For T437131 621-7933 Cylinder Liner Perkins C7.1 C4.4 C6.6 Excavator engine parts

Specification

Description

This is a cylinder liner (matching part numbers T437131/621-7933) designed for specific excavator engine models. Manufactured with high-precision processing technology, it is a core component of the engine block, providing a sealed and wear-resistant working chamber for piston movement, ensuring normal combustion and power output of the engine.

Advantage

Strong Adaptability:Precisely matches the target engine models with high installation fit, no additional adjustment required.
Durable Material:Made of high-wear-resistant alloy material, with excellent corrosion and high-temperature resistance, extending the service life of the component.
Precision Craftsmanship:High-precision inner wall surface treatment reduces piston friction loss and lowers engine operating noise.

Performance

Wear Resistance:The inner wall hardness meets the standard, and the wear amount after long-term use is much lower than industry standards, ensuring stable engine operation.
Sealing Performance:Precise fitting clearance with piston and cylinder block effectively prevents gas leakage and oil 窜入 the combustion chamber.
Heat Resistance:Can adapt to the high-temperature environment of the engine under high-load conditions, with no obvious attenuation of physical properties.
