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
