Belts
Inspect - Adjust
Your engine can be equipped with water pump, fan drive, alternator, and accessory drive belts. 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 14 to 20 mm (9/16 to 13/16 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, Fan, and Alternator Belts Adjustment
1. To adjust the belts, loosen mounting bolt (1) and bracket bolt (2) on the alternator bracket.2. Move the alternator in or out as required to obtain the correct adjustment.3. Tighten bolts (1) and (2) to a torque of 100 7 N m (70 5 lb ft).4. If new belts are installed, check the belt adjustment again after 30 minutes of engine operation at rated speed. Replace belts in matched sets only. 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.Air Conditioner Belt Adjustment (If Equipped)
An incorrectly tensioned V-belt could cause not only a decrease of the compressor performance but damage to the belt and compressor.
1. Measure the deflection of the belt.2. Apply approximately 98 N (22 lb) force midway between the pulleys. The belt should deflect 7 to 10 mm (5/16 to 7/16 in).3. If the deflection is not correct, loosen bolts (1), (2), (3), and lock nuts (4) and move the air conditioner compressor up or down to loosen or tighten the belt. After the belt is correctly adjusted, tighten bolts (1) and (3) and locknuts (4) to a torque of 105 20 N m (75 15 lb ft). Tighten bolt (2) to a torque of 47 9 N m (35 7 lb ft).4. Check the adjustment again.Final Drives
Check the Oil Level
1. Position one final drive with oil drain plug (1) at the bottom.2. Remove oil level plug (2).3. Oil should be to the bottom of the oil level plug opening. Refer to the General Hazard Information section for information on Containing Fluid Spillage.4. Add oil through the opening of the oil level plug, if necessary. Overfilling the final drive will cause the travel motor seals to allow hydraulic oil or water to enter and contaminate the drive.5. Clean oil level plug (2). Inspect the O-ring seal. Replace it if it is
