  1. Product Recall • What? • An incorrect combination of flat washer and serrated nut was used in the engine compartment to secure the starter power cable. • When? • August, 2010 • Why? • The flat washer prevents the serrated nut from locking against the attaching bracket. Over time, the serrated nut may back off allowing the starter cable to fall and contact the fan hub while in operation. This could result in a direct short and potential vehicle fire http://www-odi.nhtsa.dot.gov/acms/docservlet/Artemis/Public/Recalls/2010/RCLMTY-082010-1234.pdf ETM591 Tie Duan

  2. Management Issues • This problem was initially reported by a Blue Bird customer whose starter cable fell off the mount onto the fan hub. • The report was filed in mid August, immediate actions were taken to investigate and formulate a solution. • Engineering solution is to replace all serrated nuts used in engine and chassis cable mounting with lock nuts with nylon insert. • The recall involves notifying the owners and repair free of charge • The recall process began on September 24, 2010.
