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.

• 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.

Frequently Asked Questions – Clutch Booster WG9719230025

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

The clutch booster amplifies the hydraulic pressure generated when the driver presses the clutch pedal. Without it, the pedal force required to disengage the clutch on a heavy-duty truck would be extremely high. Essentially, it acts as a force multiplier that makes clutch operation smooth and manageable, even when the truck is fully loaded.

How do I know if my Clutch Booster WG9719230025 needs replacement?

There are several telltale signs. First, if the clutch pedal feels unusually heavy or stiff, the booster’s internal seals may have degraded. Second, if you notice hydraulic fluid leaking from the booster housing, that’s a clear indicator of seal failure. Third, if the clutch doesn’t fully disengage — causing gear grinding — the booster may not be delivering adequate pressure. In all these cases, replacing the booster promptly prevents further damage to the clutch disc and transmission.

Is WG9719230025 interchangeable with other Sinotruk clutch booster part numbers?

Not necessarily. While some Sinotruk models share similar clutch system architectures, the WG9719230025 is specifically dimensioned and calibrated for certain Howo configurations. We strongly recommend matching the exact OEM number to your truck’s VIN or existing part. If you’re unsure, send us your vehicle details and we’ll cross-reference it for you.

What’s the typical lifespan of this clutch booster under normal conditions?

Under standard operating conditions with proper maintenance — including regular clutch fluid changes and system bleeding — this booster can last anywhere from 150,000 to 300,000 kilometers. However, harsh operating environments, contaminated fluid, or excessive heat exposure can shorten its service life. Regular inspection is always recommended.

Can I order a sample before committing to a bulk purchase?

Absolutely. We understand that distributors need to verify quality before scaling orders. Mettlead supports sample orders so you can inspect fitment, finish quality, and packaging before placing a larger commitment. Just reach out to our sales team to arrange it.
