12. Lay the pump assembly, pump clip, cotter pin, mix
feed tube, and the agitator in the bottom of the mix
hopper for sanitizing.
13. Slide the large black O-ring and the two smaller black
O-rings into the grooves on the driveshaft.
Thoroughly lubricate the O-rings and shaft. Do not
lubricate the hex end of the shaft.
Figure 6-32
14. Install the hex end of the driveshaft into the drive hub
at the rear wall of the mix hopper.
Figure 6-33
Note: For ease in installing the pump, position the
ball crank of the driveshaft in the three o'clock
position.
Repeat steps 1 through 14 for the other side of the
machine.
Sanitizing
1. Prepare a pail of cleaning/sanitizing solution with an
active chlorine concentrate of 100 ppm–200 ppm
(parts per million).
Important! Use warm water and follow the
manufacturer's specifications.
2. Pour sanitizing solution over all the parts in the
bottom of the mix hopper and allow it to flow into the
freezing cylinder.
Figure 6-34
Note: You have just sanitized the mix hopper and
parts. Therefore, make sure your hands are clean
and sanitized before proceeding with these
instructions.
3. While the solution is flowing into the freezing cylinder,
take particular care to brush-clean the mix-level
sensing probe, mix hopper, mix inlet hole, air/mix
pump, pump clip, mix feed tube, cotter pin, and
agitator.
4. Install the pump assembly at the rear of the mix
hopper. To position the pump on the drive hub, align
the drive hole in the piston with the drive crank of the
driveshaft. Secure the pump in place by slipping the
pump clip over the collar of the pump, making sure
the clip fits into the grooves in the collar. (
