How to install and select the oil return filter element?

The oil return filter element is located on the oil return line of the system. Its function is to filter out newly generated or externally intruded dirt in the system before returning it to the fuel tank. Therefore it is the most effective location to control the pollution level of the system. Although it is in a low-pressure pipeline, pulsation or pressure shock will also occur according to the operating conditions of the transmission, so the requirements for the filter element should also be strictly in accordance with the seven standards.
