It is upsetting that you experienced this failure.
The failure you describe is not common, actually I have not heard of this part failing. I would thing the unit may have been damaged somehow causing the failure of the part. Did you take the unit to your local Poulan dealer to be looked evaluated? If not I would recommend that you take the pole-saw to your local authorized service center.
