FAQ

Q1: Is this piston compatible with all Yanmar 4TNV94FHT engines?
This piston is designed to OEM size specifications for the 4TNV94FHT engine model. However, engine configurations can vary by application (e.g., marine vs. industrial). We recommend comparing your original piston’s dimensions (diameter, pin height, ring groove configuration) with our specifications. Contact our technical support with your engine serial number for fitment confirmation.

Q2: Does the piston come with rings, or do I need to order them separately?
This product includes the piston and pin only. Piston rings are typically sold separately. For a complete overhaul, we recommend ordering a matching set of piston rings and cylinder liners for the 4TNV94FHT engine to ensure proper sealing and performance.

Q3: What is the expected installation procedure for this piston?
Installation should be performed by a qualified diesel mechanic. Standard procedures include: cleaning the cylinder bore, lubricating the piston and rings, compressing the rings using a ring compressor, and carefully inserting the piston into the cylinder. Ensure the arrow or marking on the piston crown faces the correct direction (usually toward the fuel injection pump or front of the engine). Torque the connecting rod bolts to the manufacturer’s specifications.
