Valve Body Disassembly





1. NOTE THE NUMBERS OF ADJUSTING RINGS

HINT: Count the number of adjusting rings before disassembling 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. REMOVE SOLENOID VALVES
a. Remove the 3 solenoid valves.
b. Remove the 0 - rings from each of the solenoid valves.





4. REMOVE LOWER VALVE BODY COVER
Remove the 10 bolts and the lower valve body cover.





5. REMOVE GASKETS, PLATE AND STRAINER
Remove the 2 gaskets and plate.





6. REMOVE BOLTS FROM UPPER VALVE BODY
Remove the 8 bolts from the upper valve body.





7. REMOVE BOLTS FROM LOWER VALVE BODY
Remove the 9 bolts from the lower valve body.





8. LIFT OFF LOWER VALVE BODY AND PLATE AS SINGLE UNIT
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.

9. REMOVE PLATE AND GASKETS FROM LOWER VALVE BODY

Valve Body Assembly








1. POSITION PLATE AND NEW GASKETS ON LOWER VALVE BODY
Position the new No.2 gasket, the 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 below to discriminate between them.





2. PLACE LOWER VALVE BODY WITH PLATE AND GASKETS ON UPPER VALVE BODY

HINT: Hold the lower valve body, gaskets and plate securely so they do not separate. Align each bolt hole in the valve bodies with the gaskets and plate.





3. INSTALL AND FINGER TIGHTEN BOLTS IN LOWER VALVE BODY TO SECURE UPPER VALVE BODY
Install and finger tighten the 9 bolts.

HINT: Each bolt length (mm) is indicated in the illustration.





4. INSTALL LOWER VALVE BODY COVER
a. Position a new gasket and plate and then another new gasket.





b. Position the lower valve body cover.
c. Install and finger tighten the 10 bolts.

HINT: Each bolt length (mm) is indicated in the illustration.





5. INSTALL AND FINGER TIGHTEN BOLTS IN UPPER VALVE BODY
Install and finger tighten the 8 bolts.

HINT: Each bolt length (mm) is indicated in the illustration.





6. TIGHTEN BOLTS OF UPPER AND LOWER VALVE BODIES
a. Tighten the 19 bolts in the lower valve body.

Torque: 6.4 Nm (65 kgf-cm, 56 inch lbs.)





b. Tighten the 8 bolts in the upper valve body.

Torque: 6.4 Nm (65 kgf-cm, 56 inch lbs.)





7. INSTALL SOLENOID VALVES
a. Install new O-rings on each of the solenoid valves.





b. Install the solenoid valves.

HINT: Each bolt length (mm) is indicated in the illustration.

Torque:
A Bolt 6.4 Nm (65 kgf-cm, 56 inch lbs.)
B Bolt 10 Nm (100 kgf-cm, 7 ft. lbs.)
