Now that I have installed a new pump at my well, I am trying to restore the old Goulds Jet Pump, 1 HP. It appeared to be "frozen" so I took it apart and it had must rust inside it. is there a way to remove the rust from both the armature (stator??) and rotor surfaces? Sand paper? What grit? It...

Wow, too much- I unscrewed the old tank from the old pump, tank is still good, almost new. Added a little pressure to 20 lbs (stated on sticker), screwed it onto the top of the pump thread, turned on the power, and pump runs, then stops, and stays off! Tested pump by turning on the hose faucet...

Thanks, Tom. I peeked around a bit more before I started messing with the speings like you said, and i decided to take apart the 2 nipples on the to/from the narrow pressure black tube that feeds the PS. They both were clogged! Geez, no wonder. I ran a fine steel wire through both of them, and...

If it is a bad PS can I install a new one I have , the range for which is 30-50 psi? I cant tell from the manual Tom posted what psi's the pump is rated for. All I can find is on page 2, showing "discharge pressure " of 40 psi. Would my 30-50 work?

I got it running!!!!!! Yahoooo! Finally. On 240V. I dont know what I did differently, but it works. I primed it with a garden hose, and it pumps great. BUT, it doesnt shut off unless I cut the power to it. Now that I (we) got this far, what do I do to the pressure switch to naike it shut off? I...

Wow, so helpful, Tom. Thanks. I should study that! I will let yous know what happens, if I can glean anything from that manual........

I have 240V at the terminals at the PS. Yes, the black hex shaped switch is at 240V. But no V at the PS terminals. So wierd. Gotta be a bad PS, right? BUT, just now, I tried something- I disconnected the 2 wire leads coming from the back of the pump from the PS, and connected them directly to...

Model is Craftsman, 390-2518. SN is not readable anymore. Never requested/demanded that one here must be an electrician. Help offered though is most appreciated, whatever your capabilities are. If you cant help, then thats OK. I was able to post a pic. Not sure if that helps, people. I have no...

got it, here:

Crazy- I tried to upload just one picture of the back of the motor like Tom suggested and I get from this website "the uploaded file is too large for the server to process". Sheeeesh. Tom, When you say "120VAC settings", you mean the simple hex switch to switch back/forth from 120 and 240?

It just hit me- I was looking at the end/rear of the pump wiring and the green ground wire has no connection to anywhere. Could that be the problem? Should I connect a wire to that and ground it where the power source is at the pressure switch, together with the source ground?

So, 240V at the pump itself (bypassing the pressure switch) condemns the pressure switch???

OK, so if one just switches the selector it may require more work like rewiring? That may be my problem. I made no other wiring changes assuming the switch was all that needed to be done. I never knew. I should look at/study the diagram on the label. Feedback appreciated.

remember- in post #1, it ran on 120V before I connected it all up.......

Yes, it has a capacitor. It is a Craftsman, Model # 390.261B, the B may be an 8, hard to read. 3/4 HP. Can I run this on 120V? The switch can be switched to the 120V side. Then I use only one wire, and cap off the other? Think that would help? I dont care what V it runs on, I hardly use it...
