To check the belt tension, apply 110 N (25 lb) of force midway between the pulleys. Correctly adjusted belts will deflect 14 to 20 mm (1/2 to 3/4 inch).
In order to adjust the alternator belt, loosen bracket bolt (2) and mounting bolt (1) on the alternator bracket.
To achieve the correct adjustment, move the alternator inward or move the alternator outward, as required.
Tighten mounting bolt (1) and bracket bolt (2). Air Conditioner Belt (If Equipped)
Stop the engine in order to inspect the air conditioner belt.
Inspect the condition of the air conditioner belt and the adjustment of the air conditioner belt. The air conditioner belt should deflect 14 to 20 mm (0.55 to 0.79 inch) under 110 N (25 lb) of force.
Loosen compressor mounting bolts (3) and (4). Loosen compressor bracket mounting bolt (5).
Move the compressor until the correct belt tension is reached.
Tighten compressor bracket mounting bolt (5). Tighten compressor mounting bolts (3) and (4).
Recheck the belt deflection. If the amount of deflection is incorrect, repeat Step 3 to Step 5.
Start the engine. If poor cooling is still experienced, turn off the air conditioner. Stop the engine. Notify your Caterpillar dealer for air conditioner system service.
