Maintenance: Component Inspection
Auger. The auger is made of stainless steel. It has a polished surface that may be very shinny or dull. Allow the auger to dry, if mineral scale is found on the auger’s surface, clean off the auger with ice machine cleaner and a scrubbing pad.
Remove the water seal and clean off the shoulder of the auger.
Bearings: The top bearing should spin freely with no rough spots. If it feels rough when spun by hand, replace it. There should be minimal rust or dirt. If in doubt, replace the bearing.
The bottom bearing must be removed from the evaporator when replacing the water seal.
Remove the three bolts holding the evaporator to the gearmotor adapter and lift the evaporator up slightly. Tap the water seal and bottom bearing out from the top down. Check the bottom bearing the same way as the top.
Replace the water seal and install a new bearing set if needed.
To replace the water seal:
1.Remove old rotating half from the auger. Clean the mounting area.
2.Place a bead of food grade sealant (such as Scotsman part number
3.Wash the new seal in water. While wet, slip it onto the bottom of the auger, rubber side toward the auger. Push up until seated against the sealant. Do not allow any sealant to come into contact with the face of the seal.
4.Wash the stationary half the water seal with
water. Slip it up into the bottom of the evaporator until the bottom of the seal is inside the evaporator about 1/4".
5.Push the bottom bearing against the water seal until the bottom bearing is inside the evaporator about 1/16".
6.Replace the evaporator on the adapter, and
7.Attach the auger to the top bearing and breaker.
8.Return the auger to the evaporator and slide it down until the splines touch the coupling.
9.Rotate the auger until the coupling splines align with the auger.
10.Push the auger down, and rotate the breaker until the screw hole lines up with the pilot hole in the evaporator.
11.When the auger is completely seated, reinstall the breaker screws.
12.Replace spout and rubber top.
13.Switch on the water supply.
14.Observe operation. The unit should make minimal noise while producing ice. Catch first 2 minutes of ice and discard it.
15.Replace all panels.
Coupling
Use the grease zerk on the side of the coupling to add grease once per year.
That concludes normal maintenance. If the fan motor has an oil plug, it may be oiled after 10 years of operation.
