Product Introduction

• Structure: An integrated hydraulic release bearing with a sealed cylinder, high-precision angular contact ball bearing, and an electronic wear sensor. It features a steel housing with corrosion-resistant plating, a high-temperature resistant rubber bellows seal, and a quick-connect electrical connector for the wear indicator.

• Performance: The hydraulic design provides smooth, linear clutch actuation with minimal pedal effort, even under heavy loads. The integrated wear sensor alerts the driver when the clutch is nearing the end of its service life, preventing unexpected failures. The sealed construction and high-temperature lubrication ensure reliable operation in harsh conditions from -40°C to +180°C.

Core Function

1. Hydraulic Clutch Actuation: Converts hydraulic pressure from the clutch master cylinder into axial thrust to disengage the clutch, enabling smooth gear shifts.

2. Wear Monitoring: The integrated electronic sensor continuously monitors clutch wear and sends a signal to the vehicle dashboard, allowing for proactive maintenance.

3. Smooth & Low-Effort Operation: The hydraulic bearing design eliminates the need for a mechanical release fork, reducing friction and pedal effort for the driver.

Frequently Asked Questions

What does the clutch release bearing 0501.221.020 actually do?

The release bearing — sometimes called the throwout bearing — is the mechanical link between the clutch pedal and the pressure plate. When you press the pedal, this bearing slides along the transmission input shaft sleeve and pushes against the diaphragm spring, separating the pressure plate from the clutch disc. Without it functioning properly, gear changes become rough or impossible.

How do I know when this clutch bearing needs replacement?

There are several telltale signs. You might notice a grinding or whining noise that appears only when the clutch pedal is depressed. Additionally, if the pedal feels stiffer than usual or if the clutch does not fully disengage (causing gear clash), the release bearing is a prime suspect. On MC13-equipped Sitrak trucks, these symptoms often appear between 150,000 and 300,000 km depending on driving conditions and load frequency.

Is this bearing an exact replacement for the original Sinotruk Sitrak part?

Yes. The 0501.221.020 bearing supplied by Mettlead matches the OEM dimensional specifications, material grade, and load ratings. It installs identically to the factory-fitted component — no spacers, adapters, or modifications are necessary.

Can I install this bearing without replacing the entire clutch kit?

Technically, yes — the bearing can be replaced independently. However, since accessing it requires removing the gearbox, most experienced technicians recommend inspecting (and often replacing) the clutch disc and pressure plate at the same time. This avoids repeat labor costs if those components are nearing the end of their service life.

What causes premature failure of a clutch release bearing?

The most common causes include riding the clutch pedal (keeping partial pressure on it while driving), contamination from grease leaks or dust ingress, and misalignment during installation. Using a bearing built to OEM tolerances — like this one — also helps prevent early failure caused by substandard material or machining.

Does Mettlead offer other clutch components for the MC13 Sitrak platform?

Absolutely. We supply a complete range of clutch transmission parts including clutch discs, pressure plates, release forks, and pilot bearings for Sitrak MC13 trucks. You can find them in our clutch parts category.
