Product Introduction

• Structure: A precision monoblock forging from 20CrMnTi alloy steel, integrating 3rd and 4th speed fixed gears and a precision-ground support journal. The axle end features a 16-tooth external spline for differential engagement. The gear teeth are fully carburized, quenched, and precision-ground, achieving surface hardness HRC 58–62(anti-pitting/wear) and core hardness HRC 33–45 (anti-impact fracture).

• Performance: The monoblock design eliminates gear-shaft assembly gaps, ensuring high torsional rigidity for medium-load operation. The hardened gear surfaces resist wear in frequent shifting scenarios, while the precision journal maintains shaft concentricity, reducing running noise and bearing wear.

Core Function

1. Medium-load power output: Transmits torque from the transmission countershaft to the right drive axle, supporting the load capacity of the HW19710 transmission.

2. Multi-speed torque transfer: The integrated 3rd/4th gears mesh with the countershaft gears to deliver torque across medium-speed driving scenarios.

3. Differential connection: The splined axle end engages with the differential side gear, transferring power to the right drive wheel.

Application Scenarios – Where Does This Output Shaft Fit?

The Output Shaft (Right) AZ2210030215 is designed exclusively for the SINOTRUK HW Series Gearbox, which is widely installed in China’s most popular heavy-duty truck platforms. If your customers operate any of the following vehicles, this part belongs in your inventory:

• SINOTRUK HOWO A7 / T7H / T5G tractor trucks equipped with HW19710 or HW19712 transmissions
• SINOTRUK SITRAK C7H heavy-duty logistics vehicles
• SINOTRUK HOWO dump trucks and mixer trucks operating under extreme payload conditions
• SINOTRUK STEYR series construction and mining vehicles

In all these applications, the right output shaft endures constant rotational stress. When it wears out or develops spline damage, drivers notice vibration, gear noise, or power loss on one side. A prompt replacement with the AZ2210030215 output shaft restores full driveline performance and avoids costly secondary damage to the differential or axle shafts.

Customer Case Study – Output Shaft (Right) AZ2210030215 Bulk Order for East African Distributor

In early 2024, a well-established truck parts distributor based in Dar es Salaam, Tanzania reached out to Mettlead with an urgent requirement. Their clients — local fleet operators running SINOTRUK HOWO dump trucks on mining routes — were experiencing frequent right-side output shaft failures due to overloading and rough terrain conditions. They needed a reliable, cost-effective source for the Output Shaft (Right) AZ2210030215 for the SINOTRUK HW Series Gearbox.

After receiving samples and verifying dimensional accuracy and hardness levels against OEM standards, the distributor placed an initial order of 200 pieces. We delivered within 18 days via sea freight to Dar es Salaam port, packed in custom-branded cartons featuring their company logo. Within three months, reorder volume doubled as word spread among local workshops that the AZ2210030215 output shafts from their supply matched factory-original performance perfectly.

Today, this partner stocks not only the output shaft but also input shafts, synchronizer assemblies, and gearbox bearings from our SINOTRUK HOWO Gearbox Parts catalog. Their feedback is simple: consistent quality, fair pricing, and on-time delivery keep their customers coming back.

Frequently Asked Questions – Output Shaft (Right) AZ2210030215

What is the exact function of the Output Shaft (Right) AZ2210030215 in the HW Series Gearbox?

The right output shaft sits at the rear of the SINOTRUK HW gearbox and transmits rotational torque from the transmission’s mainshaft to the right-side drive axle through a flange or spline coupling. It essentially bridges the gearbox and the axle, ensuring power reaches the wheels on the right side reliably.

How can I tell if the Output Shaft (Right) AZ2210030215 needs replacement?

Common symptoms include abnormal vibration at highway speeds, metallic knocking sounds from the gearbox area, uneven power delivery between left and right wheels, and visible spline wear or pitting when the shaft is inspected during maintenance. If any of these signs appear, replacing the output shaft promptly prevents cascading damage to the differential or companion flange.

Is this Output Shaft (Right) AZ2210030215 an original SINOTRUK part or aftermarket?

Mettlead supplies OEM-equivalent aftermarket parts manufactured to the same dimensional tolerances, material grades, and heat treatment standards as original SINOTRUK components. Each shaft is inspected for hardness, roundness, and spline accuracy before shipping. The result is genuine-spec performance at a significantly lower cost point — ideal for wholesale buyers seeking healthy margins.

What is the typical service life of this output shaft under normal operating conditions?

Under standard loading conditions and with proper gearbox oil maintenance, the Output Shaft (Right) AZ2210030215 typically lasts between 300,000 and 500,000 kilometers. Overloading, inadequate lubrication, or contaminated gear oil can shorten this lifespan considerably, which is why fleet operators in mining and construction environments tend to stock spares proactively.

Can I order a small trial quantity before committing to bulk?

Absolutely. We understand that distributors need to verify product quality before scaling up. We welcome sample orders so you can inspect dimensions, material hardness, and packaging quality firsthand. Once satisfied, we offer flexible MOQ arrangements and volume-based pricing tiers for the AZ2210030215 output shaft.
