Product Introduction

The 3463504139 Crown Wheel and Pinion / Ring Gear and Pinion Set is a critical drivetrain component used in the final drive differential system of Mercedes-Benz and MAN heavy-duty trucks. It consists of a matched ring gear and pinion gear set, responsible for transferring power from the drive shaft to the axle shafts while reducing speed and increasing torque output.

The crown wheel and pinion gear set determines the final drive ratio of the axle system. The pinion gear receives rotational force from the propeller shaft and transfers it to the crown wheel, changing the direction of power transmission and providing the necessary torque multiplication for heavy-duty vehicle operation.

During continuous operation, this gear set is exposed to high torque loads, repeated gear meshing, impact forces, and changing road conditions. Gear tooth wear, pitting, incorrect backlash, or insufficient lubrication may result in abnormal noise, vibration, overheating, and reduced drivetrain efficiency.

The 3463504139 ring gear and pinion set is manufactured from high-strength alloy steel with precision forging, CNC machining, gear grinding, and heat treatment processes. The accurate tooth profile and matched gear design ensure smooth engagement, low operating noise, excellent fatigue resistance, and extended service life.

Designed according to OEM specifications, this crown wheel and pinion set provides reliable replacement compatibility for Mercedes-Benz Actros, Axor, NG, SK, Econic, North Benz, and MAN truck axle systems. It is widely used for rear axle rebuilding, differential overhaul, fleet maintenance, and aftermarket drivetrain repair applications.

Each gear set undergoes strict quality inspection including tooth profile testing, hardness inspection, backlash verification, dimensional measurement, and gear matching inspection to ensure reliable operation and OEM-level performance.
