Tram Gauge Method
| • | Use a tram gauge as a quick reference in order to determine vehicle damage. Use a tram gauge set with a vertical pointer capable of reaching 914 mm (36 in). |
| • | Make the engine compartment component measurements from point to point with the vertical pointers equally set. |
| • | Make the other measurements on the horizontal plane, or the datum line, parallel to the underbody with the vertical pointers set as specified for each point. |
| • | Measure dimensions that are measured to the gauge holes to the center of the holes and flush to the adjacent surface metal unless otherwise specified. Cross-check the diagonal dimensions in order to verify the dimensional accuracy of the vehicle underbody. |
3-Dimensional Method
| • | Measure following multiple points when measuring structural repair with repair equipment: |
| • | The length |
| • | The height |
| • | The width |
| • | Measure 2/3 of the vehicle body in order to obtain accurate comparisons to the vehicle structure. |
| • | Univeral measuring systems combine the equipment and the techniques used to make the underbody 3-dimensional measurements. The universal system provides accurate measurements of the following points: |
| • | The length |
| • | The width |
| • | The height |
