3.8.4. Cylinders

Measurement of cylinders нутромером

1 – нутромер;

2 – installation нутромера on a zero on calibre A.96137

The scheme of measurement of cylinders



And and In – measurement directions; 1, 2, 3, 4 – numbers of belts

Marks of dimensional group of cylinders on the block and conditional number of the block of cylinders

Red arrows – marks of dimensional group of cylinders on the block of cylinders.

Black arrow – marks of conditional number of the block of cylinders.

Diameter of the cylinder is measured нутромером (fig. Measurement of cylinders нутромером see) in four belts, both in longitudinal, and in a cross-section direction of the engine (cм. Fig. the Scheme of measurement of cylinders). Calibre А.96137 is applied To installation нутромера on a zero.
The prevention

Block cylinders on diameter are broken through 0,01 mm into five classes: And, In, With, D, E.Klass of the cylinder is marked on the bottom plane of the block (Marks of dimensional group of cylinders fig. see the block and conditional number of the block of cylinders). On the same plane, and also on covers of radical bearings conditional number of the block of cylinders which specifies in an accessory of covers to the given block is branded.


In a zone of a belt 1 cylinders practically do not wear out. Therefore on a difference of gaugings in the first and other belts it is possible to judge size of deterioration of cylinders.

PERFORMANCE ORDER
1. Check up, whether exceeds deterioration of cylinders as much as possible admissible – 0,15 mm.
2. If the maximum size of deterioration is more 0,15 mm, chisel cylinders till next repair size of pistons (the increased on 0,4 or 0,8 mm), having left an allowance of 0,03 mm for the diameter under хонингование. Then отхонингуйте cylinders, maintaining such diameter that at installation of the chosen repair piston the settlement backlash between it and the cylinder was 0,05–0,07 mm.
