800167203 rocker arm shaft XCMG XE2000 excavator spare parts

XCMG XE2000 excavator rocker arm shaft (part number 800167203) – the core power transmitter of the engine valve train system!

Military-grade materials precisely adapted

The rocker arm shaft (800167203), specifically designed for the XE2000 engine, is made of high-strength alloy steel (20CrMnTi) through a carburizing and quenching process, achieving a surface hardness of HRC58-62 while maintaining core toughness. Precision grinding ensures the shaft diameter tolerance is controlled within ±0.005mm, guaranteeing zero resistance in rocker arm movement and extending the life of the valve train system.

Five major technological breakthroughs

🔧 Hollow design for weight reduction: 30% weight reduction, decreased inertial force
⚡ Ultra-precision grinding process: Surface roughness Ra≤0.1μm, friction coefficient reduced by 50%
🔥 Deep carburizing treatment: Carburized layer depth 1.2-1.5mm, wear resistance increased by 3 times.
💧 Axial oil passage optimization: Lubricating oil flow increased by 40%
🛡️ Anti-fretting wear coating: Resists fretting wear for up to 8000 hours.
