and clean the cylinder wall with a Scotchbrite pad & cleaner.
The extruding head surface may also have heavy scale
and can be cleaned with Scotchbrite & cleaner as well.
AUGER BEARINGS:
Bearing Type: Sleeve/Alignment,
Bearing Material: Poly/Carbon
The bearings are pressed into the top extruding head and
lower brass housing. A repress program is available
through the local Hoshizaki Distributor for undamaged extruding
heads and housings. The bearings should always
be replaced as a set. Return the extruding head and housing
to your distributor for an exchange set or to be returned
for repressing.
BEARING INSPECTIONS:
Annual bearing inspections are recommended. More frequent
inspections may be necessary in poor water quality
areas. The steps for bearing inspections are as follows:
(1 ) Gain access to the ice chute head by removing the top
panel and spout connectors as necessary.
(2) Remove the thumbnuts which hold the ice chute head in
place and lift it up and off of the evaporator (take care to
place the O-ring in a safe location until you replace the
head.)
(3) Remove the stainless steel bolt holding the cutter or
breaker in place and lift off to access the extruding head
and auger shaft.
(4) Replace the bolt into the auger shaft and use it to push
the auger back and forth from left to right to check for
excessive movement.
(5) Pull the auger towards you and try to insert a .02” round
stock or pin gauge in between the back side of the auger
shaft and bearing surface. Check several locations around
the auger shaft. If the gauge will go in between the shaft
and bearing, it is time to install new bearings. Both top and
bottom bearings should be replaced if the top bearing is
worn. If there is no excessive movement in the auger shaft
and the gauge does not fit, the bearings are okay. Replace
the cutter, O-ring, ice chute head and connectors.
