Three-Dimensional Measurements

Three-dimensional measurements are provided in the absences of dimension information from your equipment supplier. Universal 3-dimensional measuring equipment is required to use these numbers. You may need to adjust the height dimensions to match the datum height of your equipment. Only the width dimensions can be used to measure point-to-point. All holes, slots and fasteners are measured from the center.

2WD shown; 4WD dimensions are the same, graphics similar. All dimensions are measured in millimeters, from a zero line, center line, and a common datum. All dimensions are symmetrical, unless otherwise specified.

Point to Point Measurements

Point-to-point measurements are for reference only. Use these measurements for diagnosis for validating. Point-to-point measurements do not afford the accuracy that 3-dimensional measuring systems have. Point-to-point measurements are duplicated with tram bar pointers set at equal lengths. All holes, slots, and fasteners are measured to the center.
