Specifications
Problem:
The tensioning lever chafes against the tensioning pulley.
This can result in serious damage to the engine.
Cause:
Due to improper positioning during installation, the tensioning
lever comes into contact with the running surface after the
parts have been in operation only briely. By way of illustration,
the side facing the engine is shown here (normally hidden).
Solution:
Carefully check the position of the tensioning lever on the
check stud. Only the lever contact surface shown here must
be allowed to make contact with the catch. This ensures the
running surface’s freedom of movement.
