Compatible model
Compatible with Komatsu series excavators: PC200-8M0, PC300-8, PC300-8M0, PC350-8, HB205, HB215, etc. Models. Replace the original part number 207-60-71183. It can be directly installed and used.
Structure and Materials
1. Filter Material: High-performance glass fiber composite filter material, multi-layer folded filtering structure, large pollutant retention capacity, stable filtration accuracy, resistant to high-pressure impact, and anti-aging.
2. Outer Layer: Thickened perforated metal protective net, preventing filter material from being deformed under pressure, suitable for harsh working conditions of construction machinery.
3. Sealing Parts: Oil-resistant rubber sealing ring, reliable sealing performance, preventing backflow leakage of oil, avoiding unfiltered oil entering the oil tank for circulation.
4. The whole is a cylindrical return oil filter core structure, convenient for disassembly and assembly, matching the original vehicle installation position, no need to modify the pipeline.
Core Functions
1. Impurity Filtration: Intercept metal debris, sand, sealing rubber materials and other contaminants in the hydraulic oil, maintaining the cleanliness of the hydraulic oil.
2. Component Protection: Avoid scratches on the hydraulic pump and main valve spool by impurities, reducing common faults such as valve jamming, movement sluggishness, and insufficient pressure relief.
3. Working Condition Adaptability: Suitable for mining, earthwork, construction sites with high dust and temperature working environments. The filter core is resistant to deformation and or damage.
4. Maintenance Tips： Replace according to the equipment maintenance cycle; in harsh working environments, it is recommended to shorten the replacement cycle to prevent filter core blockage and excessive back pressure in the return oil.
Installation Precautions
1. Before replacing the filter element, clean the surrounding area of the hydraulic oil tank to prevent dust and impurities from entering the internal oil tank.
2. Check if the rubber sealing ring is cracked or damaged, install it properly to ensure sealing.
3. After replacement, start the equipment to perform reciprocating movements to discharge air from the hydraulic circuit, observe for any leakage.
4. The old filter element is a contaminated part, handle it according to industrial waste regulations, and prohibit reuse.
Common Fault Correlation
Filter Blockage： Increased return oil resistance, resulting in slow movement and abnormal increase in oil temperature.
Filter Breakage Failure： Impurities directly enter the hydraulic system, easily causing pump and valve wear, resulting in high maintenance costs. It is essential to select reliable replacement parts with good quality.
Product advantages
Strictly conforming to the original factory installation dimensions, it has strong interchangeability; the high-capacity filter material extends the service life; the sealing structure is reliable, suitable for continuous operation of heavy-duty construction machinery, and is a must-replacement part for excavators during regular maintenance.
