off the compressed air, bleed pressure
from the pump, and disconnect the air
supply line from the pump.
STEP #1:
See COMPOSITE
REPAIR PARTS DRAWING.
Using a 3/8" wrench or socket,
remove the four hex flanged capscrews
(item 12). Remove the air valve assembly
from the pump.
STEP #2:
Disassembly of the air
valve.
To access the internal air valve
components first remove the two end
cap retainers (item 1-G) by inserting
a small flat screwdriver into the two
slotted grooves on the valve body and
gently lifting the retainers out.
Next remove the two end caps (item
1-E) by grasping the pull tab with finfer
and thumb or pliers and tugging. Inspect
the two o-rings (items 1-C and 1-F) on
each end cap for wear or cuts. Replace
the o-rings if necessary.
Remove the spool (part of item 1-
B) from the sleeve. Be careful not to
scratch or damage the outer diameter
of the spool. Wipe spool with a soft
clean cloth and inspect for scratches
or abrasive wear.
Inspect the inner diameter of the
sleeve (part of item 1-B) for dirt,
scratches, or other contaminants.
Remove the sleeve if needed and
replace with a new sleeve and spool
set (item 1-B).
Note:
The sleeve and
spool set is match-ground to a specified
clerance. Sleeves and spools cannot be
interchanged.
STEP #3:
Reassembly of the air
distribution valve.
Install one end cap with o-rings
(items 1-E, 1-C, and 1-F) into one end of
the air valve body (item 1-A). Insert one
end cap retainer (item 1-G) into the two
smaller holes, align with groove in the
end cap, and push until the closed end
of the retainer is below the flat surface
of the valve body.
Remove the new sleeve and spool
set (item 1-B) from the plastic bag.
Carefully remove the spool from the
sleeve. Install the six o-rings (item 1-
C) into the six grooves on the sleeve.
Apply a light coating of grease to the
o-rings before installing the sleeve into
the valve body. Align the slots in the
sleeve with the slots in the valve body.
Insert the spool into the sleeve. Be
careful not to scratch or damage the
spool during installation. Push the spool
in until the pin touches the end cap on
the opposite end.
Install the remaining end cap with
o-rings and retainer.
Fasten the air valve assembly (item
1) and gasket (item 23) to the pump,
using the four hex flanged capscrews
(item 12).
Connect the compressed air line to
the pump. The pump is now ready for
operation.
IMPORTANT: Remove the safety
clip. The pump will not function properly
until it is removed. The pump is now
ready for operation.
Read these instructions
completely, before in-
stallation and start-up.
It is the responsibility of
