shaft groove.
NOTE: Securing the slotted nut: Swage the retaining edge
of the adjusted slotted nut into the longitudinal groove of the
shaft by means of a rounded mandrel. The retaining edge
must be deformed evenly into the longitudinal groove until it
is in contact with the mid-section of the groove bottom. The
retaining edge must not tear. If necessary, it should there-
fore not be swaged entirely to the bottom of the groove.
(Groove width - mandrel dia. Approx. 2 mm).
5. Place the spur gear (1) on the centering of the
flanged shaft. Mount the gear with new cap screws

a crowbar or large screwdriver to hold the gear in
place while tightening the cap screws.
NOTE: For safety reasons, new M12 cap screws must be
used for assembly.
