IMPORTANT NOTE
The cam grooves or tapered gibs (Item 477) need to be
adjusted during assembly.
Cam groove or tapered gib adjustment
The cam groove or tapered gib on the right side (Item 477)
is not adjustable. The cam groove on the left-hand side
is to be adjusted by the screws (Item 479) located next to
the slide bar (Item 477). The cam grooves are properly ad-
justed when the slide plate (Item 472 or 474) is allowed to
move freely through its complete range.
A. Remove the handwheel assembly nut (Item 465) and
handwheel (Item 462) before making adjustment.
B. Clean sliding surfaces of the slide plate and cam grooves,
and then re-apply a molybdenum-based anti-seize com
pound to these surfaces.
C. Assemble the motor and/or c-face adapter to the slide-
plate (Item 472/474) by re-installing the motor bolts.
Apply a thread-locking agent to the screw threads
during
assembly.
D. Place the non-adjustable (right-side) cam groove onto
the slide plate and tighten the socket head setscrews
(Item 478). Apply a thread-locking agent to the screw
threads during assembly
E. Place the intermediate housing (Item 447) onto the
slide plate (Item 472 or 474) and then install the adjust-
able (Left-side) cam groove (Item 477).
F. Install the socket head screws (Item 478) and the adjust-
ment setscrews (Item 479). Apply a thread-locking
agent to the screw threads during assembly. Do not
completely tighten either set of screws – follow Steps 7
& 8!
G. Adjust the cam groove set screws (Item 479) so that
there is minimal side-play or side-movement and be
certain that the friction drive housing (Item 447) can
move
freely.
H. Then, tighten the socket head setscrews (Item 478).
I. After completing the adjustment of the cam grooves
(Item 477) the handwheel (Item 462) and handwheel
assembly nut (Item 465) can be re-installed.
J. Re-assemble the driving disc and re-connect the driving
