Check of a condition of the block of the engine

PERFORMANCE ORDER

1. Previously the block should be carefully cleared (see. Cleaning of the block of the engine).
2. Make external survey of the block about identification of traces of corrosion, cracks and other damages. Check a condition of a carving of boltovy openings. It will be reasonable to make also testing of the block for existence of the hidden cracks in the conditions of a car-care center workshop with use of the special diagnostic equipment. In case of detection of defects the block is subject to regenerative repair or replacement.
3. Check a condition of mirrors of cylinders.
4. Estimate sizes taking place a konusnost and ovality of cylinders (see accompanying illustrations).

5a. Measure diameter of each of cylinders in top (directly under limit of step wear), the central and bottom sections, at first in the plane of a parallel axis of a cranked shaft (In), then – perpendicular to an axis of the block (And).

5b. Measurement of diameters of cylinders follows makes by means of a telescopic nutromer and a micrometer. Ability is correct to use a nutromer comes not at once – do not hurry up, make some measurements while will not be assured at all of correctness of conclusions.

6. After diameter will be fixed by a nutromer, measure the last with a micrometer (see an illustration).

7. The size of a konusnost of the cylinder is defined by a difference between results of measurements in the top and bottom sections. The difference of diameters in a parallel and perpendicular axis of a cranked shaft the planes is called as ovality. Compare results of check to admissible values (see. Specifications).
8. Operating in the described manner, serially check all cylinders.
9. At detection of appreciable defects or a deviation of results of measurements from standard requirements, the block of cylinders is subject to regenerative machining in the conditions of a car-care center workshop. If in the course of regenerative repair boring of cylinders was made, the engine should be completed with new pistons corresponding repair (with excess) the size.

10a. Check planeness of an interfaced surface of the block (see accompanying illustrations). Compare result of measurements to requirements of Specifications, in case of need give the block to a pro-point.

10b. Measurement make in three directions: on an axis of the block and its two diagonals.

11. If the condition of mirrors of cylinders during performance of check is found satisfactory at simultaneous observance of standard requirements to a form of cylinders and gaps of landing of pistons in them (see. Check of a condition of components of shatunno-piston group), need for a pro-point of cylinders disappears. Will execute only a honingovaniye of mirrors (see Honingovaniye of mirrors of cylinders) enough.
