Note
♦
Intermediate values for reduced damping performance cannot
be read out.
♦
A prognosis on service life is not permitted.
♦
Measured values that occur with the involvement of the sus‐
pension travel end stops are incorrect.
The following values apply only to the test stands named above.
If the specified values are exceeded, the shock absorber action
has weakened enough that a replacement is recommended.
Example:
Threshold = 70
♦ a = greater than 70: insufficient damping effect.
♦ a = less than 70: sufficient damping effect.
Shock absorber combination installed in vehicle is indicated by
corresponding PR number on vehicle data plate.
Clarification of weight Production Relevant numbers (PR number)
refer to ⇒ “5.3 PR Number Explanations”, page 248 .
Threshold “a” in mm
Note
♦
If the readout value is greater than the limit value “a” (table
value): insufficient damping effect ⇒ replace shock absorber.
♦
If the readout value is less than the limit value “a” (table value):
sufficient damping effect ⇒ shock absorber does not need to
be replaced.
