Control Valve Body

A: PRECAUTION








The control valve is composed of parts which are accurately machined to a high degree and should be handled carefully during disassembly and assembly. As these parts are similar in shape, they should be arranged in neat order on a table after disassembly so that they can be easily installed to their original positions. Spring loaded parts should be also handled carefully, as springs may jump out of place when the parts are disassembled or removed. Extreme care should be taken so as not to drop valves on the floor. Before assembling, the parts and valves should be dipped in a container filled with the ATF. Make sure that the valves are clean and free from any foreign material before assembly. Torque specifications should also be observed.

B: DISASSEMBLY





1. Remove oil strainer from lower control valve body.





2. Remove the duty solenoid S. solenoids and sensor from the lower valve body.





3. Remove the upper-lower valve body tightening bolts.
4. Separate the control valve body.

CAUTION:
- Do not lose the ten (10) steel balls contained in the upper valve body and middle valve body.
- Do not lose strainers contained in the lower valve body.

NOTE: During ordinary servicing, clean the control valve bodies in this condition, without further disassembly. In the event of a seized clutch or other problem, disassemble the control valve bodies further, and clean the component parts.





5. Remove upper separator plate from middle valve body.
6. Remove valve springs from upper valve body.





7. Using air compressor, remove accumulator piston from upper valve body.

C: INSPECTION
Make sure that each component is free of harmful gouges, cuts, or dust.

D: ASSEMBLY





1. Install accumulator pistons, valve springs and steel balls to upper valve body.

CAUTION: Insert steel balls in their proper positions.





2. Install support plate and upper separate plate to middle valve body.

CAUTION: Align the hole in support plate with the hole in separate plate.

Tightening torque: 8 ± 1 Nm (0.8 ± 0.1 kg-m, 5.8 ± 0.7 ft. lbs.)





3. Install steel balls to middle valve body.

CAUTION: Insert steel balls in their proper positions.





4. Install three filters to lower valve body.

CAUTION: Pay attention to the location of filters.





5. Install lower separate plate to lower valve body





6. Temporarily assemble valve body.

CAUTION: Be careful not to drop the middle valve body and upper body interior steel ball, or the lower body filter.





7. Tighten bolts.
