Notes:
1. In removing the D.D. stator assembly, part of the drum
earth spring pops out of the pre-load collar.
Be careful not to lose it.
2. Install, so that the D.D. rotor ass'y and upper drum ass'y
mounting direction check holes align.
(Align the upper drum dent with the rotor hole.)
3. Be careful not to damage the upper drum or the video
head.
4. Protect the hole elements from shock due to contact with
D.D. stator or D.D. rotor ass'y.
5. After installation adjust the playback switching point for
adjustment of servo circuit.

• Reassembly
1. Taking care so that the capstan shaft does not contact
the mechanism chassis, set its position on the mecha-
nism chassis, and then install with the three screws.
2. Install the slow brake lever.
3. Install the reel belt.
Notes:
1. Before installing the capstan D.D. motor, confirm whether
an acetate tape (ZTAPEN120020E) is drawn on the
back of mechanism chassis.
2. After installing the capstan D.D. motor, be sure to
rotate the capstan D.D. motor and check the move-
ment.
3. Set the tape, and check for the tape crease near the
reverse guide in the playback mode. Adjust the A/C
head and azimuth as stated in Page 20 Replacement
2. If crease is found, adjust as stated in Page 19
"HEIGHT ADJUSTMENT OF REVERSE GUIDE".
