I have a similar manual, Wayne. Could you give me the page number for the above?

I don't know why the numbers aren't the same." I get that figure from McCauley Service Bulletin 227B, dated August 28, 2001 as mentioned in the previous post. This was after an extensive search of Erco, Contenintal and McCauley TCDS's and other pubs. The rest of your comments on re-torquing and wrench calibration are welltaken. I haven't acquired a torque wrench yet, but will bear the beam kind in mind. Percy in Nm, USA
