Introduction
The FLTRUCKTOP CP-752-10 Hydraulic Oil Filter Assembly is engineered to provide superior filtration for petroleum-based fluids in various hydraulic systems. This assembly features a high-efficiency 10-micron filter element, designed to capture unwanted particles and contaminants, thereby ensuring the longevity and optimal performance of your hydraulic components.
Built for demanding applications, this filter assembly can withstand a maximum pressure of 200 PSI and supports a flow rate of up to 20 GPM. It is equipped with a 3/4" NPTF port for secure and reliable connections within your hydraulic circuit. The robust construction, utilizing paper and steel materials, ensures durability and consistent performance.

Setup and Installation
Proper installation is crucial for the effective operation and longevity of your hydraulic oil filter assembly. Follow these steps carefully:
- Preparation: Ensure the hydraulic system is depressurized and cool. Gather necessary tools, including wrenches, thread sealant, and a drain pan.
- Mounting: Select a suitable location for mounting the filter assembly, ensuring it is easily accessible for maintenance. Secure the assembly firmly using appropriate mounting hardware (not included).
- Connecting Hydraulic Lines: Identify the inlet and outlet ports on the filter head. Apply thread sealant to the 3/4" NPTF male threads of your hydraulic lines. Carefully thread the lines into the corresponding ports on the filter head. Tighten connections securely to prevent leaks, but do not overtighten.
- System Fill and Bleed: After installation, refill the hydraulic system with the appropriate petroleum-based fluid. Slowly cycle the system to bleed any trapped air, ensuring the filter is fully primed.

Operating Principles
Once installed and the hydraulic system is operational, the CP-752-10 filter assembly functions by directing the hydraulic fluid through its internal 10-micron filter element. As fluid passes through the element, solid contaminants and particles larger than 10 microns are trapped, preventing them from circulating further into the system. This continuous filtration process helps maintain fluid cleanliness, reduces wear on pumps, valves, and cylinders, and extends the overall lifespan of the hydraulic system.
Maintenance
Regular maintenance, particularly filter element replacement, is essential for the optimal performance of your hydraulic system. The filter element will gradually accumulate contaminants, leading to increased pressure drop and reduced flow.
Filter Element Replacement:
- Frequency: The replacement interval depends on the system's operating conditions, fluid cleanliness, and contamination levels. Monitor system pressure gauges for signs of increased pressure drop across the filter, indicating a clogged element.
- Procedure:
- Depressurize the hydraulic system completely.
- Place a drain pan beneath the filter assembly to catch any residual fluid.
- Unscrew the filter canister from the head.
- Remove the old filter element and dispose of it properly.
- Clean the filter head and ensure the sealing surfaces are free of debris.
- Lubricate the new filter element's O-ring with clean hydraulic fluid.
- Install the new filter element and screw the canister back onto the head until hand-tight, then tighten an additional 1/2 to 3/4 turn as specified by the manufacturer (if applicable).
- Re-pressurize the system slowly and check for leaks.
Troubleshooting
This section provides solutions to common issues you might encounter with your hydraulic oil filter assembly.
| Problem | Possible Cause | Solution |
|---|---|---|
| Reduced Flow Rate / High Pressure Drop | Clogged filter element | Replace the filter element. |
| Leaks at Connections | Improperly tightened fittings, Damaged O-rings or seals | Tighten connections to specifications. Inspect and replace damaged O-rings or seals. |
| Unusual Noise from System | Air trapped in the system | Bleed air from the hydraulic system according to equipment manufacturer's guidelines. |
| Short Filter Lifespan | Excessive system contamination, Incorrect filter application | Identify and address sources of contamination. Ensure the filter is correctly sized and rated for the application. |
