Detailed Product Description
The Vital Role of Fine Fuel Filtration
A fuel filter is a specialized component designed to remove water and solid abrasive contaminants from the fuel before it reaches the fuel injection pump. The 40C6996 provides critical secondary-stage filtration, ensuring that modern high-pressure common rail (HPCR) systems remain free from microscopic debris. By maintaining the integrity of the fuel stream, this filter prevents injector nozzle wear and preserves engine combustion efficiency.
Solving Premature Component Failure
Contaminated fuel is the leading cause of power loss and injector failure in heavy machinery like SANY cranes and Komatsu excavators. The 40C6996 addresses this pain point by utilizing advanced cellulose media that offers a balance between high flow capacity and strict particle retention. This ensures that even under the extreme pressures of a Cummins 3959612 system, your engine receives clean, debris-free fuel.
Why Choose Our Filtration Solutions?
Our filters are built to bridge the gap between expensive OEM parts and unreliable aftermarket alternatives. The 40C6996 offers:
- Standardized Dimensional Accuracy: Matches the 3.68 inch (93.47 mm) outer diameter perfectly for a leak-free fit.
- Reliable Sealing: Equipped with a high-grade gasket with a 2.83 inch (71.88 mm) OD to withstand thermal expansion and contraction.
- Cross-Industry Versatility: Engineered to meet the technical requirements of diverse brands such as Atlas Copco, Ford, and MAZ.
Engineered for Global Machinery
From the construction sites of SANY equipment to the logistical routes of KAMAZ trucks, the 40C6996 is the standard for durability. It is optimized for the 60510 and 6520 vehicle series, providing the same reliability as a Donaldson P550774 at a more competitive price point.

FAQ
Q: How often should I replace my 40C6996 fuel filter?
A: For heavy machinery like SANY cranes, we recommend replacement every 500 hours or according to your engine's OEM maintenance schedule. Frequent changes are vital if you are using lower-quality fuel sources.
Q: Is the 40C6996 compatible with Cummins 3959612?
A: Yes, the 40C6996 is a direct technical replacement for Cummins 3959612, matching all mounting dimensions and filtration micron ratings.
Q: What is the benefit of 6.5-micron filtration?
A: A 6.5-micron rating ensures that extremely fine particles, which can score fuel injector seats and nozzles, are trapped before they reach the engine. This is critical for meeting Tier 3 and Tier 4 emission standards.
Q: Can I use this filter on a Komatsu engine?
A: If your Komatsu equipment requires part number 6003193750, the 40C6996 is the correct interchangeable part.
Q: What is the gasket size for the 40C6996?
A: The gasket has an outer diameter of 2.83 inches (71.88 mm) and an inner diameter of 2.46 inches (62.48 mm).
