4.2.7 Collars 6 should be installed at the guide bushings of the induction valves.
4.2.8 Cotters 4 should be fitted tight to the surfaces of the valve rods 3, 5 and cap liners
2. Free removing of the caps 1 and cotters 4 relatively to the valve rods after the assembling is
not permitted.
4.2.9 Gaskets of the eduction manifold should be installed with the wider side of the
metal edge strip to the manifold flanges.
4.2.10 Nuts of the water pipe fasteners, eduction and induction manifolds should be
tightened beginning with the middle flanges.
4.2.11 Nuts of the water pipe fasteners should be tightened with the moment of force
from 14 to 24 Nwm (from 1.4 to 2.4 kfg m).
4.2.12 Nuts of the eduction and induction manifold fasteners
should be tightened with the moment of force from 36 to 48 Nwm (from 3.6 to 4.8 kfg m).
4.2.13 Installing the thermostatic regulator in the right and left water pipe thermostatic
drainage valve should be located above with the pipe locating corresponding the pipe location
in the engine.
4.2.14 Before screwing of the plugs of the water pipe and tap (if it is available) for two -
three threads one should lubricate the plug and tap threads with the sealing"Anagerm-100" or
"Anagerm 114".
4.3 Pistons with connecting rods and rings
4.3.1 Pistons and connecting rods which were in operation should be from one set with
the cylinder liners in which they were installed before the disassembling. New pistons should
be of one dimension grade with the cylinder liners.
4.3.2 New pistons and connecting rods should be marked with index numbers of the
cylinders corresponding the marking at the liners which are chosen for the pistons.
Pistons should be marked at the bottom at the side opposite to the marking of the
dimension grade of the piston at that distance from the marking to the generator of the
external diameter of the piston and combustion chamber should be no less than 7 mm.
Connecting rod and its cover should be marked at the side surfaces of the head in the
place of joint from the side of the short bolt of the connecting rod cover.
4.3.3 Assembling new piston with the repaired connecting rod if old marking of the of
the cylinder index number at the piston does not comply with the marking at the piston should
be replaced by the new one.
4.3.4 Piston pin 5 (picture 4.3) should rotate free without constraints in the bushing of
