178-6512 Camshaft — Cat 320C 320D

This camshaft is a critical component within the engine's valve train, responsible for actuating the intake and exhaust valves at the correct time. Manufactured to precise specifications, it ensures optimal airflow into and out of the combustion chambers, providing better performance than a worn camshaft with flattened lobes. Operators may observe symptoms such as rough idling, reduced engine power, or increased exhaust smoke when this part begins to fail.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Initial signs of a failing camshaft may include irregular engine idling and a noticeable loss of engine power. As wear progresses, valve timing can become significantly compromised, leading to rough running, misfires, and increased fuel consumption. Continued operation with a worn camshaft risks damage to other valve train components and reduced engine efficiency.

Installation Tip

Ensure all oil galleries within the camshaft are thoroughly cleaned and lubricated before installation to prevent initial dry start-up damage. Do not allow the camshaft lobes to contact the lifters before the camshaft is fully seated and timed.

Service Note

When replacing the camshaft, inspect the camshaft bearings, lifters, and timing gears or chain for wear.
