Engine gear For 2W-0494 2W0494 Rear Idler Gear CAT C-16 C18 Excavator Engine Parts

Specification

Description

This rear idler gear with part number 2W-0494 is specially designed and matched for C-16 and C18 series excavator engines, serving as a core component of the engine timing transmission system. Designed with standard gear teeth, 3 mounting holes and high-precision inner bore sleeve structure, it strictly complies with original installation dimensions. It is mainly applied for timing power transmission inside the engine, stably transmitting operating torque and balancing the rotating speed of the timing system, to ensure synchronous and accurate operation of the engine valve train and fuel injection system, suitable for heavy-duty working conditions of high-power construction machinery excavator engines.

Advantage

Manufactured by original-equipment-level precision forging, it follows strict OEM dimensional tolerance standards. Direct replacement installation without modification ensures perfect fitting and avoids abnormal clearance or meshing dislocation.
Made of high-strength alloy steel with multiple heat treatment processes, the gear surface features excellent wear resistance and impact resistance, resisting high-temperature deformation under long-term high-load and frequent meshing working conditions.
The inner bore adopts precision honing process with high coaxiality and limit groove design, effectively preventing axial displacement during operation, reducing abnormal wear of gears, shaft sleeves and bearings, and extending the service life of the whole transmission assembly.
Protected with anti-rust oil before delivery, the gear avoids rust during storage and transportation, and can be directly installed to adapt to various harsh working environments of construction machinery.

Performance

Excellent transmission stability: Adopting high-precision involute tooth profile machining, the gear achieves smooth meshing and low operating vibration, which effectively reduces transmission noise at idle speed and high engine speed, and prevents timing jumping and valve timing disorder failures.
Superior fatigue resistance: Treated with overall quenching and tempering plus surface hardening, the gear has outstanding tensile strength and anti-fatigue performance. It can withstand continuous high torque output of high-power engines without tooth breakage, surface pitting or slipping wear.
Stable dimensional accuracy: Strictly controlled coaxiality of inner bore, mounting holes and gear rim guarantees reliable dynamic balance at high rotating speed, lowering extra load of the transmission system and the failure rate of engine accessories.
Strong environmental adaptability: It works stably under high temperature, greasy and dusty conditions in engine compartments, maintaining consistent transmission performance during long-time heavy-duty continuous operation to guarantee long-term reliable engine operation.
