5.14. The block of cylinders - condition check1. At detection of outer defects (cracks and chips), repair the block or replace. It is recommended to check existence of Internal defects in the block of cylinders for what it is necessary to hand over the block in a car-care center workshop.
2. Check ovality and a konusnost of cylinders, having measured diameter in three planes, in the directions parallel and perpendicular axes of the block (photo). If results differ from standard, it is necessary to hand over the block in a repair workshop. After restoration of the block pistons and rings of the repair sizes will be necessary.
3. If a condition of cylinders accepted, wear of the cylinder and a gap between the cylinder and the piston do not exceed the established norms, cylinders it is required otkhon-ningovat (photo). Works are recommended to be carried out in car-care center.
4. Check deformation of the demountable plane of the block of cylinders (photo). If the deviation from the plane exceeds norm, the block follows прошлифовать in a car-care center workshop. The thickness of a material removed from the block should not exceed thickness of the material removed from a head. If the total size by which decreased the block an igolovka after polishing exceeds 0,2 mm, it is necessary to replace a head and the block.
