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.
