Product Introduction

Structure: A split cylindrical bushing with a steel outer shell and a self-lubricating inner layer (graphite or PTFE embedded in a porous metal matrix). The split design allows for easy installation and ensures a tight fit on the camshaft.Performance: Provides low-friction support for the brake camshaft, ensuring smooth and responsive brake actuation. The self-lubricating inner layer eliminates the need for regular greasing, while the steel outer shell offers excellent wear resistance and load-bearing capacity.Design: Directly interchangeable with original equipment, engineered to fit perfectly with the brake camshaft and housing, maintaining precise alignment and reducing wear.

Core Function

• Friction Reduction: Provides a low-friction interface for smooth brake camshaft rotation, ensuring responsive brake operation.

• Load Bearing: Supports the brake camshaft, distributing loads evenly and reducing wear on the camshaft and housing.

• Self-Lubrication: Eliminates the need for regular maintenance and greasing, reducing downtime and extending service life.

• OE Replacement: Directly interchangeable with the original bushing, preserving the brake system’s performance and safety.

Brake Camshaft Bushings WG9100340017 – Genuine Sinotruk Replacement Parts

When your heavy-duty truck’s braking system demands precision and reliability, every single component matters. The Brake Camshaft Bushings WG9100340017 for Sinotruk vehicles serve as the silent guardians between the camshaft and the brake assembly — reducing friction, minimizing wear, and ensuring every braking action responds smoothly under heavy loads. Sourced directly from our factory, these bushings deliver OEM-grade performance at a competitive price that keeps your fleet running safely and your budget intact.

Why Choose WG9100340017 Brake Camshaft Bushings from Mettlead?

These brake camshaft bushings are engineered to sit snugly around the camshaft body, acting as a protective sleeve that absorbs rotational stress and prevents metal-to-metal contact. Over time, worn bushings lead to sloppy brake response, uneven pad wear, and costly downtime. By choosing quality replacements, you’re investing in consistent braking performance and extended component life.

Key Features and Benefits

• Precision-Machined Dimensions: Manufactured to exact OEM tolerances, these bushings fit perfectly without modification, saving you installation time and labor costs.
• High-Wear Resistance: Crafted from premium alloy materials that withstand continuous rotational friction, heat buildup, and heavy braking loads typical in commercial trucking.
• Reduced Camshaft Wear: The bushing acts as a sacrificial barrier, protecting the more expensive camshaft from scoring and surface damage.
• Smooth Brake Actuation: By maintaining proper clearance and lubrication retention, these bushings ensure the camshaft rotates freely — translating to responsive, predictable braking every time you press the pedal.
• Direct OEM Replacement: Part number WG9100340017 guarantees drop-in compatibility with Sinotruk HOWO rear axle brake assemblies.
• Factory-Direct Pricing: As a China-based supplier, Mettlead eliminates middlemen, passing significant cost savings directly to procurement managers worldwide.

Application Scenarios – Where These Bushings Work

The Brake Camshaft Bushings WG9100340017 are specifically designed for Sinotruk heavy-duty vehicles. They sit within the rear axle brake assembly, cradling the brake camshaft to reduce shaft body wear and guarantee smooth braking action under demanding conditions. Whether your trucks haul construction materials across rugged terrain or transport goods over long highway stretches, these bushings maintain their integrity mile after mile.

Compatible Vehicle Applications

• Sinotruk HOWO 6×4 and 8×4 dump trucks
• Sinotruk HOWO A7 tractor heads
• Sinotruk SITRAK series heavy trucks
• Other Sinotruk models equipped with WG9100340017 brake assemblies

Frequently Asked Questions – Brake Camshaft Bushings WG9100340017

What exactly does a brake camshaft bushing do in a Sinotruk truck?

Think of the brake camshaft bushing as a protective sleeve. It sits between the rotating camshaft and the stationary brake housing, reducing direct metal contact. Without it, the camshaft would grind against the housing, leading to accelerated wear, loose tolerances, and eventually sluggish or uneven braking response.

How do I know when my WG9100340017 brake camshaft bushings need replacement?

Several signs point to worn bushings: excessive play or wobble in the brake camshaft, delayed braking response, unusual metallic noise during braking, or uneven brake shoe wear. If you notice any of these symptoms during routine maintenance, it’s time to inspect and replace the bushings.

Are these brake camshaft bushings compatible with both HOWO and SITRAK models?

Yes. The WG9100340017 part number is used across multiple Sinotruk platforms, including HOWO and SITRAK heavy-duty trucks. However, we always recommend confirming the OEM part number against your vehicle’s service manual or VIN to ensure a perfect match.

What material are these bushings made from, and why does it matter?

These bushings are typically manufactured from copper-based composite alloys or high-strength bearing alloys. These materials offer excellent self-lubricating properties, high fatigue resistance, and thermal stability — all critical for a component that endures constant rotational stress under heavy braking loads.

Can I order a small trial quantity before committing to a bulk purchase?

Absolutely. We understand that procurement managers need to verify quality before scaling up. Mettlead supports trial orders so you can test fitment, material quality, and performance in your own workshop before placing larger volume orders.

Do these bushings require any special tools or procedures for installation?

Installation is straightforward for experienced mechanics. The bushings are designed as press-fit components — you’ll need a hydraulic press or bushing driver tool to seat them properly. No machining or modification of the brake housing is required when using the correct OEM part number.
