Clutch Plate & Hub Assembly

Begin compressor clutch replacement by removing refrigerant from the refrigeration system and cutting off the negative battery terminal cable which requires 90 seconds of waiting time before starting the task. You need to disconnect the No. 1 cooler refrigerant suction hose by unbolting the fastener while taking out the O-ring before applying vinyl tape at both openings to stop moisture and foreign material infiltration. Move on to the procedure of separating the No. 1 cooler refrigerant discharge hose in a similar process. The procedure starts with engine under cover removal along with fan and generator V belt before the cooler compressor assembly can be disconnected and its four bolts removed. The installation process requires fitting the four bolts on the cooler compressor assembly at a torque of 25 N.m (255 kgf.cm, 18 ft.lbf) and connecting the connector. The No. 1 cooler refrigerant discharge hose installation requires vinyl tape removal followed by adding compressor oil (ND-OIL 8 or equivalent) to a new O-ring and the fitting surface then adding the O-ring and screwing the hose in place using a bolt torqued to 9.8 N.m (100 kgf.cm, 7 ft.lbf). Rephrase the same procedure for installing the No. 1 cooler refrigerant suction hose. Reinstall the engine under cover RH before reestablishing the cable connection to the negative battery terminal and the fan along with generator V belt. Initialization steps must be done because selected vehicle systems need system initialization following battery connector removal. The technician should charge the refrigerant system after engine warm-up while checking for any refrigerant leakages.
