Q:Do you need to disassemble the chain for replacing the oil pump of TOYOTA corolla?

Hello, timing chain is generally no need to disassemble, you need to remove the oil pan, the oil pump may also have a chain

Q:My car: Chery QiyunTransmission: ManualDisplacement: 1.6 litersMileage: 7 kmPurchase time: September 2002Problem Description: I have a Chery and because I did not pay attention to a few kilometers from the later results cannot flameout repair factory towed to overhaul the results I said no money for a ZWZ the sound of the engine also can now open half machine oil flash engine temperature is very high the garage man said no pressure oil pump is not up to actually change a replacement pump not expensive I fear the garage man pit I would like to ask the people I now understand the point of repair is not for the engine oil pump can be changed ZWZ will soon appear problem solving and my score how to add light fuel oil or not hundreds of state awayBut the overhaul of thousands of car also cannot be worth a few money is not for the oil pump or no repair as the repair factory is the largest side this boss said that one hundred percent is the pump problem for good

Lack of oil can be a big problem, the oil pump oil may be bad, do not equal to the lack of oil, ZWZ change can not solve the fundamental problem. Find a professional repair shop in a fix, may have to overhaul it, otherwise the money; the fuel lamp may be allowed, indicating instrument is broken, oil is more likely to float the mailbox (fuel level sensor, professional name can't remember) bad, a replacement is good, this is not expensive, replacement your working hours. Feigui.

Q:The new car oil pump for three months is out of order. May I ask for a new car?

Yes, you can replace it or replace the oil pump

Q:Are the engines all organic?

There are some motorcycle engines without oil pumps, which are "splash lubrication"".

Q:What is the effect of excessive oil on the oil pump?

The oil pump doesn't work, but it has an impact on the engine. It makes the engine weak and has a lot of carbon for a long time. Don't ask how I know it. It's still in the car.

Q:I am CB ZS200 recently found the engine abnormal sound their tune at the small valve clearance chain are good but there are still abnormal sound so doubt is not a problem of lubricating oil pump is not good for cam friction sound is that the machine in 2 years ago has changed because the oil pump oil pump cam is caused by the blockage ask the master how to identify whether or not the work

Start the engine first and see if there's any white smoke

Q:How do you install the pedal motor pump?

Put the unit on the foundation with anchor bolts, between the base and the base, and use a pair of wedge pads.Release the axle shaft and place on the pump shaft and base with a level gauge. Adjust the level of the machine by adjusting the wedge pad and tighten the anchor bolts properly so as not to move around.Correct the concentricity of the pump shaft and the motor shaft, and allow the deviation of 0.1 mm on the outer circle of the axle shaft; two the clearance of the coupling plane shall be guaranteed 2~4 mm, and the clearance shall be uniform, and the tolerance shall be 0.3 millimeters.After connecting the pipeline and determining the direction of the motor rotation, then coupled with the coupling, and then check the concentricity of the shaft.In the actual test run 2~3 hours after the unit, for final inspection, if there is no adverse phenomenon, that the installation of qualified. Check the temperature and vibration of the bearing during the test run.During installation, all holes in the unit shall be covered to prevent debris from falling into the machine.In order to prevent the sundries from entering the pump, the filter shall be installed on the newly installed pipeline. The effective cross section shall be 2-3 times larger than the cross section of the suction pipe.However, the oil pump rarely fails, generally as long as the opening of the cylinder head, see more fresh oil or start the engine, there is oil jet, indicating the normal operation of the oil pump.

Q:The car oil pump is broken. What are the problems?

If you lose the oil pressure, the alarm light will go on, and continue driving will cause fatal harm to the engine.Adjustment of oil pressureThe oil pump is classified by the steady discharge of the pump, which means that the maximum pressure must be limited by the relief valve. If the pressure relief valve is not used, the system pressure will rise to a dangerous level, which may cause the engine to be damaged.The oil pressure reducing valve is composed of a valve or a ball and a coil spring. The oil is sucked in the strainer and sent to the oil filter. When the fuel supply pressure increases with the engine speed, the pressure relief valve opens. At this point, the oil enters the inlet side by way of the bypass from the exit side to maintain the specified pressure. Since the stiffness of the spring used on the pressure reducing valve is very accurate, the maximum pressure of the oil pump can be guaranteed. If the stiffness of the spring increases, the oil pressure will increase. But the pump will not increase the amount of oil discharge.In addition, the following factors affect engine oil pressure:1. the speed of the oil pump, the oil pressure increases with the speed increase;2., the viscosity of oil, the greater the viscosity of oil, the higher the oil pressure;3. oil gap, bearing clearance will hinder the oil pump boost. When the bearings wear, it is difficult to form the appropriate pressure.

Q:What about the oil quality of automobile engine oil pump?

Take the pressure gauge to measure the pressure

Q:What is the function of the oil pump?

The oil pump is used to press the oil in the oil pan to the filter, and the engine oil can still be reliably conveyed to the friction surfaces of each lubricating oil passage and the moving parts after the filter is passed. When the engine is working, the oil pump keeps working to keep the oil circulating in the oil circuit. If damaged, there may be noise, noise, power attenuation, if not in time, even the cylinder can not start, the engine completely scrapped!
