Replace:
Thrust, Main and Rod Bearings, Valve Rotators, Thermostat and Throttle Position SensorIn most probability, these components will not last until the second overhaul. Therefore, Caterpillar recommends the installation of these components new at each overhaul period.Inspect:
Crankshaft, Camshaft, Camshaft Followers, Vibration Damper, Spacer Block, Oil Pump and Fuel Transfer PumpThe ideal time for inspecting your crankshaft, camshaft and vibration damper is while the engine is disassembled for overhaul. Inspect each component for potential damage as follows:Crankshaft - Inspect for bend, journal damage and bearing material seized to the journal. At the same time, check the taper and profile of the crankshaft journals by interpreting your main and rod bearing wear patterns. In case of an out-of-frame overhaul, use the magnetic particle inspection process to check the crankshaft for cracks.* Camshaft - Inspect the camshaft for journal damage. In case of an out-of-frame overhaul, use the magnetic particle inspection process to check the camshaft for cracks.* Camshaft Followers - For out-of-frame overhaul, inspect the cam bearing for fatigue and wear.* Vibration Damper - Inspect the damper for rubber deterioration and movement of the outer ring relative to the inner hub.* Spacer Block - Inspect the spacer block for excessive wear or warping.

Oil Cooler Core and Aftercooler CoreCaterpillar recommends that the oil cooler core and the air-to-air aftercooler core be cleaned and pressure tested at each overhaul. For additional specifications and/or pressure test information, contact your local Caterpillar dealer.Cleaning Procedure for Air-to-Air Aftercooler
Caterpillar recommends that the air-to-air aftercooler core be removed, cleaned, and tested at overhaul time, if a turbocharger failure has occurred, or if at any time the turbocharger develops an oil leak.To clean the air-to-air aftercooler system:1. Remove the air-to-air aftercooler core. Turn the core upside down to remove debris from the inlet tank.
Do not use caustic cleaners to clean the air-to-air aftercooler core. Caustic cleaners will attack the internal metals of the core and cause leakage.
2. Back flush internally with a solvent to loosen foreign substances and to remove oil.Caterpillar recommends the use of Caterpillar Hydrosolv 4165 or Hydrosolv 100 Liquid Cleaners. For more information see "General Instructions and Application Guide" Form LEHQ6101 or contact your Caterpillar dealer.3. Shake the core vigorously to eliminate any trapped debris.4. Wash the core with hot, soapy water. Rinse thoroughly with clean water.
The maximum air pressure must not be above 30 psi (205 kPa) for cleaning purposes.
5. Dry the core with compressed air. Blow air in reverse direction of normal flow. Use all necessary safety equipment while using compressed air.6. Inspect the system to ensure cleanliness and install the air-to-air aftercooler core.Caterpillar Recommendation
The "repair before failure" concept makes sense. It saves money, lowers operating costs and minimizes downtime.As previously illustrated, it is not cheaper to operate the truck until an engine component fails, since failing components may increase fuel costs and upon failure, could
