A vital element of the functioning of any technical unit is a permanent lubricant of parts. If the oil in insufficient quantity goes on the driving parts of the car, it entails the so-called oil starvation. The elements appear jacies, the engine undergoes constant overheating, the wear of parts accelerates and so on. Ultimately, such consequences lead to the engine breakdown, which promises costly and complex repairs.

Purpose of oil pump

The oil pump is playing an important role in the functioning of the car, namely the lubricant of the engine parts. It pumps oil from the Carter by oil canals, lubricating rubbing elements. Accordingly, the serviceability of this important element is extremely necessary, but the breakdowns occur.

Where is the oil pump

Oil pump is located inside the crankcase. With the help of two fasteners, it is attached to the cylinder block.

Symptoms breakdown oil pump

The first sign of the oil pump breakage is a lit lamp on the dashboard. In this case, check the oil pressure in the system and pay attention to its flow, since the yield of the oil pump is characterized by a decrease in pressure in the oil supply system and a noticeable increase in its flow.

Causes of the oil pump breakage

The first and most common cause of the breakdown of the oil pump is a scored oil worker, as a result of a clogged crankcase. If this kind is faults, it is recommended to drain the oil, dismantle the pallet, then rinse it together with the oil worker. Since the oil filter stands after the pump, through an oil worker and some other parts undergoes the right-filtered lubricant, which increases the likelihood of oil pollution, as well as wear details.

Another frequent breakage of the oil pump is damage or breakage of the housing of the node or its gears. The result of such damage becomes an increase in the gap between the details. Theoretically is the possibility of replacing the oil pump housing or the manufacture of staining with further fitting, but this process is not cheap and quite laborious. Therefore, often at first symptoms of the oil pump malfunction, worn items immediately change.

Causes of oil pump damage:

1. The level of oil in the crankcase is constantly low.
2. Course of devices that are responsible for pressure control.
3. The use of poor-quality oil with inappropriate viscosity.
4. Mixed oil and coolant.
5. Pollution of the oil pump fence.
6. Pollution of oil filter components.
7. Failure of safety or lubricant valves.

Checking the oil pump

As you know, there is a sensor on the car instrument panel, showing the oil pressure level. If, when the motor is running, this warning lamp lights up, it means you need to urgently stop the operation of the power unit and perform diagnostics, because there is a risk of rapid wear of the system and the subsequent motor failure.

To independently check the oil pump, open the hood and see if there is fresh oil oils on the engine; In the absence of "crankcase protection", see if there is damage on it. If there is still a flow on the crankcase, it is necessary using a piece of rubber, rags or tape to temporarily take it up to the nearest one hundred.

Next, check the oil level in the engine and the result. If the lamp does not burn, you need to replace the crankcase. If continues to flash, go to the nearest service station to find out the reason. In addition, if when checking, you hear the sound of the gear, this also indicates the wear of the oil pump and the need for its repair.

Oil pump repair tools

For repair of the oil pump, span keys, soldering iron, pliers and a shock screwdriver are used. It is also recommended to use special technical means containing oil, as well as superficially active substances when cleaning elements of oil pump. These funds do not pollute the surface and are not aggressive.

After applying these funds, there is no need to wash the item, as they have properties that create on the surface of the detail protection against the effect of air on the metal. It should be noted that the repair of the Maslonasos is a delicate matter that requires a concentration of attention, so good lighting will also be required for proper diagnostics.

Disassembly, visual diagnostics of parts and repair of the oil pump

Oil pump is installed near the engine, since it is an element. First, remove it from the motor, for which it is necessary to drain the oil, unscrew the oil crankcase of the engine and remove the oil pump with an oil truck.

Order of work:

1. Using the drum screwdriver, unscrew the screws of the oil pump cover.
2. Remove the oil pump cover and carefully clean the parts from oil sediments and pollution with a napkin.
   
3. Take a caliper or a special line and measure the distance between the pump housing and the output rotor. The optimal distance should be no more than 0.400-0.483 millimeters, with other results of the oil pump will not be tightened to the required pressure, and it will be necessary to replace it.
4. Also measure the side gap of the internal rotor. Maslonasos needs to be replaced if the side gap is more than 0.03-0.085 millimeters.

   

5. Clean the cork of the reduction valve. Under it there are springs and gum. Rubber must be replaced. The spring should be measured in a calm state, its length should be 81 millimeters. If there are deviations, the spring also changes to a new one.
   
6. We also remove the reducing valve. Easily knock on a clean rubber or wooden surface. If the valve does not want to go out, it should be carefully pushing it with a forceps or toothpick.
   
7. Inspect all recoverable parts, as well as body parts for signs of wear.
   
8. Measure the thickness of the slave and the drive gear. The thickness of the slave must be at least 7.35 millimeters, and the leading is 7.42 millimeters. If the thickness is less, change the item.
   
9. Also check the axial gaps of gears. We install the driven gear into the housing, after which the metal line measure the gap between the gear and ruler. In the same way, check the lead gear. The axial clearance for the driven gear should be 0.15 millimeters, for the lead - 0.12 millimeters.
   
10. Inspect the reducing valve for damage, traffic jams and oil pollution. If they are missing, clean all the holes and collect the oil pump in the reverse order using the sealant.
    

Maslonasosa Replacement Tools

To replace the oil pump, you will need: cardan hinge, spanners of various diameters, end heads and extension cord.

Replacing the oil pump, step-by-step instruction

Order of work:

1. Drain the motor oil.
2. Remove the crankshaft gear pulley, for which it is necessary to remove the pulses of the generator and timing pulleys, aligning the tags. It should be noted that the process of setting the marks from different car models is different, so you should read the leadership to your car.
   
3. Next, remove the pallet of the crankcase.
   
4. Unscrew the fastener of the oil worker and remove the oil worker.
   
5. Unscrew the six fastening bolts of the oil pump using an overhead head and extension.
   
6. Between the pump and the indigenous bearing insert a screwdriver, slightly shifted, and then remove it.
   
7. We carry out the replacement of the oil pump.
8. Align the lead gear with lys on the crankshaft.
   
9. Lubricate the edge of the crankshaft of the motor oil.
10. Set the new oil pump on the crankshaft. Tighten six fastening bolts to attach the olon pump to the cylinder block.

The advice of the pro, which can lead to the untimely replacement of the oil pump

In mandatory, check the serviceability of the oil pump. The late replacement leads to undesirable consequences. More expensive elements can be released, and even the engine itself. For a power unit function for a long time and without problems, it is necessary to replace the oil and oil pump on time.
