There are a lot of components that have to work perfectly in order to get the right function out of your clutch. Most people only think about the clutch disc when they begin to have a problem in their shifting, but oftentimes, the problem lies in one of the other parts. Frequently, the failure is in the pilot bearing. The pilot bearing, also known as a release bearing or a throwout bearing, allows the clutch components to spin on the shaft while keeping the piston shaft of the slave cylinder stationary. When the pilot bearing begins to fail, you will experience a rumbling in your clutch and imperfect engagement. Once you begin to experience these symptoms, you should replace the bearing immediately with a Sachs Pilot Bearing. Sachs manufactures clutch components for over 500 automakers, so you can be certain that you getting a quality part in the Sachs Pilot Bearing. Because repairing a clutch is such a time consuming job, when one part fails, you should just go ahead and replace the entire clutch system. That is why the Sachs Pilot Bearing is offered as part of a larger Sachs Clutch Kit. In addition to the Sachs Pilot Bearing, the clutch kit will contain a replacement clutch disc, pressure place, and clutch alignment tool.
