Product Introduction

• Structure: An integrated pneumatic-hydraulic booster unit combining a high-strength aluminum alloy hydraulic cylinder and a steel air reservoir. It features precision-machined pistons, high-temperature resistant rubber seals, quick-connect air and hydraulic ports with protective caps, and a dust-proof bellows boot for the push rod

• Performance: The pneumatic-hydraulic design amplifies pedal force to deliver high clutch actuation pressure with minimal driver effort, ideal for heavy-duty applications. The sealed construction prevents contamination of both air and hydraulic systems, maintaining consistent performance even under extreme temperatures and prolonged use

Core Function

1. Force Amplification: Converts low-pressure air and hydraulic pressure into high axial thrust to disengage the clutch, reducing driver pedal effort significantly

2. Dual System Integration: Seamlessly combines pneumatic and hydraulic systems to provide reliable, responsive clutch actuation under heavy loads

3. Contamination Protection: The sealed air reservoir and hydraulic cylinder prevent dirt, water and debris from entering, extending component service life.

Clutch Operation Cylinder MC11 WG9725230052 – Sinotruk Sitrak OEM Replacement

That’s exactly why fleet managers and procurement professionals across Africa, the Middle East, and Southeast Asia trust Mettlead to deliver this genuine-spec replacement part at factory-direct pricing, without compromising on quality or lead time.

As a China-based specialist in Sitrak heavy-duty truck parts, Mettlead supplies thousands of part numbers for SINOTRUK, SHACMAN, FAW, WEICHAI, DONGFENG, and FOTON platforms. Whether you need a single cylinder for urgent maintenance or bulk quantities for your regional distribution warehouse, we make procurement simple, fast, and secure.

Key Features and Benefits of the WG9725230052 Clutch Slave Cylinder

This clutch operation cylinder is not just another aftermarket part — it’s engineered to replicate OEM performance for the MC11 engine platform. Here’s what sets it apart:

• Precise Hydraulic Response: The cylinder’s internal bore and piston assembly deliver consistent hydraulic force, ensuring smooth clutch disengagement every time the driver presses the pedal.
• Durable Seal Construction: High-quality rubber seals resist heat degradation and hydraulic fluid corrosion, which significantly extends the service interval before replacement is needed again.
• Corrosion-Resistant Body: The cylinder housing is treated to withstand harsh operating environments — from dusty African roads to humid tropical climates — without premature rust or pitting.
• Direct Bolt-On Fitment: Manufactured to OEM dimensional specifications, so installation requires no modifications, no adapter brackets, and no guesswork for your workshop technicians.
• Reduced Downtime: Because this part ships ready-to-install with proper fitment, your trucks spend less time in the shop and more time generating revenue on the road.

In addition, Mettlead’s strict quality control process means every WG9725230052 clutch operation cylinder undergoes pressure testing and dimensional verification before it leaves our facility. Consequently, you receive a part that performs reliably from day one.

Technical Specifications – Clutch Operation Cylinder WG9725230052

Accurate specifications matter when you’re sourcing clutch system components for heavy-duty trucks. The table below provides the essential technical data for this part:

Application Scenario – Compatible Vehicles and Use Cases

The WG9725230052 Clutch Operation Cylinder is specifically designed for the following application:

• Compatible Vehicle: Sinotruk Sitrak series trucks equipped with the MC11 engine
• Component Type: Clutch hydraulic slave cylinder (分泵)
• System Role: Receives hydraulic pressure from the master cylinder and converts it into mechanical force to actuate the clutch release bearing, thereby disengaging the clutch disc from the flywheel

This part is commonly replaced during scheduled maintenance intervals, or when the driver reports symptoms such as a soft or sinking clutch pedal, difficulty shifting gears, or visible hydraulic fluid leakage near the transmission bell housing. Moreover, fleet operators managing long-haul Sitrak trucks find that proactive replacement of the clutch slave cylinder prevents costly roadside breakdowns and unscheduled service events.

Frequently Asked Questions – WG9725230052 Clutch Operation Cylinder

What are the symptoms of a failing clutch slave cylinder on a Sitrak MC11 truck?

The most common signs include a soft or spongy clutch pedal, the pedal slowly sinking to the floor without resistance, difficulty engaging or disengaging gears, and visible hydraulic fluid leaking near the transmission housing. If your driver reports any of these issues, the WG9725230052 clutch operation cylinder should be inspected and likely replaced.

Is this WG9725230052 cylinder an OEM part or aftermarket?

This is an OEM-specification aftermarket replacement. It is manufactured to the same dimensional tolerances and performance standards as the original factory-installed part. Every unit is pressure-tested before shipment to ensure it meets or exceeds OEM reliability expectations.

Can hydraulic fluid type affect the lifespan of this clutch cylinder?

Absolutely. Using the incorrect hydraulic fluid — or mixing different fluid types — can cause the internal rubber seals to swell, harden, or deteriorate prematurely. Always use the clutch fluid grade specified in the Sitrak MC11 service manual (typically DOT 4 or equivalent) to maximize cylinder life.

How do I verify this part fits my specific Sitrak truck model?

The primary identifier is the OEM part number WG9725230052. Cross-reference this number against your truck’s parts catalog or the number stamped on your existing clutch slave cylinder. If you’re unsure, send us your VIN or chassis number and our team will confirm compatibility before shipment.

Should I replace the clutch master cylinder at the same time?

While not always mandatory, it’s considered best practice. If the slave cylinder has failed due to age or fluid contamination, the master cylinder’s internal seals have likely experienced similar wear. Replacing both simultaneously prevents a repeat failure shortly after the first repair and saves on labor costs.

What’s the typical service life of this clutch operation cylinder?

Under normal operating conditions and with proper hydraulic fluid maintenance, this cylinder typically lasts between 150,000 and 300,000 km. However, harsh environments, contaminated fluid, or excessive clutch use in stop-and-go traffic can shorten this interval. Regular fluid inspections help you catch degradation early.
