Product Introduction

• Structure: A monoblock forging from 20CrMnTi alloy steel, preassembled with 3rd and 4th speed gears, needle roller bearings, and precision-ground support journals. The axle end features a 16-tooth external spline for differential engagement. All gear teeth undergo full carburizing, quenching, and precision grinding, achieving surface hardness HRC 58–62(anti-pitting/wear) and core hardness HRC 33–45 (anti-impact fracture).

• Performance: The fully preassembled design eliminates on-site assembly errors, ensuring perfect gear alignment and bearing preload. The monoblock forging provides high torsional rigidity, while the hardened gears resist wear during medium-to-high speed cruising. The integrated needle bearings reduce friction between gears and the shaft, improving transmission efficiency and reducing heat generation.

Core Function

1. Medium-load power output: Transmits torque from the transmission countershaft to the right drive axle, supporting medium-load cruising scenarios.

2. Multi-speed torque transfer: The integrated 3rd/4th gears deliver torque across medium-to-high speed driving (40–70 km/h).

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

Customer Case Study – Output Shaft Assy AZ2203030206 Bulk Order for East African Fleet

Earlier this year, a fleet maintenance company operating over 120 SINOTRUK HOWO trucks in East Africa approached Mettlead with an urgent requirement. Their trucks — primarily tractor heads fitted with HW19712 gearboxes — were experiencing premature output shaft wear due to demanding terrain conditions. They needed a reliable supply of Output Shaft Assy (Right) AZ2203030206 parts at a competitive price point.

After receiving their inquiry, our technical team confirmed compatibility with their specific HW series gearbox models within 24 hours. We then shipped an initial order of 50 units with neutral packaging, delivered via sea freight in just 18 days. The client reported that the replacement output shafts performed identically to the original factory parts, and most importantly, their gearbox failure rate dropped by over 40% in the following quarter.

As a result of this successful partnership, the client now places quarterly bulk orders for gearbox components — including synchronizer assemblies, countershafts, and bearing kits — all sourced through Mettlead’s SINOTRUK parts supply chain.

Frequently Asked Questions – Output Shaft Assy (Right) AZ2203030206

What gearbox models does the Output Shaft Assy (Right) AZ2203030206 fit?

This output shaft assembly is designed specifically for the SINOTRUK HW series gearbox, including popular models such as HW19710, HW19712, and HW15710. It mounts on the right-side output position and is used in HOWO, SITRAK, and other SINOTRUK heavy-duty trucks equipped with HW transmissions.

How can I verify that AZ2203030206 is the correct part number for my truck?

The most reliable method is to check your gearbox nameplate or refer to the original parts catalog for your specific truck model. Additionally, you can provide us with your VIN number or gearbox serial number, and our team will cross-reference compatibility for you at no cost.

What causes the right-side output shaft assembly to fail?

Common causes include insufficient lubrication, bearing wear that allows shaft runout, overloading beyond the gearbox’s rated torque capacity, and normal spline wear over extended mileage. Harsh operating conditions — such as frequent off-road driving or continuous heavy hauling — can accelerate fatigue on the shaft surfaces.

Is this output shaft assembly an OEM original part or aftermarket replacement?

Mettlead supplies OEM-equivalent aftermarket parts manufactured to the same dimensional and material specifications as the original AZ2203030206. Every unit passes strict quality control inspections including hardness testing and dimensional verification, so performance matches OEM standards.

What is the typical service life of the Output Shaft Assy (Right) AZ2203030206?

Under normal operating conditions with proper lubrication and within rated load limits, this output shaft assembly typically lasts 300,000 to 500,000 kilometers. However, actual service life depends heavily on driving conditions, maintenance intervals, and load factors.

Can I order the output shaft assembly together with related gearbox components?

Absolutely. Many of our clients order complete gearbox overhaul kits that include the output shaft, bearings, seals, synchronizer rings, and gears as a package. This approach simplifies procurement and ensures all components are compatible. Visit our SINOTRUK HOWO Gearbox Parts page for the full component list.
