Pilot Bearing / Bushing Replacement in Spokane

The pilot bearing or pilot bushing sits in the center of the crankshaft flange and supports the tip of the transmission input shaft. It allows the input shaft to spin at a different speed than the crankshaft when the clutch is disengaged, such as when the vehicle is in neutral with the engine running. A worn pilot bearing causes noise, vibration, and in severe cases can prevent smooth clutch disengagement. Clutchland replaces pilot bearings and bushings at our North Spokane shop during clutch service.

Pilot bearings are typically sealed ball bearings, while pilot bushings are bronze or sintered-metal sleeves pressed into the crankshaft. Both wear over time as the input shaft rotates within them. Symptoms of failure include a grinding or whirring noise when the clutch is fully depressed and the transmission is in neutral, or difficulty shifting into gear because the input shaft is not spinning freely.

Spokane's cold winter starts and frequent clutch actuation in hilly stop-and-go traffic increase pilot bearing wear. The bearing sees the most differential rotation during extended idle with the clutch depressed, which is common when waiting at Spokane's longer traffic signals or warming up the vehicle on cold mornings. Over time the internal races pit and the bearing develops play.

Replacement involves pulling the old bearing or bushing from the crankshaft bore using a slide hammer or bearing puller, cleaning the bore, and pressing or driving the new bearing into place to the correct depth. We include pilot bearing replacement in every clutch service because access requires full clutch removal and the part cost is negligible.
