Checking with the bar (control gauge) – consisting in comparing the measurements done in symmetric points. CHECKING OF THE LONGITUDINAL GIRDERS POSITION The checking of the longitudinal girders position consist in comparing the measurements done on symmetric points. The checking of B – B’ , H – H’ points is affecting the mechanical part of the half-front axles and of the rear axle. Certainly, the distances between the points must be equal, as The checking of A,F,F’ , A’ points is affecting the centering of removable parts of the body. The distances between the points must be equals, as follows: AF = A’F’. COLLISION DIAGNOSIS |
