Product Introduction

The 3463501739 Crown Wheel and Pinion 18/27 is a key final drive component used in the rear axle differential systems of Mercedes-Benz Actros MP1 / MP2 and MAN TGA / TGM / F2000 heavy-duty trucks.

The crown wheel and pinion gear set is responsible for transferring rotational power from the driveshaft input to the differential assembly and axle shafts. It changes the direction of torque transmission by 90 degrees while providing final gear reduction, allowing heavy-duty vehicles to achieve higher wheel torque, improved traction, and reliable performance under demanding operating conditions.

This gear set consists of an 18-tooth pinion gear and 27-tooth crown wheel, which are precisely matched to maintain correct backlash, tooth contact pattern, and load distribution. Proper gear matching helps reduce drivetrain vibration, minimize operating noise, improve transmission efficiency, and extend the service life of the rear axle system.

During heavy-duty applications, the crown wheel and pinion are continuously exposed to high torque loads, impact forces, and repeated gear contact stress. Gear tooth wear, surface pitting, or incorrect adjustment can lead to abnormal axle noise, overheating, reduced power transmission efficiency, and differential failure.

The 3463501739 crown wheel and pinion set is manufactured using premium alloy steel with advanced production processes including precision forging, CNC gear cutting, carburizing, quenching, precision grinding, and surface hardening. These processes provide excellent tooth strength, fatigue resistance, dimensional accuracy, and long-term durability.

Designed according to OEM specifications, this final drive gear set provides direct replacement compatibility for Mercedes-Benz Actros MP1 / MP2 and MAN TGA / TGM / F2000 rear axle systems. It is widely used for differential overhaul, axle rebuilding, fleet maintenance, and aftermarket drivetrain repair.

Each gear set undergoes strict quality inspections including tooth profile measurement, gear contact pattern testing, hardness verification, backlash inspection, and dimensional control to ensure reliable performance and extended service life.
