(3) Upper drum ass’y
(Both common type)
Remove the upper drum
ass’y from the lower drum
ass'y as shown in Figure 3.
At this time take care so as
not to lose the gap shim.
In this state put the motor rotor on the upper surface of upper
drum ass'y, and tighten the mounting screw. At this time make
sure that the head screw in the three places is visible through
the motor rotor hole (Figure 8). The screw tightening torque
must be 0.1N·m (1 kg·cm).
Figure 7
<Installation>
Install the upper drum in the reverse order of removal.
(1) Balancer
Mount the balancer to the upper drum ass'y with the balancer mounting screw. The screw tightening torque must be 0.1N·m
(tighting torque 1kg·cm). (Figure 5)
(2) Motor rotor, rotary transformer rotor ass’y
Clean the contact surfaces of rotor ass’y holder and upper drum ass'y, and ascertain that there are no contamination and flaws.
Next, adjust the phase so that the positioning pin of rotor ass'y is inserted into the positioning hole of upper drum, and tight fit the
rotor ass'y to the lower surface of upper drum ass'y (Figure 7).
(4)-a Motor rotor ass'y and ro-
tary transformer rotor
ass'y
(former type)
Remove the 2 rotor
mounting screws as
shown in Figure 4-a, and
remove the motor rotor
and the rotary trans-
former ass'y.
(4)-b Motor rotor ass'y
(bonded type)
Remove two screws fix-
ing the rotor as shown in
Figure 4-b, then remove
only the motor rotor.

(5)-a Balancer
(former type)
Remove the balancer

shown in Figure 5, and
remove the balancer.
(5)-b. Balancer
(bonded type)
For the bonded type of
drum, the balancer can-
not be removed.
(6) Lower drum ass'y
(Both common type)
Remove the FPC mounting
screw from the lower drum
ass'y as shown in Figure 6.
