Measurement options
- Comparative measurements can also be made on the outside of the body. Depending on the damage, comparative and diagonal measurements can be made using a compass, telescopic rod, tape measure or ruler.
NOTE: When checking for dimensional stability on both sides of the vehicle, the same reference points (e.g. drill holes, edges, stamping relief, etc.) should be selected.
- All important dimensions are listed in the section "Body Repair: Checking Dimensions". For additional information, refer to the chapter: Body and Frame (501-26 Body Repairs - Vehicle Specific Information and Tolerance Checks, Description and Function).
- Measurements using a frame.
- To accurately check the dimensions of the body, a frame stand is required. Measuring systems are divided into categories according to their operating principle:
- Mechanical measurements.
- Optical measurements.
Fast and accurate measurement results can be obtained using computerized measuring systems.
To check the dimensions of length, width and height, at least three undamaged points of the body are required.
In some cases this may require access to such points. All of these measuring systems can be used to perform body measurements, provided the appropriate equipment is available.
Planning a renovation
Before starting repairs, the following decisions must be made:
- Does the car need to be mounted on a straightening stand or can it be straightened in another way?
- Is it necessary to carry out control measurements of the body?
- Is it necessary to remove units such as the engine?
NOTE: It is preferable to repair body components rather than replace them, as this will avoid damage to the entire body frame.
- What body parts need to be replaced?
- Which body parts can be repaired?
Receiving spare parts
Availability of spare parts often determines how easily a body repair can be performed. The following procedure is recommended:
- Get all vehicle data including type, vehicle identification number, trim code, engine identification letters, primary registration details, etc.
- Identify all metal components that need to be replaced.
- Identify all fasteners that need to be replaced, including small items such as rivets, clips, etc.
