Types of body measurements
The reference dimension information below will assist technicians with diagnostics and body repairs. Size information is provided in two forms. Dimensions are given in the X, Y, Z coordinate system and as the actual distance between the characteristic points of the body.
The X,Y,Z axes form the coordinate system used by Land Rover for inspection measurements of body parts. The geometry of the whole body is considered in a system of parallel lines forming a grid, as shown in the illustrations below.
The X axis is the horizontal axis starting at the front of the vehicle. It determines the distance 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 about the longitudinal axis of symmetry.
The Z axis is directed vertically upwards, perpendicular to the plane of the bottom of the body. All Z coordinates are measured from the origin of the Z axis.
The point-to-point dimension is the distance between two characteristic points on the body. Such points are holes or intersection points. If the characteristic point is a hole, then 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 car is±1.0 mm (0,040). This applies to mounting holes, all mounting holes and cutouts in body parts.
The tolerance on the shape of the body panels and on the borders of the panels is±0.5 mm.
