2.2.9. Removal and installation of a head of the block of cylinders (4G63)
Removal of a head of the block of cylinders
Turn on bolts in 2 or 3 stages in the sequence specified in drawing, and then remove a head of cylinders assembled.
At an otvorachivaniye of bolts of fastening of a head of cylinders be careful not to damage or deform directing tubes of spark plugs as they are not delivered separately.
Installation of laying of a head of cylinders
By means of a special scraper remove the remains of old laying of a head of cylinders from the block of cylinders.
At carrying out this operation do not allow hit of a material of laying or other extraneous particles to canals of system of cooling and greasing system.
Degrease adjacent surfaces of laying.
At installation check coincidence of all openings on laying and a head of cylinders.
Be convinced available the corresponding identification label for this engine on new laying of a head of cylinders.
Put laying of a head of cylinders on the block of cylinders an identification label up so that it was located from final valves.
At installation of bolts of fastening of a head of cylinders be convinced that the length "And" each bolt is in limits of admissible value.
If the length "And" exceeds maximum permissible value, it is necessary to replace bolts.
Maximum permissible value "A": 99,4 mm.
Grease with a thin layer of engine oil a carving and washers of bolts of fastening of a head of cylinders.
If the washer of a bolt of fastening of a head of cylinders was replaced, establish it the party with a facet up, as is shown in drawing.
Tighten bolts according to the procedure specified below.
Always wrap a bolt on a corner strictly equal 90 °. Otherwise the bolt of fastening of a head of cylinders can be weakened (reliability of a gas joint) will not be provided.
If a bolt will tighten on a corner bigger 90 °, it is necessary to weaken and repeat completely it all operations, since point 1.
Installation of a fuel hose of a high pressure
Grease ring sealing laying by a small amount of fresh engine oil.
It is not allowed oil hits in a fuel collector.
Slightly turning a flange of a fuel hose to the right – to the left, carefully insert it into a fuel collector not to allow laying damage. After installation check, that the hose turned in a fuel collector smoothly.
If the flange of a hose jams at turn, as the reason damage of ring sealing laying can serve. Disconnect a flange (assembled with a hose) from the fuel
collector also check laying on absence of damages, then insert it back and check smoothness of a povorachivaniye.
Installation of asterisks of camshafts
Fix asterisks of camshafts from a pro-collar by means of the special bifurcate holder and special bolts.
Wrap fastening bolts звездочеки camshafts the nominal moment.
Inhaling moment: 89 ±9 N · m.
Establish an inlet branch pipe of system of cooling and the thermostat case assembled.
Establish the top cover of a belt of a drive of GRM.
Establish a final collector.
Establish the air filter assembled.
Fill in cooling liquid and engine oil.
Adjust a tension of a belt of a drive of hinged units.
