At installation of details with an anticorrosive covering it is necessary to clean interface surfaces. On interface surfaces there should not be traces of an anticorrosive covering and fat.
The inhaling moments are resulted for not greased bolts and nuts.
Carrying out welding or рихтовочных works with bearing or directing elements of a suspension bracket is inadmissible.
Avoid following influences on screw springs: blows by a hammer, hit of drops of metal at the welding, the subsequent drawing of colour designations.
In area винтовый springs and amortisation racks do not spend any welding and grinding it (is sharp) works. If necessary close a screw spring / amortisation racks.
It is forbidden to move cars without the established power shafts since the bearing of a nave of a wheel in this case is damaged. If, nevertheless, the car it is necessary to move, observe the following operations procedure.
Establish instead of a power shaft the external hinge.
Tighten the external hinge with the moment 115 Н·м (screw M14) or 200 Н·м (screw M16).
Rezinometallichesky hinges (sajlent-blocks) have the limited working range of twisting. Therefore carving connections of levers tighten only on the empty car
If check of corners of installation of wheels is necessary to the car still to tighten screws and the nuts unscrewed at installation of corners, it is necessary only with the demanded moment. After performance of works on exhibiting of corners of installation of wheels hold on screws and nuts on a demanded corner доворачивания.
