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

    A0120QTE04

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

      *1 Distance between the centers of the measuring points

  2. Two-Dimensional Distance

    A0120RRE01

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

    2. Distance from the Imaginary Datum Line.

      *1 Center-to-center horizontal distance in forward/rearward
      *2 Vertical distance to center
      *3 Vertical distance to lower surface
      *4 Imaginary Datum Line

  3. Imaginary Datum Line

    A0120QXE01

    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).

      *1 Under surface of the Rocker Panel
      *2 Imaginary Datum Line
      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.

  4. Measurement

    A0120NYE01

    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.

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

      *2 Master Gauge
      *3 Pointer

    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.
