Every so often I have to assemble a stator/s that are 1m in diameter and weighs about 750Kg's, it requires compression to a pre torque of 400Nm then baking to 200C and then a final torque to 550Nm. Wouldn't be so bad but there are 48 Nuts to torque and the last one's to be assembled was last summer. We need at least 3 people to take turns in doing this and it's a real arm, shoulder, back, leg....everything killer! And we had two to do, but on different days
