FAQ

Q1: How can I confirm this cylinder head fits my Caterpillar 320D excavator?

A: Please verify your engine serial number and check the existing part number on your current cylinder head. This part replaces OEM numbers 297-7644 and 294-1682, which are specifically designed for the C6.4 engine used in 320D excavators. If your engine is a C6.4 and your existing part matches these numbers, this cylinder head will be compatible. We recommend consulting your equipment’s parts manual for confirmation.

Q2: Does this cylinder head come with valves, springs, and other components installed?

A: This listing is for the cylinder head casting assembly. It typically includes valve guides and seats pre-installed. However, valves, springs, retainers, and other valvetrain components are usually sold separately. Please check the product specifications or contact us for details on what is included with your specific order. We can also provide complete assemblies upon request.

Q3: What maintenance should I perform when replacing the cylinder head on a C6.4 engine?

A: When replacing the cylinder head, we recommend the following: 1) Always use a new cylinder head gasket and head bolts (stretch bolts must be replaced). 2) Check the engine block deck surface for flatness and cleanliness. 3) Inspect the cylinder liners for wear or damage. 4) Follow the manufacturer’s torque sequence and specifications precisely. 5) After installation, perform a cold valve adjustment according to C6.4 specifications. Proper break-in procedures should be followed to ensure long service life.
