What Causes the Burning and Noise of the Release Bearing?

[EmmanuelDella]

Release bearing burning and noise reasons: Burning caused by excessively high working temperatures, commonly seen when drivers habitually use the half-clutch technique, keeping the clutch in a semi-engaged and semi-disengaged state. This causes dry friction heat from the clutch to transfer to the release bearing, leading to the thinning and loss of lubricating grease until the temperature reaches a certain level, resulting in burning damage. The clutch release bearing is installed between the clutch and the transmission. The release bearing housing is loosely fitted on the tubular extension of the transmission's first shaft bearing cover. A return spring ensures that the shoulder of the release bearing always presses against the release fork and retracts to the rearmost position, maintaining a gap of approximately 3 to 4mm with the end of the release lever.
