Yes a motor that works hard will get hot and the harder it works the hotter it will be but if it gets too hot to hold a hand against there is probably something wrong.

Should the motor end of the pump be warm/hot to touch?

The motor should be warm to the touch when operating normally. The pump does use the flowing water to help cool the motor so if it is running but no water is being circulated it can get hot.this is not good for the motor so check pipIng and filters regularly for any obstructions.

How do I wire a Polaris PB4-60 in the USA (115V)?

I am not sure if this will help you out any, but here goes:
Line1 & Line 2 are your Hot Power Wires coming into the motor.
It does not really matter which wire goes to which post of the motor.
This will remain true if you are bringing in 110-115-120 (these are all the same, people just refer to them differently) which also is referred to at times as "Low" voltage, and the same goes for 220-230-240 (again, referred to differently) which is referred to at times as "High" voltage.
Whether bringing in Low voltage or High Voltage, the wires you bring in will number only three:
  • Ground
  • Hot
  • Hot (potentially Hot)
Low Voltage (115) will have:
  • 1 Absolute Hot Wire = Line 1. Normally Black
  • 1 Potentially Hot Wire = Common/Nuetral Line 2, normally White
  • Ground/Earth = Normally Green
High Voltage (220) will have:
  • 1 Absolute Hot Wire - Line 1, Normally will be same color as Line 2 or Black/Red
  • 1 Absolute Hot Wire - Line 2, Normally will be same color as Line 1 or Red/Black
  • Ground - Green
In either of the above voltages, it does not matter which wire goes where, as long as a Hot wire goes onto Line 1 and the other "Hot or Potentially Hot, if 110", goes onto Line 2. Do not put a Hot wire anywhere else and Do Not put a Ground wire on either Line 1 or 2!

Most Motors are coming out of the factory wired for High Voltage Set up (220), so you will have to move some wires or a terminal block, to set the motor to operate at "Low" voltage (115). These motors are "Dual" Voltage, they have the capability to run either 110 or 220. But they don't magically know which voltage is being supplied.

Good Luck

Motor clicks off after getting hot?

This is a normal function of any pump. When a motor gets too hot it has a thermal cut-off inside so it won't burn up the pump.
Once the motor has cooled down it will come back on.
Look around the motor to make sure it has plenty of ventilation. If it does and the motor keeps shutting down on you I would replace it or take it to a motor repair shop and get it looked at.
There will be something wrong with the motor and that point.

The motor works sometimes but it is very hot.

It's normal for these to run a little hot, a couple things may cause your motor to run hotter than normal.
1. Bad bearings - a local motor shop can take it apart and replace them for around $50. Usually you can tell by a high pitched grinding or squealing noise
2. Wrong impeller - if your impeller is not the correct size for your HP you will be moving too much/not enough water through your pump causing stress to your motor
3. Blocked airway - you can use a can of air on your motors intake grille while it is running to blow out any clogs, if you have low airflow on the exhaust it probably means the airway is blocked

New a.o.smith 2.5 motor. hooked up same as old. my question is should i have power on all three legs?

That is a 220V pump so you should have two "hot" legs and one return leg. Normally the red and black are hots and the return is white.

Intermatic c8866 1 hr cycle timer- wiring- I have 2 hot legs & neutral. Neutral goes to the clock, one hot leg goes to switch common, what does 2nd hot go to- normally open or normally closed? this is...

You have C8866 repeat cycle pump, that repeats the same program each hour.

Your well pump is 240Volt which is why you have two Hot wires.

One Hot wire connects to COM terminal.
Your Neutral wire connects to Clock terminal.
This will power the clock motor.

One hot wire to Load connects to NO normally open terminal.
This terminal turns ON when timer turns ON.
NC terminal is ON at all times, EXCEPT when timer turns ON, and then NC terminal turns OFF

Your second Hot wire runs directly to pump and does not connect to timer.
See diagram below:

I have a new 1 hp hayward on my new inground. It is on it's on electric meter and my bill has been $130/month for the pump alone. It's very hot to the touch. Is any of this "normal"? Everyone that i...

Yes, it is normal for a motor to be hot to the touch.

The motor draws on the order of 8 amps at 220 volts. The calculation:

Watts = Volts x Amps = 220 x 8 = 1760 watts

At, say $.20 per killowatt hour, the cost to run the pump 12 hours per day for a month =

1760 Watts x 12 hours/day x 30 days / 1000 watts x $.20 = $127

You can substitute your actual numbers for the variables, to get an accurate cost.

Foltec 4012-10 motor get hots and kicks off

Sounds like a seized bearing. Many times the motor boosts its torque output to get over the initial inertia. and if the bearing seized, the motor running at normal capacity would not be strong enough to rotate. thus causing the rotor to stall and hence the motor getting overheated.
