Removing The Sprocket - Minolta XD-11 Repair Manual

the lock plate, a part under the transport
cam. Just to be safe, you might discon­
nect and remove the
spring.
Now lift out the transport cam together
w ith the mirror-cocking lever and the
shutter-cocking lever. Fig. 122 points out
the lock plate mentioned earlier. The
downward-projecting tab on the lock
plate comes against the end of the wind
latch.
Lift out the lock plate. Then, from the
top of the body casting, lift the wind shaft
high enough to disconnect the end of the
wind-shaft spring. As you lift out the
wind shaft, watch for the loose bushing
that fits into the top end of the take-up
spool. Fig. 123. The bushing normally
stays w ith the wind shaft as shown.
To remove the take-up-spool assembly,
Fig. 123, you must first take out the
winding-base plate, Fig. 122. Remove the
tw o screws. Then lift out the winding-
base plate, the assembly that contains the
tw o wind gears and the latches.
The take-up-spool gear may stay on the
underside of the winding-base plate. Or it
may stay in the bottom of the body
casting. Two tabs on the underside of the
take-up-spool gear engage the slots in the
take-up-spool shaft. Lift out both the
take-up-spool gear and the sprocket gear
at the bottom of the body casting. W atch
for a washer on top of the sprocket gear.
You can now remove the take-up spool
from the back of the body casting, Fig.
123. The take-up spool has three sections
— the center shaft which includes the slip
spring, the plastic spool (the section that
breaks), and the bearing which
shoulder up on top of the plastic spool.
W hen you order a replacement, you'll get
both the plastic spool and the center
shaft.

REMOVING THE SPROCKET

To take out the sprocket, first remove
the counter-advance assembly, Fig. 124;
the base plate of the assembly also serves
as the upper bearing for the sprocket.
Removing the counter-advance assembly
loses the timing of the counter actuator,
the black rod running through the bush­
ing of the back-sensing lever.
The camera back pushes the back-
sensing lever counterclockwise. As a
result, the back-sensing lever brings the
counter actuator against the gear on the
underside of the counter dial. As the
sprocket rotates, it turns the counter ac­
tuator. Then, when the notch in the
counter actuator comes
counter-dial tooth, the counter dial ad­
vances one film-frame calibration.
Since the sprocket drives the counter
