2.2.8. Removal and installation of a head of the block of cylinders (4G64, 4G69)
Dump residual pressure from топливопровода a high pressure.
Merge cooling liquid.
Merge engine oil.
Remove the air filter assembled.
Disconnect a cable of a pedal of an accelerator.
Remove a final collector.
Remove the top cover of a belt of a drive of GRM.
Remove an inlet branch pipe of system of cooling and the thermostat case assembled.
Uncover heads of cylinders.
Removal of an asterisk of a camshaft
Turn a cranked hall clockwise before combination of adjusting labels on an asterisk of a camshaft and an asterisk of a cranked shaft with the corresponding adjusting labels, and establish the cylinder No. 1 piston in VMT of a step of compression.
Turn a cranked shaft only clockwise.
Take a cap and screw a special core in an opening of an arm of fastening of the hinged equipment so that it rested against a flute on the lever of a natyazhitel.
Slowly roll a special core, combining an opening "In" on the case of an automatic natyazhitel with an opening "And" on a rod of a natyazhitel.
Roll a special core with a step no more than 30 ° in a second. If a core to wrap at once at full capacity, its deformation because of the complicated moving of a rod of a natyazhitel is possible.
By means of a tape collar or a wire fix a belt of a drive of GRM on a camshaft asterisk in a position shown in drawing.
Fix a camshaft asterisk from a pro-collar by means of the special holder and bolts.
Unscrew a bolt of fastening of an asterisk of a camshaft.
Do not rotate a cranked shaft after removal of an asterisk of a camshaft.
Before removal put adjusting labels of initial provision of a hose of a radiator and a collar. Disconnect the top hose of a radiator.
On series 4G69 engines before a detachment of a fuel hose of a high pressure, remove its arm.
Remove a clamp of a fuel hose and pull it in the direction specified by an arrow in drawing.
If the clamp of a hose of a high pressure was released, establish it into place after a hose detachment.
Removal of the pump of the hydraulic booster of a steering assembled with an arm
Remove the pump of the hydraulic booster of a steering assembled with an arm together with the hoses connected to it.
The removed pump of the hydraulic booster of a steering assembled with an arm and hoses adhere a wire and place in such place where it will not hinder at removal and installation of a head of cylinders assembled.
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 a fuel collector and check laying on absence of damages, then insert it back and check smoothness of a povorachivaniye.
Connection of the top hose of a radiator
At connection of the top hose of a radiator put on it a ledge a branch pipe against the stop then tighten a collar.
It is necessary to establish a collar of a hose always in situation in which the collar was established at removal. Therefore before installation of a collar combine adjusting labels on a collar of a hose and a radiator hose, then connect it.
Installation of an asterisk of a camshaft
Fix a camshaft asterisk from a pro-collar by means of the special bifurcate holder and special bolts.
Wrap a bolt of fastening of an asterisk of a camshaft the nominal moment.
Inhaling moment: 89 ±9 N · m.
After completion of installation of details execute the following operations:
On engines of a series 4G69 establish a cover of a head of cylinders.
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.
On engines of a series 4G69 connect a cable of a pedal of an accelerator.
Establish the air filter assembled.
Fill in cooling liquid and engine oil.
Adjust a tension of a belt of a drive of hinged units.
Adjust a cable of a pedal of an accelerator.
