When the series was introduced, some vehicles were built with no colored mark on the cable of the belt tensioner. These must be tested as follows:
-
Remove protective rubber cap on end of tube and measure distance "X". To do this, insert a round implement or screwdriver of approx. 10 mm
diameter and measure the depth.
Model
Distance "X"
107
140 mm ± 5 mm
123
140 mm ± 5 mm
126
170 mm ± 5 mm
If the measured distance is shorter than the distance given above, the belt tensioner has been triggered and must be renewed.
Type 2
As of 01/86, there is an observation window in the housing of the belt tensioner, through which the cable is visible. This means that it is no longer
necessary to remove the belt tensioner for the test. Belt tensioners where no cable is visible have been triggered and must be renewed.
Type 3
As of 08/87 belt tensioners are supplied by two manufacturers.
