INTERMITTENT SPROCKET REPLACEMENT
1.
Remove the film gate runner. Dismount the film trap. Open the intermittent sprocket pad arm.
2.
Rotate the framing knob to its extreme clockwise position to expose the intermittent sprocket film stripper
mounting screw. Remove the screw and stripper.
3.
Turn the projector mechanism by hand so that one of the collar index lines (A) aligns with the index mark
on the outboard arm (B), and the sprocket mounting screw is exposed.
4.
Remove the intermittent sprocket mounting screw and nut.
5.
Loosen the (2) intermittent outboard collar set screws and remove the collar (C).
6.
Remove the (2) outboard arm socket head mounting screws and dismount the outboard arm (D).
7.
Remove the worn intermittent sprocket. Slide the replacement sprocket onto shaft.
8.
Position the intermittent outboard bearing arm (D) on the intermittent sprocket shaft and start the (2)
socket head mounting screws finger tight. Adjust the bearing arm, as required, so that the bearing is
precisely centered with respect to the intermittent shaft. Tighten the (2) mounting screws.
9.
Fasten the replacement intermittent sprocket to the intermittent shaft using the screw and nut supplied.
10. Slide the intermittent outboard collar (C) onto the intermittent shaft and align one of its index lines (A) to
the index mark on the outboard bearing arm (B). Pull the intermittent sprocket
out
while pressing the
outboard collar
in,
so that shaft end play is just perceptible.
11. Securely tighten the (2) set screws in collar (C). Check that the
shaft end play is just perceptible.
12. Replace intermittent sprocket film stripper.
13. Align the intermittent sprocket (see below).
14. Replace film trap and install the film gate runner.
INTERMITTENT SPROCKET ALIGNMENT
Loosen the intermittent sprocket fastening screw and slide the sprocket, as required, until the outside face
of the sprocket is flush with a straight edge (i.e. machinist’s steel pocket ruler) placed on the outside face of the
lower holdback sprocket. Securely tighten the intermittent sprocket fastening screw. Thread a length of scrap
film through the trap between the upper sprocket and the intermittent sprocket to verify correct alignment.
FRAMING LIGHT REPLACEMENT
Remove the film trap. Dismount the L.E.D. Printed Circuit Board assembly from the trap plate (three
screws); replace with new unit (Part No. 52-00353). Align the pins of the electical connectors and slide the film
trap in so that it registers with the (2) dowel pins in the main frame; secure the captive mounting screw.
FEED AND HOLDBACK SPROCKET PAD ROLLER ADJUSTMENT
For coarse adjustment, loosen the three socket head mounting screws securing the pad roller assembly to
the main frame. Position the pad roller assembly so the rollers are at an equal distance from the face of the film
sprocket. Secure the three screws.
For fine adjustment, loosen the socket head screws securing the roller shafts to the roller arm. The shafts
are eccentric; rotating the shaft will move the roller closer to or farther from the sprocket face. Rotate each
roller shaft to position each roller (2) film thicknesses from the face of the sprocket. If the roller cannot be
placed at this position, reset the coarse adjustment. Secure the shafts after reaching the correct setting.
