Original MANN-FILTER Fuel filter WK 850/3 – For Utility Vehicles

Overview of the MANN‑FILTER Fuel Filter WK 850/3

The MANN‑FILTER Fuel Filter WK 850/3 is a high‑performance, screw‑on fuel filter designed specifically for utility vehicles. It delivers reliable protection against contaminants that can damage engines and reduce efficiency. The filter’s compact design and robust construction make it an ideal choice for commercial fleets, agricultural machinery, and industrial equipment.

Key Technical Specifications

• Thread Size: 7/8‑14 UNF‑2B – compatible with most standard fuel lines on utility vehicles.
• Filter Type: Screw‑on (anschraubfilter) for quick installation and maintenance.
• Material: Premium polymer housing with a durable, corrosion‑resistant core.
• Capacity: Designed to handle high fuel flow rates typical of heavy‑duty engines.
• Compatibility: Suitable for a wide range of brands including Caterpillar, Volvo, AGCO, and many others.

Performance Features

The WK 850/3 filter incorporates MANN‑FILTER’s advanced filtration technology. It captures particles as small as 0.5 µm, ensuring that only clean fuel reaches the engine. This level of filtration protects pistons, valves, and injectors from wear, extending service intervals and reducing maintenance costs.

High Flow Rate

Engine performance is maintained thanks to a low pressure drop across the filter. The design allows for uninterrupted fuel delivery even under high load conditions, which is critical for utility vehicles that operate in demanding environments.

Durable Construction

The housing is engineered from high‑strength polymer that resists cracking and deformation under temperature variations typical of diesel and gasoline systems. The filter’s seal integrity ensures a leak‑free operation over extended periods.

Installation Guide

1. Preparation: Turn off the engine and allow the fuel system to drain or relieve pressure.
2. Remove Old Filter: Unscrew the existing filter using a suitable wrench. Dispose of it according to local regulations.
3. Install WK 850/3: Align the threads with the fuel line and screw in clockwise direction until snug. Avoid over‑tightening to prevent damage to the housing.
4. Check for Leaks: After installation, start the engine briefly and inspect the connection for any signs of leakage.

Maintenance Tips

• Replace the filter every 12,000–15,000 km or as recommended by the vehicle manufacturer.
• Inspect the housing for cracks or deformation before each replacement.
• Avoid using incompatible thread sizes; always verify that the 7/8‑14 UNF‑2B specification matches your fuel line.

Applications Across Industries

The versatility of the WK 850/3 makes it suitable for:

• Agricultural Machinery: Tractors, harvesters, and irrigation pumps that require reliable fuel delivery.
• Construction Equipment: Excavators, loaders, and compactors where engine longevity is paramount.
• Industrial Vehicles: Forklifts, generators, and material handling units operating in harsh environments.
