Battery Electrolyte Level - Check

Steps to check the battery electrolyte level

Refer to Engine Systems Operation/Testing and Adjusting in order to perform the complete procedure for the valve lash adjustment.

Steps to check the final drive oil level

Warning: Personal injury can result from hot coolant, steam and alkali.

At operating temperature, engine coolant is hot and under pressure. Any contact can cause severe burns.

Remove cooling system pressure cap slowly to relieve pressure only when engine is stopped and cooling system pressure cap is cool enough to touch with your bare hand.

Do not attempt to tighten hose connections when the coolant is hot, the hose can come off causing burns.

Cooling System Coolant Additive contains alkali. Avoid contact with skin and eyes.

Use Caterpillar Extended Life Coolant (ELC) when you add coolant to the cooling system.

Mixing ELC with other products will reduce the effectiveness of the coolant. This could result in damage to cooling system components.

If Caterpillar products are not available and commercial products must be used, make sure they have passed the Caterpillar EC-1 specification for premixed or concentrate coolants and Caterpillar Extender.

Note: This machine was filled at the factory with Caterpillar Extended Life Coolant.

Air Conditioner/Cab Heater Filter (Recirculation) - Inspect/Replace

An air recirculation filter element plugged with dust will result in decreased performance and service life to the air conditioner or cab heater.

To prevent decreased performance, clean the filter element, as required.

The air conditioner filter is located on the lower left side of the cab behind the seat.

1. Slide the operator seat forward.

2. Slide the filter element upward.

3. Tap the air filter against the palm of one’s hand in order to remove the dirt. Do not use compressed air to clean the filter.

4. After you clean the filter element, inspect the filter element. If the filter element is damaged or badly contaminated, use a new filter element. Make sure that the filter element is dry.

Your engine is equipped with a water pump, with a fan drive, and with an alternator. Your engine can also be equipped with an air conditioner belt. For maximum engine performance and maximum utilization of your engine, inspect the belts for wear and for cracking. Check the belt tension. Adjust the belt tension in order to minimize belt slippage. Belt slippage will decrease the belt life. Belt slippage will also cause poor performance of the alternator and of any driven equipment.

If new belts are installed, recheck the belt adjustment after 30 minutes of operation. If two belts or more are required for an application, replace the belts in belt sets. If only one belt of a matched set is replaced, the new belt will carry more load. This is due to the fact that the older belts are stretched. The additional load on the new belt could cause the new belt to break. Water Pump Belt, Fan Drive Belt, and Alternator Belt

2. Inspect the condition of the serpentine belt. Over time the belt ribs will lose material (C). The space between the ribs will increase (D). The loss of material will cause the pulley sheave to contact the belt valley. This will lead to belt slippage and accelerated wear (E). Replace the belt if the belt is worn or frayed.

3. Apply approximately 98 N (22 lb) force midway between the pulleys.

4. Measure the deflection of the belt. The belt should deflect 10 to 12 mm (0.4 to 0.5 inch).

5. If the deflection is not correct, loosen alternator mounting bolt (1) and bracket bolt (2). Turn adjusting bolt (3) in order to adjust the belt tension.

6. When the adjustment is correct, tighten bolt (1) and bolt (2).
