Product Overview
3987171 Caterpillar Hydraulic Filter (398-7171) is a high-reliability hydraulic filter. Specifically, it is engineered to meet Caterpillar’s strict OEM standards, ensuring efficient filtration of hydraulic fluid for Caterpillar equipment, protecting hydraulic systems from wear and damage caused by fluid-borne contaminants.
It effectively filters out solid contaminants such as metal particles, dirt, and debris from hydraulic fluid. By doing so, it keeps the fluid clean, maintains optimal hydraulic system performance, and extends the service life of hydraulic components like pumps, valves, and cylinders.
Crafted with high-quality filter media, it delivers consistent filtration efficiency and strong dirt-holding capacity. Additionally, its precise dimensional design (D1, D2, D3, H1) ensures seamless fitment with compatible Caterpillar hydraulic systems.
Designed for easy replacement and maintenance, it adapts to diverse heavy-duty operating environments. Moreover, its reasonable weight and volume balance durability and portability, making it convenient to handle during maintenance.
Key Features
High-efficiency hydraulic fluid filtration: Effectively captures fluid-borne contaminants of various sizes. For example, it filters out fine metal shavings and dirt particles that can cause abrasive wear to critical hydraulic components.
Precise dimensional design guarantees perfect fitment: D1=110.000 mm, D2=68.000 mm, D3=66.000 mm, H1=405.000 mm. Thus, it aligns seamlessly with Caterpillar OEM hydraulic filter housings and mounting points.
High-quality filter media resists clogging and hydraulic fluid degradation, even in high-temperature and high-pressure hydraulic environments. Moreover, it maintains stable filtration performance and extends service intervals.
Optimized weight (1.740 kg) and volume (0.005082 m³) balance durability and practicality. Furthermore, it simplifies installation and handling, reducing maintenance time and equipment downtime.
Robust structural design withstands hydraulic system pressure and engine vibration. Also, it ensures long-term reliability in heavy-duty construction, agricultural, and industrial hydraulic applications.
Filtration Performance
The filter’s high-efficiency media effectively captures hydraulic fluid-borne contaminants, ensuring clean fluid circulates throughout the hydraulic system. As a result, it prevents abrasive wear on hydraulic components and maintains optimal system operation.
It maintains consistent filtration performance across a wide range of operating conditions. Specifically, it works reliably in high-pressure hydraulic environments, adapting to diverse working scenarios such as construction sites and agricultural fields.
Optimized flow design ensures minimal impact on hydraulic fluid flow rate. Consequently, it preserves hydraulic system power and responsiveness while delivering superior contamination removal.
Strong dirt-holding capacity extends filter service life. In addition, this reduces filter replacement frequency and lowers maintenance costs for equipment fleets.
Structure & Durability
Robust housing withstands high hydraulic fluid pressure and mechanical vibration. Additionally, it resists deformation and damage to ensure long-term reliability in heavy-duty hydraulic applications.
Precise dimensional tolerance (D1=110.000 mm, D2=68.000 mm, D3=66.000 mm, H1=405.000 mm) ensures a secure, leak-proof fit. Not only that, but it also aligns perfectly with Caterpillar’s original hydraulic filter mounting points.
Filter media is resistant to hydraulic fluid corrosion and high-temperature degradation. At the same time, it maintains stable filtration performance over time, even in harsh operating environments.
Its 1.740 kg weight and 0.005082 m³ volume make it easy to handle, simplifying installation and replacement. Besides, it fits seamlessly into tight hydraulic system compartments without modifications.
