GOVERNOR GP-UNIT INJECTOR 1407377 - Caterpillar

Excessive additive (greater than the recommended 6% initial fill) together with concentrations of antifreeze greater than 60% cause deposits to form and can result in radiator tube blockage and overheating.
1. Open the left engine access cover. 2. Loosen the radiator cap slowly to relieve pressure and remove the cap.3. It may be necessary to drain enough coolant from the radiator to allow for the addition of the liquid cooling system additive.4. Add 0.24 liters (1/2 pint) of additive for every 38 liters (10 U.S. gallons) of cooling system capacity.5. Install the radiator cap.6. Close the access cover.Belts
Inspect
For maximum engine performance and utilization of your engine, inspect the belts for wear and cracking. Check and adjust the belt tension to minimize belt slippage which will decrease belt life and cause poor performance of alternator, water pump, and any driven equipment. To check the belt tension, apply 110 N (25 lbs) of force midway between the pulleys. Correctly adjusted belts will deflect 13 to 19 mm (1/2 to 3/4 in).If new belt(s) are installed, check belt adjustment again, after 30 minutes of operation. For multiple belt drive applications, always replace belts in matched sets.If only one belt of a matched set is replaced, it will carry more of a load than the belts not replaced since the older belts are stretched. The additional load on the new belt could cause it to break.Water Pump Belt Adjustment
1. To Adjust the water pump drive belt, loosen mounting bolt (1) and bracket bolt (2).2. Move idler pulley in or out as required to obtain the correct adjustment.3. To make the correct adjustment, use the bolt in the center of the tightener pulley (3) or the square hole in the mounting bracket (4).4. Tighten bolts (1) and (2).5. If a new belt is installed, check the belt adjustment again after 30 minutes of engine operation at rated speed.Alternator/Fan Belts Adjustment
1. To adjust the alternator/fan belts, loosen mounting bolt (1) and bracket bolt (2) on the alternator bracket.2. Move alternator in or out as required to obtain the correct adjustment.3. Tighten bolts (1) and (2). Alternator shaft nut must be tightened to 50 5 N m (37 4 lb ft).4. Check and adjust the position of the fan shroud to ensure that the fan will not rub on the shroud. Maintain a 9.4 mm (.38 in) clearance between the fan and shroud.Feeder Gates
Lubricate the Fittings
All daily grease lubricant should be applied at the end of each machine operation while the machine is still warm and the asphalt is still soft or not set up. Failure to do so may allow asphalt to harden around the seals and risk damaging a seal and lead to premature bearing failure.
1. Open the front access covers. 2. Lubricate one fitting for each feeder gate. Total of two fittings.3. Close the access covers.Conveyor Drive Chains
Check the Chain Tension
Grab the auger with both hands and rotate it back and forth.If the auger rotates less than 13 mm (.50 in),
