Clutch releasing bearing

Clutch releasing bearing Introduction

The Clutch releasing bearing, also referred to as the release bearing, owes its name to the thrust it exerts on the central spring of the clutch. In the majority of modern cars the bearing is located on the clutch shaft. A disturbing sound coming out of the clutch area is a sign that the clutch is malfunctioning.
If this sound disappears after pressing the clutch pedal, it means that the thrust bearing is worn and needs replacing. If you postpone its replacement for too long, you run the risk of damaging it completely, as a result of which you will be unable to disengage the gear box and the powertrain. Consequently, your car will be disabled.

Diagnosing a Clutch Bearing or Bushing Noise

The Clutch Release Bearing
This applies force to the release levers or fingers. In doing so, the release bearing disengages the clutch. The release bearing is designed to operate with minimum friction between the rotating and stationary points of contact. If noise develops from the bell housing area, a few checks can be done.
Start with a road test of the vehicle. Listen for noise with the transmission in gear and the clutch pedal to the floor. Next release the clutch with the transmission in first gear. Noise under this condition indicates a worn release bearing or a worn pilot bearing.
To isolate the two, keep the clutch pedal on the floor and shift the transmission into neutral. If the noise persists, the release bearing is bad. If the noise is gone, the pilot bearing is bad.
A bearing noise that occurs when releasing the clutch pedal to engage the clutch while in neutral, but goes away when the pedal is depressed is caused by a bad transmission input shaft bearing.
Always make sure that all other components are in good condition. Check the clutch linkage for binding or mis-adjustments. Check clutch pedal free play and pedal reserve for proper setting. Check the clutch fork and input shafts for proper alignment.

4 Symptoms of a Bad Clutch releasing bearing

The clutch assembly (consisting of the pressure plate, clutch plate, flywheel, and throw-out bearing), connects the wheels to the engine of the vehicle.
The clutch pedal gives you the ability to temporarily disconnect the wheels from the engine which is needed when shifting gears.
The throw-Clutch releasing bearing, sometimes called a “clutch release bearing”, is a simple yet important component that’s only in use when the clutch pedal is depressed. When you have a bad throw-out bearing, it will affect shifting and can lead to failure of other clutch and transmission components.

How a Throw-Out Bearing Works

In short, a Clutch releasing bearing is the component of the clutch which temporarily disengages a car’s engine from the transmission during gear shifts. When you push the clutch pedal with your foot, the clutch release bearing gets closer to the flywheel. This causes the release fingers of the pressure plate to get pushed in. Once that happens, the fingers of the pressure plate push against the force of its spring. This causes the disconnect between the engine and wheels and allows you to shift into a different gear. When the clutch pedal is released, the throw-out bearing returns to its original position where power from the vehicle’s engine once again is transferred through the transmission into the drive wheels of a car.
