I was using a torque to yeild computerised wrench back in 78 , we had to pay a royalty every time it was used !!

Yeah, we didn't use torque to yield 'cos we needed elasticity in the joints. TTY was just a tad too much ..

When we did use it in preliminary tests, 'cos that was the obvious route, the joints failed prematurely compared to joints that were tightened with the bolts done to a short way before yield.

Did you use the Ingersoll Rand wrenches? I used to have to calibrate and service them too.

Not sure what make , I had a feeling it was american . It was air driven , and if didnt get a green at end had to remove bolt and start again . we were using on cylinder heads

Yeah cylinder heads work best with TTY, but because our joints were rotational with different forces, TTY wasn't suitable.
