Product Introduction

This half shaft gear is a critical component of the rear axle differential, designed to mesh with the differential’s planetary gears and connect to the axle shaft via internal splines, enabling torque distribution to the wheel.

Structure & Material

• Material: High-strength alloy steel, heat-treated (carburized and quenched) for high surface hardness and core toughness.

• Design: A spur gear with external teeth (to mesh with planetary gears) and internal splines (to attach to the axle shaft). Precision-machined teeth ensure tight meshing tolerance.

Performance

• Torque Transfer: Transmits power from the differential’s planetary gear set to the axle shaft.

• Differential Operation: Allows speed differentiation between left and right wheels during turns.

• Load Handling: Withstands high torque loads in heavy-duty truck rear axle systems.

Durability

• Heat-treated alloy steel resists tooth wear, pitting, and deformation under extreme operating conditions.

• Carburized surface enhances tooth strength, extending service life.

Core Function

1. Torque Distribution: Transfers power from the differential to the rear axle shaft.

2. Wheel Speed Differentiation: Enables independent rotation of left/right rear wheels during turns.

3. Load Bearing: Handles heavy torque loads in the rear axle system.

Rear Axle Differential Half Shaft Gear 81.35106.0036 for Shacman Trucks

When your Shacman truck’s rear axle differential demands a reliable half shaft gear, precision matters more than anything else. The Rear Axle Differential Half Shaft Gear 81.35106.0036 is engineered to work seamlessly within the differential mechanism, transferring power smoothly to each wheel while allowing differential rotation during cornering. Built to OEM specifications, this gear keeps your drivetrain running efficiently — mile after mile, load after load.

At Mettlead, we supply this genuine-spec half shaft gear directly from our factory in China, which means you get competitive pricing without sacrificing quality. Whether you’re managing a fleet or sourcing parts for your workshop, this component delivers the durability and fitment accuracy that Shacman heavy-duty applications require.

Key Features and Benefits of the 81.35106.0036 Half Shaft Gear

This differential half shaft gear isn’t just a replacement part — it’s a performance-critical component that sits at the heart of your rear axle assembly. Here’s what makes it stand out:

• Precise OEM Fitment: Manufactured to match the original 81.35106.0036 specifications, so it drops right into your Shacman rear axle differential without modification.
• Superior Load Capacity: The gear tooth profile is optimized to handle heavy torque loads typical in commercial trucking applications, reducing the risk of premature wear.
• Heat-Treated Alloy Steel: Advanced heat treatment processes ensure the gear surface achieves optimal hardness while maintaining core toughness — a balance that extends service life significantly.
• Smooth Differential Operation: Engineered to mesh precisely with the spider gears and side gears, enabling smooth power distribution even when wheels rotate at different speeds during turns.
• Strict Quality Control: Every gear undergoes dimensional inspection and hardness testing before it leaves our facility, so you can trust what arrives at your door.
• Cost-Effective Factory Direct Pricing: By sourcing directly from Mettlead, you eliminate middlemen and keep your procurement costs under control.

Application Scenario: Where This Half Shaft Gear Works

The 81.35106.0036 Rear Axle Differential Half Shaft Gear is specifically designed for Shacman (SHACMAN/陕汽) heavy-duty trucks. It sits inside the rear axle differential housing, where it cooperates with the differential mechanism to transmit driving force from the crown wheel to the axle shafts.

In practical terms, whenever your truck navigates a curve or encounters uneven road surfaces, the differential allows the left and right wheels to rotate at different speeds. This half shaft gear is the component that makes that possible — it receives torque from the spider gears and delivers it to the axle shaft, ensuring each wheel gets the power it needs without binding or excessive stress on the drivetrain.

Compatible vehicles: Shacman F2000, F3000, X3000, and other models equipped with the rear axle assembly using part number 81.35106.0036. For a complete range of compatible components, explore our Shacman truck parts catalog.

Frequently Asked Questions

What exactly does the half shaft gear do inside the differential?

The half shaft gear (also called a side gear) sits inside the differential case and meshes with the spider gears (pinion gears). Its primary job is to receive rotational force from the differential assembly and transfer it to the axle shaft. Consequently, this allows each drive wheel to rotate independently when the vehicle turns, preventing tire scrubbing and drivetrain stress.

How do I confirm that part number 81.35106.0036 fits my specific Shacman truck?

The most reliable method is to check your vehicle’s original parts catalog or the number stamped on your existing half shaft gear. If you’re unsure, simply send us your truck model, year, and rear axle configuration — our technical team will verify compatibility for you.

What are the signs that a differential half shaft gear needs replacement?

Common symptoms include unusual clunking or knocking noises from the rear axle during acceleration or deceleration, vibration at certain speeds, and uneven tire wear. In more severe cases, you might notice metal particles in the differential oil during routine maintenance, which indicates gear tooth wear or damage.

Is this half shaft gear made from the same material as the original Shacman part?

Yes. Our 81.35106.0036 half shaft gear is manufactured from heat-treated alloy steel with carburizing and quenching surface treatment — the same material composition and processing used in OEM production. This ensures equivalent hardness, wear resistance, and fatigue strength.

Should I replace both half shaft gears at the same time?

While it’s not always mandatory, replacing both side gears simultaneously is generally recommended. Since they work as a pair within the differential, uneven wear between an old gear and a new one can lead to noise, vibration, and accelerated wear on the new component. Additionally, inspecting and replacing the spider gears and thrust washers during the same service interval is good practice.

What quality checks does Mettlead perform on this gear before shipping?

Every half shaft gear undergoes dimensional measurement to verify tooth profile accuracy, bore diameter, and overall geometry. Furthermore, we conduct surface hardness testing to confirm that the heat treatment meets specification. Only parts that pass all inspection criteria are approved for shipment.
