Mann Filter WD 8002 Engine Blocks

Mann Filter WD 8002 Engine Block Oil Filter

The WD 8002 Engine Block Oil Filter is a high‑performance filtration solution engineered by Mann Filter for heavy‑duty and industrial applications. Designed to fit a wide range of engine blocks, this filter delivers superior protection against contaminants while maintaining optimal oil flow under demanding operating conditions.

Key Design Features

• Robust Construction: The filter housing is fabricated from high‑strength alloy steel, providing excellent resistance to corrosion and mechanical stress. This ensures long service life even in harsh environments.
• Advanced Filter Media: Inside the housing lies a multi‑layered filtration media stack that captures particles as small as 0.5 µm. The media is engineered for high retention of iron, carbon, and other engine debris while allowing free oil flow.
• Threaded Screw‑On Seal: A precision‑machined threaded seal (3/4‑16 UNF) guarantees a tight fit on standard engine block ports. The screw‑on design eliminates the need for additional gaskets or sealing compounds, simplifying installation.
• High‑Pressure Compatibility: Rated for pressures up to 150 psi, the WD 8002 can handle the elevated oil system pressures found in heavy machinery and industrial engines.

Performance Characteristics

The WD 8002 is engineered to maintain a low pressure drop across the filter while providing maximum contaminant removal. Typical performance metrics include:

• Pressure Drop: ≤ 4 psi at standard operating flow rates.
• Filtration Efficiency: ≥ 99.9% for particles ≥ 0.5 µm.
• Flow Capacity: Maintains > 90% of nominal oil flow after 200 hours of operation under normal load conditions.

Compatibility and Applications

The WD 8002 is designed to fit a broad spectrum of engine block ports, making it suitable for:

• Heavy‑duty diesel engines used in construction equipment, agricultural machinery, and industrial generators.
• Hydraulic power units where oil cleanliness directly impacts hydraulic performance.
• Non‑road applications such as marine propulsion systems and off‑highway vehicles.

Its universal thread size (3/4‑16 UNF) allows seamless integration with existing engine block designs without modification. The filter’s compact dimensions (80 mm diameter) enable installation in tight spaces commonly found in modern machinery.

Installation Guidelines

1. Preparation: Clean the engine block port thoroughly to remove any loose debris or old gasket material. Inspect for damage or wear that could compromise sealing.
2. Seating the Filter: Align the threaded end of the WD 8002 with the port and hand‑tighten until snug. Use a torque wrench to apply the manufacturer’s recommended torque (typically 12–15 ft‑lb) to ensure an airtight seal without over‑torquing.
3. Verification: After installation, run the engine at low speed for a few minutes and check for oil leaks around the filter housing. A properly seated filter will exhibit no external leakage.
