Keep in mind that the amperage rating and the service factor (that's the 1.0 next the SF) determine the actual power of the motor. The 1.0 SF means it's an Up rated motor, actually smaller than whatever Horsepower they are claiming.
Make sure that you match up the new one to those ratings and you'll be fine.
You could just take that motor in to a Grainger or whatever you have close to you and match it up.
Oldred is absolutely right that the capacitors do sometimes blow, if that's the only problem, make sure you label the terminals before pulling the wires off, or you'll be scratching your head like crazy trying to figure out how to reconnect them.
One other thing is to see if it has an adjustable pressure switch. It may have been turned up extremely high, might have caused the problem with the motor, making it run too hard in order to attain a very high pressure.
No matter what, it was a good buy!
