I was removing the pulley from a power steering pump on a 1990 Dodge D250 pickup. This requires the use of a special pulley remover tool. I have one and began the removal process.

My puller was working just fine, then quit pulling all of a sudden.

This is one of the threaded parts of the pulley remover.

There are supposed to be a bunch of threads in there. Where did they all go ?

Oh, there they are. After many years of use, the threads finally gave up.

Looks like I'll be needing a new puller.
