Procedure and order of tightening of threaded connections

Tightening of the most part of threaded connections should be made with the efforts determined by requirements of the Specifications provided in the beginning of each Chapter of this manual (it is necessary to understand the torque enclosed to it when tightening as effort of tightening of fixture). Below the effort of tightening will be called also fixture inhaling moment. Tightening with excessive effort can lead to violation of integrity of fixture whereas the nedotyagivaniye leads it to unreliability of connection of the interfaced components. Bolts, screws and hairpins, depending on material of which they are made also diameter of a carving part usually have strictly certain admissible moments of an inhaling, many of which as it was already mentioned above, are given in Specifications at the beginning of each Chapter. Strictly adhere to the provided recommendations about the moments of an inhaling of fixture used on the car. For tightening of fixture which is not mentioned in Specifications it is necessary to use the map of the admissible moments of rotation given below. The values given in the table are focused on fixture of classes of durability 2 and 3 (more high-class fixture allows tightening with big effort), besides, it is meant that tightening dry (with an ungreased carving) fixture in a steel or cast (not aluminum) detail is made.

Fixture located on perimeter of any detail (such as bolts of a head of cylinders, the pallet of a case and various covers), in order to avoid deformation of a detail has to be given and drag on in strictly certain order. The order of tightening and an otdavaniye of such fixture is given in the corresponding Heads of the Management. If the special order is not stipulated, then in order to avoid a curvature of a component it is necessary to adhere to the procedure described below.

At the first stage all bolts or nuts have to be tightened by hand. Further, each of them has to be in turn held on on one whole revolution, and transition of odes of one bolt / nut to another has to be carried out in a diagonal order (cross-wise). Further, having returned to the first bolt / nut, it is necessary to repeat the procedure in the same order, tightening fixture for a half-turn. Continue to act in the same manner, tightening each bolt / nut this time already on a quarter of a turn for one approach until all of them are not tightened with the required effort. At fixture otdavaniye it is also necessary to adhere to the described procedure, but working upside-down.
