Impeller came loose

[chrisinslc]

Just pulled my impeller off to switch to another that had been repitched and when I pulled the pump and shaft out the impeller was loose on the shaft. I thought the reverse thread would keep that from happening. How tight do you go when putting it back on? Waiting to hear from someone before I reinstall. I used the cheater bar and leaned in to it pretty good. Is that all you folks do?

Never heard of or experienced that before... It's typically a struggle to "break" it loose. Some will come off more easily than other.
Not necessarily a concern, there is really nowhere for it to go, unless something else is missing.

I don’t believe that I tightened mine beyond wrench tight when I installed the new ones.

You missed out on all the fun of breaking it loose on the removal!

This time I took the cheater bar and really put it on tight. Hopefully this was just a fluke.

Nothing worse than preparing with a long bar, brace yourself, and give a huge yank and almost fall because it wasn't tight at all. You Look around in embarrassment to make sure no one saw you almost hurt yourself.

Since it is reverse threaded it can't unwind itself, the engine keeps it tight.....I wouldn't put much pressure on it at all....you are lucky yours came off without a fight!
