Wrap the upper pump rod (2) with protective material or use
wood/plastic blocks to grip it in a vise. Use a wrench to remove
the air motor assembly at the hex adaptor (1) pump rod (2)
joint.
Note:
If the upper pump rod needs replacement, do so
before the new air motor is installed (refer to Replacing the
Upper Pump Rod). Apply thread adhesive to the air motor
before installation.
Upper Spring and Flat Seal Replacement:
Unscrew cap (17) from air piston tube (22). Remove screw
(21), spring retainer (20) and spring (19) and lift out upper
gasket (18). Reassemble in reverse order.
Replace the lower gasket (18) while the tube is off the body
(25). Be sure the new gasket is flat against the body before
assembling the tube
Replacing Parts in the Footvalve:
Grip pump tube (35)
and footvalve (37) with separate strap wrenches. Unscrew
the footvalve, drive out retainer pin (38) with a 1/8” diameter
punch, remove lower ball (14) and/or o-ring (36) as necessary.
When reassembling the pump tube to the lower pump body, be
sure to check the upper o-ring (34) for damage and replace as
necessary. Apply grease to the footvalve threads and o-rings
(34,36) and reassemble.
Replacing the Upper Pump Rod:
Grip only the upper rod in
a vise. Use a 1/8” spanner wrench to remove the floating joint
adapter (5) and air motor assembly (1) from the upper rod.
Wrap the replacement upper rod in protective material before
placing in the vise. Apply thread adhesive to both internal
threads of the pump rod and reassemble the connecting
parts.
Replacing the Lower Pump Rod:
Grip only the lower rod
in a vise. Use a 1/8” spanner wrench to remove the floating
joint adapter (5) from the upper rod (2). Wrap the upper rod
and air motor assembly and set aside.
Use an adjustable wrench to remove lock nut (3). Slide off
washer (4) and adapter (5). Remove connecting rod (6) with
a pipe wrench. Wrap replacement lower rod in protective
material before placing in the vise. Apply thread adhesive to
the connecting rod (6) and reassemble with the short thread
length into the rod. Replace the washer (4), adapter (5) and
nut (3). Tighten nut completely then back off 1/4-tum to allow
free movement of adapter. Apply thread adhesive to the
adapter and reassemble.
Pump Reassembly:
Apply grease to the lower pump rod end,
wiper seal (30) and o-ring (24). Slide the lower spring (23) over
the upper pump rod and then slide the entire upper rod/lower
rod/air motor assembly through the pump. Some resistance
will be encountered as the lower rod passes through the wiper
seal (30). Reinstall the upper ball (14) and piston (15). Insert
a 1/4” diameter rod through the pump rod and tighten the
fluid piston with a wrench. File off any burrs or raised areas
created during the repair process.
Grease o-rings (16,34) and pump tube (35) threads before
reassembling to the body. Tighten with a strap wrench.
Grease the air motor assembly and inside the tube (22),
reassemble and tighten with a strap wrench.
