FAQ

Q1: Is the Yanmar 129601-11700 cylinder head a direct bolt-on replacement for the 4TNV88 engine? Do I need any additional parts?

Yes, this cylinder head is a direct bolt-on replacement. However, we recommend replacing the cylinder head gasket (OEM # 119-512-10000), head bolts, and valve stem seals simultaneously to ensure a proper seal and prevent future leaks. The head does not come with valves or springs pre-installed; you must transfer your existing valve train components or purchase a new set.

Q2: What is the maximum operating temperature this cylinder head can handle in a turbocharged 4TNV88T engine?

The cast iron material used in this head is rated for continuous operation up to 400°C (752°F) at the exhaust valve bridge area. For turbocharged applications (4TNV88T), ensure your cooling system is in good condition and that you use a high-quality coolant. The head is designed to handle the increased thermal load of turbocharging without warping, provided the engine is not overheated.

Q3: How can I verify that this cylinder head will fit my specific Yanmar excavator model (e.g., VIO30)?

To confirm fitment, locate the engine serial number on your 4TNV88 engine (stamped on the engine block near the fuel injection pump). Cross-reference this with the part number 129601-11700. While this head fits most 4TNV88 engines from 2005 onward, some early models may require a different head casting (129601-11600). We recommend sending us a photo of your old cylinder head’s casting number for verification before ordering.
