Extruding Head
7) 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, both the top bearing in the extruding
head and the lower bearing in the housing
should be replaced. Instructions for
removing the 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.
8) Remove the three socket head cap screws and lift off the extruding head.
Auger
9) Lift out the auger. If the area in contact with the bearing is worn or the blade is
scratched, replace the auger.
