Evaporator reassembly

  1.  Clean gearmotor boss, output shaft and shaft well.

  2.  Install drain pan and evaporator mounting base. 

  3.  Fill gear motor shaft well with food grade grease 

(Fig. 27.1).

  4.  Install condensate shield and seat against gear 

motor boss.

  5.  Install bearing O ring in groove in evaporator 

mounting base.

  6.  Lower bottom bearing assembly into evaporator 

mounting base.

  7.  While maintaining a slight downward pressure on 

bottom bearing assembly, tighten hex head bolt with 
a 5/16" wrench.

  8.  Position evaporator over lower bearing assembly 

and align grooves with pins in bearing assembly.

  9.  Install vee band clamp and nut to 70 in/lb.

 10.  Place auger in center of evaporator and rotate to 

mate with drive pin.

  11.  Install ice compression loop, orienting loop as 

shown in Fig. 28.

 12.  Install upper bearing and seal assembly, rotating 

bearing to slip pin into auger slot. 

 13.  Install upper vee band clamp and nut to 70 in/lb.

 14.  If evaporator was replaced, reinstall compression 

nozzle on new evaporator.

Evaporator disassembly
Note: 

The upper bearing, lower bearing and auger 

assemblies must be replaced as assemblies. The bottom 
and top bearing assemblies cannot be fi eld assembled to 
factory specifi cations (Fig. 26)..

  1.  Disconnect power to icemaker.

  2.  Shut off water to icemaker.

  3.  Drain evaporator and fl oat tank.  

  4.  Disconnect plastic tubing from evaporator water 

inlet. 

  5.  Disconnect compression nozzle tubing and reservoir 

overfl ow tubing from secured clip.

  6.  Remove nut and upper vee band coupling from top 

of evaporator 

  7.  Lift top bearing assembly straight up with a slight 

rotating motion and remove.

  8.  Remove ice compression loop located at top 

of auger.

  9.  Lift auger straight up and out of evaporator.

 10.  Remove nut and lower vee band coupling from 

bottom of evaporator.

  11.  Lift evaporator to clear bottom bearing assembly.

 12.  Loosen hex head bolt in side of mounting base with 

5/16" wrench and lift lower bearing assembly.

 13.  Remove condensate shield.

 14.  Remove four Allen head machine screws holding 

mounting base to gearbox.

 15.  If replacing evaporator, remove compression nozzle 

from evaporator port.
