(3) Upper drum ass’y
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).

<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).
