Product Parameters

Features of the Yanmar Diesel Engine Piston

The Yanmar Diesel Engine Piston is manufactured from high-strength aluminum alloy. The piston crown, ring grooves, and skirt are precision-machined to match Yanmar 4TNV98 and 4TNE98 engine specifications. The top ring groove receives a reinforced surface treatment for improved wear resistance. The pin bore is honed for consistent contact with the piston pin. These details help maintain cylinder compression and reduce oil consumption in demanding diesel applications.
