Figure 13
Use tool shipped with pump to remove
Uni-Flo™ end caps (one on each side)
from center assembly.
STEP 14.

Turn tool counterclockwise to loosen. Use
caution not to force it as the small pins on
the removal tool can shear off. If one side
is not coming loose, turn over and try the
second side.
STEP 15.
Figure 15
After removing the Uni-Flo™ end caps,
remove pilot pin and o-ring. Inspect for
damage. If air valve internals are damaged or
worn, a complete Uni-Flo™ air valve assem-
bly must be purchased as a replacement.
STEP 16.
Figure 16
Place tool such that pins are sticking
upward and push the valve out the bottom
end with your thumbs (you may need to
use a rubber mallet to gently tap the tool to
initiate movement.) Do not hit the valve
directly with a tool.
