MEASURING INFORMATION DIAGRAM DESCRIPTION

Tech Tips


  • There are two types of dimensions in the diagram.

  • In cases in which only one dimension is given, left and right are symmetrical.

  • For symbols, capital letters indicate right side of vehicle, small letters indicate left side of vehicle (seen from rear).


  1. Three-Dimensional Distance

    A004LJBC04
    *a Distance between the centers of the measuring points

    1. Straight-line distance between the centers of two measuring points.

  2. Two-Dimensional Distance

    A004LAPC01
    *a Center-to-center horizontal distance in forward/rearward
    *b Vertical distance to center
    *c Vertical distance to lower surface
    *d Imaginary Datum Line

    1. Horizontal distance in forward/rearward between the centers of two measuring points.

    2. Distance from the Imaginary Datum Line.

  3. Imaginary Datum Line

    A004LCMC01
    *a Under surface of the Rocker Panel
    *b Imaginary Datum Line

    1. The imaginary line used to measure height is a line which connects the points described in the following chart (actual dimensions are listed in the next chapter of this manual).

      Symbol Measuring Points
      A The place that was lowered (1) mm (in.) from the under surface of the rocker panel centered on the front jack up point.
      B The place that was lowered (2) mm (in.) from the under surface of the rocker panel centered between A and C.
      C The place that was lowered (3) mm (in.) from the under surface of the rocker panel centered on the rear jack up point.
  4. Measurement

    A004LASC01
    *a Tracking Gauge
    *b Master Gauge
    *c Pointer
    *d Wrong
    *e Correct

    1. 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.

    2. Use only a tracking gauge that has no looseness in the body, measuring plate, or pointers.

      Tech Tips


      • The height of the left and right pointers must be equal.

      • Always calibrate the tracking gauge before measuring or after adjusting the pointer height.

      • Take care not to drop the tracking gauge or otherwise shock it.

      • Confirm that the pointers are securely in the holes.

    3. When using a tape measure, avoid twists and bends in the tape.
