Automotive Turbine Malfunctions

Automotive Turbine Malfunctions

An automobile turbocharger, despite the longevity (10 years) and wear resistance promised by the manufacturer, still fails, jumps and breaks. Therefore, it is necessary from time to time to eliminate malfunctions of the turbine of both diesel and gasoline engines. And in order to identify the signs of a malfunction in time, you must always pay attention to the non-standard behavior of the car.

The turbine has broken down if:

  • there is a feeling that traction has disappeared (power has decreased);
  • when accelerating a car, smoke of blue, black, white comes out of the exhaust pipe;
  • when the engine is running, whistling, noise, grinding are heard;
  • consumption has increased sharply or there is an oil leak;
  • air and oil pressure drops frequently.
  • If such symptoms appear, then in these cases a thorough check of the diesel turbine is needed.

Signs and malfunctions of the turbocharger

  • Blue exhaust smoke is a sign of combustion of oil in the engine cylinders that got there from the turbocharger or engine. Black indicates an air leak, and white exhaust indicates a clogged turbocharger oil drain.
  • The cause of the whistle is an air leak at the junction of the compressor and motor outlet, and the screeching indicates rubbing elements of the entire turbocharging system.
  • It is also worth checking all the elements of the turbine on the engine if it shuts down or stops working altogether.

90% of automotive turbine problems are oil related.

Lack and low oil pressure

Occurs due to leakage or pinching of oil hoses, as well as due to their incorrect installation to the turbine. It leads to increased wear of rings, shaft journals, insufficient lubrication and overheating of the turbine radial bearings. They will have to be changed.

5 seconds of operation of the turbine of a diesel engine without oil can cause irreparable damage to the entire unit.

Oil contamination

It happens due to the untimely replacement of an old oil or filter, the ingress of water or fuel into the lubricant, the use of low-quality oil. Leads to bearing wear, blockage of oil passages, axle damage. Defective parts should be replaced with new ones. Thick oil also harms bearings, as it builds up deposits and reduces the tightness of the turbine.

Entry of a foreign object into the turbocharger

Leads to damage to the compressor wheel blades (hence the air pressure drops); turbine wheel blades; rotor. On the compressor side, replace the filter and check the intake tract for leaks. On the turbine side, it is worth replacing the shaft and checking the intake manifold.

Can I repair a turbine myself?

The turbocharger seems simple and straightforward. And all you need to repair a turbine is to know the turbine model, engine number and manufacturer, and have spare parts or a factory turbo repair kit on hand.

You can independently carry out visual diagnostics of the turbocharger, dismantle it, disassemble and replace defective turbine elements, and reinstall it. Inspect the air, fuel, cooling and oil systems with which the turbine closely interacts, check their operation.

Turbine breakdown prevention

Change the air filters promptly.

  1. Fill with original oil and quality fuel.
  2. Completely change the oil in the turbocharging system after every 7,000 km.
  3. Observe the amount of boost pressure.
  4. Be sure to warm up a vehicle with a diesel engine and turbocharger.
  5. After a long drive, allow the hot engine to cool down by idling for at least 3 minutes before turning it off. There will be no carbon deposits that damage the bearings.
  6. Perform regular diagnostics and take care of professional service.
Electrical Equipment of the Tractor

Electrical Equipment of the Tractor

Electrical equipment is one of the main tractor systems, along with the others, requiring timely and high-quality maintenance. This means that the maintenance of the tractor electrical equipment requires deeper knowledge and higher qualifications of the operating personnel.

Practice shows that, firstly, the maintenance personnel not only pays insufficient attention to the study of the electrical equipment of the tractor, but is generally negligent in the operation.
Ignorance, combined with excessive enthusiasm, has become a scourge of our service departments. At the slightest failure of the tractor’s electrical equipment in operation, the operators, without even looking at the diagram given in the manual, without trying to figure it out, begin to carry out work on diagnosing and restoring the system from the most difficult. They disassemble the starter, the relay unit, thereby destroying the key components of the electrical equipment. And in most cases, the cause of problems is an elementary failure to comply with the rules of maintenance.

