Procedure and order of a tightening of carving connections

The tightening большей should be made parts of carving connections with the efforts defined by requirements of Specifications, resulted in the beginning of each Chapter of the given Management (it is necessary to understand as effort of a tightening of fixture put to it at a tightening a twisting moment). More low the effort of a tightening will be called also as the moment of an inhaling of fixture. The tightening with excessive effort can lead to infringement of integrity of fixture whereas недотягивание it conducts to unreliability of connection of interfaced components. Bolts, screws and hairpins, depending on a 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 already it was mentioned above, are resulted in Specifications in the beginning of each Chapter. Strictly adhere to the resulted recommendations about the moments of an inhaling of fixture applied on the car. For a tightening of the fixture which has been not mentioned in Specifications it is necessary to use the map of the admissible moments of rotation resulted more low. The values resulted in the table are focused on fixture of classes of durability 2 and 3 (more high-class fixture supposes a tightening with the big effort), besides, it is meant that the tightening dry (with not greased carving) fixture in steel or cast (not aluminium) a detail is made.

Any fixture located on a perimetre detail (such as bolts of a head of cylinders, the pallet картера and various covers), in order to avoid detail deformation should be given and be tightened in strictly certain order. The order of a tightening and отдавания such fixture is resulted in corresponding Heads of the Management. If the special order is not stipulated, in order to avoid a component curvature it is necessary to adhere described below procedure.

At the first stage all bolts or nuts should be tightened by hand. Further, each of them should be by turns held on on one complete revolution, and transition of odes of one bolt/nut to another should be carried out in a diagonal order (cross-wise). Further, having returned to the first bolt/nut, it is necessary to repeat procedure in the same order, tightening fixture for a half-turn. Continue to operate in the same manner, tightening each bolt/nut this time already on a turn quarter for one approach until all of them will not appear tightened with demanded effort. At отдавании fixture as it is necessary to adhere to the described procedure, but operating upside-down.
