Upper Bearing Wear Check - Hoshizaki C-80BAJ 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) Move the control switch to the "OFF" position, then unplug the appliance from the
electrical outlet.
2) Remove all ice from the storage bin.
3) Remove the top panel. See Fig. 4.
4) Remove the spout and packing.
5) Remove the cutter.
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. 6. 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 entire extruding head and housing.
7) Replace the removed parts and panel in the reverse order of which they were removed.
8) Plug the appliance into the electrical outlet, then move the control switch to the "ICE"
position to start the automatic icemaking process.
