Product Introduction

This synchronizer ring is a critical component for smooth, clash-free range shifts, responsible for equalizing the rotational speeds of the range gear seat and range sleeve before engagement.

• Structure & Material: Manufactured from a copper-based friction alloy, with precision-machined internal cone teeth and external gear teeth that match the range gear seat. The green surface coating enhances friction performance and wear resistance.

• Friction Performance: The cone-shaped friction surface generates controlled drag to synchronize rotational speeds, while the gear teeth ensure precise alignment with the range sleeve.

• Durability: The copper alloy construction resists heat and wear under high friction loads, maintaining consistent performance over long service life.

Core Function

1. Speed Synchronization: Uses friction between its cone surface and the range gear seat to equalize rotational speeds, preventing gear clash during range shifts.

2. Precision Alignment: The external gear teeth align with the range sleeve, ensuring smooth engagement with the range gear seat.

3. Wear Resistance: The copper alloy material and green coating withstand high temperatures and friction, ensuring reliable performance under heavy-duty conditions.

Range Gear Syn. Ring WG2210100009 – SINOTRUK HW Series Gearbox Synchronizer Ring

When your SINOTRUK HW series gearbox demands smooth, reliable gear engagement, the Range Gear Syn. Ring WG2210100009 delivers exactly that. This precision-engineered synchronizer ring is purpose-built for the auxiliary box of HW series transmissions, ensuring seamless shifting performance under the toughest operating conditions. As a factory-direct supplier, Mettlead brings you genuine-quality gearbox components at competitive prices — so you can keep your fleet running without breaking your budget.

Why This Synchronizer Ring Matters for Your HW Gearbox

The synchronizer ring sits at the heart of your transmission’s shifting mechanism. It equalizes the rotational speed between gears before engagement, which means less wear, quieter operation, and significantly longer gearbox life. Without a properly functioning syn. ring, you’ll notice grinding during shifts, accelerated component wear, and eventually costly transmission failures.

Here’s what makes the WG2210100009 Range Gear Synchronizer Ring a smart investment for your fleet:

• Precision Friction Surface – Engineered cone geometry provides optimal friction coefficient for fast, smooth synchronization every time.
• High-Grade Material Composition – Manufactured from wear-resistant alloy that withstands high torque loads and extreme heat cycles.
• OEM-Matching Dimensions – Produced to exact SINOTRUK specifications, ensuring perfect fitment without modifications.
• Extended Service Life – Advanced surface treatment resists premature wear, reducing replacement frequency and total cost of ownership.
• Proven Compatibility – Specifically designed for the auxiliary (range) section of HW series gearboxes, covering multiple truck models.

In other words, this synchronizer ring doesn’t just keep your gearbox shifting — it keeps your entire operation moving forward efficiently.

Customer Case Study – WG2210100009 Bulk Order for East African Fleet

Earlier this year, a fleet maintenance company based in Kenya reached out to Mettlead looking for a reliable source of Range Gear Syn. Ring WG2210100009 parts. They managed over 120 SINOTRUK HOWO trucks operating across long-haul routes between Mombasa and Nairobi, and were experiencing frequent range synchronizer failures due to harsh road conditions and heavy loads.

After sampling five pieces of the WG2210100009 synchronizer ring for bench testing and trial installation, their technical team confirmed that our parts matched OEM quality in terms of dimensional accuracy, friction performance, and material hardness. Consequently, they placed a bulk order of 300 units with custom packaging bearing their own brand name.

The result? Their gearbox maintenance intervals extended by approximately 30%, and they reduced unplanned downtime across their fleet. Today, they continue to order the WG2210100009 Range Gear Synchronizer Ring from Mettlead on a quarterly basis — along with other HW series gearbox wearing parts.

This is the kind of partnership we build: reliable product quality, consistent supply, and pricing that protects your margins.

Frequently Asked Questions – Range Gear Syn. Ring WG2210100009

What is the function of the Range Gear Synchronizer Ring WG2210100009 in the HW gearbox?

The WG2210100009 synchronizer ring is responsible for equalizing the rotational speed between the range gears in the auxiliary box of the HW series gearbox. Essentially, it allows smooth high-to-low range shifts by creating controlled friction between the engaging surfaces. Without a functioning syn. ring, drivers will experience grinding, difficulty shifting ranges, and accelerated damage to the range gear teeth.

How can I tell if my WG2210100009 synchronizer ring needs replacement?

Common symptoms include a crunching or grinding noise when shifting between high and low range, difficulty completing range shifts (especially under load), and visible wear on the synchronizer cone surface during inspection. If your truck has over 200,000 km without a gearbox overhaul, it’s wise to inspect the range synchronizer ring for wear marks, scoring, or reduced cone height.

Is this WG2210100009 syn. ring compatible with all HW series gearbox models?

Yes, the WG2210100009 is designed for the auxiliary range section across multiple HW series gearbox variants, including HW19710, HW19712, and related configurations. However, we always recommend confirming your specific gearbox model number to ensure exact compatibility. Feel free to send your gearbox nameplate details to our team for verification.

What material is used for this synchronizer ring, and how does it affect durability?

The WG2210100009 is manufactured from a specialized wear-resistant alloy with a friction-optimized surface treatment. This combination provides excellent heat dissipation during synchronization, resists glazing under high-frequency shifting, and maintains consistent friction characteristics throughout its service life — even in high-temperature operating environments common in tropical climates.
