Never, ever, under any circumstances run an engine with the belt off.
It's a safety issue!!
To see if the clutches are shifting out properly, do the "sharpie" test.
Remove belt, with a sharpie draw a straight line from the center of both clutches to the outer edge. Put the belt back on and run the sled under load.
Then you shut it down and remove the belt. You can then see where the marker line is rubbed off the clutches. If they are not shifting out there will be some line left and this will point to which one needs the service.
