Evaporator disassembly
Note: The upper and lower bearing assemblies and auger assembly must be replaced as assemblies. The
bottom and top bearing assemblies cannot be field assembled to factory specifications.
1. Disconnect power to icemaker.
2. Shut off water to icemaker.
3. Drain evaporator and float tank.
4. Disconnect plastic tubing from evaporator water inlet.
5. Disconnect ice transport tube from compression nozzle.
6. Remove nut and upper vee band coupling from top of evaporator
(see pg. 19).
7. Lift top bearing assembly straight up with a slight rocking 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.
Evaporator reassembly
1. Clean gearmotor boss, output shaft and shaft well.
2. Degrease OD of gear motor boss.
3. Apply 242 Loctite to OD of boss and install evaporator mounting base.
4. Fill gearmotor shaft well with food grade grease.
5. Install condensate shield and seat against gearmotor boss.
6. Install bearing O ring in groove in evaporator mounting base.
7. Lower bottom bearing assembly into evaporator mounting base.
8. While maintaining a slight downward pressure on bottom bearing
assembly, tighten hex head bolt with a 5/16 wrench.
9. Position evaporator over lower bearing assembly and align grooves
with pins in bearing assembly.
10. Align lower portion of compression nozzle drip guide (if so
equipped) inside evaporator drain pan.
11. Install vee band clamp and nut.
12. Place auger in center of evaporator and rotate to mate with spline.
13. Install ice compression loop, orienting loop as shown on page 19.
14. Install upper bearing and seal assembly, rotating bearing to slip pin
into auger slot.
15. Install upper vee band clamp and nut.
16. If evaporator was replaced, reinstall compression nozzle on new.
Gearmotor replacement
1. Disassemble evaporator as described above.
2. Remove gearmotor drip cap by tapping up on flange at edge of cap.
3. Remove gearmotor cover plate and disconnect the wires.
4. Remove Heyco wire bushing and pull wires out.
5. Remove four screws holding gearmotor mounting plate to base of icemaker and lift gearbox and motor clear
of icemaker.
6. Remove machine screws holding mounting plate to motor.
7. Install new motor in reverse order.
