STEP 7
Remove the “Air Valve Spool” from
the main “Air-Valve Assembly”.
STEP 8
Using the pick, remove the “Lip
Seal (Air Valve)” from the main
“Air-Valve Assembly”.
STEP 9
Using the pick, remove the
second “Lip Seal (Air Valve)” from
the main “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. Lubrication of the air valve assembly, with a non-
synthetic lubricant, is recommended in order to facilitate re-assembly
into the intermediate. Lubrication is not necessary for pump operation.
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, hole side first. Then install the air-valve end
plug in the bottom of the Air-Valve Assembly.
