Installing the Air Conditioning Compressor
Operator Cab: Service and Repairs

1. Flange nut
The compressor must be positioned with the larger (suction) port
toward the outside of the machine.
1. Position the compressor to the compressor mount on the machine frame.
2. Ensure that the clearance between the compressor mounting flanges and
compressor bracket is less than 0.10 mm (0.004 inch). If necessary, install
shims between the compressor flanges and bracket to adjust clearance.
3. Position the compressor with smaller refrigerant port closest to the engine
and secure the compressor to the compressor mount with the 2 screws (item
18 in Figure 319) and 2 locknuts.
After the compressor is installed, ensure that you rotate the
compressor driveshaft several times to correctly distribute the oil in
the compressor. Perform this procedure to prevent damage of the
compressor because of the oil slugging.
4. Manually rotate the compressor driveshaft at least 10 revolutions to ensure
that there is no compressor oil in the compressor cylinders.
5. Install the air conditioning compressor drive belt. Adjust the drive belt tension
until the belt deflection is 7.6 mm (0.30 inch) at 10 kg (22 lb) force applied
half way between the engine and compressor pulleys, and tighten the nut
that secures the idler pulley
6. Remove the caps that you placed on the hoses and fittings during the removal
process. Use the labels that you attached during removal to correctly attach
the hoses to the compressor. Torque the discharge hose fitting (smaller
fitting) and suction hose fitting (larger fitting) as shown in
7. Connect the compressor electrical connector to the machine wire harness.
