Symbol | Measuring Points |
A | The place that was lowered <1> mm from the under surface of the rocker panel centered on the front jack up point. |
B | The place that was lowered <2> mm from the under surface of the rocker panel centered between A and C. |
C | The place that was lowered <3> mm from the under surface of the rocker panel centered on the rear jack up point. |
Measurement |
![]() |
Basically, all measurements are to be done with a tracking gauge. For portions where it is not possible to use a tracking gauge, a tape measure should be used.
Use only a tracking gauge that has no looseness in the body, measuring plate, or pointers.
When using a tape measure, avoid twists and bends in the tape.
