- Component:
- Structure:frame and members
- Affected:
- 308
- Notes:
- Freightliner campaign no fl-0030.trucks.possibility that the crossmembersmay develop fatigue cracks in the tow hitch bracing rods.if this occurs itcould allow the tow hitch crossmembers to separate from the bracing rods and/orthe chassis frame members.(correct by inspecting and modifying thecrossmember bracing system).
- Campaign:
- 74V067000 on 10/11/1979
- Component:
- Structure:frame and members
- Affected:
- 60
- Notes:
- Tractor.built june 1,1973 to april 25, 1974.possibility that thecrossmember in the tow hitch attachment area may develop fatigue cracks.thiscondition, if it exists, can ultimately allow the tow hitch to separate fromthe crossmember.(correct by inspecting and modifying all crossmembers byadding a double plate behind tow hitch attaching bolts).
- Campaign:
- 75V119000 on 10/11/1979
