RUN OUT PROCEDURE
Once the wheel clamps have been mounted, run out should either be performed on the two front
wheels or all four, depending what type alignment is preferred. For a Two-wheel Centerline
alignment, adjust run out on both front wheels. For a Thrust Angle alignment, or Four-wheel total
alignment, adjust run out on all four wheels.
Note:
For Run-Out using Hub Adapters Please refer to the General Alignment Procedure
Section #4a.
The following should be completed before run out adjustments are made:
x
Front and rear wheel clamps must be installed
x
The vehicle must be raised, so the wheels can rotate freely.
Run Out Procedure
:
1)
Place the TR-30 on the disc extending from the wheel clamp.
2)
Level the TR-30, using the SAI scale on the top of the post. Make sure the TR-30 can move
easily, so that it stays relatively level when the wheel clamp is rotated.
3)
Rotate the wheel clamp until the installation knob is at a 12:00 position. Set the caster
bubble to zero on the caster scale; this is done with the caster adjustment knob, which is
located on body of the TR-30.
4)
Rotate the wheel clamp ½ turn; the installation knob should be at a 6:00 position.
5)
Level the TR-30 and read the number on the caster scale.
6)
Adjust the bubble to the point halfway between 0 and the current reading using the RED
knob on the TR-28. (When making this adjustment, it is important not to move the bubble
with the caster adjustment knob.)
7)
Rotate the wheel ¼ turn to the right, so the installation knob is at a 9:00 position.
8)
Level the TR-30, and set the caster bubble to zero with caster adjustment knob.
9)
Rotate the wheel ½ turn, until the installation knob is at a 3:00 position.
10)
Level the TR-30, read the number on the caster scale.
11)
Adjust the caster bubble to the point halfway between 0 and the current reading, using the
two BLACK knobs on the wheel clamp.
