Over-torquing may damage the ball guide and prevent
normal operation of the pump.
8. Apply a light coat of household oil to the piston and insert
it, shaft first, into the lower end of the fluid section until it
seats. Tap the bottom of the piston gently with a rubber

3. Rotate the fluid section to align the hole in the piston shaft
with the holes in the yoke.
4. Insert the pin through the yoke
and piston.
5. Snap the retaining clip around
the pin and yoke.
6. Screw the fluid section into the
pump housing as far as it will
go, then unscrew it slightly so
that the fluid hose fitting will
align with the fluid hose.
7. Firmly tighten the lock nut at the
top of the fluid section assembly
against the pump housing using
an adjustable wrench.
