SUBJECT:
Modification Kit (MBUSA Special Tool: 900 589 21 21 00)
Consisting of Spacer Ring and 90° Vacuum Connector
(Update to the Distronic Adjustment Device; MBUSA Special Tool: 900 589 07 21 00)
As of Model Year 2006, passenger car models are fitted with a new style Distronic radar module. This means that there are now two variants of the radar sensor (types ARS 200 and 210) which need to be accommodated by the Distronic Adjustment Device; MBUSA Special Tool Number 900 589 07 21 00.
The housing dimension of the new module is different. The distance between the antenna lens surface and the reference surfaces of the radar module Housing is reduced. This is due to the new antenna lens surface now being flat instead of curved. This created the situation where the distance between the Antenna lens surface and the suction membrane of the Distronic Adjustment Device is too large and the necessary suction vacuum can no longer be produced.
To create the necessary suction vacuum, a spacer ring (part number OJV-065) is fitted over the antenna lens surface. This allows the Distronic Adjustment Device to be positioned in the usual way and the necessary suction vacuum can be produced on the antenna lens surface (see figures shown).
Application Hint:
apply a thin layer of anticorrosion grease to the 0-ring seal for an airtight fit.
Vacuum Connection Fitting Modification:
The vacuum connection of the optical adjustment device needs to be modified to accommodate a 90° (right angle) fitting. Perform the modification as follows:
- Remove existing brass, barbed fitting & washer (item 1 on figure shown) from optical adjustment device.
- Assemble the various components from the modification kit in the sequence shown.
washer > spacer fitting > washer> 90° fitting > washer> banjo bolt
maximum torque for the banjo bolt = 4Nm
- Reattach brass, barbed fitting and washer.
maximum torque for the brass, barbed fitting = 4Nm
