• The spool and body are selectively fitted, so if
one is found to be damaged, replace the valve as-
sembly.
• Apply a thin coating of hydraulic oil to sliding
surfaces and a thin coating of grease to seals when
assembling them.
• Replace seals with new parts each time disassem-
bly is done.
The following describes the disassembly procedure.
For assembly, follow the disassembly procedure in
the reverse order.
