The scope of this SAE Recommended Practice, trailer axle alignment, is to identify the dimensional limits of, and a method to, establish a perpendicular relationship between the king pin centerline and the axle centerline at its midpoint. Various types of equipment are commercially available which can be used for this measurement which provides varying degrees of accuracy, but none can be endorsed by SAE. The most fundamental methods of measurement will be described here, but other equipment is available if a greater degree of accuracy is desired.
This SAE Recommended Practice sets forth recommended back of cab to rear axle (CA) dimensional data. It applies to 4- and 6-wheel motor trucks but not necessarily to truck-tractors.
This SAE Recommended Practice applies to upper coupler kingpins for commercial trailers and semitrailers conforming to the dimensional requirements of SAE J700 when new and originally installed. The dimensions of SAE J700 are the frame of reference for this document.
