AUGER INSPECTION / BEARING
REPLACEMENT
A visual inspection of the auger bearing shaft surface is
also recommended annually in poor water areas. The steps
for this inspection is as follows:
Note: Clean the evaporator prior to removing the auger.
This will loosen scale around the extruding head
and allow for easier removal.
(1) Follow steps 1 through 5 of the bearing inspection procedure
above.
(2) Remove the (metric) Allen head cap screws that secure
the extruding head in place.
(3) Thoroughly drain the water supply system.
4) Turn the cutter up-side down, replace the bolt and use
the cutter to lift the auger out of the evaporator. If heavy
scale is present the auger may be difficult to remove. In this
case, you will find it helpful to clean the evaporator system
following the instructions located on the Inside front panel,
before you attempt to remove the auger.
(5) With the auger removed, remove the cutter and slide
the extruding head from the top of the auger. Visually inspect
the bearing surface at the top and bottom of the
auger. Also inspect the auger flight and mechanical seal for
any damage. The extruding head contains the top bearing,
the bottom bearing is pressed into the brass housing at the
bottom of the evaporator. To remove the housing:
(6) Remove the Allen screws that secure the evaporator to
the housing.
(7) Loosen the belly band screw and lift the evaporator up
