Big T,
What you are seeing is probably burnt out contacts on the capacitor START switch. If there is a motor shop (electric), take it to them.
At the very least, blow the guts of the motor out with compressed air. The centrifugal switch sometimes gets hung up with funk.
I'm looking at a single phase 5 hp motor right now....it is huge. I'll bet your ODP motor is way over rated and is working itself to death.
My guess is that your IR compressor and motor were really made in the land of the great wall!
That's my take on the situation.