Troubleshooting

Repair of electrical equipment should be carried out only after a thorough study of the operating and maintenance instructions for a particular tractor system. It should be remembered that basically all possible electrical equipmentmalfunctions occur for the following reasons:

  • failure of the end consumer (lamp, signal, traction relay, etc.);
  • lack of contact where it is required (lack of “ground” of the device, corrosion of the power circuit contacts, wire breakage);
  • the presence of a contact where it should not be (short circuit to ground, which is most often signaled by a blown fuse);
  • oxidation caused by voltage drop and intense heating of broken contacts;
  • burning of contacts in the starter traction relay;
  • failure of contacts of switches.

To prevent wasting time on troubleshooting, it is necessary to carry out diagnostics according to a logical scheme. It is best to use a test lamp or tester (ohmmeter and voltmeter) to test the electrical equipment. Use a lamp with a power of at least 20 W (lamp A12-21) as a control lamp.

Typical electrical equipment malfunctions and methods of their elimination

It is necessary:

  • check the contacts at the place where the wires are connected to the battery elements;
  • check the serviceability of fuse F1 installed on the engine under the tractor hood;
  • check the serviceability of the circuit leading from the battery to the fuse.

There is no charging after starting the diesel.

It is necessary:

  • check the condition of the alternator drive belt and tension adjustment;
  • check the function of fuse F1;
  • using the voltage indicator, check the value of the regulated voltage of the generator, which should be equal to 13.2-14.1 V in the “Summer” position of the seasonal adjustment screw or 14.2-15.2 V in the “Winter” position;
  • check the reliability of contacts in the circuit leading from the generator to the voltage indicator. The check should be carried out at rated engine speed and working headlights on.

The battery is systematically undercharged.

It is necessary:

  • check the value of the regulated voltage and, if it is below the permissible, set the screw for seasonal adjustment of the generator to the “Winter” position or replace the IRN (integral voltage regulator);
  • check the technical condition of the battery;
  • check the reliability of the terminals of the terminals of the wires leading from the generator to the battery, excluding the possibility of resistance caused by poor contact or oxidation.

The starter motor develops a low cranking speed.

It is necessary:

  • a) eliminate possible loosening or oxidation of the power circuit terminals:
  • on rechargeable batteries;
  • on switching off the “mass”, including the screws securing the switch;
  • “mass” jumper between the cab and the tractor body;
  • on the terminals of the starter and its mount;
  • b) check the state of charge of the storage batteries.

The traction relay of the starter is activated (a knock is heard to turn it on), but the diesel engine does not rotate with the starter. In this case, the indicator lamp on the instrument panel of the tractor functions normally or dies out.

It is necessary:

  • check and, if necessary, clean the contacts of the starter traction relay, and also adjust the drive mechanism;
  • check the condition of the starter brush-collector assembly.
Diesel Fuel System

The First Signs of a Malfunction of the Diesel Fuel System

Serviceable and well-adjusted fuel equipment ensures the supply of finely atomized fuel in equal portions and at a certain time to the combustion chambers of all cylinders. Fuel must be supplied in such an amount that is necessary to obtain the required engine power at a given crankshaft speed. Failure to comply with these requirements leads to excessive fuel consumption, reduced power and diesel engine service life.

When operating a diesel engine, malfunctions may occur in the power system, the main symptoms of which are:

  1. Increased fuel consumption.
  2. Unstable engine idling.
  3. The engine is not picking up speed.
  4. It is difficult to start the engine in cold weather.
  5. The car started to smoke (black, blue, white-gray smoke from the exhaust pipe).
  6. Loss of engine power.
  7. When the engine is loaded, a characteristic sound (crackling) is heard.

Malfunctions in the power supply system occur due to failures and damage to devices and fuel lines in the low and high pressure lines. The main faults in the low pressure line include leaks or clogging of fuel lines and filters, as well as malfunctioning of the low pressure pump, which leads to insufficient fuel supply to the high pressure pump.

Malfunctions in the high pressure line are reduced to malfunctions of the high pressure pump and injectors. They most often cause difficult engine start, interruptions and uneven operation of the cylinders, loss of engine power, increased smoke of the exhaust gases, refusals to control the crankshaft speed.

