Product Introduction

• Structure: Integral precision forged high strength nickel chromium alloy steel (20CrMnTi); 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 and high speed rotation in heavy hauling, long haul, and off road conditions.

Key Features and Benefits of the JS150-1701030 Transmission Gear

Choosing the right transmission gear is not just about fitment — it is about durability, noise reduction, and long-term value. Here is what sets this Fast Gear component apart:

• Precision-Machined Tooth Profile – Each tooth is cut and ground to tight tolerances, ensuring smooth meshing, minimal backlash, and quiet operation even under high torque conditions.
• High-Grade Alloy Steel Construction – Forged from carburized alloy steel with surface hardening treatment, this gear resists wear, pitting, and fatigue over hundreds of thousands of kilometers.
• Direct OEM Replacement – Part number JS150-1701030 matches original Fast Gearbox specifications, which means no modifications are needed during installation.
• Strict Quality Control – Every batch undergoes hardness testing, dimensional inspection, and surface finish verification before leaving our facility.
• Factory-Direct Pricing – Because we source and ship directly from our warehouse in China, you eliminate middlemen and reduce your per-unit procurement cost significantly.
• Custom Packaging Available – We offer white-label and custom packaging options for distributors who need branded or neutral boxes for their local markets.

In other words, this transmission gear gives you OEM-level performance without the OEM-level price tag. That is a real competitive advantage for bulk buyers and fleet managers alike.

Application Scenarios – Where Does the JS150-1701030 Gear Fit?

This Transmission Gear JS150-1701030 is purpose-built for Fast Gearbox assemblies commonly found in Chinese-manufactured heavy-duty trucks. Specifically, it fits the following applications:

• SHACMAN Heavy Trucks – Models equipped with JS150 series Fast transmissions for long-haul cargo and construction use.
• SINOTRUK HOWO Trucks – Certain HOWO configurations that use Fast Gearbox units rather than the standard HW series.
• FAW Heavy-Duty Vehicles – FAW trucks running JS150 Fast transmissions in mining, logistics, and municipal applications.
• DONGFENG Commercial Trucks – Select Dongfeng models paired with Fast Gearbox drivetrains for regional and intercity transport.
• FOTON Trucks – Foton Auman and other heavy-duty series using Fast transmission configurations.

In short, if the truck runs a JS150 series Fast transmission, this gear is your direct-fit replacement. It is commonly needed during gearbox overhauls, scheduled maintenance programs, or after diagnosing gear noise, hard shifting, or tooth damage.

Customer Case Study – JS150-1701030 Transmission Gear Bulk Order for East African Distributor

Earlier this year, a truck parts distributor based in Tanzania reached out to us with a recurring problem. Their customers — mostly fleet operators running SHACMAN and SINOTRUK trucks — were experiencing premature gear failure in their Fast transmissions. The locally sourced Transmission Gear JS150-1701030 replacements they had been buying showed inconsistent hardness and poor tooth finish, leading to repeat failures within 30,000 km.

After reviewing our product specifications and requesting a sample batch, the distributor placed an initial order of 200 units of the JS150-1701030 Fast Gear with custom-branded packaging. We shipped within 12 days via sea freight to Dar es Salaam.

The result? Zero warranty claims after six months in the field. The distributor has since doubled their quarterly order volume and expanded their range to include additional Fast Gearbox transmission components from our catalog. Their feedback confirmed what we already knew: factory-direct quality at competitive pricing builds trust and repeat business.

This is exactly the kind of partnership we build at Mettlead — reliable parts, transparent communication, and long-term value for your bottom line.

Frequently Asked Questions – Transmission Gear JS150-1701030

What trucks is the JS150-1701030 transmission gear compatible with?

What material is used in this transmission gear, and how is it hardened?

The gear is forged from 20CrMnTi carburized alloy steel — the same grade used in original equipment manufacturing. It undergoes carburizing, quenching, and tempering to achieve a surface hardness of HRC 58–62, while the core maintains HRC 30–45 for toughness and shock resistance.

How does this aftermarket gear compare to the original Fast Gear OEM part?

We manufacture to OEM-equivalent specifications, including tooth profile geometry, material composition, and heat treatment processes. The dimensional tolerances and surface finish match original parts. The primary difference is pricing — our factory-direct model eliminates distribution markups without compromising quality.

What causes a JS150-1701030 transmission gear to fail prematurely?

Common causes include contaminated transmission oil, misaligned synchronizers, overloading beyond rated capacity, and using substandard replacement gears with incorrect hardness. To extend gear life, always use clean, properly graded lubricant and inspect mating components during overhaul.

Can I order this gear with my own brand packaging?

Absolutely. We offer white-label and fully customized packaging for the JS150-1701030 transmission gear. Simply provide your artwork or branding guidelines, and we will handle the rest. This service is available for orders meeting our minimum packaging quantity.
