Solenoid Valve (1- 4)
Dismantling the Solenoid Valve (1-4)
Note: The sleeve 11, the spools 23, 23 and the body 15 are
clearance packed separately, the position of the the solenoid
20 is decided by the identifying colour of the connection
section. This must be checked during dismantling.
1 Remove the hex socket bolt 32.
2 Remove the solenoid coil 20. Care must be taken not to
lose the push rod.
3 Remove the o-ring 32.
4 Remove the spools 23, 24. Remove the spool by
inserting a scraper bar onto the small hole in the spool

as a sub-assembly including the plain washer 34, the
spring 6 and the stopper 26.
Cleaning / Inspection
1 Clean the dismantled parts with a coating of clean oil.
2 Dry with compressed air. Place each part on a clean
sheet of paper or vinyl for inspection.
3 Verify that all sliding parts move easily.
4 Check that there is no foreign matter in any passages or
grooves.
Assembling the Solenoid Valve (1-4)
1 Install the spools 23, 24 to the sleeve 11.
2 Install the sleeve to the body.
3 Install the ‘O’ ring 39 to the solenoid coil 20. Install the
‘O’ ring to the solenoid coil to avoid damaging the ‘O’
rings.
4 Install the solenoid coil 20 to the body 15.
Note: Confirm that the push pin is inside the solenoid coil.
Care must be taken to avoid dropping the push pin
during assembly.
5 Refit the hex. socket bolts 32.
Torque tighten to 3.92 Nm (2.89 lbf ft).

6 Check that there is no foreign matter in any passages or
grooves.
Assembling the Optional Solenoid Valve
