Dismantling
Notes:
1. All parts are manufactured with a high degree of
precision and require the utmost care when handling. Do
not let parts knock against each other and take extra
precautions when handling parts to prevent them being
dropped.
2. During dismantling, do not hit parts with excessive force
if they are stuck and do not damage parts by twisting
them or making burrs on bearing surfaces. Failure to
follow these instructions will cause oil leaks leading to
poor performance.
3. Label all parts during dismantling to ensure correct
assembly.
4. Storing of the control valve in a dismantled or partly
dismantled state could cause rusting of parts due to
moisture or dirt. If the dismantling procedure must be
interrupted, be sure to provide anti-rust treatment and
keep the parts free from dirt and corrosion.
5. During assembly ensure that all parts are free from dirt
and foreign matter and make sure that all parts are free
from burrs and scratches. Remove minor burrs and
scratches using an oil stone.
6. Use new 'O'-rings and backup rings.
7. During assembly, apply grease to 'O'-rings.
8. Tighten all bolts to the quoted tightening torque.
1. Remove knob from pilot valve.
Note: Take care when removing the pilot valve because of
the wiring loom.
2. Remove the boots (cover) from the pilot valve.
3. Remove the piping. (Attach tags to the connecting ends
of the piping to facilitate reassembly).
