I tried all of this and still the same problem....could it be that my belt is too old and sitting in the pully to much ....just a though

Anything is possible. How easy was it to turn the arbor by hand?

You say the motor runs without a load. What happens if you let is spin free for awhile and then with a rag you try to stall the spining shaft is it easy to stop?

There has to be something you aren't telling us.

Either to hand spin the arbor you have to use a lot of force, or the motor really never runs right without a load. Or the circuit you think is good is not so good.

Yes the belt with a set can cause problems but I have seen them more as vibration than stalling the motor and poping the breaker.

You said you are new at this and those procedures that normally work do not. This makes me wonder.

Maybe you are not oiling those points that need to be oiled.

Maybe you need to spend a few minutes watching this Sawdust Session and then we can start over.

Hi there the arbour is very easy to turn by hand and the motor I had it taken to a professional yesterday to have it tested and he said everything with the motor was perfect ......

and going to watch this video thanks

Watch the video but if the arbor is easy to turn and the motor checks out and the whole runs fine without the belt on the motor then one of two things are happening.

One when the belt is hooked up something is turning and hitting a wire and shorting the whole thing out

or

The breaker is bad and any load on it is causing it to pop.

The load from an easy to turn arbor will not cause enough current draw to trip a normal 20 amp breaker.

Double check what you have told us.

First with just the belt removed make sure the motor runs. Shake the machine a little and see if maybe something might be hitting bare wire.

Next double check the arbor turns fairly easy.

Third hook everything up and try it. If the breaker pops

Try another circuit

Let me know what you find. Don't assume anything do each step in order.

Are you SURE there's nothing else on that circuit?

Hi, I watched the video and oiled everything up and still kicking off my breaker and I find also that my motor is running really hot...

Power cords do not plug into breakers.
Power cords plug into receptacles.
More than one receptacle may be wired to a single breaker.

Does the motor run hot with the belt disconnected?
Can you hear the start switch clicking?

Older mark v is IMHO contradictory. What do you have? What does the vent plate say?

Does the motor hum loudly?

What did the 'professional' do to 'test' the motor?

Too many things do not make sense. When that happens, often assumptions are clouding the view.
