Also known as EBG-8639 / 46AX534, it sits in the flywheel or crankshaft bore and supports the transmission input shaft, reducing friction when the clutch is disengaged. A worn or dry pilot bearing can cause noise, vibration, and transmission input shaft damage, so it is commonly replaced during clutch service. The bearing crosses to many other makes including Caterpillar, Cummins, Eaton/Fuller, Kenworth, Navistar, Volvo, and Renault applications.
