CNC Precision Machining High-Strength Alloy Steel Engine Gear Drive Gear Assembly with Integral Forging Technology

Engine Gear For 187-8202 1878202 Drive Gear Assembly CAT C18 Excavator engine parts

Specification

Description

This drive gear assembly with part number 187-8202 is a transmission accessory of OEM standard suitable for C18 series excavator engines. It is manufactured through integrated forging technology with precise dimensions matching the internal transmission assembly of the engine. Designed with an internal multi-spline bore, high-precision external gear teeth and standard positioning mounting holes, it can directly replace the original faulty gear. This component is applied to torque transmission of the engine power system to ensure stable operation of engine timing and power transmission structures, widely used in power assemblies of construction machinery excavators of corresponding models.

Advantage

Adopts CNC precision machining with strictly controlled gear tooth tolerance and even meshing clearance. No secondary grinding is required during installation, which features easy assembly and perfect fit for original mounting positions.
Made of high-strength alloy steel with dual heat treatment including quenching and tempering as well as carburizing quenching. It owns high surface hardness and excellent core toughness, featuring outstanding impact resistance and wear resistance to withstand repeated meshing operation under heavy-load working conditions for a long time.
Integrated precision forging structure eliminates hidden dangers of splicing and welding. The internal spline and gear body are integrally formed, effectively preventing common failures such as keyway cracking, gear fracture and tooth slipping under heavy load, greatly reducing equipment maintenance frequency.
Each gear passes dynamic balance calibration and fatigue life test before delivery. Its dimensions are fully consistent with OEM specifications, featuring strong versatility for replacement of all engine models of the corresponding series.

Performance

Stable Transmission Performance: Adopting high-precision involute tooth profile, the gear realizes smooth meshing, low operating noise and slight vibration. It can transmit engine torque stably and efficiently and reduce power transmission loss.
Excellent Wear and Fatigue Resistance: The gear surface undergoes professional hardening treatment, effectively avoiding tooth surface pitting, abrasion and tooth breakage under long-term high-speed and heavy-duty operation, with much longer service life than ordinary alternative spare parts.
High Temperature and Deformation Resistance: Premium alloy steel can adapt to the high-temperature working environment inside the engine compartment. Thermal deformation will not occur during continuous operation to keep standard transmission clearance and prevent timing deviation and gear jumping failures.
Strong Load-bearing Capacity: The internal multi-spline structure bears force evenly to resist high-torque impact loads. It works reliably under harsh working conditions such as heavy load and intermittent start-stop of construction machinery, ensuring long-term stable operation of the engine transmission system.
