Operating Procedures
The Model 428 freezer is designed to produce shake or
slush product at the desired thickness. This machine has
a 7 qt. (6.6 L) freezing cylinder.
We begin our instructions at the point when we enter the
store in the morning and find the parts disassembled and
laid out to air-dry from the previous night's

brush-cleaning.
These opening procedures will show you how to
assemble these parts into the freezer, sanitize them, and
prime the freezer with
fresh mix in preparation to serve
your first portion.
If you are disassembling the machine for the first time or
need information to get to this point in our instructions,
turn to Disassembly on page 6-11 and start there.
Assembly
Note: When lubricating parts, use an approved food
grade lubricant (example: Taylor Lube).
1. Slide the O-ring into the groove on the driveshaft.
Lubricate the O-ring and shaft portion that comes in
contact with the bearing.
Do not lubricate the square
end of the driveshaft.
Figure 6-1
Note: To ensure that the mix does not leak out of the
back of the freezing cylinder, the middle section of the
boot seal should be convex, or extend out from the seal.
If the middle section of the boot seal is concave, or
extending into the middle of the seal, invert the seal.
Figure 6-2
2. Lubricate the boot seal groove and slide the boot
seal over the shaft and groove until it snaps into
place. Fill the inside portion of the seal with 1/4 in.
(6.35 mm) more lubricant. Install the driveshaft.

3. Insert the driveshaft into the rear shell bearing and
engage the square end firmly into the female socket
of the drive unit. Make sure the driveshaft fits into the
drive coupling without binding.
