Power steering shaft thread size

RobsFreeland · Jan 23, 2021

used pulley press from local parts store to press on pulley. Problem is I think the threads are bunged up in the shaft. It was a 3/8 bolt with a 9/16 head grade 8. It goes in part way then stops. Used it to push on pulley almost the entire way. Need another inch to finish it off. But bolt keeps coming off. Went to hardware store for 10 mil bolt thinking it’s metric instead of standard. Want to go in but stops and cannot get a bite.
I’m going to rethread the shaft but I can’t find threa$ size of shaft.

Does anybody know the tap size to rethread the shaft?

It is going to be whatever the thread is on the bolt supplied with the press. If I remember it is 3/8" course thread, but I could be wrong and is fine thread. Match a tap with the bolt supplied with the press. But if I was you, I would get another pump. The bolt supplied with the press should be the standard one to use and if will not thread in far enough, that means the shaft threads were likely damaged when remanufactured.

Yep 3/8 coarse thread. Got a bunch of crap out of shaft. No pun intended. Pulley is on.

Glad to hear it.

In the future, if you can’t find a tap, you can take a dremel and cut some grooves along the length of a bolt that fits. This will clean out the threads pretty well.
