5.5.3 Replacing Rollers, Tension Springs, and Cable Carrier Links
Refer to “Figure 5-29 Rollers and Tensioning Spring”.
1. The rollers can be removed one at a time by removing the screw (4mm hex key) at their hub and pulling off
the roller and bearing. When reinstalling, torque the screws to 45 in. lbs (reference).
2. To replace the roller tensioning spring, first use pliers to pull the tension spring off the roll pin at the end of
the lift rail. Then take off the 2 center rollers and slide the tensioning plate out of the lift rail. Remove the old
spring.
3. Reinstall the 2 center rollers. Use a hex key in the center access slot to lift the tensioning plate up so that
you can screw the rollers into the holes in the plate. Torque the screws to 45 in. lbs (reference).
4. Using pliers, pull the tensioning spring up onto the roll pin at the end of the rail.
5. Individual links of the flexible cable carrier snap out of the belt by unfolding them from their center. To
replace the link that fastens the carrier to the channel, drill out the rivet and replace it with a M3 x 8 screw.
