9. Steering head bearings: examination and renovation

  1. Clean and examine the outer bearing tracks whilst in the steering head. Since the forks rotate through only a small angle, the commonest damage to the bearings is brinelling. This is indenting of the roller tracks by the rollers, generally due to maladjustment. It can be felt, when turning the forks, by the steering seeming to 'index' in one position.
  2. Check the rollers and their cages for signs of wear or damage and renew the complete bearing if in doubt about its condition.
  3. Always renew any dust seals or other sealing components to prevent the entry of dirt.
