How To Clean Kubota L3200 And Kubota L4400 Hydraulic Filter?

Hydraulic oil filter elements are generally used in hydraulic stations and hydraulic systems, which need to be cleaned regularly because the filter element has been blocked by the stains in the hydraulic oil after use for a period of time. Therefore, we need to know how to clean the hydraulic filter so as to achieve good filtering effect.

If the hydraulic oil filter element is made of metal mesh or copper mesh, it can be soaked in kerosene for a period of time, and then washed by electric wind, so that the blocked stains can be cleaned up inside.

If the hydraulic oil filter element is made of glass fiber or filter paper, it can not be cleaned, and cleaning does not work. In this case, it is necessary to replace the hydraulic oil filter element.

How To Replace Kubota L3200 And Kubota L4400 Hydraulic Filter?

If it is an oil absorption filter, there is a built-in filter and an external filter, and the built-in oil must be pumped into the filter below the replacement. External directly remove the bolt outside the filter, the filter element will come out. At the same time the oil is locked by the one-way valve will not flow out, very convenient. If it is the oil return filter element, it can be replaced directly.

How To Maintain Hydraulic Filter?

• Before replacing the original hydraulic oil, check the oil return filter element, oil absorption filter element and pilot filter element to see if there are iron scraps, copper scraps or other impurities. If there may be hydraulic components fault, repair and eliminate, clean the system
• When changing hydraulic oil, all hydraulic oil filter elements (oil return filter element, oil absorption filter element, pilot filter element) must be replaced at the same time, otherwise it is equivalent to not changed
• Identify the hydraulic oil label, different grades, different brands of hydraulic oil is not mixed, may react and deteriorate to produce flocculent. It is recommended to use the designated oil of the excavator
• Before refueling, oil absorption filter element must be installed first. The pipe mouth covered by the oil absorption filter element directly leads to the main pump
• Fuel to the standard position. There is usually an oil level gauge on the hydraulic tank. Pay attention to the parking mode, generally all cylinders are fully recovered, that is, the forearm, bucket fully extended and landing
• After filling the oil, pay attention to the main pump to exhaust air, otherwise there is no action in the car temporarily, the main pump abnormal sound (air sonic boom), or the cavitation damage to the main pump. The method of air exhaust is to loosen the pipe joint at the top of the main pump and fill it up directly
