Stopping the surface of each connecting rod between the fillets is carried out with the above checks until their ovality, cones and non -parallelity of the shaft axis will be reduced to the values allowed for the renovated shaft, and when checking for the paint according to the conductor or using the stains, the stains will be distributed evenly on the entire surface of the neck with a density of at least three spots on a square with a side of 25 mm%.
Strap -telly sawing of rogue necks, as well as their grinding, is performed in the same way as in the indigenous necks.
In cases where the length of the existing level does not allow you to install it on a connecting rod neck, you have to apply other methods of checking its parallelity of the shaft axis. One of these methods is a level check using a connecting rod. In this case, the connecting rod is installed on the neck, in which the belt was pre -sawed opposite the annular lubricant groove on the inserts (bearing), and a locksmith level is installed in the hole of the upper head of the connecting rod or the frame level is applied to the side surface of this bearing. The tilt of the connecting rod neck is checked according to the level of level, taking into account the deviation of the surface at which the locksmith level is set, from parallelism – or surface, to. which is applied by the frame level from perpendicularity – the surface of the connecting rod bearing resting on the neck. For this purpose, a connecting rod of a repair diesel engine with an old Babbitic filling of a connecting rod of a connecting rod is used. At the same time, the surface of the top liner of the connecting rod bearing should be torn so that it adjacent to the neck in the upper part of the filling symmetrically relative to the axis of the connecting rod is about 45 ° and that its deviation that forms on this part of the pouring from the parallelity of the formation of the back of the head (no sticky) did not exceed 0.02- 0.03 mm per 100 mm length. From the upper head of the connecting rod should be removed or a replaced sleeve is applied.
