APERTURE PLATE ADJUSTMENT
(continued)
Horizontal travel of the aperture plate is also adjustable. The inboard
stop is set by loosening the clamping screw (A) and rotating the slotted end of
the slide shaft (B) to position the snap ring (C) at the desired stop point.
Secure the clamping screw (A) after the adjustment is correct. The outboard
stop is fixed by tightening or loosening stop screw (D) against the aperture
slide bracket. Secure lock nut (E) after the outer stop adjustment is correct.
GEAR COMPARTMENT COVER REMOVAL
Remove the gear compartment cover only when absolutely necessary,
and only after the machine has been at rest for at least (10) minutes to allow all
oil to drain into the reservoir. Remove the cover fastening screws. Make
certain no foreign material deposits in the gear compartment while the cover
is removed. Before replacing the cover, wipe all oil from the cover gasket and
the mating surface on the projector main frame. Any oil remaining on these
surfaces will provide an oil seepage path after the cover is replaced. Tighten all
screws equally and in sequence, and secure enough to form an oil-tight seal.
INTERMITTENT MOVEMENT REPLACEMENT
1.
Open the film gate. Rotate the framing handle fully clockwise.
2.
Set the shutter adjusting knob in mid-position. The shutter adjusting knob travels three complete turns.
To locate mid-position, rotate the knob to either stop, and reverse 1½ turns.
3.
Remove the gear compartment cover (see above).
4.
Rotate the vertical shaft until the intermittent drive gear mounting screw is visible. Remove the mounting
screw and slide the gear downward.
5.
Loosen the (2) intermittent retaining clamp screws on the framing cam and position the clamps to clear the
intermittent case.
6.
Withdraw the intermittent assembly from the gear compartment side, taking care not to strike the inter-
mittent oil feed tube positioned above the intermittent assembly.
7.
Slide the replacement intermittent movement into position. The keyway in the intermittent case is aligned
with the key in the framing cam. Press firmly to seat the O-ring.
8.
Rotate the intermittent retaining clamps to retain the intermittent assembly and tighten the fastening
screws securely.
9.
Rotate the shutter counterclockwise (from the rear of projector) until its leading edge is exactly in line
with the upper edge of the picture aperture (aperture just completely blocked).
10. Rotate the intermittent flywheel until the intermittent sprocket turns clockwise; (1) of the (4) index lines
on the outboard collar will align with the index line on the outboard bearing support arm.
11. Continue to rotate the flywheel in the same direction until the intermittent sprocket just begins to move.
12. Reverse rotation of the flywheel until the sprocket stops. Then, rotate the flywheel counterclockwise
until the start of sprocket rotation is felt.
13. Continue to rotate the flywheel until the precise point at which the sprocket is about to move is reached.
Retain that setting.
14. Raise the intermittent drive gear and rotate it tooth by tooth until it meshes with the intermittent driven
gear. At this time, the mounting hole in the drive gear should align with the hole in the vertical shaft. Do
not rotate the vertical shaft or driven gear. Replace the gear mounting screw.
15. Align the intermittent sprocket with the film trap (see below).
