Place a soft-metal (i.e. brass) bar against the fl ange of the Taper-Grip® bushing and
carefully strike end of bar with a hammer to release the bushing.

Apply a liquid penetrant to the shaft where it contacts the bushing. Allow time for
the liquid to settle between the shaft and the bushing wall. Once the penetrant has
settled adequately, carefully remove the Cyclo® BBB4 from the driven shaft.
If the Taper-Grip® bushing releases but the unit cannot be removed from the driven
shaft, a puller may need to be applied to the bushing fl ange to pull the unit free
from the shaft.
