Product Introduction

This precision-machined bushing is designed to support the transmission’s shift shaft or control rod, enabling low-friction, precise movement for reliable gear shifting.

• Structure & Material: Made from high-strength, wear-resistant alloy steel with precision-ground inner/outer diameters; surface undergoes carburizing and quenching for high hardness and wear resistance.

• Performance: Provides a tight, low-friction bearing surface for the shift shaft/rod, eliminating play and ensuring crisp, accurate gear engagement; reduces shift effort and prevents binding.

• Durability: Resists abrasion, deformation, and fatigue under frequent shifting and heavy-duty operation; maintains dimensional stability for long service life.

• Compatibility: Direct OE replacement, fully matching the bore size, length, and fit specifications of the HW19710 transmission’s shift control housing.

Core Function

1. Shaft Support & Guidance: Supports the shift shaft/control rod within the transmission housing, maintaining proper alignment for precise gear selection.

2. Friction Reduction: Minimizes sliding friction between the shaft and housing, ensuring smooth, effortless shifting.

3. Wear Isolation: Acts as a sacrificial wear component, protecting the more expensive shift shaft and housing from premature wear.

The Bushing WG2229020005 is specifically designed for the SINOTRUK HW series gearbox, one of the most widely used heavy-duty transmissions across global markets. More specifically, this bushing serves as a critical wear component inside the gearbox housing, providing a low-friction bearing surface that supports rotating shafts and maintains precise gear alignment.

Compatible vehicles and applications include:

• SINOTRUK HOWO A7, HOWO T7H, and HOWO T5G heavy-duty trucks
• SINOTRUK SITRAK C7H and C5H series tractors and cargo trucks
• Vehicles equipped with HW19710, HW19712, HW15710, and HW13710 transmissions
• Mining trucks, long-haul tractors, and construction vehicles using HW series gearboxes

In everyday terms, this bushing sits at the heart of your transmission assembly. When it wears down, you’ll notice increased gear noise, difficulty shifting, and eventually — if left unattended — more costly internal damage. Replacing it on schedule is one of the most cost-effective maintenance steps you can take to protect your HW gearbox investment.

Customer Case Study: Bushing WG2229020005 in Action

Earlier this year, a fleet maintenance company based in East Africa reached out to Mettlead with an urgent requirement. They were managing over 120 SINOTRUK HOWO trucks used in mining logistics, and recurring gearbox noise had become a growing concern across their fleet. After diagnosing the issue, their mechanics identified worn bushings inside the HW series gearboxes as the root cause.

The company’s procurement manager needed to source Bushing WG2229020005 in bulk — quickly and affordably. Local suppliers quoted high prices with lead times of 6–8 weeks. After finding Mettlead online, they submitted an inquiry through our website.

Here’s what happened next:

1. Our team confirmed the part number WG2229020005 and cross-referenced it with the customer’s specific HW gearbox models within 24 hours.
2. We provided a factory-direct quotation that was 35% lower than their local supplier’s price.
3. Production and quality inspection were completed within 10 working days.
4. The shipment arrived via air freight in just 7 days after dispatch.

The result? The customer replaced worn bushings across 45 trucks in a single maintenance cycle, eliminating gearbox noise and preventing further internal wear. They’ve since placed three repeat orders for SINOTRUK HW gearbox bushing WG2229020005 and expanded their parts list to include other transmission components from our catalog.

“The quality matched OEM standards, and the price gave us room to stay competitive in our own market. Mettlead made the whole process surprisingly easy.” — Procurement Manager, East Africa

Frequently Asked Questions – Bushing WG2229020005

What is the function of Bushing WG2229020005 inside the HW gearbox?

This bushing acts as a bearing surface between rotating shafts and the gearbox housing. It reduces metal-to-metal friction, supports shaft alignment, and absorbs operational vibration. Without a properly functioning bushing, gears can misalign, leading to accelerated wear, noise, and eventually transmission failure.

How do I know when the Bushing WG2229020005 needs replacement?

Common symptoms of a worn gearbox bushing include unusual humming or whining noises from the transmission, difficulty engaging gears, excessive play in the gear lever, and visible metal debris in the gearbox oil. If you notice any of these signs during routine maintenance, inspecting and replacing the bushing is a smart first step.

Is this bushing compatible with all SINOTRUK HW gearbox variants?

The WG2229020005 bushing is designed for the SINOTRUK HW series gearbox family, including models such as HW19710, HW19712, HW15710, and HW13710. However, since gearbox configurations can vary by production year and truck model, we recommend confirming your exact gearbox assembly number with our team before ordering.

What material is used in manufacturing this gearbox bushing?

This bushing is typically manufactured from a high-strength copper-based alloy or composite bearing material. These materials are chosen specifically for their excellent friction properties, thermal stability, and load-bearing capacity under the demanding conditions found inside heavy-duty transmissions.

Can I order a sample of Bushing WG2229020005 before committing to a bulk purchase?

Absolutely. We encourage new customers to request samples for dimensional verification and quality assessment. Sample orders help you validate fit and finish before scaling up. Simply reach out to our team, and we’ll arrange a sample shipment promptly.

How should I store this bushing before installation?

Store the bushing in a clean, dry environment away from moisture, dust, and direct sunlight. Keep it in its original packaging until installation to prevent surface contamination or corrosion. Applying a thin film of clean transmission oil before fitting helps ensure smooth installation and immediate lubrication on startup.
