Product Introduction

The 3463502839 Crown Wheel and Pinion 15×29 is a critical final drive gear set used in the rear axle assemblies of Mercedes-Benz Actros, Axor, and MAN heavy-duty trucks. It consists of a precision-matched 15-tooth drive pinion and 29-tooth crown wheel, engineered to provide efficient torque multiplication and dependable power transmission from the driveshaft to the axle shafts.

The crown wheel and pinion convert the longitudinal rotation of the propeller shaft into transverse rotation of the differential while increasing torque to meet the heavy-load demands of commercial trucks. Accurate gear tooth geometry and factory-matched gear pairing ensure smooth power delivery, reduced vibration, minimal operating noise, and improved drivetrain efficiency.

During continuous heavy-duty operation, the gear set is subjected to high torque, shock loading, and continuous gear contact. Excessive wear, pitting, improper gear contact, or lubrication failure can result in abnormal noise, overheating, reduced transmission efficiency, and eventual axle failure.

The 3463502839 gear set is manufactured from premium alloy steel using precision forging, CNC gear cutting, carburizing, quenching, and precision lapping processes. Each crown wheel and pinion are factory-matched to ensure optimal contact patterns, accurate backlash, and long-term durability.

Designed according to OEM specifications, this final drive gear set offers direct replacement compatibility for Mercedes-Benz Actros MP1 / MP2, Axor, and MAN TGA / TGM axle systems. It is widely used for differential rebuilding, rear axle overhaul, commercial fleet maintenance, and aftermarket drivetrain repair.

Every gear set undergoes strict OEM-quality inspections including gear ratio verification, tooth contact pattern testing, hardness testing, dimensional measurement, and noise performance evaluation to ensure dependable operation and maximum service life.
