Dismantling and Assembly
Notes:
1 All parts are precision made and require the utmost
care when being handled.
2 During dismantling, do not use excessive force to
separate components which could cause scratches or
burrs on bearing surfaces. Failure to observe this
instruction will cause oil leaks leading to poor
performance.
3 Label all parts during dismantling, to ensure correct
assembly.
4 Storing the valve when dismantled could cause rusting
of parts. Ensure they are suitably protected by anti-rust
treatment.
5 During assembly, ensure all parts are clean and free
from burrs and scratches. Remove minor damage by
lapping.
6 Renew all ‘O’-rings, seals and back-up rings. Take care
to install seals the correct way around.
7 During assembly apply hydraulic oil to ‘O’-rings and
seals.
8 Ensure all screws and bolts are tightened to the torque
settings given.
