Product Introduction

The 3463531914 Differential Spider Side Pinion is a key internal gear component used in the rear axle differential assemblies of Mercedes-Benz Actros MP1 / MP2 and MAN TGA / TGM / F2000 heavy-duty trucks.

The differential side pinion is installed inside the differential carrier and works together with the spider shaft, spider gears, side gears, and thrust washers to transfer torque and compensate for different wheel speeds when the vehicle turns. This gear structure allows the left and right wheels to rotate at different speeds while maintaining stable power transmission.

During heavy-duty operation, the side pinion is subjected to continuous gear contact pressure, high torque loads, vibration, and impact forces. Excessive wear, tooth damage, or incorrect clearance may cause differential noise, increased backlash, uneven gear operation, and accelerated wear of related axle components.

The 3463531914 side pinion gear is manufactured from premium alloy steel using precision forging, CNC gear machining, heat treatment, and surface hardening technology. The hardened tooth surface improves fatigue strength, wear resistance, and load-bearing capability, ensuring reliable operation under heavy truck working conditions.

Designed according to OEM specifications, this differential side pinion provides direct replacement compatibility for Mercedes-Benz Actros MP1 / MP2 and MAN TGA / TGM / F2000 rear axle differential systems. It is widely used for differential repair kits, axle rebuilding, commercial fleet maintenance, and aftermarket drivetrain servicing.

Each gear undergoes strict quality inspections including tooth profile testing, hardness inspection, dimensional verification, and fitment testing to ensure precise engagement and extended service life.
