Air/Mix Pump Assembly - Taylor 8756 Operator's Manual

Air/Mix Pump Assembly

This Model 8756 uses a single-stage pump. The
purpose of the pump is to transfer specific amounts
of air and mix to the freezing cylinder.
Step 1
Inspect the rubber and plastic pump parts. These
parts must be in 100% good condition for the pump
and entire machine to operate properly. They cannot
properly serve their intended function if nicks, cuts,
or holes in the material are present.
Inspect the plastic pumps parts for cracks, wear,
and de-lamination of plastic. Replace any defective
parts immediately and discard the old.
Step 2
Assemble the piston by sliding the check band and
the o-ring into the grooves on the piston. Do not
lubricate the check band or o-ring.

Note: A concave shaped check band indicates an
incorrect assembly. Turn the check band inside out
to correctly expose the flat surface.

Step 3
Slide the small o-ring into the groove in the air
orifice. DO NOT lubricate this o-ring.
Step 4
Check the small hole in the air orifice to insure that it
is not clogged. Place the air orifice into the top of the
piston.
Step 5
Lightly lubricate the inside of the pump body, top
and bottom.
