Product Introduction

This gear is a critical power transmission component in the transmission, engineered for high torque and durability.

• Structure & Material: Manufactured from high-strength 20CrMnTi alloy steel, with precision-machined gear teeth and an integral splined bore for secure engagement with the output shaft.

• Heat Treatment: Full carburizing and quenching processes achieve a surface hardness of HRC 58–62 for wear and pitting resistance, while maintaining a core hardness of HRC 33–45 for impact toughness.

• Precision & Fit: Gear teeth are precision ground to ensure smooth meshing, low noise, and accurate power transfer. The splined bore matches the output shaft interface for zero backlash.

Core Function

1. Power Transfer: Transmits torque from the countershaft to the output shaft at a fixed gear ratio, enabling the vehicle to achieve the corresponding speed and torque output.

2. Durable Operation: Withstands high torque loads and frequent shifting impacts, ensuring long service life under heavy-duty conditions.

3. Smooth Meshing: Precision-machined teeth minimize noise, vibration, and power loss during transmission operation.

Customer Case Study – AZ2210030227 Output Shaft Transmission Gear

A fleet maintenance company based in East Africa manages over 120 SINOTRUK HOWO tipper trucks used in mining operations. After experiencing recurring output shaft transmission gear failures caused by non-genuine replacement parts, their head engineer contacted Mettlead seeking a reliable, OEM-specification source for part number AZ2210030227.

We supplied an initial trial order of 30 units of the Output Shaft Transmission Gear AZ2210030227 for their SINOTRUK HW series gearboxes. Following installation, the client reported a significant reduction in gear noise and zero premature failures over a 6-month monitoring period. Subsequently, they placed a recurring quarterly order and expanded procurement to include additional HW gearbox components such as synchronizer assemblies and counter shaft gears.

This case demonstrates exactly why sourcing genuine-specification gearbox parts matters — inferior metallurgy and imprecise tooth profiles lead to accelerated wear, costly downtime, and repeated overhauls. With Mettlead’s factory-direct supply and strict quality control, their total cost of transmission maintenance dropped measurably.

Frequently Asked Questions – Output Shaft Transmission Gear AZ2210030227

What gearbox models does the AZ2210030227 output shaft transmission gear fit?

The AZ2210030227 output shaft transmission gear is designed for the SINOTRUK HW series gearbox family, including models HW19710, HW15710, HW19712, and HW25712. It fits HOWO, SITRAK, and Steyr-platform trucks that use these transmissions.

What material is this output shaft gear made from?

This transmission gear is forged from carburized alloy steel — typically 20CrMnTi grade — then heat-treated through carburizing, quenching, and tempering to achieve a surface hardness of HRC 58–63. This combination gives you excellent wear resistance on the tooth surface while the tough core absorbs shock loads.

How can I verify that AZ2210030227 is the correct part number for my gearbox?

You can confirm compatibility by checking your original gearbox assembly drawing or the part number stamped on the existing gear. If you are unsure, send us your gearbox model number and VIN, and our technical team will cross-reference the correct output shaft transmission gear for your specific configuration.

What causes premature failure of the output shaft transmission gear in HW gearboxes?

Common causes include contaminated or insufficient gearbox oil, misaligned installation, using non-OEM gears with incorrect tooth profiles, and operating consistently beyond rated load capacity. Installing genuine-spec parts like AZ2210030227 and following SINOTRUK’s recommended oil change intervals significantly extends gear service life.

Does this gear come pre-assembled or as a standalone component?

The AZ2210030227 is supplied as a standalone output shaft transmission gear. It is intended for professional installation during gearbox overhaul or targeted repair. Bearings, seals, and mating components should be inspected and replaced as needed during installation.

Can you supply other HW series gearbox parts along with this gear?

Absolutely. Mettlead stocks a comprehensive inventory of SINOTRUK HW gearbox components including input shafts, counter shafts, synchronizer rings, shift forks, bearing assemblies, and gasket kits. Ordering related parts together saves on shipping and ensures component compatibility.
