Product Introduction

• Structure: Integral precision forged high strength nickel chromium alloy steel; external helical tooth profilewith internal spline for input 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. Power Input: Receives torque from the engine flywheel/clutch and transmits it to the transmission countershaft, initiating the entire power flow.

2. Torque Distribution: Distributes engine torque to the countershaft gears, enabling gear ratio selection and power output.

3. Heavy Load Durability: Withstands extreme input torque (up to 2000N·m) and high speed rotation in heavy hauling, long haul, and off road conditions.

Key Features and Benefits of the Transmission Gear 12JS200T-1701116 Fast Gear

Every component in a gearbox works under extreme torque and heat. That’s why this Fast Gear transmission gear is manufactured to meet or exceed OEM specifications. Here’s what sets it apart:

• Precision-Ground Tooth Profile — Ensures quiet meshing, minimal backlash, and efficient power delivery across all gear ratios.
• High-Grade Alloy Steel Construction — Heat-treated for superior hardness and fatigue resistance, so the gear withstands constant load cycling without premature failure.
• Direct OEM Replacement — Part number 12JS200T-1701116 matches original Fast gearbox dimensions, spline counts, and mounting geometry — no modifications needed.
• Extended Service Life — Carburized and hardened surface resists pitting and scoring, significantly extending the interval between overhauls.
• Strict Quality Control — Each gear undergoes dimensional inspection, hardness testing, and surface finish verification before shipment.
• Cost-Effective Factory Pricing — Sourced directly from our manufacturing partners in China, eliminating middleman markups while maintaining professional-grade quality.

In short, this transmission gear doesn’t just fit — it performs. And because it’s built for the demanding conditions of long-haul and construction applications, you can trust it to hold up where it matters most.

OEM / ODM Capability and White-Label Packaging

We understand that B2B buyers often need more than just parts — you need a supply partner that adapts to your brand and market requirements. Mettlead offers:

• White-Label Packaging — Ship under your own brand with custom boxes, labels, and documentation. Your customers see your name, not ours.
• Custom Packaging Configurations — Single-piece retail-ready packaging or bulk industrial packing — we configure to your downstream needs.
• Cross-Reference Support — If your customer uses a different part numbering system, we’ll match and label accordingly.
• Quality Documentation — Certificates of conformity, material test reports, and dimensional inspection records available on request.

This flexibility makes Mettlead a natural fit for distributors, fleet maintenance companies, and aftermarket parts brands looking to source transmission gears for Fast gearbox systems at competitive prices without sacrificing traceability.

Customer Case Study – Reliable Gearbox Parts for an African Distributor

One of our long-term partners — a truck parts distributor operating across East Africa — approached us after experiencing inconsistent quality from previous suppliers of Fast Gear transmission components. Their workshop customers were reporting premature wear on countershaft gears, particularly the 12JS200T-1701116 transmission gear, within just a few months of installation.

After switching to Mettlead’s supply, they received gears with verified hardness reports and precise dimensional tolerances. Over the following 12 months, warranty returns on Transmission Gear 12JS200T-1701116 Fast Gear dropped by over 70%. The distributor has since expanded their order scope to include synchronizer rings, output shafts, and bearing kits from our broader gearbox parts catalog.

“The gear quality is consistent batch after batch. Our mechanics trust these parts now, and that trust translates directly into repeat orders for us.” — Procurement Manager, East Africa Region

Frequently Asked Questions – Transmission Gear 12JS200T-1701116 Fast Gear

What gearbox model does the 12JS200T-1701116 transmission gear fit?

This gear is designed as a direct replacement for the Fast 12JS200T gearbox. It matches the original OEM gear in tooth profile, spline configuration, and bore dimensions, so installation requires no machining or adaptation.

What material is this Fast Gear transmission gear made from?

The Transmission Gear 12JS200T-1701116 is forged from high-grade alloy steel — typically 20CrMnTi or an equivalent carburizing steel. After forging, it undergoes carburizing, quenching, and tempering to achieve a case hardness of HRC 58–62 with a tough core, giving it excellent wear resistance and impact toughness.

How does Mettlead ensure the quality of each transmission gear?

Every batch goes through a multi-stage inspection process: raw material verification, post-machining dimensional checks (tooth thickness, runout, bore tolerance), hardness testing after heat treatment, and final surface finish measurement. Gears that fall outside specification are rejected before packaging.

Can I order a sample of the 12JS200T-1701116 gear before placing a bulk order?

Absolutely. We encourage new buyers to order samples for fitment and quality verification. Sample lead times are typically shorter than bulk production, and our team can provide full dimensional and material documentation alongside the sample.

What causes premature failure in transmission gears, and how does this gear prevent it?

The most common failure modes in transmission gears are surface pitting (from insufficient case depth), tooth fracture (from low core toughness), and accelerated wear (from poor surface finish). This Fast Gear 12JS200T-1701116 addresses all three through proper carburizing depth, controlled core hardness, and precision grinding to a surface roughness below Ra 0.8 μm.

Do you offer other gears and components for the Fast 12JS200T gearbox?

Yes. Mettlead supplies a comprehensive range of internal components for the 12JS200T and related Fast gearbox models — including drive gears, driven gears, synchronizer assemblies, shift forks, bearings, and seals. Browse our full Fast Gearbox parts collection to find what you need.
