Check of a condition of the block of the engine


1. Previously the block has to be carefully cleared (see the Section 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:

a) Measure diameter of each of cylinders in top (directly under limit of step wear), the central and lower sections in the plane of a parallel axis of the cranked;
b) Now measure diameters at the same three levels, but in the plane, a perpendicular axis of the block;
c) 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 in each of the planes is called as ovality.
d) Compare results of check to nominal rates (see Specifications).

5. Working in the described manner, serially check all cylinders.
6. 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.
7. 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 the Section 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 their mirrors (see Honingovaniye's Section of mirrors of cylinders) enough.

8. Check planeness of the block surface interfaced to a head. Compare result of measurements to requirements of Specifications, in case of need give the block to a pro-point.
