ERVICE

Assembly and disassembly should be performed by a
service technician who has been factory trained on MBW
equipment.  The unit should be clean and free of debris.
Pressure washing before disassembly is recommended.

• Prior to assembly, wash all parts in a suitable cleaner or

solvent.

• Check moving parts for wear and failure.  Refer to the

Replacement section in this manual for tolerance and
replacement cycles.

• All shafts and housings should be oiled prior to pressing

bearings.  Also, ensure that the bearings are pressed
square and are seated properly.

• All bearings should be replaced when rebuilding any

exciter or gearbox.

• All gaskets and seals should be replaced after any

disassembly.
