Guide Bearing — Checking and Replacing (Chevrolet Tahoe 1)

1. The pilot bearing is the support of the primary shaft of the gearbox and is pressed into the hole in the rear flange of the crankshaft. The condition of the bearing should be checked every time the clutch is removed. If there is any doubt about the condition of the bearing, it should be replaced. When removing the engine or gearbox, the bearing must be changed without fail.

2. Remove the gearbox.

3. Remove the clutch.

4. Check the condition of the bearing by shining a light into the hole.

5. If damage is detected, press out the bearing (see photo).



6. If you don't have a puller, remove the bearing using a hydraulic hammer. To do this, fill the recess in the crankshaft with thick grease, carefully removing the air, and hit the mandrel inserted into the bearing. The diameter of the mandrel should be slightly smaller than the inner diameter of the bearing (see photo). Remove the bearing and remove all grease.



7. Press in the new bearing, filling it with grease. The bearing seal should be facing outward (see photo).





8. Install the clutch and gearbox.