Leakage of the low pressure line occurs, as a rule, due to leaks in the connections. If such leaks appear in the line between the fuel tank and the low-pressure pump, then the fuel supply decreases sharply, the engine runs unstably at a low crankshaft speed and stops when the load increases.

When assembling the lines, complete tightness is achieved, especially at the connections to the fuel tank, coarse filter and low pressure pump.
Clogged fuel lines and filters in the low pressure line. The degree of clogging is judged by the decrease in fuel pressure in the line at the inlet to the high-pressure pump. Determine the value of the pressure on the control pressure gauge, which is connected to the hole for the plug to release air on the fine filter. If the pressure is below the permissible limit with tight connections, then replace the filter elements and check the operation of the low pressure booster pump.

Low pressure pump malfunctions cause a drop in pump performance and affect engine starting and operation. First of all, it becomes difficult to start the engine, since at a low crankshaft speed, the pump will supply less fuel even at a lower pressure. In the event of an increase in the load and at a low fuel supply by the pump, interruptions in the operation of the engine are observed and it will not be able to perceive the load.

The main causes of malfunctions and malfunctions of low pressure pumps are: debris and dirt under the valves, breakage or loss of spring elasticity, piston hanging, wear of the pusher rod. With increased wear of the main working surfaces of the pump (piston and cylinder), its performance decreases and the pressure in the line drops. A decrease in productivity can also occur when the elasticity of the working spring decreases.
Malfunctions of the high-pressure pump and injectors during operation can only be partially detected, most of them are determined only when checked using special equipment. Below are the main symptoms and nature of high pressure pumps and nozzles.

Difficulty starting the engine occurs due to wear of plungers, liners and pump discharge sections, breakage of plunger springs, discharge valves, lowering of injection pressure by injectors as a result of loss of elasticity of rod springs, development of nozzle openings of nozzles and violation of optimal pump adjustment.

Increased opacity of exhaust gases is observed with excessive fuel supply by the high-pressure pump sections, violation of the injection advance angle, decrease in the opening pressure of the injectors, jamming of the needle and increase in the nozzle openings of the injectors. In these faults, the exhaust gases are black.

Tractor Transmission Diagnostics

Tractor Transmission Diagnostics

Tractor transmission is a set of devices that connect the engine to the drive wheels or planetary gears. The performance and performance of special equipment depend on the serviceability of this system. To extend the service life of the transmission, it is important to carry out timely maintenance, check its components and mechanisms. Diagnostics of the tractor transmission provides for an assessment of the condition of the gearbox, main and final drives, and other elements, on the basis of which conclusions are drawn about the possibility of subsequent operation of the units, the need for repair or replacement of components.

The specialists of our field team provide services for assessing the condition of stepped, continuously variable and combined transmissions of tracked and wheeled tractors of any model. We work promptly thanks to the presence of a large number of service vehicles and qualified diagnosticians, we have all the necessary tools to accurately identify all existing problems and their causes.By contacting us, you can save time and money on the transportation of special equipment to the service station, since we carry out work on the basis of the client. Upon completion, you will be provided with a detailed report on the condition of the transmission as a whole and its individual parts, recommendations for performing maintenance and troubleshooting are given.

What work is carried out when diagnosing the tractor transmission?

During the work, the degree of wear of bearings, gear teeth, unit housings, gear forks, shafts is assessed. Masters measure the total angular clearance and, if the permissible value is exceeded, they conduct a deeper check to find the cause of the malfunction.

The performance and service life of the transmission components largely depend on the correct functioning of the clutch. Due to the wear of the friction lining of the discs, the clutch begins to slip, as a result of which the working surfaces heat up, the elasticity of the pressure springs decreases, the gear teeth and the gearbox spline joints fail prematurely. Therefore, special attention is paid to checking the condition of the clutch.

The most important element of the tractor transmission is the cardan shaft, according to statistics, breaks down quite often. Its malfunction is indicated by knocking when the gearbox is turned on, uncharacteristic noises while driving. Diagnosticians, using special scanners, will determine the cause of the breakdown and give recommendations for repair. Minor malfunctions may require replacing the hinges, tightening the mounting bolts, or simply cleaning the shaft from dirt. In the event of a serious breakdown, the propeller shaft may need to be replaced.
