SACHS CLUTCH RELEASER
Manufacturing part number 3151 000 034

A clutch release bearing, also known as a throw-out bearing, is a crucial component in a car's manual transmission system. Its primary function is to engage and disengage the clutch by applying pressure to the clutch plate, resulting in smooth shifting of gears. The bearing is situated between the clutch fork and the pressure plate, allowing it to rotate freely.

When the clutch pedal is depressed, it pushes the clutch fork forward, which in turn presses against the release bearing. The bearing then applies pressure on the diaphragm spring of the pressure plate, causing it to release the clutch disk from the flywheel. This disengages the clutch, allowing the driver to change gears without grinding or damaging the transmission system. Conversely, when the clutch pedal is released, the bearing retracts the pressure plate, engaging the clutch and transmitting power from the engine to the transmission.
