Adjustment Procedure
Results of Improper Adjustment
7) Adjustment of active tension (only the DDL-9000C-F)
1. Assembly
Assemble the active tension in the following way.
1). Sub assembly
Attach the screw (M4) ❸ to the plunger ❷ of the AT solenoid ❶.
At this time, keep 19 ± 0.1 mm from the upper surface of the
xed plate ❹ to the upper portion of the screw ❸ and a nut
torque of 25± 5kgcm.
(Cautions)1. Put the plunger ❷ in a state of being lowered.
2. Use the plunger ❷ that falls under its own
weight. Do not use a torque plunger.
2). Complete assembly
○ Positioning of the solenoid
Align the shaft center of the thread tension with that of the AT
solenoid ❶ at the time of attachment of the AT solenoid ❶.
(After assembling the thread tension, attach the AT solenoid ❶.
Check the shaft center instead of the surface portion.)
(Cautions)When the shaft center is out of alignment, the shaft
becomes worse at the time of pressurization with the
AT solenoid ❶ and the regular value becomes dif-
cult to come out.
○ Relation between the plunger and the (thread tension) disk.
Put the convex portion of the plunger ❷ in a state where it
comes out of the surface of the AT solenoid ❶ by 1.5 ± 0.1 mm.
Loosen the thread tension cap setscrew ❺ to press the thread
tension cap ❻ lightly.
Tighten the thread tension cap setscrew
❺
.
(Cautions) 1. Position the thread tension cap setscrew ❺ in
the right direction. When it is positioned on the
left side, there is a possibility that it interferes
with thread.
2. After assembly, press the plunger ❷ to make
sure that the thread tension disk does not move
(not revolve).
3). Conrmation of assembly quality
Make sure that the plunger ❷ returns smoothly at the time of
pressing it lightly.
When the plunger ❷ is OFF, make sure that there is a gap of 1
mm or more in the (thread tension) disk.
If the gap is not 1 mm or more, it becomes necessary to adjust
19±0.1mm as an assembly value.
