Technical Specifications

Performance Benefits

The WDK 940/5 filter’s advanced media composition ensures that even the finest contaminants are captured before they can reach engine internals. This results in:

• Reduced Engine Wear: By preventing abrasive particles from circulating, the filter protects bearings and camshafts, extending their service life.
• Improved Fuel Efficiency: Clean oil maintains proper lubrication, reducing friction losses and improving overall fuel economy.
• Consistent Engine Performance: Stable oil pressure and temperature are maintained, ensuring reliable power delivery even under heavy load or high‑speed operation.
• Lower Maintenance Costs: The filter’s long service interval reduces the frequency of maintenance visits, saving time and money for fleet operators.

Installation Guide

1. Locate the existing oil filter on the engine block or fuel rail.
2. Use a suitable wrench to loosen and remove the old filter. Be prepared for residual oil; use a catch pan if necessary.
3. Inspect the gasket area for damage or residue. Clean gently with a non‑abrasive cloth.
4. Place the new WDK 940/5 filter onto the mounting surface, ensuring proper alignment of the screw threads.
5. Screw in by hand until snug, then tighten an additional quarter turn with the wrench to secure the seal.
6. Check for leaks around the gasket. If any are detected, re‑tighten slightly or replace the gasket if damaged.

Maintenance Tips

• Inspect the filter housing and gasket periodically for signs of wear or corrosion.
• During routine service intervals, verify that the filter is seated correctly to avoid oil starvation.
• If operating in extremely dusty environments, consider more frequent inspections to ensure optimal filtration performance.
