Compressor

The procedure for w/pulley compressor assembly replacement starts with refrigerant discharge from the refrigeration system by using Special Service Tool: 07110-58060 (07117-58080, 07117-58090, 07117-78050, 07117-88060, 07117-88070, 07117-88080). The fan and generator V belt should be removed along with cooler refrigerant discharge hose No.1 by unfastening its bolt and O-ring before sealing each opening with vinyl tape to block moisture and foreign material entry. Afterwards disconnect the suction hose sub assembly by removing its bolt together with its O-ring before sealing all openings. Detach both the engine under cover RH and w/pulley compressor assembly by removing its connector and 4 bolts. Before installing the new compressor and magnetic clutch users should inspect the oil amounts and use ND-OIL 8 as the compressor oil. The w/pulley compressor assembly must be installed with four bolts reaching a torque of 25 Nm and connected to power. The suction hose sub assembly installation necessitates vinyl tape removal followed by the application of compressor oil to a new O-ring installation before bolt tightening to 9.8 Nm (100 kgf.cm) (87 in.lbf). Follow the same procedure for cooler refrigerant discharge hose No.1 by applying compressor oil to the new O-ring then torquing the bolt to 9.8 Nm (100 kgf.cm, 87 in.lbf). The installation process of the fan and generator V belt should be followed by belt adjustment while the charging of the refrigerant requires the use of Special Service Tool: 07110-58060 (07117-58060, 07117-58070, 07117-58080, 07117-58090, 07117-78050, 07117-88060, 07117-88070, 07117-88080) to maintain a 460 plus or minus 30 g (16.2 plus or minus 1.1 oz.) measurement of refrigerant before engine warm-up to verify no leakage occurs.

Refrigerant removal from the refrigeration system begins through the use of Special Service Tool: 07110-58060 (07117-58080, 07117-58090, 07117-78050, 07117-88060, 07117-88070, 07117-88080). Disconnection starts with removing the V belt from fan and generator after which technicians must detach cooler refrigerant discharge hose No.1 by unfastening the bolt and then its O-ring. Finally, technicians will close off the tubings with vinyl tape to halt moisture and foreign materials from entrance. The procedure requires removal of a suction hose sub assembly bolt together with its O-ring before sealing the open ends. Begin by removing the engine under cover RH followed by disconnecting the w/pulley compressor assembly through the connector removal and bolt removal of four pieces. The appropriate amount of compressor oil needs to be drained from the new components before installation while using ND-OIL 8 as the compressor oil. Fasten the w/pulley compressor assembly using four bolts, torqued at 25 Nm (255 kgf.cm, 18 ft.lbf) and identity the connector to its place. The procedure for installing the suction hose sub assembly includes vinyl tape removal followed by applying compressor oil on a new O-ring then bolting installation with torque setting at 9.8 Nm (100 kgf.cm, 87 in.lbf). The procedure for cooler refrigerant discharge hose No.1 requires applying compressor oil on the new O-ring before torquing the bolt to 9.8 Nm (100 kgf.cm, 87 in.lbf). The operator should now reinstall the fan and generator V belt followed by adjustment before performing a refrigerant charge with Special Service Tool: 07110-58060 (07117-58060, 07117-58070, 07117-58080, 07117-58090, 07117-78050, 07117-88060, 07117-88070, 07117-88080) using 460 plus or minus 30 g (16.2 plus or minus 1.1 oz.) of specified refrigerant. To complete the service procedure you need to heat the engine before checking for leakage of refrigerant.

Warm up the engine and inspect for refrigerant leakage.

Remove the vinyl tape, apply compressor oil to a new O-ring, install it, and secure the assembly with a bolt.
