Product Introduction

• Structure: Integral precision forged high strength nickel chromium alloy steel; external helical tooth profilewith internal spline for main shaft mounting. Tooth surface: carburized, quenched, precision ground to HRC 58–62; black oxide anti corrosion finish.

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

Core Function

1. 1st Gear Torque Transmission: Receives torque from the countershaft 1st gear and transfers it to the main shaft, delivering maximum torque for starting, climbing, and heavy hauling.

2. Low Speed Power Output: Implements the lowest gear ratio (≈15.53) in the 12JS200T transmission, providing extreme low speed pulling power.

3. Heavy Load Durability: Withstands frequent low gear operation and extreme torque in construction, mining, and heavy haul conditions.

Key Features and Benefits of the Transmission Gear 12JS200T-1701111

What sets this Fast Gear transmission gear apart from generic alternatives? It comes down to material integrity, precision machining, and real-world durability. Here’s what you gain when you choose this component:

• High-Strength Alloy Steel Construction – Forged from premium-grade alloy steel and heat-treated for optimal hardness and wear resistance, ensuring the gear withstands high-torque loads over hundreds of thousands of kilometers.
• Precision CNC Machining – Every tooth profile is machined to micron-level tolerances, which translates directly into smoother gear engagement, less vibration, and quieter transmission operation.
• OEM-Equivalent Dimensional Accuracy – The 12JS200T-1701111 is manufactured to match original Fast Gear specifications, so it drops into your gearbox assembly without modification or fitment issues.
• Enhanced Surface Treatment – Carburizing and quenching processes create a hard outer layer while maintaining a tough, shock-absorbing core — the ideal combination for heavy-duty transmission components.
• Extended Service Life – Thanks to superior material selection and finishing, this gear consistently outlasts low-cost alternatives, reducing your total cost of ownership and maintenance frequency.
• Factory-Direct Pricing – By sourcing directly from Mettlead, you eliminate middlemen and secure competitive bulk pricing without sacrificing quality control.

In short, this transmission gear doesn’t just fit — it performs. And for procurement managers who need to balance budget constraints with fleet uptime, that performance translates directly into measurable savings.

Customer Case Study – Transmission Gear 12JS200T-1701111 in Action

A fleet maintenance company based in East Africa was experiencing frequent gearbox failures across their 40-vehicle HOWO truck fleet. Their existing supplier delivered inconsistent quality — some transmission gears lasted only 60,000 km before showing excessive wear on the tooth surfaces, leading to hard shifting and eventual gearbox rebuilds.

After switching to Mettlead’s Transmission Gear 12JS200T-1701111 Fast Gear, the results spoke clearly. Over a 12-month evaluation period, zero premature failures were recorded. The gears maintained smooth engagement past the 150,000 km mark, and the fleet’s overall transmission maintenance costs dropped by approximately 35%.

The procurement manager noted three decisive factors: first, the dimensional accuracy meant zero fitment issues during installation; second, the consistent hardness values across batches eliminated the quality lottery they’d experienced before; and third, Mettlead’s factory-direct pricing freed up budget for other critical spares. Today, they source their complete Fast Gear transmission parts inventory through Mettlead on a quarterly replenishment cycle.

Frequently Asked Questions – Transmission Gear 12JS200T-1701111

What gearbox models does the 12JS200T-1701111 transmission gear fit?

This gear is specifically designed for the Fast 12JS200T series transmission. It serves as a direct replacement in gearbox assemblies found in SINOTRUK HOWO, SHACMAN, FAW, and other heavy-duty trucks equipped with Fast 12-speed manual transmissions.

What material is used in this transmission gear, and how does it affect durability?

The gear is forged from 20CrMnTi alloy steel — the same grade specified in OEM production. After carburizing and quenching, the surface reaches HRC 58–62 for wear resistance while the core stays at HRC 30–45 for impact toughness. This combination prevents both surface pitting and tooth fracture under high-torque conditions.

How can I verify that this transmission gear matches OEM dimensions?

We provide full dimensional data upon request, including tooth count, module, pressure angle, and shaft bore diameter. Additionally, our team can cross-reference your existing part number or provide sample gears for your own inspection before committing to bulk orders.

What is the expected service life of this Fast Gear transmission gear?

Under normal operating conditions with proper lubrication and gearbox maintenance, the 12JS200T-1701111 transmission gear typically matches or exceeds OEM service life — generally 200,000+ km depending on load profiles and driving conditions.

Can I order this transmission gear with my own brand packaging?

Absolutely. Mettlead offers full white-label and custom packaging services. You can specify your brand name, logo, label format, and even carton specifications. This is particularly valuable for distributors building their own aftermarket brand identity.

What quality inspections does this gear undergo before shipping?

Each production batch is subjected to dimensional measurement (tooth profile and runout), hardness testing (surface and core), visual surface inspection, and material composition verification. Inspection reports are available upon request for your records.
