B. Component Service Information
NOTICE
• When replacing a component listed below, see the notes to help ensure proper
operation.
• When replacing evaporator assembly and water circuit components, make sure
there are no water leaks after the repair is complete.
• Seal bolts must be replaced once removed because seal material is one-time use
only. If new seal bolts do not have preapplied threadlocker, apply Loctite243 or
equivalent threadlocker to seal bolt threads. Tighten to the torque values listed
below.
Torque for DCM models: 11.1 ft-lb/15 N·m
Component Notes
Compressor Install a new drier, start capacitor, and start relay.
Fan Motor Install a new capacitor.
Thermostatic
Expansion Valve
• Attach the thermostatic expansion valve bulb to the suction line in the same
location as the previous bulb.
• The bulb should be between the 10 and 2 o'clock positions on the tube.
• Secure the bulb with the clamp and holder, then insulate it.
Upper and Lower
Bearings
• Inspect the upper bearing for wear. See "IV.C.1. Upper Bearing Wear Check."
Replace if necessary.
• When replacing the upper bearing it is advised to also change the lower bearing at
the same time.
Evaporator • Install a new drier.
• Inspect the mechanical seal and O-ring prior to installing the new evaporator.
If worn, cracked, or scratched, the mechanical seal should also be replaced.
Gear Motor Install a new gear motor capacitor.
