Step 4
Remove air valve end cap to expose air
valve spool by simply lifting up on end cap
once air valve bolts are removed.
Step 5
Remove air valve spool from air valve body
by threading one air valve bolt into the end
of the spool and gently sliding the spool out
of the air valve body. Inspect seals for signs
of wear and replace entire assembly if
necessary. Use caution when handling air
valve spool to prevent damaging seals.
NOTE: Seals should not be removed
from assembly. Seals are not sold
separately.
Step 6
Remove pilot spool sleeve retaining snap ring
on both sides of center section with snap
ring pliers.
Step 7
Remove pilot spool sleeve from
center section.
Step 8
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.
