DEFECT #1 - TRAILER HITCHES:FIFTH WHEEL ASSEMBLY
Posted on: 1979-10-12
Description
Certain structural welds attaching the king pin to the king pin mounting structure may have been omitted or applied with poor welding techniques. This could allow the king pin to loosen from its supporting structure.
Consequence
Corrective Action
Dealer will inspect and rework the king pin mounting structure to ensure welding is secure, without charge to owner.
Notes
Vehicle description: semi-trailers, tandem axle.system: structure; king pin.consequences of defect: continued operation could lead to separation of thesemi-trailer from the towing vehicle under certain off road conditions orsevere braking applications. This could result in a vehicle accident.
DEFECT #2 - SERVICE BRAKES, AIR:SUPPLY:HOSES, LINES/PIPING, AND FITTINGS
Posted on: 1979-10-12
Description
The rear emergency glad hand was improperly connected directly to the rear air tank rather than to the emergency port of the task valve. Consequently, if the air supply to the lead trailer became disconnected, the emergency brakes would be applied but the rear trailers would not. A heavy brake application would cause the rear trailer to push the lead trailer forward, increasing the vehicle braking distance, and creating the potential for a jack knife.
Consequence
Corrective Action
Dealer will inspect and, if necessary, modify the connections in the braking system, without charge to owner.
Notes
Vehicle description: semi-trailers.system: air brakes; emergency glad hand.consequences of defect: increased braking distance may lead to a vehicleaccident and personal injury.
DEFECT #3 - SERVICE BRAKES, AIR:SUPPLY:RESERVOIR
Posted on: 1979-10-12
Description
The involved vehicles fail to conform to federal motor vehicle safety standard no. 121, air brake systems, in that a 3/8-inch diameter red synflex tubing was incorrectly installed. The tubing may have been installed so that the two air reservoirs are directly connected and both reservoirs would be affected if service brake air pressure is lost. Reduced air pressure in both reservoirs will not allow the parking brakes to be completey released.
Consequence
Corrective Action
Dealer will reroute the tubing to comply with the safety standard, at no charge to owner.
Notes
Vehicle description: trailers.system: parking brakes; air reservoir tubing.consequences of defect: since the trailer would be rendered immobile, thepossibility of a collision with other vehicles exists.
DEFECT #4 - SERVICE BRAKES, AIR:ANTILOCK:INTERCONNECTING ASSEMBLY(WIRING)
Posted on: 1979-10-12
Description
The involved vehicles do not conform to federal motor vehicle safety standard no. 121, air brake systems. Incorrect wiring of the positive and negative power leads for the brake system renders the anti-skid feature inoperable.
Consequence
Corrective Action
Dealer will rewire the braking system to comply with the safety standard, without charge.
Notes
Vehicle description: heavy trucks.system: service brakes; brake control wiring.consequences of defect: with the anti-skid feature inoperable, brake lock-upcould occur under certain circumstances, possibly causing loss of vehiclecontrol and an accident.
