Product Introduction

• Structure: Integral precision-forged high-strength alloy steel (40Cr), featuring a splined inner bore for main shaft connection, a bolted flange for drive shaft mounting, and a black oxide anti-corrosion finish. The splined bore is precision-ground for a tight fit, and the flange surface is machined for flatness to ensure vibration-free operation.

• Performance: The high-strength forging withstands extreme torque (up to 2200N·m) and impact forces, while the precision-machined splines ensure reliable power transfer. The flat flange surface minimizes vibration and prevents drive shaft misalignment.

Core Function

1. Power Transfer: Transmits torque from the transmission main shaft to the drive shaft, delivering power to the drive axle.

2. Connection Interface: Provides a rigid, bolted connection between the transmission and drive shaft, ensuring precise alignment and vibration-free operation.

3. Heavy-Load Durability: Withstands extreme torque and vibration in heavy hauling, long-haul, and off-road conditions.

Customer Case Study – Transmission Output Flange JS220-1701159-7 in Action

Earlier this year, a fleet maintenance company based in Nigeria reached out to Mettlead looking for a reliable source of Transmission Output Flange JS220-1701159-7 Fast Gear replacements. They were managing over 120 SINOTRUK HOWO trucks used for interstate haulage, and recurring flange failures from inconsistent aftermarket suppliers were causing expensive driveline vibrations and unplanned downtime.

After receiving sample units and verifying dimensional accuracy against their OEM specs, they placed an initial order of 200 pieces. The results spoke for themselves — over six months of operation, not a single flange from Mettlead showed premature wear or required early replacement. Their maintenance cycle extended by approximately 30%, and the total cost per unit dropped significantly compared to their previous supplier.

Today, this client sources not only the JS220-1701159-7 output flange but also synchronizer rings, gearbox bearings, and shift forks from our Fast Gearbox catalog. That’s the kind of long-term relationship we aim to build with every buyer.

Frequently Asked Questions – Transmission Output Flange JS220-1701159-7

What exactly does the transmission output flange do in a Fast gearbox?

The output flange serves as the mechanical bridge between the gearbox output shaft and the driveshaft. It transmits rotational torque from the transmission to the rest of the drivetrain. Because it handles constant rotational stress, it must be made from high-strength materials and machined to very tight tolerances — which is exactly what the JS220-1701159-7 delivers.

How do I confirm that the JS220-1701159-7 flange fits my specific vehicle?

The most reliable method is to match the OEM part number. If your vehicle uses a Fast JS220 series transmission and the original flange carries the number JS220-1701159-7, our replacement is a direct fit. If you’re unsure, send us your VIN or gearbox nameplate photo and our technical team will confirm compatibility.

What are common signs that this output flange needs replacement?

Typical symptoms include driveline vibrations at speed, unusual clunking noises during gear engagement, visible wear or scoring on the spline teeth, and oil leakage around the flange seal area. If left unaddressed, a worn flange can damage the driveshaft yoke and output shaft — leading to much costlier repairs.

Is this flange interchangeable with other Fast Gear part numbers?

No. Each output flange is designed with specific spline counts, diameters, and bolt patterns. The JS220-1701159-7 is unique to its gearbox configuration. Installing an incorrect flange can result in improper engagement, accelerated wear, or catastrophic drivetrain failure. Always verify the exact part number before ordering.

What quality assurance does Mettlead apply to this component?

Every Transmission Output Flange JS220-1701159-7 undergoes a multi-stage inspection process including raw material verification, dimensional measurement with CMM (Coordinate Measuring Machine), surface hardness testing, and final visual inspection. We maintain batch traceability, so if any issue arises, we can trace it back to the production run instantly.

Can I order a small quantity first to test quality?

Absolutely. We understand that trust is built over time, especially in cross-border trade. We offer flexible minimum order quantities specifically to allow new customers to evaluate our quality before committing to larger volumes.
