With O-ring pick, gently remove the O-ring from the opposite side of the center hole cut on
the spool. Gently remove the pilot spool from sleeve and inspect for nicks, gouges or other
signs of wear. Replace pilot sleeve assembly or outer sleeve O-rings if necessary. During
reassembly never insert the pilot spool into the sleeve with the center cut side first, this
end incorporates the urethane O-ring and will be damaged as it slides over the ports cut in
the sleeve.
NOTE: Seals should not be removed from pilot spool. Seals are not sold
separately.
Check center section Glyd™ rings for signs
of wear. If necessary, remove Glyd™ rings
with O-ring pick and replace.
