Design Of Measuring System

Information 

Check that there is sufficient floor space between the vehicle and the adjustment device - the gap between the adjustment device and vehicle must be approx. 120 cm.

The vehicle can be reversed onto the axle alignment platform if there is not enough floor space in front of the measuring platform.

The vehicle must be positioned so that the front and rear axles are centered on turnplates/sliding plates.

Information 

The procedure described here is for the wheel alignment system ML 5000 Porsche WE 1272  and the axle alignment system with DSP508XF sensors WE 1328  .

Deviations can occur with other alignment systems.

1. Fit instrument holders onto the wheels on the rear axle.
2. Fit the rear sensors on the rear axle using the spoiler adapter (Beissbarth only, this sets the sensors to a lower position).
3. Align the rear sensors on the rear axle using the spirit level and clamp the instrument holders using the wing screws.

   Information 

   Once the vehicle and adjustment tool are aligned, the vehicle and adjustment tool must no longer be moved.

   • The vehicle is standing on turnplates/sliding plates that are released  on one side , allowing the vehicle to be moved slightly  .
   • If the vehicle is moved while taking measurements on the turnplates, the measurement process must be repeated  .
   • If the adjustment tool is moved following alignment, the measurement process must be repeated  .
4. Attach front sensors to the measuring mirror, align using the spirit level and clamp.
   1. 4.1. Centre the adjustment tool.
   2. 4.2. Set distance of adjustment tool and vehicle in accordance with the specifications provided by the measuring equipment manufacturer.
   3. 4.3. The distance between the left sensor and the vehicle -Bl-  should be identical to the distance between the right sensor and the vehicle -Br-  .
