Motor bearings are generally broken, abnormal! If the motor drives the oil pump to work abnormally, then check the bearing of the oil pump or the connecting gear of the motor and the oil pump, whether the gear is intact or not! If the current voice is not expected so but now xigangpian motor inside some manufacturers is a complete xigangpian some manufacturers of the motor is zero material splicing have all kinds of information have a contact number
Q:What part does the electromagnetic valve connect to?
The external solenoid valve is installed on the oil pump, and the oil pump solenoid valve is used to realize the oil pump two or multistage oil pump pressure, and is in the oil pan, but the position is the external of the engine.Built in solenoid valve installed in the oil pump, usually in the main oil road and oil pump, controlled by ECU, installation position in the cylinder.
Q:SUZUKI motorcycle oil pump is not on the oil, the circuit is not blocked, to replace the oil pump
Is the oil filter and the oil filter plugged? Is the filter core apron missing? How do you make sure there's no blockage? No reason for the oil is only the oil pump damage, filter, filter or oil clogged, lack of oil and several other reasons.

Q:What are the markings on the fuel pump and the oil pump? They can be recognized at once
It looks different
Q:What about the oil quality of automobile engine oil pump?
Take the pressure gauge to measure the pressure
Q:GY6 engine oil pump installation direction, there is an arrow pointing to the other side of the ah
The direction of the arrow indicates the direction of the oil, and the one with the arrow is connected to the engine oil inlet.
Q:How to check the motor oil pump oil supply is normal?
In the premise of the normal amount of oil, usually need to check whether the oil pressure is normal (usually around 0.3MPa), if the oil pressure is low, usually the oil circuit, overflow valve failure or oil pump failure. After cleaning and adjusting the oil relief valve, the pressure is still low. The fault must be the oil pump failure.The effect of the oil pump is to press the engine oil to a certain pressure and force it to the surface of each part of the engine. If the oil pump is damaged or leaking, it is necessary to disassemble the oil pan, take out the oil pump and replace it, and clean or replace the oil pump inlet strainer at the same time.
