Thoroughly clean the pipe joints of the hydraulic filter element of the Cat excavator, the joints between the pump and the motor, the oil drain plug, the oil filler cap at the top of the fuel tank and the oil drain plug at the bottom and its surroundings with gasoline.

Precautions for cleaning the hydraulic filter element of Cat excavator

During maintenance, remove the hydraulic oil tank filler cap, filter cover, inspection hole, hydraulic oil pipe and other parts. When the oil passage of the hydraulic system is exposed, avoid dust, and the disassembled part must be thoroughly cleaned before opening. For example, when removing the oil filler cap of the hydraulic oil tank, first remove the soil around the oil tank cap, loosen the oil tank cap and remove the debris remaining in the joints (do not rinse with water to prevent water from infiltrating the oil tank), and open the oil tank cap after confirming that it is clean. When wiping materials and hammers need to be used, wiping materials that do not lose fiber impurities and special hammers with rubber attached to the striking surface should be selected. Hydraulic components and hydraulic hoses should be carefully cleaned and dried with high pressure air before assembly. Choose a well-packaged genuine filter element (if the package is damaged, although the filter element is in good condition, it may be unclean). Clean the hydraulic filter element of the caterpillar excavator at the same time when changing the oil. Before installing the filter element, use the rubbing material to carefully remove the dirt inside the filter housing. The cleaning oil of the hydraulic system of the Caterpillar excavator must use the same grade of hydraulic oil used in the system, the oil temperature is between 45-80 ℃, and the impurities in the system should be taken away as much as possible with a large flow rate. The hydraulic system should be repeatedly cleaned more than three times, and all the oil should be released from the system after each cleaning while the oil is hot. After cleaning, clean the filter, replace the new filter element and add new oil

Excavator filter element

Caterpillar excavator hydraulic filter element filter material

Caterpillar excavator hydraulic filter element material Paper filter element Chemical fiber filter element: glass fiber metal fiber sintered felt polypropylene fiber polyester fiber mesh filter element: stainless steel mesh caterpillar excavator filter element material mainly includes stainless steel powder sintered filter element, stainless steel composite mesh sintered filter element, stainless steel woven mesh And so on, there is PTFE polytetrafluoroethylene pleated filter element, but PTFE needs to be lined with stainless steel skeleton material to cope with the possible deformation of the filter element skeleton caused by high temperature. Line gap filter element is installed in the filtration equipment and is used to separate the material. According to the material and the use, it can be divided into many kinds.

caterpillar excavator hydraulic filter features

1. High filtration precision: filter out all larger particles (>1- 2 um)

2. caterpillar excavator hydraulic filter element has high filtration efficiency: reduces the number of particles passing through the filter.

3. Prevent early wear and tear of the engine. Prevent air flow meter damage!

4. The pressure difference is low to ensure the proper air-fuel ratio of the engine. Reduce filtration loss.

5. Large filter area, high ash capacity and long service life. Reduce operating expenses.

6. Small installation space and compact structure.

The filter layer of the caterpillar excavator filter element is made of non-composite glass fiber filter material, and the filtering performance is good. are very important.
