As the linings wear in, the rotating shaft will move up the cam slot and around the corner of
the cam noted above (Figure 7), and the connecting arms (see Figure 1) will move up the side
wall and begin to match or line up with the wear-in line marked on the side wall.
Note that it may take several car runs to complete lining wear-in.
Once the rotating shaft has turned the corner and the wear-in line is matched or covered, stop
the car and

cause unsafe conditions.
If the lining wear-in is not completed after the grooves in the linings have reached
approximately 1/16" (1.5 mm) deep, spacer shims (see Figure 8 below) can be moved from
between the shaft support blocks and moveable shoe to the outside of the support block to
allow the rotating shaft to just turn the corner and move up the cam to near the wear-in line.
Refer to Table 2 on page 7 for initial spacer and shim set-up. Note: Before changing
spacers, install security set screws to prevent unintended "ROPE GRIPPER™"
activation, which could lead to severe personal injury and/or damage to the unit.
