Product Introduction

• Structure: A robust assembly featuring a cast iron cylinder body, a high-performance piston with sealing rings, an integrated fluid reservoir, and a push rod with a protective dust boot. The reservoir provides a visual fluid level indicator, and the seals are engineered for long life under high pressure.

• Performance: Converts the mechanical force from the clutch pedal into hydraulic pressure, which is then transmitted to the clutch booster cylinder. The design ensures a consistent, progressive feel and precise control over clutch engagement, with minimal pedal effort.

Core Function

1. Force Conversion: Translates mechanical pedal pressure into hydraulic pressure.

2. Pressure Generation: Creates the hydraulic force needed to actuate the clutch system.

3. Precision Control: Ensures smooth and precise clutch engagement and disengagement.

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

Frequently Asked Questions — Clutch Master Cylinder WG9719230013

What are the signs that my Howo clutch master cylinder needs replacement?

The most common symptoms include a spongy or soft clutch pedal, difficulty shifting gears, visible brake fluid leakage near the clutch pedal assembly, and a clutch pedal that sinks to the floor without resistance. Additionally, if you notice air bubbles in the clutch fluid reservoir after bleeding the system, the internal seals of the master cylinder are likely worn out. Replacing the WG9719230013 clutch master cylinder promptly prevents further damage to the clutch slave cylinder and release bearing.

Is this clutch master cylinder an OEM original or aftermarket replacement?

This is an OEM-spec aftermarket replacement manufactured to the same dimensional and performance standards as the original Sinotruk part number WG9719230013. It is a direct bolt-on fit, so there is no need for modifications or adapters. The quality is validated through pressure testing and seal integrity inspection during production.

What type of clutch fluid does the WG9719230013 master cylinder use?

This master cylinder is designed to work with standard DOT 3 or DOT 4 brake fluid, which is the same fluid specified by Sinotruk for the original equipment. It is important to never mix different fluid types, and you should replace the fluid according to the manufacturer’s recommended service interval to maintain optimal hydraulic performance.

Can I use this clutch master cylinder on non-Howo Sinotruk models?

The WG9719230013 is specifically designed for Sinotruk Howo series trucks. However, some Sinotruk SITRAK models may share similar clutch system architecture. We recommend verifying your truck’s original part number before ordering. If you are unsure, contact our parts specialists with your VIN or chassis number, and we will confirm compatibility for you.

How should I install the new clutch master cylinder to ensure proper function?

First, drain the old clutch fluid from the reservoir and disconnect the hydraulic line. Then, unbolt the old master cylinder from the firewall mounting bracket. Install the new WG9719230013 unit, torque the mounting bolts to the manufacturer’s specification, reconnect the hydraulic line, and fill the reservoir with fresh DOT 3 or DOT 4 fluid. Finally, bleed the entire clutch hydraulic system thoroughly until no air bubbles remain in the fluid. A properly bled system should give you a firm, responsive pedal feel.

What is the expected service life of this clutch master cylinder?

Under normal operating conditions and with proper fluid maintenance, the WG9719230013 clutch master cylinder typically delivers reliable service for 150,000 to 250,000 kilometers. However, severe operating conditions — such as frequent stop-start driving, contaminated fluid, or extreme temperatures — can shorten this interval. Regular clutch fluid changes every 40,000 to 50,000 km significantly extend the cylinder’s working life.
