3406 TRUCK ENGINE Caterpillar

Daily Care And Report

Usage:

A daily inspection of the engine should be made to prevent premature engine failure. If corrective steps are taken immediately on discovery of a malfunction, fewer forced stops will be required. This will help obtain the most economical operation. If any abnormal readings or observations are found, be sure to report it. Points to be checked daily are:

1. Oil, air, water or fuel leaks.

2. Cooling system: Clean the radiator core and add coolant or antifreeze as necessary. Be sure the radiator cap seal is in good condition and the cap is installed tightly.

3. Unusual engine noise.

4. Excessive use of crankcase lubricating oil, coolant, battery fluid or fuel.

5. Fuel pressure gauge: Check with the engine running. Change the fuel filter if indicator is in the red range.

6. Air cleaner indicator, if equipped: Inspect with the engine running. Service the air cleaner when the red piston remains in the UP position.

7. Unusual turbocharger noise or vibration: A muffled high pitch whine is the normal sound.

8. Cleanliness: Dirt should not be allowed to accumulate on the engine.
