Adjusting belt tension
Note:
To allow for easier insertion of the new pulley shaft, it is recommended to adjust the belt tension.
A) Mark the present position of the upper rail box on the track.
B) Loosen the set screw (use 5/64 in. hex wrench) and slide the upper rail box assembly as
shown to adjust tension.
C) Once the new pulley shaft is installed, return the upper rail box to its original tension position
by aligning it with the mark, created in Step A. Next tighten the set screw.
