T IP: Earlier we mentioned that you must remove the
mechanism to replace the damping arm. The damping
arm is now accessible. However, replacing the damping arm
should be your final repair before replacing the mechanism.
Why? With the mechanism removed, the damping arm is
exposed to further damage. If you replace the damping
arm—and then proceed to do further repairs on the mecha-
nism—you may accidentally break your new damping arm.
Before going through the procedure for replacing the
damping arm, let's look at the other repairs on the mecha-
nism.
CHECKING THE CAM BUSHING
The in-and-out cam, Fig. D35, runs on a plastic bushing—
the white bushing pointed out in Fig. D34. Replacing the
bushing is another normal repair in the projector. Again age
and humidity are the enemies. The plastic bushing deterio-
rates with age and atmospheric conditions.
Fig. D34 shows a bushing that has deteriorated. The brown
color (rather than white) is one indication of deterioration. In
Fig. D34, you can actually see that the bushing is breaking
up. Fig. D36 shows another obvious example—here the
bushing is completely missing. But if you're in doubt, use
the sharp point of your probe to push against the plastic
bushing, Fig. D37. If the bushing breaks up, it should be
replaced. Replacing a questionable bushing now may save
you a problem down the road.
There are two different bushings—an early style and a late-
model style. Only the late-model style is available as a
replacement part. However, as you'll see a little later, you can
adapt the late-model bushing for a projector with early style
parts.
