Air Compressor
For balance of engine and air compressor reciprocating
force, the coupling driven air compressor must be timed
to engine firing order.
1. Bar engine to "B" or "2-5" valve set mark.
2. Rotate air compressor crankshaft so male splined
coupling half key-way will be pointing directly away from
engine (3 o’clock position when looking at coupling end
of compressor).
3. Assemble splined coupling to air compressor drive
shaft.
4. With a new gasket in place, position air compressor
coupling to accessory drive shaft; secure air compressor
to accessory drive housing. Connect air and water lines
to compressor.

Fig. 4-1 1, as used for checking accessory drive gear
backlash.
Note:
If power steering pump is driven by lubricating oil
pump, position coupling to shaft, install power steering
pump.
4. When used, secure oil filter can with new element and
sealing "O" ring to lubricating oil pump by torquing center
bolt to 25 to 35 ft-lb. [3.5 to 4.8 kg m] .
