Product Introduction

This precision-machined bushing is engineered to support the shift fork pivot in the transmission’s gear change mechanism, ensuring smooth and precise gear selection.

• Structure & Material: Made from high-strength, wear-resistant steel alloy, it features a precision-machined inner bore for a tight fit on the pivot pin, and an outer diameter that fits securely into the shift fork.

• Performance: The bushing reduces friction between the shift fork and its pivot, enabling smooth, low-effort gear shifts and preventing premature wear of the pivot components.

• Durability: The hardened steel construction resists deformation and wear, providing long service life even under the high loads and frequent shifting of commercial vehicle operation.

• Compatibility: Direct OE replacement, fully matching the dimensional and hardness specifications of the target transmission’s shift mechanism.

Core Function

1. Friction Reduction: Provides a low-friction interface between the shift fork and its pivot pin, enabling smooth and precise gear shifts.

2. Wear Protection: Distributes the load from the shift fork evenly across the pivot, preventing premature wear of both the fork and pin.

3. Alignment Support: Maintains precise alignment of the shift fork, ensuring accurate engagement with the synchronizer sleeves.

Bushing WG2229100001 for SINOTRUK HW Series Gearbox – Factory-Direct Supply from Mettlead

When your SINOTRUK HW series gearbox demands a reliable replacement bushing, precision matters more than anything. The Bushing WG2229100001 is engineered to restore smooth shifting performance and extend gearbox service life in heavy-duty applications. Sourced directly from Mettlead’s manufacturing base in China, this gearbox bushing delivers OEM-level fitment at a competitive factory-direct price — so you can keep your fleet moving without breaking your procurement budget.

As a dedicated supplier of SINOTRUK HOWO truck parts and gearbox components, Mettlead understands the critical role each bushing plays inside a transmission assembly. That is precisely why we maintain strict quality control from raw material selection through final inspection.

Key Features and Benefits of Bushing WG2229100001

This bushing is far more than a simple metal sleeve. It serves as the protective interface between rotating shafts and the gearbox housing, absorbing friction, reducing heat, and preventing premature wear. Here is what sets the WG2229100001 apart:

• Exact OEM Dimensional Accuracy – Manufactured to original SINOTRUK specifications, ensuring drop-in fitment with no machining required.
• Superior Wear Resistance – High-grade alloy composition withstands continuous heavy loads, extending replacement intervals by up to 30% compared to aftermarket alternatives.
• Optimized Surface Finish – Precision-ground inner and outer surfaces reduce rotational friction, contributing to smoother gear engagement.
• Thermal Stability – Maintains structural integrity under sustained gearbox operating temperatures up to 150°C.
• Cost-Effective Maintenance – Factory-direct pricing means lower per-unit cost, which is especially beneficial for fleet operators managing multiple vehicles.

In other words, choosing the right bushing protects the entire gearbox assembly. A worn or incorrectly specified bushing can lead to shaft misalignment, gear tooth damage, and ultimately costly transmission failure.

Technical Specifications

Application Scenarios – Where Does This Bushing Fit?

The Bushing WG2229100001 is specifically designed for the SINOTRUK HW series gearbox, which is widely used across heavy-duty commercial vehicles. If you manage a fleet or distribution network involving any of the following, this part belongs in your inventory:

• SINOTRUK HOWO A7 / T7H / T5G heavy-duty trucks equipped with HW series transmissions
• SINOTRUK SITRAK C7H / C5H models with HW19-series gearboxes
• Mining dump trucks and construction vehicles using SINOTRUK HW transmissions under extreme load conditions
• Logistics and long-haul transport fleets operating HOWO tractor units

Whether your vehicles haul cargo across African highways, navigate Middle Eastern construction sites, or serve Southeast Asian logistics routes, the HW gearbox remains one of the most widely deployed heavy-duty transmissions globally. Consequently, the demand for genuine-quality bushings like WG2229100001 continues to grow year after year.

Customer Case Study – Bushing WG2229100001 in Action

Earlier this year, a fleet maintenance company based in Nigeria reached out to Mettlead with an urgent requirement. They managed over 120 SINOTRUK HOWO trucks operating on long-haul routes, and recurring gearbox noise pointed to worn bushings as the root cause.

After reviewing their specifications, we supplied 300 units of Bushing WG2229100001 for SINOTRUK HW Series Gearbox with white-label packaging under their brand. The shipment arrived within 18 days via sea freight. Once installed, the fleet reported noticeably smoother gear transitions and a measurable reduction in gearbox vibration. Over the following six months, their unscheduled transmission maintenance dropped by approximately 40%.

As a result, they placed a repeat order — this time expanding to include additional gearbox components such as synchronizer rings and shaft seals. This is exactly the kind of long-term partnership Mettlead is built to support.

Frequently Asked Questions (FAQ)

What is the function of Bushing WG2229100001 inside the HW gearbox?

The bushing acts as a bearing surface between rotating shafts and the stationary gearbox housing. It minimizes metal-to-metal contact, reduces frictional heat, and maintains correct shaft alignment during gear changes. Without a properly functioning bushing, the gearbox risks accelerated internal wear and eventual failure.

How do I know if Bushing WG2229100001 fits my vehicle?

This bushing is designed specifically for SINOTRUK HW series gearboxes, including HW15710, HW19710, and HW25716 variants. If your truck uses any of these transmissions — commonly found in HOWO A7, T7H, SITRAK C7H, and similar models — then WG2229100001 is the correct part number.

What are the signs that this gearbox bushing needs replacement?

Common symptoms include unusual noise during gear shifting, increased vibration from the transmission area, difficulty engaging gears, and visible metal particles in the gearbox oil. If you notice any of these, inspecting the bushing should be a priority before secondary damage occurs.

Is this bushing identical to the original SINOTRUK part?

Yes. The Bushing WG2229100001 supplied by Mettlead is manufactured to OEM specifications, matching the original in dimensions, material composition, hardness, and surface treatment. It is a direct replacement that requires no modification during installation.
