6042533300 / 60425-33300 Transmission Shaft for Mitsubishi Motor Graders

The 6042533300 / 60425-33300 transmission shaft is a critical internal drivetrain component designed for Mitsubishi motor graders, especially MG-series platforms such as the MG530. This precision-machined shaft plays a central role in transferring rotational force through multiple gear stages, allowing smooth power distribution inside the gearbox.

Manufactured from high-strength alloy steel and treated for surface durability, this part is engineered to operate reliably under continuous load, vibration, and torque fluctuation—common conditions in grading, quarrying, and mining environments.

At 3GEN Export, we supply this component as an OEM-grade replacement and deliver worldwide within 5 working days, helping operators minimize downtime and keep equipment productive.

Product Overview

This multi-stage gearbox shaft integrates several gear sections into a single balanced assembly. Each spline and gear surface is machined with tight tolerances to ensure accurate meshing and consistent torque flow.

Its design supports:

• Stable transmission performance

• Reduced vibration at operating RPM

• Even load distribution across gear teeth

• Long-term resistance to torsional fatigue

Because this shaft directly interfaces with multiple drivetrain elements, dimensional accuracy is essential for protecting bearings, housings, and mating gears.

Function Inside the Transmission System

Inside the grader gearbox, this shaft acts as a main carrier for rotational energy. Engine power is routed through the transmission, where this component coordinates speed ratios and torque output across connected gears.

Any wear or deformation in this area can lead to:

• Irregular shifting

• Gear noise

• Increased oil contamination

• Accelerated bearing damage

Replacing worn drivetrain shafts early prevents cascading failures and costly rebuilds.
