The purpose of this SAE Recommended Practice is to establish test procedures and minimum performance standards for kingpins and their supporting structure manufactured to SAE specifications. The dimensions shown in SAE J700 will permit the establishment of standard clearances in the installed condition which, in turn, will permit fifth wheel manufacturers to design their products to establish interchangeability with any kingpin made and installed to the SAE specification.
Rationale:
The Truck and Bus Coupling & Interchangeability Committee which owned this report has become inactivated and the technical expertise for the subject report within the Truck and Bus Council is not available at this time. This standard has been transferred to the Total Vehicle Steering Committee to stabilize the standard.
