Fig. 447. Measurement of diameter of an opening of the cylinder. Insert a nutromer vertically into an opening of the cylinder and gradually lower it along a cylinder opening in perpendicular situation concerning walls





For measurement of openings of cylinders the nutromer (fig. 447) is required . We would like to warn you what to use such device not easy as at an inclination of measuring tips you receive incorrect results of measurement. If you have no nutromer or you are not able to use it, you cannot carry out the following works. In this case it is better to address on HUNDRED.
Measurements of an opening of the cylinder should be carried out in the longitudinal and cross-section direction. By means of a nutromer measure diameter of the cylinder at distance of 10 mm from the upper edge of an opening of the cylinder, and then at distance of 10 mm from bottom edge of an opening of the cylinder. Carry out one more measurement in the center of an opening of the cylinder. Six results of measurements in total will turn out. Write down all received values and compare them to the data provided in the table of adjustments and control. Remember that the nutromer in an opening of the cylinder should settle down under the correct corner because even the slightest distortion conducts to receiving incorrect results of measurements. If the nutromer is inserted, as it is shown on fig. 447 , it can bend to the right or to the left, during carrying out measurements. The arrow of the device thus will constantly come back to average size about which there is a speech at measurement of diameter of an opening of the cylinder.

Fig. 448. Scheme of measurement of openings of cylinders. Carry out measurements in each opening of the cylinder in the directions A (the cross-section direction of measurement) and B (the longitudinal direction of measurement). Measurements should be carried out in three places, namely on depth 1, 2 and 3





Write down all 6 results for each cylinder. If you draw the scheme similar to fig. 448 , results of measurements for descriptive reasons bring in it better. Diameter of the cylinder should not differ more anywhere than 0,08 mm from the nominal size.

Fig. 449. Measurement of diameter of the piston





To measure a gap of pistons, measure diameter of pistons (fig. 449) and write down the received values of all diameters of pistons. For definition of a gap it is necessary to calculate a difference between diameter of openings of cylinders and diameter of pistons.
In the engine pistons of two increased (repair) sizes for what it is necessary to chisel the block of cylinders can be established.
