  Q: What is the purpose of the clutch pilot bearing and how should it be inspected and replaced on Chevrolet Blazer,S10,GMC Jimmy and Sonoma?

  A: The clutch pilot bearing is a needle roller-type bearing that supports the front of the transmission input shaft and is pressed into the rear of the crankshaft. It does not require additional lubrication as it is greased at the factory. When removing the clutch components, it is important to inspect the pilot bearing for excessive wear, scoring, dryness, roughness, or any other damage. Removal can be done using a special puller or by using a solid steel bar, wood dowel, or socket with a fixed bolt. The bar should fit snugly into the bearing. Before installation, the bearing and the area behind it should be packed tightly with heavy grease to eliminate air. To install the new bearing, lightly lubricate the outside surface with grease and use a soft-face hammer to drive it into the recess. Some bearings may have an O-ring seal that should face outwards. Finally, reassemble the clutch components, transmission, and other previously removed parts, ensuring that all fasteners are tightened to the recommended torque.
