To assemble the mix pumps, first locate the pump
gears (#38&#38A) and pump body (#39). Lightly
lubricate the top, bottom, and inside bore of the
gears. Install the gear into the appropriate gear
well. Install and lubricate oring (#1178) into the
pump body (#39).

NOTE: DO NOT lubricate the gear teeth since this
is removed when the pump starts running.

Install the mix pump drive shaft seal into the rear of
the mix pump body. 

Lightly 

lubricate the inside of

the shaft seal then install the drive shaft into the
pump seal engaging it into the drive gear.

Install the pump body assembly into the rear hub
inside of each mix storage tank. Slide the drive
shaft into the rear hub and rotate the pump until the
hook stud engages the pin on the rear hub. At this
point, you must ensure that the drive shaft is
engaged into the rear drive coupling by turning the
drive gear until it completely engages.

Assemble the plastic suction tube (#271) by
installing the oring (#1126) into the groove and
lightly lubricate. Next lightly lubricate the base
(flat part) of the relief valve (#245) and install into
the well of the mix pump cover (#202).
Install the spring (#206) onto the relief valve in the
pump well. Install the suction tube with lubricated
oring into the pump cover well engaging the spring
into the suction tube recess. To lock the suction
tube onto the pump cover, rotate, the tube until the
adjustment lever is pointed away from the pump
cover (6 o’clock position).

You are now ready to install the pump cover with
suction tube onto the pump body assembly, which
is installed on the rear pump hub in the mix storage
tank. To install the cover, first ensure that the oring
(#1178) is installed into the pump body (#39).
Next, affix the pump cover onto the pump body
using the two metal retaining knobs (#8).

The freezer is now completely assembled and must
be  sanitized prior to adding fresh mix and
operating.
