Check of a condition of the block of the engine

 PERFORMANCE ORDER

1. Previously the block has to be carefully cleared (see Cleaning of the block of the engine).
2. Make external survey of the block regarding identification of traces of corrosion, cracks and other damages. Check a condition of a carving of bolted openings. It will also be reasonable to make testing of the block for existence of the hidden cracks in the conditions of a workshop of car service with use of the special diagnostic equipment. In case of detection of defects the block is subject to recovery repair or replacement.
3. Check a condition of mirrors of cylinders.
4. Estimate sizes taking place of conicity 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 lower 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, make some measurements until are assured of correctness of conclusions at all.

6. After diameter is recorded by a nutromer, measure the last with a micrometer (see an illustration).

7. The size of conicity of the cylinder is determined by a difference between results of measurements in the top and lower 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. Working in the described manner, serially check all cylinders.
9. At detection of noticeable defects or a deviation of results of measurements from standard requirements, the block of cylinders is subject to recovery machining in the conditions of a workshop of car service. If in the course of recovery repair boring of cylinders was made, the engine has to be completed with new pistons corresponding repair (with excess) the size.

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

10b. Perform measurement in three directions: on an axis of the block and two of its 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 to 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 only be to execute a honingovaniye of mirrors (see Honingovaniye of mirrors of cylinders) enough.
