Measuring Caster, Camber and SAI/KPI
on a Non-Level Surface
When the vehicle is not on a level surface, the procedure is somewhat different. The
TLT-30 Easy Check Angle Gauge is used in conjunction with the TLT-44 Level
Compensator Bar to correct the readings. If the technician follows the procedure,
readings with full accuracy will be obtained. Even though the measurements are accurate,
the ground should be reasonably near level to assure that the vehicle suspension is not
affected.
When the calibration procedure is complete, measurement of camber is done as follows:
1.
Mount TLT-28 Wheel Clamps on front wheels (both sides).
2.
Raise wheel and adjust run-out using the standard procedure (both sides).
3.
Lower wheel onto turn table and remove locking pin (both sides).
To Measure Camber on a Non-Level Surface
1.
Place TLT-44 Level Compensator Bar (that has been assembled to match the
tread width and is calibrated) in front of wheels as shown in Figure 20.
2.
Beginning on the left side, hang TL-30 Easy Check Angle Gauge on the mounting
disk on the left side of the Level Compensator Bar and adjust camber zero knob to
zero the camber bubble.
3.
Measure camber on the same left of the vehicle.
4.
Repeat steps 2 and 3 on the right side.
NOTE: Remember to zero the camber gauge each time before you measure camber.
To Measure the Side to Side Tilt for SAI/KPI
SAI/KPI readings are affected by the side to side tilt of the vehicle. The following
procedure compensates for the tilt to give full accuracy SAI/KPI readings. You can make
the SAI/KPI readings first, or after this procedure.
1.
Place the bar in front of the wheels as shown in Figure 13 with the red side on
the right side.
2.
Hang the gauge on the red side and zero the camber bubble using the camber zero
adjust knob (refer to Figure 3)
