CAM FOLLOWERS
FIG. D45 Up-and-down cams at the end of the
shutter-drive shaft.
8. In Fig. D45, you can see the cams on the shutter-drive
shaft. These cams—one for super 8 and one for regular 8—
drive the claws up and down (the in-and-out cam, you'll
recall, drives the claws in and out). Turn the shutter shaft
counterclockwise (as seen from the pulley end) until the two
cams are parallel to the cam followers on the claws, Fig.
D45. Then pull out the shutter-drive shaft, Fig. D46.
C AUTION: A coil-type (compression) spring fits over
the end of the shutter-drive shaft, Fig. D48. The spring
will be loose when you lift out the shutter-drive shaft.
V ARIATION: If the projector just runs super-8 film,
there's only one cam at the end of the shutter-drive shaft,
Fig. D49.
9. Lift out the shutter, Fig. 49. Watch for loose washers.
NOTE: There should be a washer between the shutter and
the shutter-shaft bearing that's still in the mechanism. You
may find additional washers on the shutter-drive shaft. But
only one washer is needed. Save any additional washers for
spare parts—the washers are no longer available from
Kodak. And if you lose the washer? Keep searching. As
you'll see in a moment, the washer is important.
C AUTION: The cam followers for the up-and-down
claw movement are now loose, Fig. D45. The cam
followers can come off the claws once you remove the
shutter-drive shaft. Fig. D52 shows the same view as Fig.
D47, but we've removed one of the cam followers.
10. To make reassembly a little easier, also remove the rear
bearing (shutter side) for the shutter shaft, Fig. D50 (just
