• Special tools named: puller

Don't miss

• The internal puller may only be applied below the teeth and not close to the axial needle bearing.
• For re-installation, mark which axial needle bearing was clipped on at chamfer (arrow) on top of sun gear "„III“"(item 2).
• If necessary, the thrust washer can be made to come loose by blowing compressed air under it and pulling it off with a wire hook.
