Oil filter may seem inconspicuous, but it plays an irreplaceable role in construction machinery. First Step: drain the waste oil first drain the waste oil from the fuel tank, place the old oil container under the oil pan, and open the oil release bolt, discharge waste motor oil. When discharging oil, try to let more oil dripping down for a period of time, to ensure that the waste oil discharge clean. (oil through use, will produce a lot of impurities, if the replacement is not clean, easy to plug the oil circuit, resulting in poor oil supply, causing structural wear second step: remove the old oil filter element to the old oil container under the machine filter, remove the old filter element. Be careful not to dirty the inside of the machine with waste oil. The third step: oil filter before the installation of the preparation of this step to tell you to replace the new filter filter need not to fill the filter oil. There are two kinds of oil filter installation, the common is vertical installation, there are many small excavator filter is horizontal installation. Installation is not the same, so full oil is divided into two cases: first, the vertical installation of oil filter, it is connected to the oil pump through an oil pipeline, this installation is generally recommended that the user to replace the filter, go to the filter filled with oil.
If the new filter is not filled with oil, the new filter will have air resistance, landing caused by a short period of lack of oil lubrication in the machine, will cause structural wear. The advantage of the vertical installation is that the filter element has better sealing and less oil leakage. Tips: vertical installation of oil filter correct operation method before changing the filter to find a clean point of the environment, remove the protective film, and then into the new filter filled with oil, oil injection process to pay attention to the surrounding environment, check the oil drum and the oil injection port, make sure not to bring into the soil and other impurities, after filling the oil hand in the oil seal ring also wipe on the oil, increase the sealing. Furthermore, the oil filter element installed transversely is directly connected to the oil pump without passing through the oil pipeline. This design will not cause air resistance inside the filter when the oil is filled into the oil tank, before the filter element is installed, it is not necessary to fill the oil in advance. When the new oil is injected into the oil tank, the oil filter element can be directly filled with oil. Tips: horizontal installation of the oil filter correct operation method in the new oil filter seal by hand on a layer of oil, increase the sealing, and then can be directly installed, during the period also pay attention to the surrounding environment, avoid bringing in impurities when filling the oil.Step 4: Install a new oil filter to check the oil filter installation location of the oil outlet, clean up the above dirt and residual waste oil. Before installation, put the sealing ring on the oil outlet first, and then slowly screw up the new filter, filter don't screw too tight, in general, after tightening by hand, then use a wrench to screw 3/4 turn. Pay attention to the installation of a new filter, do not use wrench twist too hard, or easy to damage the inner seal of the filter, resulting in poor sealing effect, no filtering effect! Step 5: add new oil to the oil tank finally, the new oil into the oil tank, if necessary, to use a funnel to prevent the oil will be poured outside the engine. After the injection, again check whether the lower part of the engine leakage. If there is no leak, check the dipstick to see if the oil is added to the line, we recommend adding it to the line. In the daily work process we also want to check the dipstick regularly, less than the oil off-line words to be added in time.
The oil filter element plays an irreplaceable role in the oil circuit of construction machinery. A small oil filter element seems inconspicuous, but it has an irreplaceable position in the construction machinery. Machinery can not do without oil, just like human body can not do without healthy blood, once the human body lost too much blood or blood qualitative change, life will be seriously threatened. The same is true for machines. If the oil in an engine enters the lubricating oil circuit directly without being filtered by the filter element, it will bring the impurities contained in the oil to the friction surface of the metal and accelerate the wear and tear of the parts, reduce the life of the engine. Although the replacement of oil filter is extremely simple work, but the correct method of operation can extend the life of the machine.
