Technical Specifications for C9 ACERT Casting

Technician’s Note: Installation & Inspection

Technician’s Note: The C9 engine utilizes a HEUI fuel system where fuel pressure is critical. When installing this head, verify that the injector sleeves (cups) are perfectly sealed. Our heads come with sleeves pre-installed, but we strongly advise pressure testing the coolant passages before final assembly to ensure no o-ring damage occurred during shipping.

Technical FAQ: Caterpillar C9 Cylinder Head

How do I verify if this head fits my C9?

The most accurate way is to check the casting number on your old cylinder head. This part (332-3619) corresponds to casting number 3117226 or 311-7226. It is found on the side of the head. If your casting number matches, this is the correct replacement.

Does this head work on Marine C9 engines?

Marine C9 engines often use different cooling configurations. While the core casting might be similar, we recommend providing your engine serial number (e.g., C9B prefix) to confirm if part number 332-3619 is compatible with your specific marine application.

Are the valves adjustable on this head?

Yes, but you must follow the specific Caterpillar C9 ACERT lash adjustment procedure. This head uses a bridge system for the valves. Ensure bridges are balanced before setting the final valve lash to prevent premature wear.
