SERVO ADJUSTMENT
1. Completely remove all dirt and other materials adhered
around the
servo switch.
2. Remove the snap ring.
3. Remove the
servo switch.
4. To prevent rotation of the piston, engage the
of
the special tool into the notch of the piston, and using
the adapter, secure the piston as shown to the left .
Caution
1Don’t press in the piston with the special tool.
2.When mounting the adapter on the transaxle case,
tighten it by hand. Do not overtighten.
5. Loosen the lock nut to before the V-groove of the adjusting
rod, and tighten the special tool (inner) until it contacts
the lock nut.

6. Engage the special tool (outer) on the lock nut.
Rotating the outer cylinder counterclockwise and the inner
cylinder clockwise, lock the lock nut and special t ool (in-
ner).
7. Attach a torque wrench to the special tool (inne r) and
tighten to a torque of 10 Nm (7.2
and repeating
“Tighten” and “Loosen” two times then torque to 5 N m
(3.6
After that, back off the special tool (inner)
2 to
turns.
8. Engage the tool (outer) on the lock nut.
Rotating the outer cylinder clockwise and the inner cylinder
counterclockwise, unlock the lock nut and special ‘tool
(inner).
Caution
When unlocking the nut and special tool, apply equa l
force to both parts.

Caution
If it is rapidly tightened with the socket wrench o r
