Ball Stopper Problem

[desertfox384]

Ok so i was oiling seals and noticed my ball stopper was shredded at the tip, so i replaced with a new one and once i bolted everything down i noticed the bolt was getting caught on the tip of the new stopper. After a few hits by the bolt the tip shredded off again. Is this normal? If not what is causing this?

do you have yout bolt in the right way? one side of the bolt should be channeled out for the detent so it doesnt shread it.
