Main Control Valve Body: Disassembly
- Remove the pump assembly.
- Remove the separator plate.
- Remove the check balls.
- Remove the filters.
- Remove the relief valves
- Remove the individual valves and springs by removing the retaining clips and bore plugs.
Refer to the Main Control Valve Body Assembly illustration for valve and spring locations. Clean valves, springs and main control valve body.
NOTE:
The valve body separator plate has a bonded gasket.
NOTE:
Be sure to note the location of the check balls.
NOTE:
Be sure to note the location of the filters.
NOTE:
Be sure to note the location of the relief valves.
CAUTION:
Most valves are aluminum and cannot be removed using a magnet.
Remove the valves by tapping valve body on the palm of the hand to slide the valves out of the bores. It may be necessary to remove the valves and springs using a pick. If it is necessary to use a pick, use extreme caution to prevent damaging the valves or valve bores. If necessary, disassemble parts of the main control valve body in small groups.
Take special care when handling the main control components, since they are the most precise and delicate parts of the transaxle.
Neatly arrange the parts as they are removed to avoid mixing similar pieces.
