How do I identify the correct parts for my Yanmar engine?
To find the correct replacement parts for a Yanmar diesel engine, you’ll need the engine model number (such as 3TNV88, 4TNV98C, or 4TNE106), the engine serial number located on the engine data plate, and the part number from the failed or worn component if one is available. Yanmar engine model and serial number plates are typically affixed to the side of the engine block. The engine model will tell you the cylinder count and general series, while the serial number allows for more precise part matching within a model family. With that information, browse the HHP Yanmar catalog by part category or search by part number.
