  Q: What is the purpose of the clutch pilot bearing and how should it be inspected and replaced for Chevrolet Colorado and GMC Canyon?

  A: The clutch pilot bearing is pressed into the rear of the crankshaft. It is greased at the factory and does not require additional lubrication. Its primary purpose is to support the front of the transmission input shaft. The pilot bearing should be inspected whenever the clutch components are removed from the engine. Due to its inaccessibility, if you are in doubt as to its condition, replace it with a new one. If the engine has been removed from the vehicle, disregard the following steps that do not apply. Remove the transmission. Remove the clutch components and the flywheel. Inspect for any excessive wear, scoring, lack of grease, dryness or obvious damage. If any of these conditions are noted, the bearing should be replaced. A flashlight will be helpful to direct light into the recess. Removal can be accomplished with a slide hammer fitted with a puller attachment, which are available at most auto parts stores or equipment rental yards. To install the new bearing, lightly lubricate the outside surface with multi-purpose grease, then drive it into the recess. A socket with an outside diameter slightly smaller than that of the bearing can be used. Drive it in to a depth of 0.457-inch. Be careful not to let the bearing become cocked in the bore. Install the clutch components, transmission and all other components removed previously, tightening all fasteners properly.
