Product Introduction

• Structure: An integrated assembly combining a pneumatic cylinder, hydraulic master cylinder, and pressure control valve. It features a heavy-duty steel housing with a black anti-corrosion finish, a rubber dust boot to protect the push rod, precision-machined aluminum valve components, and quick-connect ports for air and hydraulic lines. The included pushrod ensures a complete, ready-to-install solution.

• Performance: Converts compressed air pressure into hydraulic force to significantly reduce pedal effort, enabling smooth clutch engagement and disengagement even during long hauls. The system maintains a progressive force-stroke relationship for driver control, with manual backup if air pressure fails.

Core Function

1. Pedal Effort Reduction: Provides pneumatic power to the hydraulic clutch system, making pedal operation lighter.

2. Smooth Engagement: Ensures consistent, smooth clutch actuation for improved drivability.

3. Redundancy: Manual control remains available if the pneumatic system fails.

4. Durability: Heavy-duty construction withstands high pressure, vibration, and harsh operating conditions.

Why Choose the WG9114230023 Clutch Booster?

Effortless Clutch Engagement

This hydraulic clutch booster acts as a force multiplier between the driver’s foot and the clutch mechanism. In other words, it takes a light pedal press and converts it into the powerful actuation force required to disengage heavy-duty clutch plates. Consequently, drivers experience less leg strain during long hauls and frequent stop-and-go operations.

Built to Withstand Harsh Conditions

Heavy trucks operate in punishing environments—extreme heat, dust, vibration, and constant pressure cycling. The WG9114230023 clutch booster features a robust cast housing and precision-machined internal components that resist wear and corrosion over thousands of operating cycles. Therefore, you can count on extended service life and fewer warranty claims.

Direct OEM-Spec Replacement

Designed as a direct bolt-on replacement for the original Sinotruk Howo clutch booster, part number WG9114230023, this component matches factory dimensions, port configurations, and performance specifications. This means installation is straightforward—no modifications, no guesswork, no compatibility headaches.

Wholesale Profitability for Distributors

Because we manufacture and source directly from China, our factory-direct pricing gives resellers and wholesale agents healthy margins. Moreover, flexible MOQ options let you test the market or stock up in bulk depending on your business needs.

Technical Specifications – Clutch Booster WG9114230023

Application Scenario – Compatible Vehicle Fitment

The Clutch Booster WG9114230023 is specifically designed to fit the Sinotruk Howo heavy-duty truck series as a clutch hydraulic component. It functions within the pneumatic-hydraulic clutch actuation system, sitting between the clutch master cylinder and the clutch release mechanism.

More specifically, this clutch booster is commonly found in the following applications:

• Sinotruk Howo A7 – tractor heads and cargo trucks equipped with the standard pneumatic-hydraulic clutch system
• Sinotruk Howo 371 / 375 / 380HP models – widely used across African and Middle Eastern markets for long-haul and construction transport
• Sinotruk Howo dump trucks and mixer trucks – where frequent clutch engagement under load makes booster reliability critical

In each of these applications, the WG9114230023 clutch booster ensures that the driver can smoothly disengage the clutch without excessive pedal effort, which is especially important for heavy-loaded vehicles operating in demanding terrain. Additionally, because this is a hydraulic clutch accessory, it works in tandem with the air supply system already built into every Howo truck, making it a seamless integration into the existing drivetrain.

Frequently Asked Questions – Clutch Booster WG9114230023

What does a clutch booster actually do in a Howo truck?

A clutch booster, also called a clutch servo, uses compressed air to amplify the hydraulic force generated when the driver presses the clutch pedal. Without it, disengaging the heavy clutch plates in a Howo truck would require excessive pedal effort, leading to driver fatigue and inconsistent shifting.

How do I know if my WG9114230023 clutch booster needs replacement?

Common symptoms include a hard or stiff clutch pedal, air leaking from the booster unit, slow clutch disengagement, or hydraulic fluid seeping around the booster seals. If the driver notices increased pedal effort or hears hissing air near the clutch mechanism, the booster likely needs inspection or replacement.

Is this clutch booster compatible with other Sinotruk models beyond Howo?

Part number WG9114230023 is specifically cataloged for the Sinotruk Howo series. While some Sinotruk models share similar clutch systems, we always recommend verifying the OEM part number against your truck’s VIN or parts manual to ensure correct fitment. If you need assistance with cross-referencing, feel free to contact us directly.

Can air system issues affect clutch booster performance?

Absolutely. Since the WG9114230023 relies on compressed air (typically 6–8 bar) to function, any drop in air pressure—caused by leaking air lines, a faulty compressor, or a depleted air tank—will reduce booster effectiveness. Always ensure the truck’s pneumatic system is operating within normal pressure ranges before diagnosing a clutch booster fault.

What type of fluid does this clutch booster use?

The hydraulic side of the clutch booster uses standard DOT-rated brake fluid, the same type used in the truck’s clutch master cylinder system. Always use clean, uncontaminated fluid and bleed the system properly after installation to avoid spongy pedal feel or incomplete clutch disengagement.

How should I store clutch boosters in my warehouse?

Store the WG9114230023 in a cool, dry environment away from direct sunlight and moisture. Keep the unit in its packaging until installation to protect the machined ports and rubber seals from dust contamination. Proper storage ensures the seals remain supple and the unit performs correctly when finally installed.
