Q:From where on the car can you see that the oil pump is not oiled?

Hello, not on the oil, then 1 valve sound than normal, 2, open the oil cap to see, 3, the best way is conditional removal of oil sensors, get off to see

Q:What are the problems caused by engine oil pump damage?

The damage to the diesel engine oil pump will cause the following problems and solutions:(1) the oil inlet and outlet pipe of the oil pump is leaking at the joint, the oil pump stops supplying oil, and the inlet and outlet pipe gaskets are replaced, and the sealing surface is tightly sealed.(2) oil pump, check valve and seat surface wear or damage, failure, the oil pump does not supply oil, grinding, check valve seat surface or replace the check valve.(3) the oil pump piston wear and seal failure, the oil pump to stop oil supply, replace the piston treatment.(4) the oil pump piston spring is broken, the oil pump fails, the piston pump oil function is stopped, the oil pump is not supplied, the piston is replaced and the piston is taken off.(5) the oil seal of the piston rod of the oil pump is damaged, which causes the diesel oil to enter the injection pump cam chamber, and makes the engine oil of the diesel engine bottom oil become thinner. At this point, the oil seal of the top rod should be replaced.

Q:The function of the oil pump screen is troublesome

His main function is to filter the impurities in the oil (including the impurities in the oil itself and the impurities in the lubrication process)

Q:4Y engine oil pump, okay? Still lifting the engine?

You don't need to lift the engine, but the 4Y engines are usually chain. You need to make the timing right.

Q:Today to Hafei repair station, because before going to the maintenance when the master told me that the chain is loose, the first open, what you feel the big voice to change the chain, opened the time I feel the start and to the oil when the sound is big, go to repair. In the afternoon, the master checked and told me that the oil pump didn't supply oil, and said that the chain and the oil pump were together, and the cost would be about 1500 yuan. Not very clear, want to consult a master, this chain will always loose it? What are the symptoms of the car, there is a problem with the oil pump, the problem of the car, the master said repair, then repair, because I do not understand, do not want to bad, halfway do not know how to get. StopI asked other people again, and they said they wouldn't have that much money, and it should be a small problem. But the maintenance station people say very seriously, is it really fooled?!

The master fooled youThe oil pump chain is usually tensioned and tight, and if the chain is loose, it will not cause the oil pump to not supply oil.Moreover, the drive chain on the engine is generally maintenance free for life, unless there are very few cases.If the oil pump is not oiled, the oil pressure switch on the engine will alarmFirst make sure where the sound is, and if the chain is loose, adjust or change the tensioner

Q:Sonata 6 cylinder morning taxi dadada big sound like the Volkswagen B5 engine chain expansion broken chain to the valve cover sound, car temperature reached 90 is not loud, and a high speed with the speed of 120 continuous driving not more than 20 kilometers, over 20 kilometers, more like a car with no oil if the valve is inside the chaos ring, and three cylinder ring, the outside does not ring, beg you master to solve!

Cold car is a normal phenomenon. Please feel free to use it.

Q:How do I see the motorcycle's oil pump is broken? Two red

Hello, friend. First of all, tell you that the two stroke motorcycle does not have an oil pump. If it's a four stroke. In 70, 90100 of the three models you can put the screws on the cylinder head of the lower right to loosen the. Then start the locomotive. If there is oil to the outside, then that the normal oil pump. If not, check the oil pump wheel for wear first. Because the oil pump wheel wear, even if the oil pump is not bad. It doesn't work either. The three models are identical in structure. Their oil pumps and pump wheels are relatively easy to break. Another 125 models, men's and women's pedals. Men's words a screw is loosen cylinder head top, then start. Organic oil emits just normal. No oil smoke, also want to look at the screen is not blocked. The screws on the ladies pedal are the same as the 7090100

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:What parts of motorcycle oil pump are connected with them?

It is connected with the engine crankshaft by the helical gear, turbine spiral rod combination, small chain and so on, and works simultaneously with the engine crankshaft

Q:Engine oil pump is blocked when the chain would ring

Sure. Bad lubrication.
