The design of the engine block «M62» shown in fig. 4.3 and fig. 4.4.
Cylinder block (pic. 4.3) – with dry thin-walled cast iron sleeves, made of light alloy, the sleeves of which can be repaired (boring). The cylinder block is made entirely of aluminium-based light alloy. The sleeves are installed during the block manufacturing process and cannot be replaced. Location (collapse) blocks of the V-shaped engine - 90°. Bottom Block (crankcase) made five nests-supports for liners of main bearings of the crankshaft.
The main bearing caps are finished with the block, so they are not interchangeable. In case of wear or minor damage, the cylinder mirror can be restored by honing or grinding in the conditions of a car service station (service station), followed by the installation of pistons of intermediate or repair size.
The diameter of the cylinders is measured by an inside gauge in three zones in mutually perpendicular directions, at a distance of 10 mm from the upper and lower edges and in the center of the cylinder.
