Dismantling and Assembly
Float Spool
The numerical sequence shown on the illustration is
intended as a guide to dismantling.
For assembly the sequence should be reversed.
Great care should be taken when dismantling and
assembling a 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.
Dismantling
When removing 'O' Rings and seals, use an appropriatly
rounded tool that WILL NOT cause any damage to the seal
grooves.
Discard ALL 'O' Rings. DO NOT use worn or damaged
items.
Remove retainer 7 and spacer 8. Using a suitable tool on
ball 12, compress spring 13 and allow detent balls 11 to roll
into their holes in the detent pin 14. Carefully remove the
spool cap 10 and collect detent balls 11.
Inspection
Inspect the valve components for scratches, nicks or any
other type of damage, replace with new if required.
Assembly
Renew wiper 5 and 'O' rings 6, 20, 21 and 24.
Apply grease liberally to detent pin 14 to hold detent balls 11
in position during assembly and to provide lubrication.
