When the oil filter has been working for a period of time, the pressure of the oil circuit system of the oil filter will increase accordingly, which will have different effects on the performance of its components, especially the filtration accuracy of the filter element has the greatest impact, and even the filter element is damaged. The main reason is It is the pressure difference of the filter element that increases. Therefore, when the oil filter has been working for a period of time, it is required to clean and replace the filter element.
The specific cleaning and replacement methods are as follows:
Cleaning (only for metal mesh filter element):
1. Cleaning cycle: the oil filter works continuously for one week (about 150 hours)
2. Cleaning method:
a. Unscrew the nut on the filter flange, remove the flange, and then take out the filter element.
b. Cleaning the filter element: When cleaning the filter element, after soaking in gasoline for about half an hour, remove impurities with a brush.
Replace:
1. Conditions that need to be replaced: ① When the pressure gauge indicates that the difference is greater than 0.3 MPa, the fine and pre-filter elements need to be replaced at the same time.
2. Replacement method: loosen the screw assembly on the top of the filter, remove the top cover, take out and replace the filter element.
