Completely disassembled and cleaned the unit. Inspected for broken or worn parts.
Determined one rotor blade had broken and that one bearing had some rust and was running rough.
Ordered the required parts. When the parts arrived, lubricated the entire unit and reassembled with the new components.
Biggest issue I encountered was the left hand thread locking collar use on the body of CP854 grinder. Once that was loosened the repair was routine
