Installation Of Compressor
1. Mount the compressor.
Tightening torque: 31 - 46 N.m (3.2 - 4.7 m-kg, 23 - 34 ft-lb)
2. Connect the suction and discharge hoses to the compressor.
Tightening torque:
Discharge hose: 20 - 25 N.m (2.0 - 2.5 m-kg, 14 - 18 ft-lb)
Suction hose: 29 - 34 N.m (3.0 - 3.5 m-kg, 22 - 25 ft-lb)
3. Install the drive belt and check the drive belt deflection by applying moderate pressure 98 N (10 kg, 2.2 lb) midway between the pulleys.
Drive belt deflection:
New: 7 - 9 mm (0.27 - 0.35 in)
Used: 8 - 10 mm (0.31 - 0.39 in)
Tightening torque of lock bolt:
(A): 37 - 52 N.m (3.8 - 5.3 m-kg, 27 - 38 ft-lb)
(B): 37 - 52 N.m (3.8 - 5.3 m-kg, 27 - 38 ft-lb)
4. Check the drive belt tension at allowed part using a tension gauge.
Standard belt tension:
New : 687 - 883 N (70 - 90 kg, 154 - 198 lb)
Used: 589 - 785 N (60 - 80 kg, 132 - 176 lb)
5. Connect the magnetic clutch connector.
6. Connect the negative battery cable.
7. Evacuate, charge and test the refrigeration system.
