I read pictures far better than I read words. Thank you for always posting pictures.

Richard, they could be punched out easily with the right machine.  I used some scrap metal, happened to be a piece of a ride height valve.  I doubt there is a large market but perhaps the boating industry would make it worthwhile.

Thanks Jack, I'm following your lead on show & tell.

I get concerned when the pump seal doesn't allow the armature to turn.  I wiggle it back & forth a little at a time to break it loose, always worried about causing damage to the seal.

I’ve got a pump that hums for maybe 30 seconds to a minute and then stops humming. I ran the coach out of water and after filing got a little burst of water and then nothing.

Thinking maybe some kind of air lock? Called Headhunter and they recommended trying to turn that shaft, but my pump is mounted about 2 inches off the wall so every combination of right angle screw drivers I can muster do not fit.

Any suggestions before I dig deeper?

How do I get a screwdriver in there with the pump being mounted about two inches from the wall?

Use a key or coin to remove the plug.  Find a piece of metal 3" long around 3/8" wide and 1/16" thick.  That should work

I can remove the plug, but there is no room the way mine is mounted to get a 3" piece in there.  I might have to play around with piecing together several different combinations of extensions.  I'm thinking if I have a flat head bit that is maybe two inches long it will make it past what is some kind of sleeve and then it can attach a 1/4 inch drive, etc.  Tough to see what I'm working with where it's mounted so close to the wall of the bay.

The link is just for the pictures, easier to see than describe. Any auto parts store or Lowes will have them.

Mine is about 3" clearance.  I think if you had that piece of metal previously discussed you would probably find you could get it in the hole and make it work.  If not, go with a slightly narrower piece of metal.  It has to go in the hole quite a ways to engage the armature.  You do not want to lose a segment of screwdriver in that hole.

Played around with a few screwdriver extensions and was able to make sure pump spun freely.  Found the culprit.  I don't think the capacitor is supposed to look like this.  Headhunter shipped out a new one and all is well with the world.
