1)
Disconnect the connector on the “ASSY, MOTOR STEP-
PING
(4K000)
”. (Refer to Fig. 3-6-1.)
2)
Remove the two “NUT HEX 3
(4L000)
” ((A) and (B)) and
remove the “ASSY, MOTOR STEPPING
(4K000)
”. (Re-
fer to Fig. 3-6-1.)
NOTE: Take care not to lose the “SPECIAL WASHER-
4X0.3
(4P000)
” when removing the “NUT HEX 3
(4L000)
”.
Take care not to lose the four “GASKET, O RING(D2.8)
(4M000)
” when removing the “ASSY, MOTOR STEP-
PING

”.
ASSEMBLY NOTES:
1.
Referring to Fig. 3-6-2, install the “ASSY, MOTOR STEP-
PING
(4K000)
” according to the following procedure.
a. Hook the “BELT, MOTOR STEP
(4J000)
” to the
“ASSY, MOTOR STEPPING
(4K000)
” and tighten the
two “NUT HEX 3
(4L000)
” at the point where the
“BELT, MOTOR STEP
(4J000)
” stretches tightly.
b. Referring to section 3-7, confirm that the adjustment
tension value of the “BELT, DRUM
(4I000)
” is correct.
c. Rotating the “PULLEY, DRUM
(4F000)
” clockwise,
rotate the “BELT, MOTOR STEP
(4J000)
” more than
one revolution.
d. Set the Ruler (VJ8-0228) along the “BELT, MOTOR
STEP
(4J000)
”, confirm that the pressure welding
value is [0.34N±0.15N] when pressing the Dial Ten-
sion Gauge DTN-100G (VJ8-0227) until the play in the
“BELT, MOTOR STEP
(4J000)
” is 0.5mm. The mea-
suring position and the direction of pressure on the
“BELT, MOTOR STEP
(4J000)
” are shown in Fig. 3-
6-3.
e. If the pressure welding value is not [0.34N±0.15N],
loosen the “NUT HEX 3
(4L000)
” (B) and fine-adjust
the “ASSY, MOTOR STEPPING
(4K000)
”, then re-
tighten the “NUT HEX 3
(4L000)
” (B) again.
f.
Repeat steps c, d, and e above until the pressure
welding value is within [0.34N±0.15N].
