3.2.10.2 How to install (Phase matching)
(1) Make sure that the mark E of the control plate is in align-
ment with the mark of the loading arm gear shaft and
bring the guide marks on the rotary encoder into alignment
as indicated in Fig.3-2-10a. (See Fig. 3-2-10a and Fig. 3-2-
10b.)
(2) Turn over the rotary encoder with its guide marks kept in
alignment and install it by fitting on the shaft of the rotary
encoder guide and the positioning pin.
(3) Tighten the screw (A) to complete the installation.
3.2.11 Clutch unit
(1) Remove the belt wound around the capstan motor and the
clutch unit.
(2) Remove the slit washer and remove the clutch unit.

3.2.12 Change lever assembly, direct gear, clutch gear and
coupling gear
3.2.12.1 How to remove
(1) Release the two lugs of the rotary encoder guide in the ar-
row-indicated direction and remove the change lever as-
sembly.
(2) Remove the slit washer retaining the direct gear and re-
move the latter.
Take care so as not to lose the washer and spring. (See

3.2.12.2 How to install
(1) Install the clutch gear, spring (A), spring (C), direct gear,
spacer and others to the individual shafts of the main deck,
and finally the slit washer. (See Fig.3-2-12a.)
(2) Let the spring (B) drops into the rotary encoder guide hole
and install the change lever assembly.(Take care not to
mistake a direction of the spring.) The point is to slightly lift
the coupling gear and catch it from the both sides with the
assembly. (See Fig.3-2-12b.)
