Mann Filter W 723/3 Hummel Lube Filter

The Mann Filter W 723/3 Hummel Lube Filter is a high‑performance oil filter designed for industrial, agricultural and construction machinery. It combines the proven filtration technology of Mann with the advanced sealing system of Hummel to deliver reliable protection for engines, hydraulic systems and other lubricated components.

Key Features

• Robust Construction: Heavy‑duty stainless steel housing resists corrosion and withstands harsh operating environments.
• Advanced Filter Media: Multi‑layer filtration media captures particles down to 0.5 µm, ensuring clean oil flow and extended engine life.
• Hummel Sealing Technology: The patented Hummel seal provides a leak‑proof connection, preventing oil spillage during installation or operation.
• Wide Compatibility: Suitable for a broad range of engines and hydraulic units, including Mercedes‑Benz, Perkins, Massey Ferguson, JCB, and many off‑highway machines.
• Easy Installation: Screw‑on design with a standard 3/4‑16 UNF thread allows quick replacement without special tools.

Technical Specifications

Applications

The W 723/3 filter is engineered for use in:

• Engine lubrication systems of heavy‑duty diesel engines.
• Hydraulic oil circuits in construction equipment such as excavators, loaders and backhoes.
• Transmission fluid lines in agricultural machinery.
• Off‑highway vehicles including trucks, tractors and specialized industrial machines.

Benefits for Operators

• Extended Engine Life: By removing contaminants that cause wear, the filter reduces maintenance intervals.
• Improved Fuel Efficiency: Clean oil maintains optimal viscosity and flow characteristics, lowering fuel consumption.
• Reduced Downtime: The leak‑proof Hummel seal eliminates fluid loss during installation, preventing costly repairs.
• Consistent Performance: Stable pressure drop ensures reliable hydraulic response even under heavy load.

Installation Guide

1. Turn off the engine and allow the oil to drain completely.
2. Remove the old filter by unscrewing it counter‑clockwise. Dispose of the used filter responsibly.
3. Clean the mounting surface with a lint‑free cloth to remove any debris.
4. Apply a thin layer of fresh oil to the Hummel seal if recommended by the manufacturer.
5. Screw the new W 723/3 filter clockwise until it is snug. Do not overtighten; a torque of approximately 12 Nm is sufficient for most applications.
6. Re‑fill the system with the appropriate oil type and quantity as specified in the equipment manual.
7. Start the engine and check for leaks around the filter housing.

Maintenance Tips

• Inspect the filter regularly for signs of wear or clogging, especially after heavy usage.
• Replace the filter at intervals recommended by the equipment manufacturer or when oil contamination levels rise.
• Avoid using incompatible oils; always adhere to the viscosity and additive specifications required by the machinery.
