Product Introduction

• Structure: Integral precision forged high strength alloy steel; 46 tooth helical gear(high range) with internal spline hub. Tooth surface: carburized, quenched, precision ground to HRC 58–62; reinforced hub for high torque; black oxide anti corrosion finish.

• Performance: High hardness resists extreme torque/impact; helical teeth ensure quiet, smooth meshing; integral forging prevents deformation under heavy load; precision grinding minimizes backlash and maximizes power transfer efficiency.

Core Function

1. Auxiliary Box Power Input: Transmits torque from the main transmission output to the auxiliary gearbox, enabling high/low range switching.

2. High Range Torque Transfer: Drives the high range gear train to deliver overdrive ratios for highway cruising.

3. Heavy Load Durability: Withstands frequent range shifts and extreme torque in heavy hauling, long haul, and off road conditions.

The Transmission Auxiliary Gearbox Drive Gear 12JS160T-1707030 from Mettlead delivers factory-grade performance designed specifically for Fast Gear transmission systems. Built to handle extreme torque loads and continuous shifting cycles, this drive gear keeps your fleet moving without costly downtime. Whether you’re managing a transport company or sourcing parts for your workshop, this component offers the durability and dimensional accuracy that professional applications require.

Key Features and Benefits of the 12JS160T-1707030 Drive Gear

Every detail of this Fast Gear auxiliary gearbox drive gear is engineered to meet or exceed OEM specifications. Here’s what sets it apart from generic alternatives:

• OEM-Equivalent Precision: Manufactured to match the exact dimensional tolerances of the original 12JS160T-1707030 part number, ensuring seamless installation without modifications.
• Premium Material Composition: Forged from high-strength alloy steel with advanced heat treatment, this gear resists wear, pitting, and fatigue even under sustained heavy loads.
• Optimized Tooth Profile: The gear tooth geometry is precision-ground to promote smooth meshing, reduce noise, and distribute torque evenly across the contact surface.
• Extended Service Life: Surface hardening treatment creates a wear-resistant outer layer while maintaining a tough, shock-absorbing core — the ideal combination for long-haul applications.
• Strict Quality Control: Each gear undergoes rigorous inspection including hardness testing, dimensional verification, and surface finish analysis before shipping.
• Cost-Effective Factory Pricing: As a direct manufacturer based in China, Mettlead eliminates middlemen and passes those savings on to you.

In other words, you get a transmission component that performs like the original — at a fraction of the dealer price. That’s the kind of value that keeps procurement managers coming back.

Technical Specifications

Below you’ll find the detailed parameters for the Transmission Auxiliary Gearbox Drive Gear 12JS160T-1707030. These specifications help you confirm compatibility before placing your order:

Application Scenarios: Where Does This Gear Fit?

The 12JS160T-1707030 auxiliary gearbox drive gear is specifically designed for the Fast Gear 12JS160T transmission — one of the most widely used heavy-duty gearboxes across Chinese truck platforms. Here’s where you’ll typically find this part at work:

• Compatible Transmission: Fast Gear (法士特) 12JS160T series manual transmission
• Applicable Vehicles: SHACMAN F3000/X3000, SINOTRUK HOWO A7/T7H, FAW J6P, FOTON Auman GTL, and other heavy-duty trucks equipped with Fast Gear transmissions
• Typical Use Cases: Long-haul logistics fleets, mining transport vehicles, construction site dump trucks, and heavy cargo carriers operating under demanding conditions
• Maintenance Context: Replacement during scheduled overhauls, after bearing failure causes secondary gear damage, or when worn gear teeth create shifting difficulty and abnormal noise in the auxiliary section

If your drivers report rough shifting between high and low range, or you notice metal particles in the transmission oil during routine checks, the auxiliary gearbox drive gear is one of the first components your technicians should inspect.

Customer Case Study: Fleet Overhaul in East Africa

Earlier this year, a transport logistics company based in Tanzania reached out to Mettlead with an urgent challenge. Their fleet of 40+ SHACMAN F3000 trucks — all equipped with Fast Gear 12JS160T transmissions — was experiencing a wave of auxiliary gearbox failures after 300,000+ kilometers of service. The transmission auxiliary gearbox drive gear 12JS160T-1707030 had worn beyond specification on over a dozen units, causing rough range shifting and increased fuel consumption.

Their procurement manager needed a reliable supply of Fast Gear auxiliary gearbox drive gears at a competitive price — and they needed them fast. After verifying our part samples against OEM drawings, they placed an initial order of 60 pieces. All gears passed their incoming QC inspection, and the first batch of trucks returned to full operation within two weeks of delivery.

Three months later, not a single replaced gear showed premature wear. The client has since expanded their regular orders to include synchronizer assemblies and countershaft gears from our Fast Gearbox product line. That’s the kind of partnership we aim to build — one gear at a time.

Frequently Asked Questions

What vehicles is the 12JS160T-1707030 drive gear compatible with?

This auxiliary gearbox drive gear fits any heavy-duty truck equipped with the Fast Gear 12JS160T series transmission. Common vehicle models include SHACMAN F3000/X3000, SINOTRUK HOWO A7, FAW J6P, and FOTON Auman GTL. However, always confirm the part number against your existing gear or transmission assembly plate before ordering.

What is the function of the auxiliary gearbox drive gear in a Fast Gear transmission?

The auxiliary gearbox drive gear (副箱主动齿轮) transfers power from the main gearbox section into the auxiliary range section. It’s the primary driving component that enables high/low range shifting, effectively doubling the number of available gear ratios. When this gear wears out, you’ll notice difficulty engaging range shifts and possible grinding or whining noises from the rear of the transmission.

How can I tell if my 12JS160T-1707030 drive gear needs replacement?

Several symptoms point to a worn auxiliary gearbox drive gear: hard or incomplete range shifts between high and low, unusual metallic noise from the transmission tail section, metal debris found in the gearbox oil during drain intervals, and visible tooth surface pitting or chipping during overhaul inspections. If two or more of these symptoms appear together, replacement is strongly recommended.

Is this gear made from the same material as the original Fast Gear part?

Yes. We use the same grade of carburized alloy steel specified for the OEM component. Our heat treatment process — carburizing, quenching, and tempering — achieves surface hardness of HRC 58–62 with core hardness of HRC 30–42, matching the original design intent for wear resistance and impact toughness.

Can I order a single piece for testing, or is there a minimum order quantity?

We welcome sample orders so you can verify fit, finish, and quality before committing to volume. For specific MOQ details and sample pricing on the 12JS160T-1707030 transmission auxiliary gearbox drive gear, simply reach out to our team and we’ll provide a tailored quote within 24 hours.

How is the gear packaged for international shipping?

Each gear is individually wrapped in anti-rust oil film, cushioned with foam padding, and boxed in a sturdy carton. For bulk orders, we palletize and reinforce packaging to withstand ocean freight handling. Custom branded packaging is available upon request at no significant additional cost.
