Air Valve Assembly
To assemble the air valve, reverse the order of disassembly. During
assembly, ensure that the open side of the lip-seals are both facing each other inward.
Install the shuttle plate with the smooth/shiny side toward the shuttle car. Lubrication
of the air valve assembly, with a non-synthetic lubricant, is recommended. Magna-Lube
or Magna-Plate are recommended for assembly lubrication (see detailed parts list for
ordering information).
Note that if the lip-seals are installed incorrectly, they will be unable to rotate. Insert the
spool, larger chamber side first, the spool’s longer piston with the boss is to be on the
plug side, ensure O-Ring is installed, and then the air-valve end plug into position.
STEP 7
Remove the “Air Valve Spool” from the
main “Air-Valve Assembly”. Note: The
longer piston with the boss is on the
plug side, insert larger chamfer first.
STEP 8
Using the pick, remove the “Lip Seal
(Air Valve)” from the main “Air-Valve As-
sembly”.
STEP 9
Using the pick, remove the second “Lip
Seal (Air Valve)” from the main “Air-
Valve Assembly”.
