After this check, the frame is attached to the subframe, tightening the bolts diagonally, and again with the help of a ruler and probe are convinced of the absence of deformation of the upper surface of the frame.
The installation of the foundation frame draws up an act indicating the size and direction of its inclination in the longitudinal and transverse directions.
The volume of work on the laying of the crankshaft includes a fitting of liners on the beds of the foundation frame and the lids of the indigenous bearings, the cooking of the Babbit filling of liners along the indigenous shaft shaft with the necessary straightness of the axis of the shaft and it in relation to the upper supporting surface of the foundation frame, as well as with the installation of the required diametral mounting gaps between shaft neck and liners.
After the thick -walled liners are previously hidden (to remove the foundry of the foundry), the quality of their filling is cleaned in the joints and the quality of their filling, burrs on their linen and beds are removed, they are wiped and checked by the occipital part to the beds and paint of the probe and paint. ” if necessary, performing all these works in the same way as the liners of the connecting rod bearings. In addition, the adjacent to the ends of the nest is checked at the stubborn bearing liner. At the same time, if the gap between the beams and the nest exceeds 0.1 mm, put on or welded to the insert a steel gasket and a buckle to get a tight fit to the nest.
Then the occipital parts of the liners are soldered on the beds, the joints are shared in the plane of the connector, the lubricants are bred, and the lubricants and refrigerators are processed in the same sequence, as indicated for the liners of the connecting rod beeps, which are not in the collection with the connecting rod, and with the fulfillment of the same requirements regarding the fit of the occipital part and joints on the paint.
