380301706 Front Axle Final Drive Hub Gear for XCMG GR135 Motor Grader

Product Introduction

The 380301706 is a dedicated final drive hub gear for the front steering drive axle of XCMG GR series motor graders. It installs inside the wheel hub reduction unit, meshing with planetary gears to deliver reduced speed and amplified torque from the axle shaft to the wheel hub. This part is engineered to match original equipment specifications for direct fit replacement on GR135 graders.

Material & Build Quality

Made from premium alloy steel, this gear goes through full carburizing and quenching heat treatment to create a hard, wear-resistant tooth surface while retaining a tough, impact-resistant core. All tooth profiles are finish-ground to tight tolerances, ensuring smooth engagement, minimal running noise and long service life even under continuous heavy grading loads on construction and road maintenance sites.

Core Advantages

• 1:1 OEM dimensional specification – direct bolt-on replacement with no machining required

• High torsional load capacity built for heavy-duty grader operations and tough job site conditions

• Precision machined internal spline and flange holes guarantee concentric mounting and stable power transfer

• Uniform surface hardness reduces wear on mating planetary gears, extending the service life of the whole wheel reduction set

• Rust-proof surface treatment for protection during transit and long-term storage

Compatibility Notes

This gear is factory-matched for the front axle of XCMG GR135 motor graders, and is also interchangeable with front axle wheel reduction gears on GR165 models that share the same axle platform. Always confirm your grader model and original part number before placing an order to ensure correct fitment.
