Should you replace a pilot bearing when doing the clutch?

Due to the amount of time involved and the fact that the transmission must be removed in order to replace the clutch assembly, most technicians will recommend replacing all of the components of the clutch assembly - the clutch disc, pressure plate, release bearing, and pilot bearing - at the same time. Many clutch assembly kits include a new pilot bearing.

Can I drive with a worn pilot bearing?

While it may be possible to drive with a bad or worn clutch pilot bearing, sometimes for a long while, it is not advised that you do so. The clutch assembly is the connection between your engine and your manual transmission. The pilot bearing allows the crankshaft to spin independently of the transmission input shaft when the clutch is disengaged. It also keeps the shaft centered properly. If the bearing fails, your clutch will not work as it should and damage can occur to your transmission.

Is a pilot bearing and a throwout bearing the same?

The pilot bearing and the throwout bearing are both components in a clutch assembly, but they are not the same component. The pilot bearing connects the engine crankshaft and the transmission input shaft, allowing them to rotate independently of one another when the clutch is disengaged. The throwout bearing, more formally known as the “release bearing”, is used to help disengage the clutch.
