FAQ

Q: Is this a complete cylinder head assembly? Does it include valves and springs?

A: This is a bare cylinder head casting. It typically includes pre-installed valve guides and valve seats, but does not include valves, springs, retainers, or the camshaft. You must transfer these components from your old head or purchase a new valve train kit.

Q: How can I confirm this head fits my specific excavator model?

A: The most reliable method is to check the engine nameplate on your machine. The engine model must be a Toyota 3Z. Cross-reference your existing cylinder head’s casting number with our OEM numbers (11101-78102 or 11101-78103). If your casting number matches, it will fit.

Q: What is the recommended installation procedure for this cylinder head?

A: Always use a new head gasket and cylinder head bolts (stretch bolts must be replaced). Clean the block surface thoroughly. Tighten the head bolts in the manufacturer’s specified sequence and torque settings (typically a multi-step torque-angle procedure). Consult the factory service manual for your specific engine for exact values. Failure to follow correct procedures can lead to gasket failure.
