ONLY THE STENNER FAN BRAKE TOOL SHOULD BE USED
FOR THIS STEP.
a.
Insert the fan brake tool into the vent in the rear of the motor housing. Refer
to the figures below.
NOTE: The fixed output pump doesn’t have a clutch so the fan brake keeps
the shaft from rotating when expanding the roller assembly.
b.
Holding the pump securely, use the cover as a wrench and quickly (snap)
rotate the roller assembly clockwise to expand the roller assembly. The tube
will be pressed against the tube housing wall.
