- 5. 3 Installation ofthe Air Compressor Install as follows: 1. If removed, install the air compressor gear to the air compressor shaft and secure with nut. Thread is left-handed; torque nut to 210-250 N·m (155-185 lb·ft). 2. Clean all foreign material from the mating surfaces of the air compressor and the cylinder block. 3. Install a new O-ring on the air compressor hub and a new O-ring on the oil supply, and then install the air compressor on the cylinder block. Torque the four bolts to 60 N·m (44 lb·ft). NOTICE: Ensure the correct bolt length is used when the air compressor is installed. If an incorrect bolt length (too long) is used, the cup plugs installed in the cylinder block can be pushed out into the gear train causing severe damage to the gear train. The correct bolt length is 35 mm (1.37 in.). NOTICE: Ensure when the air compressor coolant lines are installed that there is an O-ring and an O-ring retainer installed on both ends of the coolant lines. Ensure that the air compressor retainer is installed on the coolant line and is pushed down to lock the lines onto the inlet and outlet ports to the cylinder block, fuel filter module and air compressor. A leak will occur if the lines are incorrectly installed and the coolant line retainer is not engaged in the locked position. If the O-ring or the coolant line retainers are missing or removed, replace the coolant line. 4. Install the coolant supply and return lines to the air compressor. 5. Install the air lines to and from the air compressor. Refer to OEM specifications. 6. Fill the cooling system. Refer to OEM specifications. 7. Start the engine and check for leaks. 12 08-10 All information subject to change without notice. 7 12 8-10 Copyright © 2011 DETROIT DIESEL CORPORATION
