Description
This product is a piston assembly designed for Perkins N844 series excavator engines (corresponding to model 11501-7581 / 115017581). As a core moving component of the engine, it is responsible for completing key strokes such as compression and power stroke in the cylinder, converting the pressure generated by fuel combustion into mechanical power. Adopting high-precision processing technology, the product strictly matches the original size specifications (such as standard bore size 84.00mm) to ensure precise fit with cylinder liners, piston rings, connecting rods and other components.
Advantage
Precise Fitment: Fully matches the parameters of Perkins N844 engines and model 11501-7581, allowing direct replacement of original parts without modification, reducing installation and commissioning costs.
Durable Material: Made of high-strength aluminum alloy with special heat treatment, it has excellent high-temperature and fatigue resistance, adapting to the high-load and high-speed operating conditions of the engine.
Precision Manufacturing: The key dimensions such as bore, pin hole and ring groove reach the top industry standards, effectively reducing friction loss between the piston and cylinder liner and improving sealing performance.
Stability and Reliability: Optimized inner cavity structure and top combustion chamber design ensure sufficient fuel combustion, while reducing vibration and noise, extending the overall service life of the engine.
Cost-Effective: Provides a more competitive price with quality close to the original factory, making it a cost-effective choice for maintenance and replacement.
Performance
Applicable Models: Perkins N844 series excavator engines, corresponding to model 11501-7581 / 115017581
