43. Slip the short v-belt onto the rear groove of the compressor. Slip the long belt onto the
front groove of the compressor.
44. Take a 3/8” x 1 ½” flange bolt and nut and start the tensioner fastener on the compressor.
Firmly fasten the two compressor ear pivot bolts first. Then, apply tension to the compressor in
order to properly tension the main engine drive belt and tighten the tensioner bolt.
45. Take the alternator and slide it into the alternator opening on the compressor bracket.
Slide the short belt onto the alternator before positioning as it will be very difficult afterwards.
For the alternator pin, use the provided 3/8” x 2”
hex bolt and nut. Slide the bolt through the
pin, and then slide the alternator support bracket onto the back of the bolt and then loosely
fasten.
.
46. Re-using the alternator tensioner fastener for the tensioner position on the new bracket.
Tighten the pin fastener first, and then apply tension for the alternator and tighten fastener.
47. Loosen the engine wire harness tie down in order to re-connect the alternator to the engine
harness. It may be necessary to lengthen the sending unit wire in the harness if it is not long
enough. Wire and shrink-wrap are provided for lengthening the three wires going to the
alternator if necessary. Proceed with extending one wire at a time using the red 12 GA wire for
the heavy power wire in the harness, white wire for the white wire, and the orange wire for the
remaining wire. SOLDER and shrink wrap both ends of the wires.
48. Route the hoses along with the compressor clutch wire on the right side of the cab under
the hood and air intake filter. Install the hoses onto the compressor. Zip tie the hoses so that
they do not interfere with any moving parts on the engine.
