25/KODAK M-SERIES PROJECTORS
Once you've installed the two followers, check the operation
of the unit. Turn the pulley of the cam shaft in a counter-
clockwise direction, Fig. D84. Now the claws should move
in and out as well as up and down.
NOTE:
While you were working on the mechanism, the
mask spring shown in Fig. D85 may have come out. The
mask spring operates the regular-8/super-8 changeover mask
in the aperture. To replace the spring, remove the still-frame
lever, Fig. D87. Fig. D86 shows the spring installed. Use
your tweezers—and summon all your patience and dexterity.
REPLACING THE DAMPING ARM
There's one more repair to complete before you replace the
mechanism in the housing—replacing the damping arm, Fig.
D88. It's quite common for the plastic damping arm to be
broken in an old projector. Again, age and humidity make
the plastic brittle. You then have the bare spring and roller—
and possibly part of the old damping arm, Fig. D89.
The film passes over the damping arm. When you load the
film, push down the damping arm until it latches in the down
position (the damping arm does not latch with all models).

Then, when the film starts running through the projector, the
latch holding the damping arm disengages. The damping arm
automatically springs up to put spring tension against the
film—tension that smooths out (or
dampens
) the film
movement through the film gate.
Replacement damping arms are made for the M-series
projectors by an independent manufacturer. Keep the spring
and roller section of the old damping arm. Just install the
new plastic section on the spring/roller section.
We'll first remove the spring/roller section of the old
damping arm. Remove the cover screw indicated in Fig. D88.
Just loosen the other two cover screws. The projector may
