If a vehicle is involved in an accident that may result in a bent or sprung frame, inspect the vehicle for the following conditions:

There are 2 different methods for determining vehicle measurements:

A tram gage is a quick reference for determining vehicle damage. The tram gage set requires a vertical pointer that is capable of reaching 914 mm (36 in).

Measure the engine compartment components from point to point using the equally set vertical pointers.

Use the vertical pointers in order to make other measurements on the horizontal plane or the datum line, parallel to the underbody. Ensure that the pointers are set as specified for each point.

When measuring dimensions to the gage holes, measure to the center of the holes flush to the adjacent surface metal. Cross-check the diagonal dimensions in order to verify the dimensional accuracy of the vehicle underbody.

If you are measuring the structural repair, ensure that the repair equipment is capable of the following multiple points simultaneously:

Measure 2/3 of the vehicle body in order to obtain accurate comparisons to the vehicle structure.

Universal measuring systems combine the use of equipment and the techniques in order to make underbody and upperbody 3-dimensional measurements.

The universal system provides accurate measurements of the following items simultaneously:
