Scotsman MDT3F - Manual (Page 16)

Auger and Bearing Inspection
While in most areas regular in-place cleaning with
Scotsman scale remover will be adequate to keep
the interior of the evaporator free of excessive
mineral build up, some water conditions may
require more intense methods. In addition, the
auger bearings require physical inspection to
determine that they are not wearing. This physical
inspection is recommended twice per year for the
top bearing and once per year for the auger and
both bearings.
Whenever the auger is removed, replacement of
the water seal is recommended.
If a bearing requires replacement, the other
bearing must also be replaced.
Note: The bearing design changed in April
2010. These directions are for removal of the
auger and apply to all versions
1. Unplug or disconnect electrical power.
2. Shut off the water supply.
3. Remove top panel.
4. Remove right side panel.
5. Drain the evaporator and reservoir.
6. Remove cap from top of evaporator.
7. Remove 2 permagum plugs from the side of the
evaporator.
8. Remove 2 screws (screwheads were covered by
the permagum).
9. Pull up on:
a) Design from 2001 to 2007: The pull ring to
remove the auger.
b) Design from 2007 on: Obtain a 1 1/2" pipe
thread tee. Install the Tee, it will screw onto the
breaker. Pull up on the Tee or insert a bar thru the
Tee and pull up on it to remove the auger and top
bearing retainer.
If it is difficult to pull:
·
Design from 2001 to 2007: Remove the breaker
cover by taking the snap ring out.
·
All versions: Unscrew the auger bolt.
·
All versions: Use threaded rod or a slide
hammer puller and screw into the auger, slide
the weight quickly up against the stop to remove
the auger.
If the auger still will not move, bearing replacement
is mandatory. See Bearing Removal and
Replacement.
