Specification

Description

This rear idler gear with part number 2W-0493 is designed for C-16 and C18 series excavator engines, serving as a core component of the engine timing transmission system. It is manufactured via precise integrated forging and high-precision gear hobbing processes in strict accordance with original dimensional standards. The gear can directly replace worn, damaged or broken original idler gears at the original mounting position. It connects the engine timing transmission structure stably to ensure accurate synchronous operation of the engine valve train, and is widely applied in engine maintenance, repair and refitting of construction machinery equipment of the same series.

Advantage

Adopts high-precision gear profile processing with uniform and wear-resistant tooth surface, effectively preventing tooth surface abrasion, tooth breakage and gear jumping during long-term high-speed operation, greatly extending service life.
Strictly copies original installation dimensions. The central mounting position, fixing holes and positioning holes are perfectly matched without modification or processing, which simplifies installation and disassembly and cuts maintenance labor time and cost.
Made of high-strength alloy steel with quenching and tempering as well as carburizing heat treatment, the gear features excellent deformation resistance and impact resistance, adapting to harsh working conditions such as high temperature, heavy load and long-time continuous operation on construction sites.
Each gear is inspected and calibrated for dynamic balance before delivery, delivering low vibration and noise during high-speed rotation. It avoids timing deviation and abnormal noise caused by unbalanced gears, thus protecting peripheral key parts including crankshaft and camshaft.

Performance

Excellent transmission stability: Precisely meshes with matched transmission gears to guarantee synchronous operation of the engine timing system, preventing failures such as insufficient power, engine knocking, hard starting and valve bending caused by timing misalignment.
High temperature and fatigue resistance: Heat-treated gears operate steadily under long-time high-temperature engine conditions, resisting metal fatigue and deformation during repeated high-speed cyclic operation to maintain stable transmission performance continuously.
Outstanding heavy-load impact resistance: Withstands instantaneous torque impact under full-load operation of construction machinery, keeping the transmission system stable even under bumpy and high-intensity working scenarios.
Good sealing and fitting performance: The finely ground central shaft bore fits tightly with matched shaft sleeves and bearings to retain lubricating grease efficiently, reducing dry friction loss and slowing down component wear.
