Specifications

Problem:
The belt drive fails due to the defective idler pulley. Part of the
plastic running surface has been worn through.
Cause:
The idler seizes due to inadmissible contact with the cover.
The timing belt destroys the idler after a short period because
of the belt sliding over it.
Solution:
Always make sure that the cover of the timing belt drive is
positioned correctly and check for any potential distortion due
to heat input. Long-term operation can be ensured only when
the pulleys can rotate freely.
