power steering pump pulley
I bought a used power steering pump from a salvage yard and the pulley came with the pump but wasn't on the shaft. Inside the shaft is threaded but I can't tell what size bolt to use and was wondering if anyone knew what the thread size is?

If your asking this question cause you need to get the pulley off, I would suggest you go to an autoparts store and rent a power steering pulley removal/installation tool. Its usually free and will save you a lot of trouble.

Then you need an installation tool. If you try it with just a bolt and washers, the threads will pull out of the pump shaft.
The tool has a bearing that is pushed by a fine thread pusher thing. |

You need to use the installation tool. Don't use a bolt in the shaft. It puts too much stress on the threads, you will ruin the new pump.

They don't have a bolt. That's probably why you can't find one.
The installer tool is a threaded rod that screws into those threads; then a nut screws down against the pulley, with a bearing to take up the turning force. The corner parts stores "rent" the tool for free. Then when you're through, you take the threaded rod tool out and return it to the store. The pulley will be flush with the end of the pump shaft, and is a REAL TIGHT press fit, such that it doesn't need a bolt at all. But he was struggling with all that over 11 years ago; I hope he got his figured out sometime since then and it isn't still kicking his butt. ;) Meanwhile, if your pulley is on all the way, then your job is done. |
The threads are only used to install the press fit pulley. No bolt is needed after that.
