Problem

This program is to provide additional 3176 Product Support at truck engine overhaul. This program may only be applied at the time of overhaul and must be used in conjunction with a customer purchased 0R8216 Engine Kit. Some parts that do not typically require replacement at first overhaul may be needed in addition to the overhaul kit (reference the "Parts Needed" section of this letter). If additional parts covered in this program do require replacement, use this program to limit customer participation.
