Solenoid Valve Disassembly and Assembly

The numerical sequence shown on the illustration is
intended as a guide to dismantling.
NOTE: It is not normally recommended to remove the
spool 12, Figure 7-72 from the valve body. None of
the component parts of the CETOPS valve
assembly can be renewed individually. The extent
of permissible servicing is cleaning and the
consequential renewal of O-ring seals. If damage
to any component or distortion of the spool is
evident the complete valve assembly must be
renewed.
Great care should be taken when disassembling and
assembling the valve to avoid the following:
• Contamination
• Damage to spools
• Damage to seal grooves
Any of the above may result in possible problems with the
operation of the valve.
For assembly the sequence should be reversed.
7-48
For clarity, only one solenoid has been numbered in the
dismantling sequence.
