CALIBRATION PROCEDURES
(Independent Suspension System TR-12)
Using the TR-40 Calibration Bar, you are able to calibrate the TR-12 wheel alignment system,
which consist of the TR-30 EZ Check Gauge, TR-36 Left Laser Gun, TR-37 Right Laser Gun, TR-
38 right Combi, and TR-39 left Combi. For maximum accuracy, it is important to check and, if
necessary, recalibrate the alignment system periodically

First:
Calibrating the camber of the TR-30, TR-38, and TR-39.
Note
: There is a pivot plate at the end of the TR-40, which has a mounting disc attached to the end,
a master bubble vial affixed to the plate, and an adjustment knob. The pivot plate is designed to
eliminate any pitch in the bar or non-level surface. It is used to calibrate the camber vials on the
TR-30 and both Combi gauges.
1)
Place the TR-30 EZ Check gauge on the mounting disc of the pivot plate.
2)
Use adjustment knob, just above the pivot plate, center the master bubble the.
(This must be done with the gauge on the disk.)
3)
Check the camber scale on the gauge. If the bubble of the camber scale is at zero, the gauge
is calibrated. However, if the camber bubble is not at the zero position, the gauge must be
adjusted, until the camber bubble is zeroed.
