Product Introduction

• Structure: An integral precision-forged component made from high-strength nickel-chromium alloy steel, with an external helical tooth profile and an internal spline bore. The tooth surface is carburized, quenched, and precision-ground to a hardness of HRC 58–62 for extreme wear resistance, and finished with a corrosion-resistant black oxide coating.

• Performance: The high-hardness tooth surface withstands extreme torque and impact forces, while the helical tooth design ensures smooth, quiet power transmission with reduced vibration. The internal spline provides a rigid connection to the main shaft, preventing slippage and ensuring consistent torque transmission even under heavy loads.

Core Function

1. Gear Speed Synchronization: Works with the synchronizer ring to equalize the rotational speed of the target gear and main shaft, eliminating gear clash during shifting.

2. Smooth Gear Engagement: The helical tooth profile ensures gradual meshing with the sliding sleeve, reducing noise and vibration for a smoother driving experience.

3. Torque Transmission: Once synchronized, the gear locks onto the sliding sleeve, transferring torque from the main shaft to the output.

Customer Case Study – Synchronizer Gear 17568 in Action

Last year, a fleet management company based in Nigeria reached out to Mettlead with an urgent challenge. They operated over 200 SHACMAN X3000 trucks, and frequent gear-shifting problems were causing costly downtime across their logistics network. After diagnosing the issue, their workshop team identified worn synchronizer gear 17568 components in multiple Fast gearbox units as the root cause.

Within 48 hours of their initial inquiry, our sales team provided a detailed quotation for 500 pieces of the Synchronizer Gear 17568 for Fast Gearbox, along with technical documentation confirming compatibility. The order shipped within 10 days, and upon installation, the client reported immediate improvements: smoother shifting, reduced noise, and zero gearbox-related breakdowns over the following six months.

Today, that same company reorders quarterly and has expanded their purchasing to include synchronizer rings, output shafts, and other Fast Gearbox replacement parts from our catalog. Their procurement manager told us: “Mettlead made our gearbox maintenance predictable and affordable. The synchronizer gear 17568 quality matches OE, and the pricing lets us stock strategically.”

Frequently Asked Questions – Synchronizer Gear 17568 Fast Gearbox

What is the function of the Synchronizer Gear 17568 in a Fast Gearbox?

The synchronizer gear 17568 acts as the sliding sleeve (gear hub) within the synchronizer assembly. Its primary job is to connect and lock the selected gear to the transmission shaft during shifting. Without a properly functioning synchronizer gear, drivers would experience grinding, difficult shifts, and eventually transmission failure.

How do I know if my Synchronizer Gear 17568 needs replacement?

Common signs of a worn synchronizer gear include grinding noises during gear changes, difficulty engaging specific gears, gear pop-out under load, and excessive play in the shift mechanism. If your drivers report any of these symptoms, inspecting the synchronizer assembly — including the 17568 gear sleeve — should be a priority.

Is this Synchronizer Gear 17568 compatible with all Fast Gearbox models?

The 17568 synchronizer gear is designed for specific Fast gearbox models. While it fits many 9-speed, 10-speed, and 12-speed Fast transmission variants used in SHACMAN, HOWO, FAW, and DONGFENG trucks, we always recommend confirming your gearbox model number with our team before ordering. Simply contact us with your VIN or gearbox nameplate information for verification.

What material is the Synchronizer Gear 17568 made from?

Our synchronizer gear 17568 is manufactured from high-strength alloy steel, then undergoes carburizing and quenching heat treatment. This process creates a hard, wear-resistant outer surface (HRC 58–62) while maintaining a tough, shock-absorbing core — ideal for the repeated engagement cycles a synchronizer endures.

Can I order a sample before committing to a bulk purchase?

Absolutely. We encourage procurement managers to request samples for quality evaluation and fitment testing. Sample orders for the synchronizer gear 17568 ship quickly, and our team provides full technical support throughout the evaluation process.

How does Mettlead ensure quality control for the Synchronizer Gear 17568?

Each batch undergoes a multi-stage inspection protocol: raw material certification, in-process dimensional checks during CNC machining, post-heat-treatment hardness testing, and final visual and functional inspection. We maintain full traceability records, so you can verify the quality history of every shipment.
