Gear oil pump leaks are common and headaches.Many technicians may have their own methods for dealing with this accident, but there are still many people who do not know how to solve it, and cannot fundamentally solve the problem. First of all, they must understand what caused the low-pressure gear oil pump operation leakage. 1. The oil quality is not clean and the oil return is not smooth. 2. The gland is installed incorrectly, and the drain holes on the front cover and the rear cover are leaked. 3. The outer diameter of the seal ring fits too loosely with the diameter of the seal seat. 4. The pump body of the low-pressure gear oil pump is installed in the reverse direction, so that the oil pressure port is connected to the unloading groove, and a pressure is formed to punch out the seal ring. 5. Seal selection and installation are not tight.The selection of the seal is very important, and it must be installed well. Some parts must be closely coordinated. If a leak occurs, first check whether the seal selection and installation are correct, and then check whether the working conditions are stable. Only by understanding the cause of the leakage of the low-pressure gear oil pump can we better solve the problem.Here are just a few points. In fact, there are many problems about gear oil pump leakage. If you need to know more, please consult.
