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) Turn off the power supply.
2) Remove the 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.
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
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.
6) Remove the bolt. Replace the cutter and then the cutter bolt.
7) Replace the spout.
8) Replace the panels in their correct positions.
9) Turn on the power supply.
