Upper Bearing Wear Check; Removal And Replacement Of Cutter - Hoshizaki MODULAR CUBELET SERENITY SERIES FS-1022MLH-C Service Manual

1. Upper Bearing Wear Check

To ensure that the bearing inside the extruding head does not exceed the wear tolerance
of .02", follow the instructions below.
1) Remove the front panel. Move the power switch to the "OFF" position, then unplug the
unit from the electrical outlet.
2) Remove the top and side panels.
3) Remove the strap connecting the spout to the chute assembly, then remove the spout.
4) Remove the bolt from the auger and lift off the cutter and washer.
5) Replace the bolt in the auger. Grasp the
bolt at the top of the auger and move the
auger towards you and then try to insert a
.02" round stock or pin gauge in between
the back side of the auger shaft and the
bearing surface. Check several locations
around the auger shaft. If the gauge goes
between the shaft and the bearing at
any point or if the bearing is scratched
or cracked, both the top bearing in the
extruding head and the lower bearing in
the lower housing should be replaced.
Instructions for removing the extruding
head and lower housing are located later in
this procedure.
Note: Replacing the bearing requires a bearing press adaptor. If one is not available,
replace the whole extruding head and lower housing.

8) Replace the top and side panels in their correct positions.
