Pump Assembly
Step 1 Assemble the piston. Slide the red o-ring into the groove of the piston. DO NOT
lubricate the o-ring.
Step 2 Apply a thin layer of lubricant to the inside of the pump cylinder at the retaining pin
hole end.
Step 3 Insert the piston into the retaining pin hole end of the pump cylinder.
Step 4 Assemble the valve cap. Slide the o-ring into the groove of the valve cap. DO NOT
lubricate the o-ring.
Step 5 Slide the pump valve gasket into the holes on the cap. DO NOT lubricate the gasket.
Step 6 Insert the valve body cap into the hole in the mix inlet adapter.
Step 7 Insert the mix inlet assembly into the pump cylinder. The adapter must be positioned
into the notch located at the end of the pump cylinder.
Step 8 Secure the pump parts in position by sliding the retaining pin through the cross holes
located at one end of the pump cylinder. Note: The head of the retaining pin should be
located at the top of the pump when installed.
Step 9 Install one red o-ring on each end of the mix feed tube, and thoroughly lubricate.
Step 10 Slide the check ring into the groove of the feed tube.
Step 11 Lay the pump assembly, pump clip, cotter pin, and mix feed tube assembly in the
bottom of the mix hopper for sanitizing.
Step 12 Slide the large black o-ring and the two smaller black o-rings into the grooves on the
drive shaft. Thoroughly lubricate the o-rings and shaft. DO NOT lubricate the hex end
of the shaft.
Step 13 Install the hex end of the drive shaft into the drive hub at the rear wall of the mix
hopper. Note: For ease in installing the pump, position the ball crank of the drive shaft
in the 3 o'clock position.
Step 14 Repeat these steps for the other side of the machine.
