Repair and operation of the car

Removal and installation of a head of cylinders

Before coming to work, hope for the cooling full of the motor.

Removal

ORDER OF REALIZATION

1. Bring the piston of the first cylinder in the provision of VMT of the end of a step of the compression (to see the Reduction of the piston of the first cylinder in the provision of the superior dead point (TDP)).
2. Desconecte a negative wire of the battery.

If the stereosystem established in the car if it equips of a security code before desconectar the battery they secure what has the correct combination of the entry of the system sound in the action!

3. Empty the system of cooling and result when they were taken of spark (to see the Front Regular maintenance).
4. Withdraw the purifier of air with a sleeve of air entry (to see the Head of the system of provision of Power and launch).
5. Take away belts of driving of auxiliary unities (to see the Front Regular maintenance). Otboltite to direction bomb also takes it to the part, without desconectar hydraulic lines, soon they withdraw an arm of the bomb of direction (to see the Chief Podvesk and driving).
6. Desconecte a thread of a gas pedal and deposit the pressure in a system of provision of power (to see the Head of the system of provision of Power and launch).
7. Desconecte the next hoses and lines (to see Chapters of the system of provision of Power and launch and the System of control of the motor):
   a) Hose of supply of fuel;
   b) Hose of system of capture of evaporation of fuel (EVAP);
   c) Ventilation of hose (tube of branch of a sapun);
   d) Hose of PCV.
8. Desconecte perepuskny a hose of system of cooling, a hose of a heater and the hose of better electric heater (to see the Head of the system of Cooling and heating).
9. Desconecte an electrical system of the next component ones:
   a) Injectors of injection of fuel;
   b) O sensor of the temperature of cooling the liquid (CTS);
   c) O switch of sensor of the temperature of cooling the liquid;
   d) Temperature sensor;
   e) Sensor of provision of a valve of butterfly (TPS);
   f) O sensor of absolute pressure in the oil pipeline (MARCH);
   g) O oxygen sensor (and the sensor of secondary oxygen in models with the motor D16Y7);
   h) Sensor of the EGR (D16Y5) valve;
   i) Valve VTEC eletromagnética (D16Y5 and D16Y8);
   j) Switch of sensor of pressure of VTEC (D16Y5 and D16Y8);
   k) A valve of the stabilization of turns of wasting time (IAC).
10. There supports the motor a monkey (for aims of the distribution of the load between a head of a monkey and the trundle bed of a case put the wooden grindstone). Withdraw an arm of the superior support of the motor (to see the Check of a state and the substitution of the support of a support of the triangular form of interruption of the unity of power).
11. Withdraw the support of the triangular form of meeting that supports the oil pipeline of entry and result pins of a flange of a final collector.

To the will the oil pipeline of entry and / or a final collector they can separate of the motor (to see the Removal and the installation of the oil pipeline of entry and Removal and the installation of a final collector) making easy new handlings with a head.

12. Discover a head of cylinders (to see the Removal and the installation of a covering of a head of cylinders).
13. Remove the distributor of ignition (to see the Chief Elektrooborudovaniye of the motor) together with a covering and wires joined him by VV.
14. There takes away a belt of GRM drive (to see Removal, checks of a state and installation of a belt that distributes the gas and cog-wheels of GRM drive), the meeting of yokes (to see the Removal, the check of a state and the installation of the meeting of yokes) and the axle (to see the Removal, the check of a state and the installation of the axle).
15. Working as must be, the return shown in an illustration (see down), in stages (in turns of 1/4 of the approximation) it weakens pins of the fixation of a head so that the possibility of his reversion manually appeared. Try to be remembered an agreement of each one of fixing pins – in the meeting they have to be screwed strictly at ancient places.
16. Withdraw a head of cylinders of the motor. If the head is not separated of the block, it is possible to use the lever that must be begun between an arm of the bomb of direction and the block (do not hook a chief up below the inter-connected surface in absolute). Put the retired head of the motor in the couple of wooden blocks to avoid the damage of surfaces of in favor freemasonry.
17. The proceedings description of desmontagem of a head and check of a condition of his component internal supplies with itself in the Part the General repairs and the repairs of capital of the motor of the present Chapter. In this stage only they appreciate planeness of the inter-connected surface.

Installation

ORDER OF REALIZATION

1. The inter-connected surfaces of a head and the cylinder block will be absolutely pure and dry.
2. Carefully smooth the inter-connected surfaces of a head and the cylinder block. To scratch out to remain of the material builds placing and deposits from coal, rubs surfaces with the rags moistened in the acetone. The existence in the inter-connected surfaces of the material of the old placing in the moment of the installation can bring to the violation of the tension of the landing of the placing and, consequently, the development of holes. Prosecuting the block, zakuporta of an opening of rags of cylinders in order that avoiding the blow in them small garbage and several foreign objects (like last resource, carefully inhale cylinders). Like the head and the cylinder block they are done from league from gentle aluminum, I tie with the extra care, trying not to leave in the inter-connected scratches surfaces and zadir (use instruments only of brass or plastics to clear of deposits).
3. Check the inter-connected surfaces of a head and the block of the existence of deep scratches, zadir and other damages. The easy defects can be removed through a paper of emery of fine granulation. In more serious cases the only alternative is the in favor point of component ones.
4. A faucet of the convenient size banishes openings of woodcarving below pins of the fixation of a head. Pins in series insist on a vice of a head, walk in his woodcarving lerky. The existence in circles of a woodcarving of old man selante, dirt and products of the corrosion it turns in the discrepancy of the true effort of the indications corset themselves of the fixation of indicative of key of dynamometer.
5. Put in the cylinder block the new placing of fighter (the marking of the type of TORAHS). It wets with selante of edge of a covering of a belt that distributes the gas inter-connected to the block. Exactly install a head of cylinders in the block.

6. Polish a woodcarving and the lowest surface of leaders of fixation of pins with oil of pure reason and fixation of screw at the ancient places. To work in that order (companion to see an illustration), in four receptions holds tight pins of the fixation of a head of cylinders with the necessary effort (to see Specifications). In view of criticality of the pins objective, the authors of the present manual recommend to observe the next measures for precaution in the moment of his pressure:
a) O use of the developed effort of a key of dynamometer provided with the walk of catraca with the limitador it is preferable. Otherwise act extremely exactly, trying not to take off a thread incidentemente.
b) If in a vvorachivaniye it begins the pin doing some sound (scream, scratch, clicks, etc.), completely it result and repeated attempt.

7. An axle pin puts a cog-wheel, soon establish a belt that distributes the gas (to see Removal, checks of a state and installation of a belt that distributes the gas and cog-wheels of GRM drive).
8. The installation of the remained component ones is done as it must be, the return to an order of his be demolished.
9. Manually slowly become an end of inclination in reverse sense to the movement of the pointers of the clock in two whole revolutions.

If in a provorachivaniye of an end there is resistance, immediately it gives birth to avoid the damage of valves in his contact with the pistons bottoms.

10. The motor begins and check the fairness of the installation of a corner of an advancement of the ignition (to see the Front Regular maintenance).
11. Heat the motor up to the temperature of normal work and it is checked by the existence of signs of holes. One secures of the usefulness of the functioning of the motor.
