In fact, every car owner, sooner or later, produces motor overhaul. In principle, there is no accurate period of time, after which it is necessary to make a major overhaul of the engine. Many motorists believe that the overhaul should be made if the mileage of the vehicle is large enough. However, it is not. The need for this procedure may occur by car with a rather small mileage. It all depends on the manner of your ride and on how often and qualitatively you care for the engine of your vehicle.

Motor care, driver actions to extend the "life" of the motor

To extend the life of the motor, it is necessary to create for it the most gentle operating conditions for it, try to stick to the optimal turnover of the motor operation and use only the technical fluid recommended by the manufacturer, in particular, high-quality oil and fuel.

In addition, regularly spend various preventive measures and do not forget to carefully take care of your car.

Only in this case, he will serve you as long as possible.

Overhaul, which indicates the need for motor overhaul

The fact that the engine of your vehicle needs overhaul, you can tell you the details of the cylinders. This is noticeable for a stronger vehicle needs - consumption is more than one liter per thousand kilometers.

An explicit sign of a motor disorder is the presence of a characteristic siza smoke from the exhaust pipe. However, when these symptoms appear, it is not necessary to hastily draw conclusions.

For example, a large oil consumption may indicate the loss of its elasticity of oil-challenged caps.

The crank-connecting mechanism should be selected - a characteristic knock is possible, which speaks of complex damage to bearings, crankshaft liners and other components of sliding. You can diagnose the knock using a stethoscope, and the pressure in the cylinders will help determine the pressure gauge. Serious signs for the fact that in the near future the motor major repairs will be required, such symptoms can serve - lift the fuel consumption, power loss, the increase in the noise of the engine.

If you have found the main number of the signs listed above, then, most likely, you cannot avoid "Capitals". However, for more accurate conviction, the engine overhaul is required or not, it is better to turn to a special service station, where the degree of wear of all elements of the motor will be checked. With this test, the stations use special devices - nutromers, arrogant indicators, micrometers, measuring brackets. With the help of these devices, you can accurately determine the needs of the motor in repair.

Trust professionals, or do repair with your own hands

Many drivers think that the motor overhaul of the motor is independently much cheaper than contacting specialists for a hundred. However, this is not always the right statement. For example, in some situations, it is necessary to flush and bring the cylinder mirrors or replacing the piston rings. To conduct such operations at home is very hard. In addition, it is necessary to have special devices, which, as a rule, are quite expensive. Therefore, in this case, it is advisable to resort to the help of professionals.

In addition, at maintenance stations, under the overhaul, the starter, Gernoant and the distributor of your vehicle are carried out. If they are faulty, they will be replaced.

Engine overhame spare parts

For the overhaul of the motor, you will need the following spare parts:

1. Water pump.
2. Oil pump.
3. Fuel pump.
4. Guide sleeves and valves.
5. Sets of gaskets and seals.
6. Star.
7. Piston rings.
8. Insert bushings.
9. Chain.
10. Belts.

And this is not a complete list of all the details that you will need.

It is advisable to start to disassemble the motor and pay attention to the elements that require a replacement. And only after that deal with the acquisition of the necessary spare parts. If you decide to contact the car service, then after the diagnosis, the specialists will tell you which elements need to be purchased for subsequent replacement.

Assistant tools

To accurately determine the need for internal combustion motor overhaul, you will need such tools:

1. Compressometer.
2. Endoscope.
3. Nutrometer.
4. Manometer.
5. Stethoscope.

Engine disassembly, repair and diagnostics manual, step-by-step instructions

There is no standard instruction, how to produce overhaul engine. It all depends on a certain brand and model of your vehicle and from the wear of the radio nodes of the motor.

In any case, for overhaul, it is necessary to fully disassemble the engine. The process of this lengthy and time-consuming, which is not always possible to produce at home.

For those who are not terrible difficulties, we have prepared a brief guide on the motor overhaul:

1. To begin with, carrying a motor from the vehicle. What would the engine of your car become a little easier, you need to dismantle some units - start from the carburetor, then remove the cylinder head cover, dismantle the generator, disconnect the gearbox, dismantling the collector, after which we remove the flywheel and grip. Now you can unscrew the pillows and remove the engine.
2. To gain access to the crankshaft and pistons, you need to remove the crankcase cover. Then unscrew the connecting rods. Take out the pistons and remove your fingers from them. Now you need to remove the crankshaft and its liners.
3. Pay special attention to the wear of the sleeve and crankshaft neck. If necessary, spread them. In addition, do not forget to buy rings for pistons, fingers and new inserts.

Engine assembly, step-by-step instruction

Motor assembly involves the following actions:

1. Start follows from the moment on which the disassembly of the motor has been finished. Before installing the crankshaft, it is necessary to replace old liners and carefully treat new oil. Do not confuse them.
2. Then you need to heat into the rod oil and gently insert new fingers into the pistons. Next, we wear new rings - the first thing we wear the oilmaging ring, after which the second compression, then the first compression. Turning the rings should be as cautiously as possible to not damage them. With special caution, dress the second compression ring, because it is made of cast iron.
3. Now we install ready-made pistons in the cylinder block. For this you need a mandrel. If you do not have it, you can make a mandrel with your own hands. To do this, take a tin strip to wrap the head of the piston and hold the mandrel with the passats. After that, correct the optimal position of the connecting rod and slowly mount the piston in place.
4. Carther's cover We return to the place and install the motor into the vehicle. We twist the pillows, put the flywheel and clutch, mount the gearbox. Return the collector, the cylinder block cover, the generator and the carburetor.
5. Scroll through the crankshaft several times and, if the battery is fully charged, we run the motor.

Engine running, professionals

It is not necessary after repair to expose the vehicle with high loads. First you need to warm up the motor. Then launch the engine and let it work at idle about ten minutes. After that, the motor must be turned off and cool. These manipulations should be done several times. Now the motor should work at idle about ten o'clock. Only after the above operations you can begin the operation of the vehicle.

The first fifty kilometers of driving should not overclock the vehicle more than forty kilometers per hour. Next, it can be dispersed to 60 km / hour. Then, every one hundred kilometers of driving, it is necessary to increase the speed of the car by 10 km / hour. Pay attention to the level of compression level. If it is absent, send a vehicle to re-diagnostics. Try not sharply accelerate and do not slow down.
