Correct replacement of hydraulic oil

There are many hydraulic components on construction machinery, and plenty of hydraulic oil is needed. When the hydraulic oil needs to be replaced due to the long time of modification, some people mistakenly believe that only the oil in the hydraulic tank shines and the new hydraulic oil is added. But there are many old hydraulic oil remaining in the hydraulic tubing and hydraulic control valve. When the equipment is used, the mixing of the old and new oil will speed up the deterioration of the new oil.

Change the correct steps should first let the hydraulic oil in the hydraulic oil tank, clean the tank after adding new hydraulic oil, then remove the loop duct, start the engine after low speed operation, the oil pump work, respectively control agencies, by the hydraulic oil will need to update the old oil circuit of the discharge, until the oil return duct the new oil outflow, finally, the oil return duct is connected with the tank, to supplement the new hydraulic oil tank to the specified location.

Of course, this change also has its flaws, said loader with pilot bar, this oil, first idling, the pilot has just 35 kilograms of oil, engine, pilot oil (is new oil) to the return line, is to prepare 3 buckets of hydraulic oil are not necessarily enough, in addition the return pipe, is not the only one, should be removed one by one, one by one to do such a lot of trouble.

As the saying goes: "modaobuwukanchaigong, friends do not bother! Just imagine, this oil change is slow, but also depends on the specific models and circumstances, but this is up to half a day time is enough, this day, this device can earn much money? If a component is damaged due to dirty oil, how much will it cost you only spare parts in addition to maintenance hours and costs? This is definitely not alarmist talk!
