Types of body measurements
The following information on control dimensions helps technical personnel in diagnostics and body repair. The information on dimensions is given in two forms. Dimensions are given in the X, Y, Z coordinate system and as the actual distance between characteristic points of the body.
The X,Y,Z axes form the coordinate system used by Land Rover for the control measurements of body parts. The geometry of the entire body is considered in a system of parallel lines forming a grid, as shown in the illustrations below.
The X-axis is a horizontal axis starting at the front of the car. It defines distances along the length of the body.
The Y axis is a horizontal axis perpendicular to the X axis, with the origin in the vertical longitudinal plane of symmetry of the body. All Y coordinates start from this plane. As a rule, all transverse dimensions of the body are symmetrical relative to the longitudinal axis of symmetry.
The Z axis is directed vertically upward, perpendicular to the plane of the body bottom. All Z coordinates are counted from the beginning of the Z axis.
The point-to-point dimension is the distance between two characteristic points of the body. Such points are holes or intersection points. If the characteristic point is a hole, the distance is always measured from the center of the hole.
The measured dimensions are shown in millimeters. Dimensions in inches are given in brackets.
The tolerance for the main dimensions of the vehicle is ±1.0 mm (0.040). This applies to the mounting holes, all fastening holes and cutouts in the body parts.
The tolerance for the shape of body panels and panel boundaries is ±0.5 mm.
