I have a Bailey Olympus 462 (2010) in the instructions the bolt tightness is shown as 110 NM, I have had it serviced and the technician showed on his report that he had tightened the bolts to 130 NM. I commented on this and his reply was that the current recommendation from manufacturers was for between 120 to 130 NM . The instruction book states that it is as dangerous to over tighten the bolts as to under tighten them. Does anyone know whether the recommendation has been changed.
