Product Introduction

The 3463541717 Sun Gear is a key component of the planetary wheel reduction system used in Mercedes-Benz Actros MP1 and MP2 heavy-duty trucks. It is installed inside the wheel hub reduction assembly and meshes with planetary gears to transmit torque from the axle shaft to the wheels while improving load distribution and driving efficiency.

Manufactured from premium alloy steel with precision forging, CNC gear machining, and heat treatment, this sun gear delivers excellent tooth strength, impact resistance, and wear durability. The accurate gear profile ensures smooth engagement with planetary gears, reducing noise, vibration, and abnormal wear during operation.

Designed according to OEM specifications, this sun gear provides direct replacement compatibility with original Mercedes-Benz HL7 rear axle hub reduction assemblies. It is widely used for axle rebuilding, wheel reduction repair, fleet maintenance, and aftermarket replacement applications.

Each unit undergoes strict quality inspections including gear tooth accuracy testing, hardness inspection, dimensional verification, and surface finish checking to ensure reliable performance under heavy-duty working conditions.
