Product Introduction

• Structure: An integrated hydraulic master cylinder constructed from high-strength aluminum alloy with a corrosion-resistant black coating. It features a precision-machined piston, high-temperature resistant rubber seals, a dust-proof bellows boot, and an integrated electronic wear sensor with a quick-connect electrical connector.

• Performance: The aluminum alloy housing provides excellent heat dissipation, maintaining stable hydraulic pressure even under prolonged heavy-duty use. The integrated wear sensor monitors clutch pedal travel and alerts the driver when clutch components are nearing the end of their service life. The sealed design prevents fluid contamination and ensures consistent pedal feel.

Core Function

1. Hydraulic Pressure Generation: Converts the mechanical force from the clutch pedal into hydraulic pressure, which is transmitted to the clutch release bearing to actuate clutch disengagement.

2. Wear Monitoring: The integrated electronic sensor tracks pedal travel to detect clutch wear, providing early warnings to prevent unexpected failures.

3. Stable Hydraulic Performance: The precision-machined piston and high-quality seals ensure consistent pressure delivery, resulting in smooth, predictable clutch operation.

Application Scenario – Where Does the 711W30715-6152 Clutch Master Cylinder Fit?

This clutch master cylinder is specifically designed for the Sinotruk Sitrak series equipped with the MC11 engine. The MC11 powertrain, developed with MAN technology, is widely used across Sitrak’s C7H and C5H heavy-duty truck platforms for long-haul logistics, construction material transport, and bulk cargo operations.

In real-world terms, the 711W30715-6152 is the hydraulic master control component that sits between the clutch pedal and the slave cylinder. When a driver presses the clutch pedal, this cylinder generates the hydraulic force needed to disengage the clutch disc from the flywheel. Without a properly functioning master cylinder, gear shifting becomes difficult, inconsistent, or impossible — leading to transmission damage and roadside breakdowns.

Common replacement scenarios include:

• Clutch pedal feels spongy or drops to the floor
• Visible fluid leak around the master cylinder body or pushrod seal
• Difficulty shifting gears, especially under load
• Clutch fluid level drops repeatedly without visible external leak
• Preventive replacement during scheduled clutch overhaul service

For distributors serving fleets in Africa, Southeast Asia, the Middle East, and Central Asia — where Sitrak trucks dominate heavy transport routes — this part number is a consistent mover. Stocking it means fewer back-orders and faster fulfillment for your customers.

Frequently Asked Questions – Clutch Master Cylinder 711W30715-6152

What are the signs that a clutch master cylinder is failing?

The most common symptoms include a soft or spongy clutch pedal, the pedal sinking to the floor without resistance, difficulty engaging gears, and visible fluid leaks near the cylinder mounting point. In the case of the 711W30715-6152, internal seal wear is typically the root cause — the EPDM seals degrade over time from heat cycles and fluid contamination, allowing hydraulic pressure to bypass the piston rather than actuating the slave cylinder.

Is this clutch master cylinder an exact OEM replacement for Sitrak MC11 trucks?

Yes. The 711W30715-6152 is manufactured to match Sinotruk’s original equipment dimensions, hydraulic output, and mounting configuration. It bolts directly into the same position as the factory-installed unit without requiring any modifications, adapter brackets, or line re-routing.

How long does a clutch master cylinder typically last on a Sitrak MC11 truck?

Under normal operating conditions, a quality clutch master cylinder can last between 150,000 to 300,000 kilometers. However, factors like fluid contamination, extreme temperature cycling, aggressive driving habits, and neglected fluid change intervals can shorten this lifespan significantly. For fleet operators, we recommend inspecting the master cylinder during every clutch service interval.

Can I use DOT 3 fluid instead of DOT 4 in this master cylinder?

While DOT 3 is technically compatible, DOT 4 is recommended for the 711W30715-6152 because it offers a higher boiling point. Heavy-duty trucks like the Sitrak generate more heat in the clutch hydraulic system during prolonged use, and DOT 4 provides better resistance to vapor lock under these conditions. Always flush the system completely if switching fluid types.

What’s the difference between a clutch master cylinder and a clutch slave cylinder?

They work as a team. The master cylinder (711W30715-6152) is mounted near the clutch pedal and creates hydraulic pressure when the driver presses the pedal. The slave cylinder receives that pressure at the transmission end and physically pushes the release bearing to disengage the clutch. If either component fails, the clutch system stops working — so it’s wise to inspect both whenever one is replaced.

Do you offer bulk pricing for orders of 50 units or more?

Absolutely. Mettlead provides tiered wholesale pricing based on order volume. The more units you order, the better your per-unit cost becomes. For a custom quote on the 711W30715-6152 clutch master cylinder, reach out to our sales team with your required quantity and delivery destination.
