BELT PULLEY WITH A/C Clutch -N25- INFORMATION
- If the belt pulley overload protection is triggered, then the A/C compressor must be checked for ease of movement before replacing the belt pulley. If the A/C compressor is difficult to move, this must be replaced completely.
- In most cases it is not necessary to loosen the A/C compressor from the engine to remove the drive plate. Depending on the engine type, it may be necessary to loosen the lock carrier from the vehicle and to pull it slightly forward (to make space). Refer to LOCK CARRIER, REMOVING AND INSTALLING .
- If the belt pulley cannot be removed with the A/C compressor installed depending on the vehicle and engine, remove the A/C compressor with the refrigerant lines connected. Refer to A/C COMPRESSOR, REMOVING AND INSTALLING FROM BRACKET .
- Depending on the A/C compressor type and the engine version, different versions of the belt pulley may be installed (different diameters). Refer to the Parts Information.
- The replacement belt pulley with A/C clutch has a single part number. The belt pulley and the drive plate are held together with one bolt (when the bolt is no longer needed, dispose of it). When the bolt was manufactured, a predetermined amount of a specific grease was applied to the threads in the drive plate; this amount is sufficient for bolting the drive plate to the compressor one time (a drive plate, which has been removed, cannot be reused). Refer to the Parts Information.
- The following image shows an A/C compressor with a particular connector for activating the A/C Clutch -N25- (a specific connector is equipped on this A/C compressor for activating the A/C Compressor Regulator Valve -N280-. For another A/C compressor version, the wires to activate the A/C Clutch -N25- and the A/C Compressor Regulator Valve -N280- are combined in a 3-pin connector. If necessary, discard the line to the A/C Clutch -N25- using a suitable release tool from the Wiring Harness Repair Set :VAS1978B from the connector. Refer to CONNECTOR HOUSINGS, RELEASING AND DISASSEMBLING .
