REPLACING ROLLERS
To replace rollers:
1. Using a retaining ring tool (Part Number 109852-CR), remove the
retaining rings from the ends of the roller axles and slide the rollers off.
Take care to avoid opening the retaining rings too wide.
2. Check to be sure that the wave washers are installed on the axles
against the rotor plate.
3. Slide the new rollers, Replacement Roller Kit 07584-02, onto the axles,
placing the ends with the flush bearing surface inward toward the rotor
plate against the wave washers, and the etched ends with the recessed
bearing surface outward toward the free ends of the roller axles.
4. Replace the retaining rings. You may have to push the rollers in to
compress the wave washers to allow the retaining rings to engage the
grooves in the axles.
