Center distances of the pulleys
Center distance ”a” (Fig. 5) must be set as given in Tab. 2. Take care that the wide section
V-belt does not protrude over the edge of the pulley face, and also that it does not run onto
the central hub of the movable pulley flange. The limits must be set by the stops/locking
nuts that are provided on the adjusting spindle.

Note!
When replacing the belt, check the limits and reset them, if necessary, because
the belts have a certain amount of tolerance.
