6. Reposition the mandrel and bushing and press out the opposite cup.
7. After removing the glasses, clean the fork thoroughly.
8. Place grease in the new cups to prevent the needles from falling out during assembly.

11. Insert the crosspiece into the bearing, insert the opposite bearing.
12. Carefully, without damaging the seals, press in the bearings, aligning them with the crosspiece journals.
