3. Claw engagement. If the image jumps—or if the film
fails to move through the gate—it may be necessary to adjust
the depth of claw engagement. You can visually check the
claw engagement by looking through the lens opening while
transporting a roll of test film, Fig. D121. Proper claw
engagement—0.35 ±.005". The specification gives you an
idea for visually judging the engagement—or you can make
the special gauge suggested by Kodak (see, Operation and
Repair Tips from Kodak). For a quick test while running
film, pull up on the film before it passes through the gate—if
you can pull the film out of the gate, the depth of claw
engagement is insufficient. Check both with super 8 and with
regular 8.
Remember that the M80 projector uses different followers
for super 8 and regular 8. The followers come in different
lengths to adjust the claw engagement. Here's the rule:
To increase the depth of engagement,
use a shorter follower.
To decrease the depth of engagement,
use a longer follower.
To remove the follower, unplug the projector and then
remove the bottom cover. Locate the in-and-out cam, Fig.
D122. You can then find the two followers on the motor side
of the in-and-out cam—they aren't as easy to reach as when
you had the drive-cam assembly removed, but you can still
get to the followers.
As you're looking from the bottom of the projector, Fig.
D122, the super-8 follower is closer to the bottom of the
mechanism—it's the follower that's easier to reach. The
regular-8 follower is further in; it's more difficult to reach.
Use your hemostats to grasp the followers. Clamp the
hemostat on the follower you want to remove. Then use your
probe to lift the arm slightly. Remember—don't lift the arm
too far. Lifting the arm too far may allow one of the claw
ball bearings to fall out; it's then necessary to disassemble
the mechanism to replace the ball bearing. As you lift the
arm, slide the follower out of its hole.
Now use your caliper to measure the length of the follower.
To make the adjustment, you probably need the bullet that's
one size longer (if the claw engagement is too deep) or one
size shorter (if the claw engagement is insufficient).
Here are the lengths of available followers for the M80:
0.220" (part #176652)
0.225" (part #176653)
0.230" (part #176654)
0.235" (part #176655)
0.240" (part #176656)
0.245" (part #178373)
0.250" (part #178374)

Suppose, for example, that you have insufficient claw
engagement with super-8 film. You then know you need a
shorter follower. Let's say the old super-8 follower measures
0.230". In that case, you might try the 0.225" follower. If the
claw engagement is still insufficient, try the 0.220" follower.
Clamp the new follower in your hemostat. Again lift the arm
slightly with your probe—just enough to slide in the new
follower.
Fortunately, you'll rarely have to change the followers. If you
do need a shorter follower, you can always file a little off the
flat side. But if you need a longer follower, order one
according to the part number.
V ARIATION: If you're working on a model that just
runs super 8, there's only one follower. The follower is a
little different in shape (rather than looking like a bullet, it
looks more like a shift knob, Fig. D123), but the adjustment
is the same. Here are the followers for the M90 and M70:
