Valve Body
CAUTION: The valve body assembly is a precision
unit with select fit components that are hydraulically
matched and balanced during manufacture. Service re
pairs to the valve are uncommon with the possible ex
ception of the spool valve damper O-ring. Do not
disassemble the valve body unless absolutely necessary
as improper disassembly could result in damage. If the
spool valve damper O-ring requires replacement, re
move the valve, replace the O-ring, and reinstall the
valve immediately. If either the spool valve or valve
body require replacement, replace the entire valve body
as an assembly only. Do not attempt to interchange
parts. If valve body disassembly is absolutely necessary,
proceed as outlined in the following steps.
Disassembly
(1) Remove and discard stub shaft cap O-ring (fig.
