FAQ

Q: How can I confirm this cylinder head will fit my specific Yanmar 4TNE88 engine?
A: The most reliable method is to cross-reference the part number. This head replaces OEM number 129407-11700. Check the casting or part number on your original cylinder head or consult your engine’s service manual for the correct part number. The 4TNE88 engine model must match.

Q: Is this a complete cylinder head assembly, or does it come without valves and springs?
A: The product listing indicates this is a Cylinder Head as a single item. Typically, this refers to the cast head with machined surfaces and valve guides/seats installed. Valves, springs, rocker arms, and injector sleeves are usually not included unless specified. Please inquire for clarification on the exact configuration before ordering for a major overhaul.

Q: What are the recommended installation checks when fitting this new cylinder head?
A: Prior to installation, we recommend: 1) Checking the head for any shipping damage. 2) Verifying the flatness of the head and block mating surfaces. 3) Ensuring all coolant and oil passages are clean. 4) Using a new head gasket kit and torquing the head bolts to the engine manufacturer’s specified sequence and values. Proper installation is critical for performance and to maintain the warranty.
