This piston assembly includes piston, piston pin and retaining circlips, specially designed for Caterpillar 3406 diesel engines, widely used in heavy-duty excavators, generators and large construction equipment. Made of high-grade aluminum alloy, it features excellent heat dissipation and impact resistance under high temperature and heavy load working conditions. Precision machining ensures proper clearance with cylinder liner, reducing wear and maintaining stable engine power output. Each piston assembly is fully inspected before shipment for reliable performance and simple installation.
