High quality Hydraulic oil filter RE573817 for JOHN DEERE 8245R

What is hydrualic filter ?

The hydraulic oil filter element is used in the hydraulic system to filter out solid particles and colloidal substances in the working medium. As well as filtering out various oil systems from external mixing
It can effectively control the pollution degree of the working medium and protect the normal operation of the mechanical equipment. It is an indispensable part of the pipeline series for conveying the medium. The hydraulic oil filter element is equivalent to the heart of the hydraulic oil filter. Only with high-quality hydraulic oil filter element can the hydraulic system work better. The hydraulic oil filter element is mainly made of stainless steel woven mesh, sintered mesh, and iron woven mesh. Because the filter materials it uses are mainly glass fiber filter paper, chemical fiber filter paper, and wood pulp filter paper, it has high concentricity and high pressure. , Good straightness, its structure is made of single-layer or multi-layer metal mesh and filter material, the number of layers and the mesh number of the mesh are determined according to different use conditions and uses. Hydraulic oil filter elements are widely used in steel, electric power, metallurgy, shipbuilding, aviation, papermaking, chemical industry, machine tools and construction machinery, construction machinery and other fields. The following editor will introduce to you the correct use method of hydraulic oil filter element, life-affecting factors, scope of application, quality identification method, replacement method, maintenance method and purchase method. Let’s have a look!

Correct use of hydraulic oil filter element

1. Before replacing the hydraulic oil filter element, drain the original hydraulic oil in the box, and check the three hydraulic oil filter elements of the oil return filter element, the oil suction filter element and the pilot filter element.
If there are iron filings, copper filings or other impurities, there may be a malfunction of the hydraulic components where the hydraulic oil filter element is located. After overhauling and eliminating, clean the system.
2. When replacing hydraulic oil, all hydraulic oil filter elements (oil return filter element, oil suction filter element, pilot filter element) must be replaced at the same time, otherwise it is equivalent to not changing. 3. Identify the hydraulic oil labels. Do not mix hydraulic oils of different labels and brands, which may cause the hydraulic oil filter element to react and deteriorate and produce floccules. 4. The hydraulic oil filter element (oil suction filter element) must be installed before refueling. The nozzle covered by the hydraulic oil filter element directly leads to the main pump. If impurities enter, the speed will be accelerated.
The main pump is worn, and the pump will be hit if it is heavy.
5. After adding oil, pay attention to the main pump to exhaust air, otherwise, the whole vehicle will not move temporarily, the main pump will make abnormal noise (air sonic boom), and the cavitation will damage the hydraulic oil pump.
The air exhaust method is to directly loosen the pipe joint on the top of the main pump and fill it up directly.
6. Regularly do oil testing. The hydraulic filter element is a consumable item, and it needs to be replaced immediately after it is usually blocked. 7. Pay attention to flushing the system oil tank and pipelines, and pass the refueling device with filter when refueling.
8. Do not let the oil in the fuel tank come into direct contact with the air, and do not mix old and new oil, which is helpful to prolong the service life of the filter element.
