The cylinder block with installed parts: 1 - a bolt, 25 Nm; 2 - Coolant pump pulley; 3 - bolt 20 Nm; 4 - the coolant pump; 5 - O-shaped sealing ring is always replaced with the new; 6 - dipstick with guide tube; 7 - blocking drainage of oil 5 Nm; 8 - knock sensor number 2 (to adjust the ignition timing); 9 - screw 5 Nm; 10 - a cover of the oil pump; 11 - O-shaped sealing ring is always replaced with the new; 12 - drive the oil pump; 13 - the block of cylinders; 14 - an intermediate shaft; 15 - shim, the inscription on it should be facing up; 16 - bolt 10 Nm; 17 - O-shaped sealing ring is always replaced with the new; 18 - oil pan gasket; 19 - the thermostat; 20 - bolt 10 Nm; 21 - O-shaped sealing ring is always replaced with the new; 22 - the gauge of frequency of rotation of the crankshaft; 23 - bolt 5 Nm; 24 - bolt 20 Nm; 25 - O-shaped sealing ring
Wash the cylinder block 13 (Fig. 69)
and clean the oil channels. Blowing and dry compressed air, inspect the engine block. The cracks in the pillars or other areas of the cylinder is not allowed. Be sure to remove all traces of cleaning agent from the cylinder.
Measure the gap between the side surfaces of the cylinder and piston (see. P. 2.4.2).
The difference of the measured values of the inner diameter of the cylinder between the upper and lower belt indicates the taper of the cylinder bore, and the difference values between the longitudinal and the transverse direction - on roundness. Bore nowhere to differ by more than 0.08 mm from the nominal size.
The motor can be mounted two pistons repair sizes, which respectively have to bore the cylinder block (see. P. 2.4.2).
Fig. 46. Checking cylinder head for distortion using a ruler and measuring probe
Check deformation of the surface of the cylinder block (for the cylinder head, see. Fig. 46),
which measure the magnitude of the gap of the cylinder in the longitudinal, transverse and diagonal directions with pomoschyu set of shims. The gap should not exceed 0.10 mm. Before measuring, make sure that the surface of the cylinder is thoroughly cleaned, and there are no foreign bodies between the probe and the surface of the cylinder.
