Whether the specified Drehmonentstärke of almost 1,400 Nm true is questionable

On the quality there is certainly nothing to complain about, which I believe to 1a. Anyway, the best I had in use to this day. How should that affect the specified torque of almost 1,400 Nm in practice has not yet been opened up to me. After all screws have been tightened to 200 Nm, can be personalized with the impact wrench and its force of 1400 Nm is still not solved.

So I bought air hoses with 15 mm diameter for the compressor. Unfortunately, this also did not result in improved solubility characteristics.

Example is the screw (Beetle Engine) the flywheel, even with this "muscle man" here I could not solve it. But that's why I had bought but the part. The NM indicated should have sufficient thickness ....

I had to borrow an impact wrench of !!! 4000 Nm !!! Force developed to solve the screw. But that it went like butter.

Will keep the impact wrench to anyway, as I said, the quality is impeccable.
