Repairs On The Cam-Shaft Assembly - Kodak Instamatic M Series Repairing

REPAIRS ON THE CAM-SHAFT ASSEMBLY

Other than cleaning and lubrication, there's only one repair
you'll normally make on the in-and-out cam—replacing the
bushing, Fig. D69. Remember, the plastic bushing at the
front of the in-and-out cam deteriorates with age and
humidity.
Earlier we mentioned that there are two different styles of
bushings. The early model bushing has one shoulder; the
late-model bushing has two shoulders, Fig. D70. You can
only get the late-model bushing (part #177874). But if the
projector you're repairing has the early style, you can make a
modification to use the later style.
FIG. D70 The late-model in-and-out cam (top)
and the early model (bottom). Note the
difference in the bushings and the shoulder at
the center of the early style in-and-out cam.

FIG. D69 Front of the in-and-out cam; the
followers have been removed.
Remove the E-clip and washer holding the lever assembly to
the front of the in-and-out cam, Fig. D69. Remove the lever
assembly, Fig. D69. You can now clearly see if you have the
early style or late-model parts. Again, if you have the late-
model parts, the bushing has two shoulders, Fig. 70 (top).
Also, the front of the in-and-out cam has no raised shoulder
around the center hole. You can then use the replacement
bushing as is—there's no modification required.
Fit the replacement bushing to the lever assembly as shown
in Fig. D72 and Fig. D73. The shoulder with a larger
diameter faces the in-and-out cam; the longer shoulder has a
smaller diameter and faces the E-clip, Fig. D70.
But the early style in-and-out cam has a raised shoulder
around the center hole, Fig. D70 (bottom). Because of the
raised shoulder on the in-and-out cam, the bushing has only
one shoulder—the shoulder that fits through the lever
assembly and faces the E-clip. Now it's necessary to modify
both the bushing and the in-and-out cam.
FIG. D71 Variation—this is the center of the in-
and-out cam in the M85, a single-speed
projector. Use the two-shoulder bushing as it's
supplied. No modification is necessary.
