Caster Angle To measure the caster angle, use a Bear or Duby Gauge as shown in Plate 3, Figs. 8. 11. Be sure to have all four wheels the same distance off the floor. Fkxx-must be level. On early 341-A and 303 cars, the spring seats are not machined at the same angle as on later cars. To give these cars the standard caster angle specified in the table, use tapered shims (Fig. 9) between the springs and the axle. Place the thick edges of the shims toward the rear. 2. Straightening Bent Parts Because of their location the parts of the front axle are more subject to damage by accident, than any other part cf the chassis. Front axk service, therefore, involves the inspection of parts for alignment and possible straightening. Heat-treated parts should not be straightened if they are sprung out of alignment more than 5°. To straighten such parts while cold is likely to result in strains and sometimes in cracks not visible to the naked eye. Straightening with heat destroys the effect of previous heat treatment and may result either in overheating, making the steel soft and weak, or in underheating, which will make it brittle and easily broken. Parts which are not heat-treated may be straightened cold if not sprung out of alignment more than 10". Welding of parts subjected to severe strain should never be permitted. A welded part is never as strong as the original, unbroken metal and the heat required for the welding process changes the structure of the metal around the weld, making it coarse and weak.
