CALIBRATION PROCEDURES
(Stockcar Style System TR-212)
If you own a TR-12 Stockcar System you may have already noticed that your TL-40/212
Calibration Bar looks different from the one previously shown in this manual. You may use the
calibration procedure for the TR-30 Easy Check (Caster / Camber) Gauge previously described on
pages 8 and 9 of this manual. The Frame Centering Flags and the TR-44 Level Compensator Bar
calibration can be found on pages 14 and 15 of this manual. To calibrate the TR-36 and 37 Laser
Guns follow the procedure below.
1)
Place the TR-40/212 Calibration Bar on a firm surface with the long end of the bar (the side
that does not have any discs on it) pointing toward a clear area of at least twenty feet (20’).
2)
Hang one of the laser guns on of the fixed discs with the laser head pointing towards the
long end of the Calibration Bar. Level the laser gun and turn it on.
3)
Place the TR-52 Target Kit on a surface at least twenty (20’) feet away from the Laser Gun
on the disc that is level with the laser beam.
4)
Remove the Laser Gun and replace it with the TR-51 Calibration Laser. Turn on the Cal
Laser and point it at the target.
5)
Move the target so that the laser beam is on a number, I.E. the number two (2) on the
target. Once this is done remove the Cal Laser and place it on the opposite disc and point it
at the target, make note of both target readings; for example, the number two (2) from
before and the number ten and one half (10 ½).
6)
Remove the Cal Laser and replace it with both laser guns on the discs, level them, turn
them on, and set the toe dials at zero (0), and adjust both camber adjustment knobs so that
the laser lines are vertical.
7)
If the laser beams match the numbers from the Cal Laser then no further adjustment is
required. The Laser Guns are in calibration.
8) If the laser beams do not agree with the numbers from the Cal Laser then, adjust the toe
dials to the Cal Laser numbers, and verify that the laser beams are parallel by removing the
target from its stand and bringing it up close to the laser boxes. When both the near and far
target readings are the same, reset the toe dial by following the procedure in step 5b on
page 11 of this manual. Once this is done then the laser guns are in calibration.
