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 alloy steel with precision-ground inner and outer diameters. The surface is carburized and quenched to achieve high hardness and exceptional wear resistance.

• Performance: Provides a low-friction interface between the shift fork and its pivot pin, enabling smooth, low-effort gear shifts and preventing premature wear of both components. Eliminates play to ensure crisp, accurate engagement with synchronizer sleeves.

• Durability: The hardened steel construction resists abrasion, deformation, and fatigue under frequent shifting and heavy loads, maintaining dimensional stability for long service life.

• Compatibility: Direct OE replacement, fully matching the dimensional and hardness specifications of the HW19710 transmission’s shift mechanism.

Core Function

1. Friction Reduction: Minimizes sliding friction between the shift fork and its pivot, ensuring smooth, effortless gear changes.

2. Wear Protection: Distributes load evenly across the pivot, acting as a sacrificial component to protect the more expensive shift fork and pivot pin.

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

Customer Case Study: Bushing WG2229100002 in Action

Earlier this year, a fleet maintenance company based in East Africa reached out to us with an urgent requirement. They were managing over 120 SINOTRUK HOWO tipper trucks used in mining operations, and their gearboxes were experiencing premature wear due to substandard replacement bushings sourced from local markets.

After switching to the genuine Bushing WG2229100002 supplied by Mettlead, the results spoke for themselves. Gearbox service intervals extended by approximately 40%, gear shifting became noticeably smoother, and the fleet’s unplanned downtime dropped significantly over the following six months.

The procurement manager noted that the SINOTRUK HW series gearbox bushing WG2229100002 fit perfectly without any rework, which saved their technicians valuable workshop time during each gearbox overhaul. Today, they continue to order this bushing in bulk alongside other HW gearbox wear components through Mettlead.

This is a story we see repeated across markets in Africa, Southeast Asia, the Middle East, and Central Asia — wherever SINOTRUK trucks are working hard, our parts keep them running.

Frequently Asked Questions (FAQ)

What is the function of Bushing WG2229100002 inside the HW gearbox?

The Bushing WG2229100002 serves as a bearing surface that supports rotating shafts within the SINOTRUK HW series gearbox. It reduces metal-to-metal contact, minimizes friction, and helps maintain proper shaft alignment during gear engagement. Without a properly functioning bushing, gearbox components wear out much faster.

How do I know when this gearbox bushing needs replacement?

Common signs include increased gear noise, difficulty shifting, unusual vibration during acceleration, or visible play in the gearbox shaft. During any major transmission overhaul, it is strongly recommended to inspect and replace the bushing as a preventive measure, even if it has not completely failed yet.

Is Bushing WG2229100002 an OEM-spec part?

Yes. This bushing is manufactured to match the original equipment dimensions, material grade, and surface finish specified for the SINOTRUK HW series gearbox. It functions as a direct replacement — no machining or modification is required for installation.

Can I order Bushing WG2229100002 in bulk with custom packaging?

Absolutely. Mettlead supports bulk orders with neutral, white-label, or fully customized packaging. Simply provide your packaging design and order quantity, and we will handle the production and labeling to your specifications.

What is the typical lead time for this bushing?

For standard orders, most items ship within 3–7 business days after payment confirmation. Large bulk orders may require 10–15 days depending on quantity. We always communicate realistic timelines upfront so your supply chain stays on track.

Does this bushing fit other gearbox series besides HW?

No. The WG2229100002 is specifically designed for the HW series gearbox. Using it in a different transmission model could result in improper fit and potential damage. If you need bushings for other gearbox types, please contact our team and we will help you identify the correct part number.
