I know somebody that, when it needed to remove a packnut like that, it took a chiesel and "open it", then tried to unscrew one by one the washers.
Yep, that's single use only.
That's rich! Like any of the torque tools have the capability to measure at 0.5% precision! Because that's what an exact 221 value would imply.On my 2006 with drums the Ford torque specs was 221ft-ft-lbs.
