� Undo the screw (Pos. 50210), press the R/P head assy
(Pos. 50200) in the direction of the arrow as shown in Fig. 8.36 and
remove it upwards.
Note: Align the hole U of the R/P head assy (Pos. 50200) and pin
V on the mechanism chassis.
Subsequently, adjust the tape path and tracking position
(X value, refer to point 9. aAdjustmentsO).

Note:On reassembling the rotor (21000) the phase must be
adjusted to that of the headwheel. The hole W of the
headwheel and the hole X of the rotor (21000) must be on
the same side as shown in Fig. 8.39.
Tighten the screws (30000) for attaching the rotor (21000)
and the stator (22000) using a torque of 2.5 to 3.5kg/cm.

� When turning the mechanism upside down now, the carbon chip
(11500) will fall out (Fig. 8.37).
� Undo two screws (30000) and remove the rotor (Pos. 21000, Fig.
8.37).
� Undo the three screws (10400) at the bottom of the mechanism and

Refitting: When refitting the tape drum (11000) align it to match withX
the two dowels Y of the mounting base on the mechanism
chassis (Fig. 8.38).
Tighten the screws (10400) using a torque of 3.9 to
4.2kg/cm.Fig. 8.39
