00 Tightening torque Values are directly specified for out-of-standard tightening torques for bolts and nuts. Where there is no specified figure for tightening torque, follow the table covering standard tightening torques. When the item is to be tightened in a wet state, “wet” is indicated. Where there is no indication, read it as dry. Units Tightening torques and other parameters are given in SI* units with metric units added in brackets { }. Values in engine specifications, performance curves, and other items taken from official approval documents are given only in metric units. *SI: Le Systиme International d’Unitйs Example:
