3. Remove O-rings from solenoid valves and terminal body.
4. Place control valve upper body facedown, and remove bolts b ,
and nut f .
CAUTION:
Remove bolts with control valve upper body facing down,
because control valve upper body and control valve inter
body may come off and steel ball may fall and be lost.
5. Remove control valve lower body from control valve inter body.
6. Turn over control valve lower body.
7. Remove bolts e , separating plate and support plates from con-
trol valve lower body.
8. Remove check balls and oil cooler relief valve springs from con-
trol valve lower body.
CAUTION:
Be careful not to lose check balls and oil cooler relief valve
springs.
