Product Introduction

• Structure: An integral precision-forged component made from high-strength nickel-chromium alloy steel, with an external helical tooth profile and a precision-machined bore for mounting on the counter shaft. The tooth surface is carburized, quenched, and precision-ground to HRC 58–62 for extreme wear resistance, with a black oxide finish for corrosion protection.

• Performance: The high-hardness helical teeth withstand extreme torque and impact forces, ensuring smooth, quiet meshing with minimal vibration. The integral forging and reinforced hub design prevent deformation under heavy loads, while the precision-machined bore ensures concentricity and precise alignment with the counter shaft.

Core Function

1. Torque Reception: Receives torque from the 5th/6th gear drive gear and transfers it to the counter shaft, enabling power transmission in high-speed, efficient driving scenarios.

2. Gear Ratio Implementation: Works with the 5th/6th gear drive gear to achieve the high gear ratio, balancing speed and fuel efficiency for highway cruising.

3. Heavy-Duty Durability: The high-strength alloy steel and heat treatment withstand frequent shifts and extreme torque in heavy hauling, ensuring long service life.

Whether you are rebuilding a worn 12JS200T transmission or stocking your parts warehouse for ongoing fleet maintenance, this Fast Gear driven gear eliminates guesswork. It drops right in, meshes smoothly with mating components, and keeps your trucks hauling without costly downtime.

Key Features and Benefits of the 12JS200T-1701115 Driven Gear

Choosing the right transmission driven gear is not just about matching a part number. It is about ensuring long service life, quiet operation, and reliable torque transfer under heavy loads. Here is what sets this component apart:

• Exact OEM Specification: Manufactured to match the original Fast Gear 12JS200T-1701115 dimensions, tooth profile, and hardness requirements — so installation is straightforward and performance is predictable.
• Premium Alloy Steel Construction: Forged from high-strength alloy steel, then carburized and heat-treated to achieve a hardened tooth surface with a tough, shock-absorbing core.
• Precision Gear Grinding: Tight tolerances on tooth geometry reduce mesh noise, minimize vibration, and distribute loads evenly across the gear face.
• Extended Service Life: Surface hardness and core toughness work together to resist pitting, spalling, and fatigue — even under sustained high-torque conditions.
• Factory-Direct Pricing: By sourcing straight from Mettlead’s production facility, you cut out middlemen and keep your per-unit cost competitive.
• Strict Quality Control: Every batch undergoes dimensional inspection, hardness testing, and visual examination before shipment — because a failed gear means a stranded truck.

Application Scenarios – Which Vehicles and Gearboxes Does This Gear Fit?

The 12JS200T-1701115 Fast Gear Transmission Driven Gear is designed specifically for the Fast 12JS200T gearbox — one of the most widely deployed 12-speed transmissions in Chinese heavy-duty commercial vehicles. You will commonly find it installed in the following truck platforms:

• SHACMAN (Shaanxi Auto) – F3000, X3000 series tractor heads and dump trucks equipped with Fast 12-speed transmissions.
• SINOTRUK HOWO – Select HOWO A7 and T7H models paired with Fast gearboxes rather than the HW series.
• FAW Jiefang – J6P and J7 heavy haulers utilizing Fast 12JS200T drivetrains.
• FOTON Auman – GTL and EST series heavy-duty trucks with Fast transmission configurations.
• DONGFENG – Tianlong KX and KL flagship models running Fast 12-speed gear systems.

In short, if your vehicle’s transmission carries the Fast 12JS200T designation and the BOM calls for part number 1701115, this driven gear is your match. It is ideal for fleet operators, repair shops, and distributors who service long-haul logistics trucks, mining dump trucks, and construction-site heavy haulers across Africa, Southeast Asia, the Middle East, and Central Asia.

Customer Case Study – Fast Gear Driven Gear 12JS200T-1701115 in Action

A fleet maintenance company based in Nairobi, Kenya, was experiencing repeated transmission noise and premature gear wear on their client’s SHACMAN F3000 dump trucks. The original Transmission Driven Gear 12JS200T-1701115 components had worn beyond specification after extended quarry operations, and locally sourced replacements delivered inconsistent quality.

After discovering Mettlead through an online search for Fast Gear 12JS200T-1701115 driven gear supplier, the procurement manager requested a trial order of 20 units. Within 12 days, the shipment cleared customs in Mombasa. Upon installation, the maintenance team noted precise fitment with no shimming required, smooth meshing characteristics, and noticeably quieter gear engagement compared to their previous supply source.

Six months later, none of the 20 gears showed signs of pitting or abnormal wear. The client has since expanded their orders to include additional Fast gearbox parts — from countershaft gears to synchronizer assemblies — consolidating their transmission parts procurement with Mettlead for consistency and cost savings.

Frequently Asked Questions (FAQ)

What is the function of the driven gear 12JS200T-1701115 inside the Fast gearbox?

The driven gear (also called the output gear or countershaft driven gear) receives torque from the driving gear and transmits it further through the gear train to achieve the selected speed ratio. In the 12JS200T transmission, part number 1701115 occupies a specific position in the main gearbox section, and its tooth profile directly influences shift quality and load-carrying capacity at that ratio.

How can I verify that this transmission driven gear fits my specific truck?

Start by confirming your transmission model — it should read 12JS200T on the gearbox nameplate. Then cross-reference the OEM part number 1701115 against your vehicle’s parts catalog or bill of materials. If you are unsure, send us your truck model, VIN, and gearbox serial number, and our technical team will confirm compatibility.

What material and heat treatment does the 12JS200T-1701115 driven gear use?

This gear is forged from high-strength alloy steel, then undergoes a carburizing process to infuse carbon into the surface layer. After carburizing, the gear is quenched and tempered to achieve a hard wear-resistant surface (HRC 58–63) with a ductile, shock-resistant core (HRC 33–38). This combination prevents tooth breakage under impact while resisting surface pitting over millions of load cycles.

How long does this driven gear typically last in normal operating conditions?

Lifespan depends heavily on operating conditions — load severity, shifting habits, lubrication quality, and maintenance intervals. Under normal long-haul trucking conditions with proper oil changes, you can expect performance comparable to the OEM original, typically exceeding 300,000 km before measurable wear affects shift quality. Severe-duty applications such as mining or heavy construction may reduce this figure.

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

Mettlead supports sample orders so you can inspect quality, verify fitment, and test performance before committing to bulk quantities. Simply contact us with your requirements, and we will arrange a trial shipment.

Does the gear come with any quality documentation?

Yes. Upon request, we can supply material certificates, hardness test reports, and dimensional inspection records. These documents help you maintain traceability and assure your own customers of product quality.
