





7. Verify that there is adequate clearance for the clutch field coil wire lead and connector (4) between the compressor housing and the pulley.

NOTE: When installing an original or a new clutch assembly, try the original shims first. When installing a clutch onto a compressor that previously did not have a clutch, use the 1.0, 0.50 and 0.13 millimeter (0.040, 0.020 and 0.005 inch) shims from the clutch hardware package which is provided with the new clutch.

8. Install the clutch shims onto the compressor shaft.
9. Using Compressor Clutch Holding Fixture 9351 (1), install the bolt (2) that secures the clutch plate (3) to the A/C compressor (5). Hold the clutch plate stationary with the fixture and tighten the bolt to 15 Nm (133 in. lbs.).





10. Using a feeler gauge (1), check the air gap between the clutch plate (2) and the pulley and bearing assembly (3). If the air gap is not 0.35 to 0.75 millimeter (0.014 to 0.030 inch), add or subtract shims as required.
11. Position the A/C compressor (4) onto the mounting bracket and install the fasteners A/C Compressor - Installation.
12. Connect the engine wire harness to the compressor clutch coil connector (5).
13. Lower the vehicle.
14. Install the accessory drive belt Serpentine Accessory Drive Belt - Installation.
15. Reconnect the negative battery cable.
