The most basic types of equipment for wheel alignment are the turning radius gauge, the caster-camber gauge, and the tram gauge. These are
Figure 8-52.- Toe-out on turns. In larger shore facilities these basic types of equipment are normally replaced with a large alignment rack. The alignment rack consists of ramps, turning radius gauges. and specialized equipment for measuring alignment angles. Turning Radius Gauges The portable type turning radius gauges are the most common in the Naval Construction Force (NCF). However, they are also mounted on alignment racks as integral units. The front wheels of the vehicle are centered on the turning radius gauges. With the front wheels centered, the locking pins are pulled out which allows the gauge and tire to turn together. The pointer on the gauge will indicate how many degrees the wheels have been turned. The procedures for checking toe-out on turns using turning radius gauges are as follows: Center the front tiresofthe vehicle on the turning radius gauges and remove the locking pins. Turn one of the front wheels until the gauge reads 20 degrees.
