Installation Notes
Professional installation is highly recommended. Always consult your engine's service manual for detailed procedures, torque specifications, and safety precautions. Ensure all mating surfaces are meticulously cleaned of old gasket material, oil, and debris before installing new gaskets.
Important: The current OEM replacement kit (729573-92606) does not include the Gasket Liquid (Yanmar P/N 977770-1207F). This sealant must be purchased separately to complete the installation as per factory specifications.
Troubleshooting & FAQ
How do I confirm this gasket set will fit my Yanmar engine?
This set is specifically for the Yanmar 4JH2 series. Please refer to the "Engine & Model Compatibility" table and cross-reference your exact engine model (e.g., 4JH2-TE, 4JH2-DTE) to ensure a perfect match.
Is this a complete kit for a full engine overhaul?
This kit contains the head gasket and all major gaskets required for a typical engine rebuild. However, you should always compare the contents list with the requirements in your engine’s official service manual. Note that the liquid gasket/sealant must be sourced separately.
What is the difference between part 729573-92605 and 729573-92606?
Part number 729573-92606 is the current, active part number from Yanmar, which replaced the older, superseded 729573-92605. The primary difference is that the newer kit (729573-92606) does not include the liquid gasket.
What are common signs my engine gaskets are failing?
Symptoms of a failed gasket can include engine overheating, visible coolant or oil leaks from the engine block or head, loss of compression, milky-white engine oil, or excessive white smoke from the exhaust, which may indicate coolant is burning in the combustion chamber.
