Alignment Checking

Alignment Checking

Use a measuring tram gauge as an accurate method of determining the alignment of the underbody. The tram gauge set required to perform the recommended measuring checks must include a vertical pointer capable of reaching 457 mm (18 in).

The following 2 types of measurement may be made using a tram gauge:

-Direct point to point measurements

-Measurements calculated on a horizontal plane (datum line) parallel to the underbody

Dimensions that are measured to gauge holes are measured to the center of the holes and flush to the adjacent metal surface unless otherwise specified. It is recommended that the diagonal dimensions be cross body checked on both sides in order to verify the dimensional accuracy of the vehicle underbody. Set vertical pointers equally as needed per your application.
