Inspect Belts
1. Remove belt guard. 2. Inspect the belts for wear. Replace belts if worn, cracked or frayed.When belt replacement is necessary, belts must be replaced in complete matched sets. Never replace only one belt. The new belt will carry all of the load and consequently, fail rapidly.3. If belts do not require replacement or adjustment, install the belt guard. If belts require adjustment or replacement, do not install the belt guard. See "Adjust Belts" when belt adjustment and/or replacement is necessary.Adjust Belts
To Adjust Alternator Belts
1. Apply a 110 N (25 lb) force perpendicular to the belt, midway between the driving and driven pulley. Measure the belt deflection. Proper belt deflection is 15 to 20 mm (.6 to .8 inch). Adjust the belt tension as required.2. Loosen locknut (1) on the belt tightener rod.3. Turn adjustment nut (2) until correct belt deflection is obtained.4. Tighten locknut (1).5. Check the belt adjustment.6. Install the belt guard.To Adjust Fan Drive Belts
1. Loosen six bolts (1) holding the fan mounting plate to the engine.2. Loosen locknut (2). Turn adjusting screw (3) until the belts are properly adjusted.3. Tighten six bolts (1) and locknut (2).4. Check the belt adjustment. If adjustment is not correct, repeat steps 1 through 3.Fan Drive Bearing and/or Belt Tightener Group
Fan Drive Bearing
Some fan drive groups have a pressure relief fitting (1) and a grease fitting (2). Do not replace the pressure relief fitting with a grease fitting. A failure can result.
Lubricate fan drive bearing grease fitting (2).Belt Tightener Bearing
Some belt tightener groups have a pressure relief fitting (1) and a grease fitting (2). Do not replace the pressure relief fitting with a grease fitting. A failure can result.
Lubricate belt tightener grease fitting (2).Cooling System
Add Coolant Conditioner
At operating temperature, the engine coolant is hot and under pressure.Check the coolant level only when the engine is stopped and the radiator filler cap is cool enough to touch with your bare hand.Remove the radiator filler cap slowly to relieve pressure.Steam can cause personal injury.Cooling System Conditioner contains alkali. Avoid contact with skin and eyes to prevent personal injury.
All water is corrosive at engine operating temperature. Use either Caterpillar Cooling System Conditioner, or Coolant Conditioner Element to treat either plain water or ethylene glycol antifreeze solution. Never use both the cooling system conditioner and the coolant conditioner element at the same time.Do not use Caterpillar Cooling System Conditioner or Coolant Conditioner Elements with Dowtherm 209 Full-Fill coolant. Follow recommendations provided with Dowtherm 209 Full-Fill coolant.
Add .5 liter (1 pint) of Caterpillar Cooling System Conditioner for each 75 liters (20 U.S. gallons) of coolant used. This will maintain the required 3% to 6% concentration of conditioner.
Typical Example1. Remove radiator filler cap slowly to relieve pressure.It may be necessary to drain enough coolant to allow for the addition of cooling system conditioner.2. Add Caterpillar Cooling System Conditioner.3. Inspect radiator filler cap gasket. Replace cap if
