Upper Bearing Wear Check - Hoshizaki F-330BAH 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 appliance from the electrical outlet.
2) Remove top panel and top insulation panel.
3) Remove the thumbscrews attaching
spout (B) to the bin, then remove spout (B).
See Fig. 3.
4) Remove the thumbscrews attaching spout
(A) and safety bracket (A) (if applicable)
to the evaporator assembly, then
remove spout (A) and safety bracket (A)
(if applicable). See Fig. 3.
5) Loosen the cutter with a wrench and remove it.
6) Grasp 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. See Fig. 5. 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 housing should
be replaced. Instructions for removing the extruding head and 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 housing.
7) Replace the cutter in its correct position.
8) Replace the spouts in their correct positions. If applicable, make sure the safety switch
components are in position. See Fig. 3.
9) Plug the appliance into the electrical outlet, then move the power switch to the "ON"
position.
10) Replace the panels in their correct positions.
