Disassembly :
1- Remove the plastic nuts holding the coils.
2- Remove the O-rings and the coils.
3- Remove the poletubes using adequate tooling
(Ref. 990005), (Torque to unscrew : 13 to 33
N.m).
4- Remove the spring guides and drive the spool
out of the sleeve.
Inspection :
1- Clean all parts with an appropriate solvent and
dry with compressed air.
2- Check the spool surfaces are not scratched.
3- Check the axial and radial holes at each end
of the spool are not blocked.
NOTE
If the spool is scratched or if the holes are
blocked, the spool AND the sleeve must be
replaced.
If the spool and the sleeve have to be replaced, drive
the sleeve out of the manifold using an appropriate
mandrel in the direction indicated in the drawing below
:
Assembly :
Never interchange spools and sleeves. All
components must be clean before assembly.
1- Check for burrs that could damage O-rings
during the installation of the sleeve.
2- Install the O-rings on the sleeve.
NOTE
Ensure the seals are not stretched and the
grooves damaged during assembly.
3- Lubricate the seals before sleeve installation
(MILLCOT K320 or equivalent).
4- Insert the sleeve in the manifold using an
appropriate mandrel in the direction indicated
in the drawing below :
5- Lubricate the spool with clean hydraulic oil.
Slide the spool into the sleeve as indicated
below. Ensure the spool slides freely inside the
sleeve.
6- Install the spring guide on face B side as
indicated in the drawing below. Install the spring
in the poletube. Install the poletube on the
manifold using Loctite® 245. Torque the
poletube to 10 - 12 N.m using adequate tooling
(Ref. 990005).
NOTE
The thread on the poletube must be free from
oil or grease before the glue is applied.
