A closer look at the heart of industrial performance.

In the world of heavy machinery, the performance of an engine is not a matter of chance; it's a testament to the quality of its components. At the core of some of Caterpillar's most legendary engines—the "3406, 3408, and 3412 series"—lies a critical component that ensures power, efficiency, and longevity: the "Piston with Pin, part number 9Y4004".

Guangzhou Pinxin Engine Co., Ltd. understands that for engine builders and maintenance professionals, choosing the right parts is the difference between smooth operation and costly downtime. The "Caterpillar 9Y4004 Piston with Pin" is more than just a piece of metal; it’s a precision-engineered component designed to withstand the immense pressures and temperatures of a diesel engine's combustion cycle. Its robust construction and precise fit are essential for maintaining proper compression and preventing wear on the cylinder liner.

Why the 9Y4004 Piston Stands Out

The "9Y4004" is specifically engineered to meet the demanding specifications of the 3400 series. This family of engines is renowned for its reliability and power, serving in everything from generator sets and marine vessels to heavy-duty trucks and earthmoving equipment. A high-quality piston like the "9Y4004" ensures the engine maintains its original performance characteristics, providing consistent power output and fuel efficiency. Using an inferior piston can lead to a host of problems, including reduced compression, increased oil consumption, and even catastrophic engine failure.
