Poor quality machine filters have all the functions they should have, but compared to high-quality ones, each of them has slightly lower processing accuracy, filter paper area, and auxiliary component performance.

The full name of machine filter is engine oil filter. During the operation of the engine, metal shavings, dust, and carbon deposits that are oxidized at high temperatures will constantly mix with the engine oil.

The function of machine filter is to filter out these impurities, maintain the cleanliness of the engine oil, and protect the engine.

The machine filter is bought as an iron can, and I don't know if the quality is good, it's just an iron can. I bought two filters of the same model online, one for 10 yuan and the other for 50 yuan. Take them apart and see what the difference is.

The first trick: "Using appearance to filter" method is actually very effective, because a good filter must have a good appearance. The source of cheap machine filters themselves is very suspicious. Their predecessor may be used waste machine filters, which are refurbished, reassembled, and then sold. Of course, the process can be saved.

The second trick: The rubber rings at the inlet and outlet of the machine filter are also one of the references for judging the quality of the machine filter. You can take off the rubber ring and pinch it with your hands to feel the texture of the rubber ring.

A good machine filter has a thick rubber ring material and a soft feeling when pinched by hand to ensure sealing around the oil inlet and outlet.

The third trick: whether there is a check valve is also an important basis for judging the quality level of a machine filter. You can use the small tools around you to identify whether the machine filter has a check valve structure.

The machine filter check valve is actually a rubber cup, a simple component, but its function is quite important – it can block the oil reflux, ensure that when the engine starts cold, oil pressure can be formed in the lubrication system as early as possible to ensure oil supply, and minimize the dry grinding time of the engine. Simply put, a check valve is a device that allows the lubrication system to store as much oil as possible after the vehicle is turned off.

Fourth trick: Check the fixing degree of the TEREX spare parts filter element of the Terex accessory. A good machine filter will have its filter element firmly fixed inside the machine filter, which will not shift when subjected to oil pressure and vehicle turbulence, to ensure that the oil passes through the filter paper to complete the filtration. So, from the degree of fixation of the filter element, the quality of a machine filter can also be judged.

Fifth move: Shake the filter vigorously and listen for any noise. The judgment basis for this move is the same as the method of touching the inner wall – a good Terex accessory TEREX spare machine filter has better fixation of the filter element, and there is no interference noise from the components when shaking.

What is the interior of the machine filter like?

As the saying goes: Although sparrows are small, they have all five organs! A small machine filter is composed of many components. In addition to the shell, bypass valve, and sealing ring that we can easily see from hand, the filter element and check valve of the machine filter determine the effectiveness of oil filtration. It can be said to be the heart of the TEREX spare parts machine filter for Terex accessories. In addition, the fixed spring serves as a guarantee for the filter element to work in the correct "posture" for a long time.
