Locate the notch on the outer edge of the shutter (large
blade), and the timing mark on the in-and-out cam, Fig. D81.
The in-and-out cam may have several timing marks. You can
use any of the timing marks on the in-and-out cam. But
usually one of the timing marks is highlighted, making it
easier to see, Fig. D82.
Shift the in-and-out cam out of engagement with the shutter
gear. You can now turn both the in-and-out cam and the
shutter gear to change their positions. Re-engage the in-and-
out cam with the timing marks aligned as shown in Fig.
D82.
Note that the timing mark on the in-and-out can isn't actually
within the shutter notch. Rather the timing mark on the in-
and-out cam is one tooth clockwise of the shutter notch, Fig.
D82. Once you're sure that the timing is correct, tighten the
spring clamps over the cam-shaft bearings.
Next replace the nylon followers. Fig. D83 shows one
technique. Here we've clamped the follower in a hemostat.
We're then using the hemostat to lift the spring arm (the arm
with the hole for the follower) and simultaneously sliding the
follower into place. As the spring arm returns, the hole
passes over the follower.
Remember that it's critical to put the proper follower in the
proper position. One follower was individually selected to
control the depth of claw engagement for super 8; the other
follower was individually selected to control the depth of
claw engagement for regular 8. Prior to removing the
followers, you'll recall, we marked the super 8 follower (the
follower that's closer to the top of the mechanism and a little
easier to reach). In Fig. D83, we're installing the super-8
follower at the proper position.
C AUTION: Don't lift the spring arms any further
than absolutely necessary. You've seen that the
claws run on ball bearings. Lifting the spring arm may
cause a ball bearing to fall out.

of the in-and-out cam.
