For T417298 5042903 3693188 Piston Kit Perkins C7.1  Excavator Engine Parts

Specification

Description

This piston kit is specially fitted for C7.1 series excavator engines, with corresponding part numbers T417298, 5042903 and 3693188. As a core wearable spare part for engines, the complete set consists of piston body, piston rings and other matched accessories. Manufactured in strict accordance with original process standards and original Brazilian specifications, it is formed through precision machining. Fully compatible with engineering machinery engines of matching models, it can directly replace damaged original parts. Widely used in various excavators equipped with this series of engines, it undertakes the core work of mixed gas compression and power transmission inside the engine to ensure stable engine operation.

Advantage

Forged from high-strength aluminum alloy, it resists high-temperature deformation and high-pressure impact, avoiding cracking and piston crown melting during long-term operation.
Adopting CNC precision machining, it features strictly controlled dimensional tolerance with standard STD specification. It fits cylinder liners perfectly with accurate assembly clearance, requiring no secondary grinding and enabling convenient replacement and installation.
Equipped with standard matched piston rings for excellent sealing performance, effectively preventing engine oil blow-by and cylinder air leakage, and reducing failures including engine oil burning and power attenuation.
The surface is treated with wear-resistant and anti-corrosion coating to resist erosion from high-temperature oil and corrosive substances inside the engine, extending service life and cutting later maintenance frequency and operating costs for equipment.
Every piston kit passes strict factory inspections including tightness and pressure stability tests, featuring high universal compatibility to avoid abnormal noise and insufficient power caused by mismatching after installation.

Performance

Excellent high-temperature resistance allows long-term stable operation under high temperature in combustion chambers. The piston crown will not deform or ablate easily, maintaining fixed compression ratio and sufficient engine power output.
Superior compression resistance enables the piston to withstand instantaneous high pressure from cylinder combustion. It maintains stable structural performance under heavy-load and long-time continuous working conditions.
Efficient sealing and lubrication performance realizes precise oil-gas separation in the cylinder, lowering oil consumption, black exhaust emission and high fuel cost, and greatly improving fuel utilization efficiency.
Precisely bored piston pin hole ensures smooth reciprocating movement with low mechanical resistance, effectively reducing internal wear and operating noise of the engine.
Strong environmental adaptability supports stable work under harsh construction conditions such as dusty sites, extreme temperatures and heavy-duty operations.
