## Discrepancy

THE DRIVE GEAR ON THE BENDIX DRIVE SHUTTERED.  THIS ALSO CURVED SEVER DAMAGE TO THE TEETH ON THE RING GEAR RENDERING THE RING GEAR UNSEVERICEABLE.  WE HAD 2 PREVIOUS PROBLEMS WITH THE BENDIX ON NEW STARTERS THESE.  RELATED TO THE DRIVE NOT ENGAUGING OR DISENGAGING PROPERLY.  THIS IS A MUCH MORE SEVERE PROBLEM AND IS PROBABLY RELATED TO A MATERIAL DEFECT IN THE PART.
