Specification

Description

This crankshaft gear with part number 2W-0496 is a core transmission accessory compatible with C-16 and C18 series excavator engines. As a vital component of the engine timing transmission system, it accurately transmits crankshaft power and synchronizes the operation of various engine mechanisms to ensure coordinated and stable performance of air distribution, fuel injection and other systems. Manufactured in accordance with original process specifications, it features installation dimensions perfectly matching the designated models for direct replacement of original faulty parts, widely applied to the powertrain of construction machinery excavators.

Advantage

Precisely processed by CNC equipment with strictly controlled dimensional tolerances for gear profile, inner bore and positioning holes, which guarantees high fitting accuracy, allows direct installation without secondary machining and simplifies replacement operation.
Forged from high-strength alloy steel and treated with multiple heat treatments including carburizing quenching and tempering, it achieves high surface hardness and excellent core toughness to resist impact and gear tooth breakage.
Adopting the same structural design as original parts, the lightweight porous structure reduces operating load while optimizing heat dissipation, preventing thermal deformation during long-term high-speed operation.
Each gear undergoes dynamic balance and tooth surface fatigue wear tests before delivery, delivering smooth running with low vibration and transmission noise, effectively extending the service life of the entire timing transmission assembly.

Performance

Excellent Transmission Precision: Adopting high-precision involute gear design with even meshing clearance and low power transmission loss, it ensures accurate engine timing phase, preventing power reduction, higher fuel consumption and engine shaking caused by timing deviation.
Superior Wear Resistance: The precisely ground gear surface withstands heavy alternating loads. It resists tooth surface abrasion, pitting corrosion and slipping even under harsh construction site conditions featuring heavy loads, high temperature and dense dust.
High Thermal Stability: The premium material maintains stable structural dimensions under continuous high-load operating temperature, consistently retaining reliable transmission fitting accuracy without thermal deformation.
Optimized Dynamic Balance: Strict dynamic balance calibration is conducted during production to minimize vibration at high rotating speed, reducing wear on shaft components and avoiding secondary failures such as oil seal leakage and abnormal bearing damage caused by unbalanced transmission.
