Clutch

The compressor clutch installation process begins with refrigerant evacuation from the system then moving on to disconnect the negative battery cable. The service starts with unclamping the battery hold down clamp and removing the battery tray and battery before moving to the No. 1 engine under cover subassembly. Following the removal of both fan and generator V belt you should disconnect the suction hose sub-assembly through bolt and nut removal. Then extract the O-ring from the suction hose while applying vinyl tape to its openings to avoid moisture and foreign matter intrusion. Carry out a discharge hose sub-assembly removal by removing the nut and O-ring and sealing the openings with vinyl tape. The cooler compressor assembly needs removal after disconnecting its connector and removing all four bolts. The installation process requires a step-by-step gas discharge through the service valve until an exact oil amount matches that of the removed compressor while using ND-OIL8 compressor oil. Finish the replacement process by inserting the 4 bolts into the cooler compressor assembly with 24.5 N.m (250 kgf.cm, 18 ft.lbf) torque and then reconnect the connector. To install the discharge hose sub-assembly first remove the vinyl tape then place an O-ring along with fitting surface under a layer of ND-OIL8 before installing the O-ring before mounting the discharge hose to the compressor with a nut featuring 9.8 N.m (100 kgf.cm, 87 in.lbf) torque. Torque the suction hose sub-assembly nut to 9.8 N.m (100 kgf.cm, 87 in.lbf) and bolt to 7.8 N.m (80 kgf.cm, 69 in.lbf) using this procedure once. Reinstall the fan together with the generator V belt while replacing the No. 1 engine under cover subassembly along with the battery tray, battery and battery hold down clamp which requires 6.0 N.m (61 kgf.cm, 53 in.lbf) torque setting. Affix the cable to the negative battery terminal before tightening it to 3.9 N.m (40 kgf.cm, 35 in.lbf). Afterwards charge the refrigerant before warming up the engine while inspecting for refrigerant leakage.

Reinstall the fan and generator V belt, the engine under cover sub-assembly No.1, charge the refrigerant, warm up the engine, and inspect for any refrigerant leakage.

Reconnect the screw and connector, then install the magnet clutch rotor and another new snap ring with the chamfered side facing up.

Evacuate air from the refrigeration system and charge it with refrigerant, using 600 ± 50 g (21.16 ± 1.76 oz.) for access cab and standard cab, or 530 ± 50 g (18.69 ± 1.76 oz.) for double cab.
