Product Overview

This piston & piston ring set Part No.6217‑31‑2130 is an indispensable core power component specially designed for Komatsu 6D140E‑3 diesel engine. It converts high‑pressure combustion energy into mechanical power to drive crankshaft rotation. The matched piston rings form a reliable sealing barrier inside cylinder liner, preventing combustion gas leakage, controlling oil consumption and avoiding burning‑oil failure. Our aftermarket piston set is strictly manufactured according to OEM specifications, adopting high‑strength cast‑alloy material with outstanding high‑temperature resistance, wear‑resistance and thermal‑deformation resistance. It can run stably under long‑time heavy‑load mining and construction conditions, and serves as a perfect replacement spare part for Komatsu engine overhaul and maintenance.
