In the absence of such drawings, it is recommended to be guided by the following requirements when processing landing belts and supporting bacter.
The ovality of landing belts should be no more than admission to the diameter of the belt. The outer diameter of copper sealing belts in the bushings of two-stroke diesel engines should be larger than the opening with it by 0.02-0.06 mm, and the outer diameter of the upper support of the tower is less than the diameter of the opening of 0.002-0.003 of this diameter of this diameter. On landing belts, the sleeve can be allowed to be a sink up to 0.2 and the largest measurement of up to 0.3 wall thickness, but not more than three such shells on each belt. The output of the shells into the edges of the grooves for sealing rings is not allowed.
