This is a complete cylinder head assembly for CAT 3304 and 3306 engines, designed to house the valves and provide the combustion chamber seal. It is manufactured to meet stringent OEM quality standards, ensuring superior durability and performance compared to worn or damaged heads. Operators may notice a loss of engine power, rough idling, or visible exhaust smoke if the cylinder head is compromised.
Always verify with serial number before ordering.

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.
A failing cylinder head may initially present as a slight decrease in engine performance or an increase in oil consumption. If left unaddressed, the issue can progress to persistent rough idling, coolant leaks into the combustion chamber, or exhaust gas contamination of the cooling system. Continued operation with a compromised cylinder head risks severe internal engine damage.
Ensure the engine block deck is perfectly clean and free of any debris or old gasket material before installing the new head. Avoid overtightening the head bolts in a random pattern, as this can lead to uneven clamping force and potential gasket failure.
Always replace the cylinder head gasket when installing a new cylinder head and inspect the engine block deck for flatness.
