SUBJECT:
Clutch Release Bearing with Plastic Sliding Sleeve
MODELS:
All with Manual Transmission (except E31)
Situation:
Clutch release bearings with plastic sliding sleeves instead of aluminum were phased into production during 1992 on the above models.
Since November 1993, only clutch release bearings with a plastic sliding sleeve have been available through the parts department for the above models.
Action:
Clutch release bearings with a plastic sliding sleeve should NOT be greased.
If lubricant contacts the plastic sliding sleeve, wear particles and contamination will build up resulting in a considerable increase in clutch pedal effort.
Additionally, any residual grease on the guide sleeve must be removed when installing a clutch release bearing with a plastic sliding sleeve in place of a clutch release bearing with an aluminum sliding sleeve.
No lubricant is to be present when the release bearing has a plastic sliding sleeve.
