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)Unplug the unit from the electrical outlet.
2)Remove the panels.
3)Remove the thumbscrews and take off the spout from the evaporator.
4)Loosen the cutter with a wrench and remove it.
5)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. 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.
