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.
