How much do you know about the correct installation method of oil filter?

The engine is the heart of engineering machinery, which keeps the whole machine running. During the working process of the engine, metal debris, dust, oxidized carbon deposits and colloidal deposits at high temperature, water, etc. are constantly mixed into lubricating oil. The function of oil filter is to filter out the impurities, gum and moisture in the oil, to deliver clean oil to all lubricating parts, and to prolong its service life. It plays an important role in construction machinery!

I believe there is no need to talk about those superficial truths in front of us. Let's analyze the question of whether the oil filter element should be filled with oil first. Let's take a look at the opinions of netizens first:

Two

Point of view: Fill the oil before changing the filter.

A: The purpose of filling up the oil is to remove the air in the filter element. If there is air, the fluidity of the oil is not good, and it is easy to generate resistance, which will cause some parts to lack oil lubrication for a short time, resulting in wear and tear.

B: The filter element should be filled with oil to ensure uninterrupted lubrication of the machine. When the oil is changed, the old oil is completely emptied. Only a small amount of oil in the filter element can ensure uninterrupted lubrication for the machine before a large amount of new oil is sucked into the oil passage.

Three

Point of view: Replace the filter and inject half the oil into the filter element.

C: Injecting oil into the filter element is mainly to fully wet the inside of the new filter element and increase the tightness of the filter element. So, it's ok to turn it back and forth with half of the filling, there's no need to top it up. If you fill it up before loading it, the oil will easily leak out, and the machine will be covered with oil everywhere.

D: We usually only fill half of the oil into the oil filter, because when the filter is changed and the oil is added to the oil tank, there will be more buffer space in the oil tank. It doesn't matter if you accidentally add too much oil. Too much oil is easily sprayed out of the oil gauge, and you can't take it if you fill it up.
