Product Introduction

This is a heavy-duty right output shaft assembly for the 10-speed HW19710 transmission, engineered for higher torque and longer service life under severe conditions.

• Material & Forging: Monoblock forging from high-strength 20CrMnTi carburized alloy steelfor superior torsional rigidity and impact resistance.

• Preassembled Components: Integrated 3rd (28-tooth, module 3.25) and 4th (32-tooth, module 3.0) gears, heavy-duty needle roller bearings (GCr15), and precision-ground support journals.

• Heat Treatment: Full carburizing, quenching, and precision grinding on gear teeth achieve surface hardness HRC 58–62(anti-pitting/wear) and core hardness HRC 33–45 (anti-fracture). The shaft undergoes highfrequency quenching for wear resistance.

• Spline & Interface: 16-tooth external spline (φ50 mm) at the axle end for secure differential engagement.

Core Function

1. Transmits high-torque power from the countershaft to the right drive axle for 35t–45t loads.

2. Delivers torque via 3rd/4th gears for efficient medium-to-high-speed operation.

3. Connects to the differential via the 16-tooth spline to drive the right wheel.

4. Maintains concentric shaft alignment with preassembled heavy-duty bearings, reducing runout and noise.

Frequently Asked Questions – Output Shaft Assy (Right) AZ2203030210

What is the function of the Output Shaft Assy (Right) AZ2203030210 in the HW gearbox?

The output shaft assembly serves as the primary torque transfer component on the right side of the SINOTRUK HW series gearbox. It transmits rotational power from the transmission gear train to the right-side drive axle, enabling the vehicle to move forward or in reverse. A worn or damaged output shaft can lead to gear slippage, abnormal noise, or complete drivetrain failure.

How do I confirm that AZ2203030210 is compatible with my specific gearbox model?

The AZ2203030210 is designed to fit SINOTRUK HW series gearboxes including HW19710, HW19712, HW15710, and related variants. To confirm compatibility, cross-reference your existing part number on the old shaft assembly or check the nameplate on your gearbox housing. If you’re still uncertain, feel free to send us your VIN or gearbox model number and our technical team will verify fitment for you.

What causes the right output shaft assembly to fail prematurely?

Common causes of premature failure include insufficient lubrication within the gearbox housing, overloading beyond rated torque capacity, contaminated transmission oil, and improper installation alignment. Additionally, using non-OEM parts with incorrect heat treatment or dimensional tolerances can accelerate spline wear and bearing seat damage on the output shaft.

Is the AZ2203030210 output shaft sold as a complete assembly or individual components?

We supply the AZ2203030210 as a complete right output shaft assembly, which typically includes the shaft body, bearing journals, and associated splines as a ready-to-install unit. This saves you the time and complexity of sourcing individual sub-components and ensures dimensional consistency across all mating surfaces.

What is the expected service life of this output shaft assembly?

Under normal operating conditions—with proper lubrication, regular oil changes, and loads within rated capacity—the Output Shaft Assy (Right) AZ2203030210 can reliably perform for 300,000 to 500,000 kilometers. However, service life varies based on operating terrain, payload frequency, and maintenance practices.
