Guide Bearing — Checking and Replacing [Toyota Land Cruiser J60]

The ball guide bearing is the support for 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, the bearing must be changed without fail.

Check and replace

1. Remove the gearbox.

2. Remove the clutch.

3. Wipe off the grease and check the condition of the bearing by shining a light into the hole.



4. If damage is found to the nose of the primary shaft, or if rotation is difficult, press out the bearing.

5. If you do not have a puller, remove the bearing using a hydraulic hammer.



6. To do this, fill the recess in the crankshaft with thick grease, carefully removing the air.





7. Hit the guide mandrel inserted into the bearing. The diameter of the mandrel should be slightly smaller than the inner diameter of the bearing.

8. Remove the bearing and remove all grease.



9. Press in the new bearing using a mandrel resting against the outer race.

10. Install the clutch and gearbox.
