2. Three-stage fuel filtration system ：
   • 53C0945+40C7018 Diesel filter element: Doubly intercepts water impurities and gum in the fuel, with a mechanically stamped end cap. 20 MPa High-voltage test—no detachment;
   • SP133752 Diesel fine filter element: Designed specifically for high-pressure common-rail systems, 5μm The filtration accuracy prevents nozzle clogging, enhancing fuel injection atomization efficiency. 15% , supporting the engine in 1800 rpm Efficient operation within the commonly used speed range.

(II) Intake Protection Barrier: Designed for Dusty and Heavy-Duty Environments

60C2472 Air filter element : Adopting 52 The evenly pleated design (aftermarket parts generally only 36  Folds), with dust-holding capacity reaching 2.8 kg/m² , in coordination with 5mm Thickened sealing strips ensure zero air leakage. In the dusty environment of mines, they help maintain the cleanliness of the turbocharger system's intake air, preventing PM10 Particles caused by “ Abrasive wear ” , extending the engine's lifespan 3  More than years.

(III) Hydraulic System Safety Barrier: Safeguarding Precise Power Transmission

1. 53C0658 Oil-absorbing filter element : Installed at the oil suction end of the Kawasaki main pump, with an oil flow capacity reaching up to the pump's flow rate. 1.3 Twice as much—mechanical stamping base in 90℃ Under high temperatures, there is no risk of the adhesive layer peeling off, effectively resolving the issue of the main pump seizing up due to dissolution in aftermarket parts.
2. 53C0210 Oil Return Filter Element ： 20μm The filtration precision intercepts valve spool wear debris circulating in the hydraulic oil, forming a closed-loop filtration system with the suction filter element, ensuring that the cleanliness of the hydraulic oil is maintained at a consistently high level. NAS 7 Within the specified level, extend the main pump seal's lifespan to 5000  Hours.
3. 53C0083 Pilot Filter Cartridge : By employing tangential intake separation technology, impurities in the pilot oil are removed, ensuring IPC The valve group in the control system ensures precise response, enabling the instant activation of the automatic digging force enhancement feature.
4. 53C0837 Hydraulic respirator filter cartridge : Maintain a stable pressure difference between the inside and outside of the fuel tank, preventing the hydraulic pump from cavitation due to negative pressure during heavy-load operations. 200L A large-capacity fuel tank strengthens the first line of defense.

3. OEM Quality Endorsement: A Comprehensive Leap from Standards to Value

Liugong SP246021 The entire line of filter cartridges meets ISO 16889 Filter criteria, applied through 1000  Hourly Test Bench Durability Testing:

• Lifespan Advantage: Air filter replacement cycle reaches 2000 Hours (aftermarket parts only) 500-800 Hours);
• Cost advantage: By CLG933E Average annual 3000  Hourly task calculation can reduce the frequency of filter cartridge replacements. 4  Next, avoid main pump repairs caused by the failure of aftermarket parts (with a single cost exceeding 8  Ten thousand yuan) risk;
• Adaptation Assurance: Perfectly matches the pressure curve of the aircraft's hydraulic system, preventing excessive filter element pressure drop that could lead to power loss.

IV. Reimagining Value in Action: Making Every Hour of Homework More Rewarding

During field measurements in the mine, equipped with SP246021 Suitcase set CLG933E：

• Engine failure Downtime Reduce 75%；
• Hydraulic pump volumetric efficiency is maintained at 92% The above (aftermarket parts are compatible only with the following models) 85% );
• Overall maintenance costs decrease 40 Yuan /  Hours.

This kind of “ Preventive Protection ”  The concept ensures that the equipment maintains a stable uptime rate even under heavy-load conditions. 95% The above has become an efficient profit-generating tool for aircraft owners.

V. Scenario-Based Application Guide: Key Protection Focus Areas for Different Operating Conditions

(1) Mine Stripping Scenarios: Addressing Challenges of High Dust and Heavy Loads

The CLG933E operates continuously for 12 hours a day in mining operations, during which the 60C2472 air filter is directly exposed to high-concentration dust generated from ore crushing. Its unique 52-pleat design allows it to capture more dust, while the reinforced sealing gasket effectively prevents unfiltered air from bypassing into the engine. Compared to aftermarket filters, this design reduces replacement frequency by up to three times per month, minimizing downtime for maintenance. Meanwhile, the closed-loop filtration system formed by the 53C0658 oil filter and the 53C0210 return oil filter efficiently traps metal debris produced by rock impacts within the hydraulic system during mining activities, preventing premature wear of the main pump seals and ensuring stable output of approximately 3,000 m³ of material stripped per month per machine.

(2) Large-scale Infrastructure Scenarios: Adapting to Multi-Condition Switching Needs

In highway subgrade construction, the CLG930E frequently switches between digging, breaking, and loading modes, placing extremely high demands on the responsiveness of its hydraulic system. The 53C0083 pilot filter utilizes tangential air intake separation technology to ensure superior cleanliness of the pilot oil, reducing the activation time of the automatic digging-force enhancement function to just 0.8 seconds—representing a 40% improvement in response efficiency compared to filters supplied by aftermarket manufacturers for compatible models. Additionally, the three-stage fuel filtration system (consisting of 53C0945, 40C7018, and SP133752) is designed to handle non-standard diesel fuel from temporary on-site supply points, preventing injector clogging that could cause power fluctuations and ensuring consistent loading efficiency of up to 20 truckloads per day.

6. User Decision Support: Answering Three Core Questions

(1) How to determine whether the filter cartridge needs replacing?

1. Visual Judgment ： 60C2472 The air filter element is equipped with a differential pressure indicator; when the pointer enters the red zone (differential pressure ≥5kPa ) must be replaced immediately;
2. Time cycle : According to LiuGong's maintenance standards, 40C2182 Oil filter every 500  Hourly replacement, 53C0837 Hydraulic respirator filter cartridges every 1000  Replace every few hours; it is recommended to replace the entire kit along with the device. 2000  Hourly major maintenance synchronized update;
3. Operating Condition Adjustment : In high-dust environments such as mines, the replacement cycles for air filters and hydraulic respirator filters need to be shortened. 30% , scenarios involving the supply of substandard fuel need to be addressed in advance 100  Hourly replacement of the diesel filter assembly.

(II) Compared to aftermarket kits, where does the hidden value of factory-installed kits lie?

A certain infrastructure company once used a substandard aftermarket kit to fit the CLG933E. Although the initial purchase cost was 30% lower, three months later, the rubber layer of the 53C0210 return oil filter began to dissolve, leading to hydraulic oil contamination. This forced a major pump repair costing 82,000 yuan and resulted in a 15-day equipment downtime, causing project delays and losses exceeding 200,000 yuan. In contrast, LiuGong’s genuine factory kit passed a rigorous 1,000-hour bench test, eliminating any risk of filter detachment or dissolution. Based on the CLG933E’s expected 5-year service life, this solution could save nearly 600,000 yuan in maintenance and repair costs, delivering an impressive return on investment of 300%.

(3) How can you ensure you're purchasing the genuine package?

Identity Verification : Each set SP246021 All packages are affixed with LiuGong anti-counterfeiting labels. Scanning the label's QR code will take you to LiuGong's official verification page, where product traceability information is displayed.

Packaging details : The original factory packaging uses thickened corrugated cardboard boxes, printed with clear model-specific compatibility markings. CLG930E/CLG933E ) and the model number and production date of each filter cartridge.
