FAQ

Q: How do I know if this 4TN86 piston ring set fits my engine?
A: This set is specifically designed for the Yanmar 4TN86 diesel engine. Please verify your engine model by checking the data plate on your engine block. It is commonly used in forklifts and excavators. If your engine is a 4TN86, this set is the correct size (OEM size).

Q: Does this set include all the rings needed for one piston or all four pistons?
A: This listing is for a complete set of piston rings for the 4TN86 engine, which typically covers all four (4) cylinders. Please confirm with the supplier if you require a single piston set or a full engine set before ordering.

Q: What is the recommended installation procedure?
A: Professional installation is recommended. Ensure the cylinder bore is honed to spec and cleaned. Install rings using a ring expander tool, staggering the ring gaps (typically 120 degrees apart) to prevent compression loss. Lubricate with clean engine oil during assembly. Always refer to the Yanmar service manual for your specific engine model.
