2. Untie the cord at the front of the cover.
3. Remove the cover from the lever.
4. While holding the lever axis from turning with the second key, unscrew the axle mounting nut.
5. Please note: there is a spring washer under the nut.
6. Remove the lever shaft.
7. Take out the two plastic bushings.
8. Replace worn or broken bushings. Please note: plastic sleeves are split, which is not a defect.
