Clutch Pilot Bearing

Sealed pilot bearing.

The clutch pilot bearing is a ball, roller, or brass bushing that centers the transmission's input shaft in the crankshaft flange.

Clutch pilot bearing location and function.

It reduces friction caused by the rotating crankshaft as the input shaft slows.

Clutch pilot bearing diagnosis.

A faulty pilot bearing is loudest when the clutch pedal is fully depressed and the clutch is disengaged. The input shaft and the crankshaft flange are now rotating at different speeds. They produce a squeal or grinding sound when the clutch is disengaged.

Clutch kit with a pilot bearing.

Pilot bearings are inexpensive and often replaced when disc replacement. If faulty, the transmission is separated from the engine. They can be difficult and usually require a special puller to remove. Use the appropriate driver, and tap on the outer race only.
