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.2-2-12a.)
(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.2-2-12b.)

1. How to remove
(1) Release the two lugs of the rotary encoder guide in the
arrow-indicated direction and remove the change lever
assembly.
(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
Fig.2-2-12a.)
2.2.10 Rotary encoder
1. How to remove
(1) Remove the screw (A) and remove the rotary encoder
by pulling it up. (See Fig. 2-2-10a.)

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 align-
ment as indicated in Fig.2-2-10a. (See Fig. 2-2-10a and
Fig. 2-2-10b.)
(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.

Note:
• The parts with marked (

) have different types of mechanisms (standard type or high-
speed FF/REW type).
*
1 : Uses the standard type mechanism only.
*
2 : Uses the high-speed FF/REW type mechanism only.
