AIR DISTRIBUTION VALVE WITH
STROKE INDICATOR OPTION
SERVICING
To service the air valve first shut off the
compressed air supply, bleed the pressure
from the pump, and disconnect the air
supply line from the pump.
Step #1: See COMPOSITE REPAIR PARTS
DRAWING.
Using a 5/16" Allen wrench, remove the
four hex socket capscrews (item 12) and
four flat washers (item 39). Remove the air
valve assembly from the pump.
Remove and inspect gasket (item 19)
for cracks or damage. Replace gasket if
needed.
Step #2: Disassembly of the air valve.
To access the internal air valve
components first remove the two retaining
rings (item 1-H) from each end of the air
valve assembly using clip ring pliers.
Next remove the two end caps (item
1-E). Inspect the o-ring (items 1-G) for cuts
or wear. Replace the o-rings if necessary.
Remove the spool (part of item 1-A)
from the sleeve. Be careful not to scratch
or damage the outer diameter of the spool.
Wipe spool with a soft cloth and inspect for
scratches or wear.
Inspect the inner diameter of the sleeve
(part of item 1-A) for dirt, scratches, or other
contaminants. Remove the sleeve if needed
and replace with a new sleeve and spool
set (item 1-A).
Step #3: Reassembly of the air valve.
Install one end cap (item 1-E) with
o-ring (item 1-G) into one end of the air valve
body (item 1-B). Install one retaining ring
(item 1-H), into the groove on the same end.
Remove the new sleeve and spool set
(item 1-A) from the plastic bag. Carefully
remove the spool from the sleeve. Install the
six o-rings (item 1-G) 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 (item 1-B). 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 it touches
the bumper on the opposite end.
Install the remaining end cap with
o-rings and retaining ring.
Fasten the air valve assembly
(item 1) and gasket (item 19) to the pump.
Connect the compressed air line to the
pump. Remove the safety clip. The pump is
now ready for operation.
