Looks like a 100 series. If the rubber bushings the motor is mounted in rot out it will misalign the shaft and start breaking couplings. Replace them when they get soft.

Is the system still set up as a gravity system, did anyone change any of the piping or the emitters? If it is not changed almost any circulator will work since it is designed to be gravity.

That should be easy to replace. Personally, if I was worried, I would buy a replacement from a hydronics guy. I might keep it on a shelf, just in case , or I might replace it for improved efficiency and an oil free motor. Not so sure I would worry about it dying, but that is just me.

I use the Werner version of the ladder @EBEBRATT-Ed and @Long Beach Ed are referring to — got it at Home Depot. Incredibly useful around the place!

Mine at least has levelling extensions on the legs, so that it can be used even on sloping or uneven ground — never mind things like staircases or other such unhandy spots…

These may sound like stupid questions but did the well guy check to see if the motor is running in the right direction? Did they check the wiring of the motor and also did they make sure that the motor is the correct one; volts, amp draw, and 60 cycles? When the well guy replaced the whole pump, venturi and foot valve did he make sure that all of the piping was not corroded, plugged or have any pin holes? Is the bottom of the well full of mud or debris? Just asking, Since I did not check it myself I have to ask because I have learned to trust almost no one.
