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 F-330BAJ(-C): 11.1 ft-lb/15 N·m. Tighten 2 times. Allow at least 5 sec. in
between each tightening.
Component Notes
Compressor • Install a new drier, start capacitor, and start relay.
Upper and Lower
Bearings
• Inspect the upper bearing for wear. See "IV.B.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.
Ifworn, cracked, or scratched, the mechanical seal should also be replaced.
Gear Motor • Install a new gear motor capacitor.
