Well, using the good ole arm torque wrench, if you were using a 6" wrench/rachet, apply about 80 lbs of force. If you had a 12" wrench, think of it as doing a 40lb dumbell press. etc. etc.
The worse thing that could happen would the nut would fall off and the bolt would come out. You'd still have 3 motor mounts holding the motor in place
