Valve Body

COMPONENTS

(Disassembly of Valve Body)




1. NOTE THE NUMBER OF ADJUSTING RINGS

HINT: Count the number of adjusting rings before disassembly of the valve body because the throttle pressure is changed according to the number. (Some of the valve bodies do not have any adjusting rings.)




2. NOTE THE POSITION OF PLUNGER SLEEVE
Note which step at the end of the plunger sleeve is in contact with the valve body.

HINT: Be certain to check this before disassembly because the line pressure changes according to the part of the plunger sleeve which comes into contact with the valve body.

3. SEPARATE NO.2 PRESSURE REGULATOR VALVE BODY




a. Remove the tube clamp and oil tube.




b. Remove the four bolts, No.2 pressure regulator valve body, gasket and plate from the upper valve body.




4. REMOVE O/D SOLENOID
a. Remove the solenoid.
b. Remove the O-ring from the solenoid.




5. REMOVE LOWER VALVE BODY COVER AND OIL STRAINER
a. Remove the seventeen bolts, cover, plate and two gaskets.
b. Remove the oil strainer.

6. SEPARATE UPPER VALVE BODY AND LOWER VALVE BODY




a. Remove the eight bolts from the upper valve body.




b. Remove the five bolts from the lower valve body.




c. Hold the plate to the lower valve body and lift off the lower valve body.

HINT: Be careful that the valves, springs and strainer do not fall out.

1. CHECK INSTALLATION OF KEYS. PINS, CHECK BALLS, STOPPER AND STRAINER




a. Make sure that the keys and strainer on the upper side of the lower valve body are installed correctly.




b. Make sure that the keys, pins, check balls and vibrating stopper on the lower side of the upper valve body and No.2 pressure regulator valve body are installed correctly.







2. POSITION PLATE AND NEW GASKETS ON LOWER VALVE BODY
Position the new No.2 gasket, plate and then the new No.1 gasket on the lower valve body.

HINT: Since the No.1 gasket and No.2 gasket are similar use the illustration to discriminate between them.
