Opening an electric motor

electric motor

I had a pool pump motor given to us that isn't working right.
When the power is switched on the shaft jerks to a fixed position, and stays there unless i give it a manual turn.
Once the motor starts spinning it is labored and gets very hot.
It rotates freely when the power is off.

I am trying to figure out how to open the motor to see what kind of shape it's in.

Here's the label:

I don't see any fasteners or anything obvious, and I can't find any instructions or manuals online.

Edit:

There is no capacitor.
Here's a close-up of the front:

So I put some penetrating oil in as suggested by @EdBeal, and then proceeded to pry the crap out of it to get it open. Took a little work but it did happen.

Unfortunately, the previous owner leaving it out all winter didn't do it much good, and the motor is beyond the amount of money and time I want to put into it.

Fortunately I was able to get a hold of another one that's in much better shape, so the pool is happy again!
