Original MANN-FILTER Oil Filter WK 962/5 – For Trucks, Buses and Utility Vehicles

MANN‑FILTER Oil Filter WK 962/5

The MANN‑FILTER Oil Filter WK 962/5 is engineered specifically for heavy‑duty vehicles such as trucks, buses and utility vehicles. Its design focuses on delivering reliable protection for the engine’s lubrication system under demanding operating conditions.

Key Design Features

• High‑Capacity Filter Media: The filter employs a multi‑layered media structure that captures fine particles while maintaining low pressure drop, ensuring optimal oil flow and engine performance.
• Robust Housing Construction: Made from durable polypropylene with reinforced seams, the housing resists deformation and corrosion even in harsh environments.
• Secure Mounting System: The filter features a threaded connection that aligns precisely with standard truck and bus oil filter fittings, guaranteeing a tight seal without the need for additional gaskets.
• Extended Service Life: Designed to meet or exceed OEM specifications, the WK 962/5 offers an extended service interval compared to many aftermarket alternatives.

Performance Characteristics

The filter’s performance is validated through rigorous testing that measures particle retention, pressure drop, and flow rate. Key metrics include:

• Particle Retention: Capable of capturing particles as small as 5 µm with a retention efficiency above 99.9%.
• Pressure Drop: Maintains a low differential pressure (typically 0.2 psi) across the filter during normal operating conditions, reducing engine load.
• Flow Rate: Supports high flow rates necessary for large displacement engines, ensuring adequate lubrication even at peak performance.

Installation Guidelines

Installing the MANN‑FILTER Oil Filter WK 962/5 is straightforward and follows standard procedures used in commercial vehicle maintenance:

1. Drain the engine oil completely to avoid contamination.
2. Remove the old filter, taking care not to damage the mounting surface.
3. Clean the mounting area with a solvent‑free cloth to remove any residue.
4. Place the new filter onto the housing, ensuring that the threaded end is aligned correctly.
5. Tighten the filter by hand until it is snug, then give an additional 1/4 turn with a wrench—do not overtighten.
6. Reinstall the oil drain plug and refill the engine with fresh oil.

Compatibility Overview

The WK 962/5 is compatible with a wide range of heavy‑duty engines, including:

• Diesel engines used in long‑haul trucks and regional delivery vehicles.
• High‑torque engines found in buses and transit coaches.
• Utility vehicle engines that operate under continuous load conditions.

Its universal design allows it to fit most standard filter housings with a 93 mm diameter, making it an ideal choice for fleet operators seeking consistency across multiple vehicle types.

Maintenance Benefits

• Reduced Engine Wear: By trapping contaminants before they reach critical engine components, the filter helps extend bearing life and reduce wear on pistons and valves.
• Improved Fuel Efficiency: Maintaining optimal oil flow reduces friction losses, contributing to better fuel economy over time.
• Lower Total Cost of Ownership: The filter’s durability and performance translate into fewer replacements and less downtime for maintenance crews.

Quality Assurance

MANN‑FILTER is a globally recognized brand known for its stringent quality controls. Each WK 962/5 unit undergoes:

• Pre‑manufacturing inspection of raw materials.
• In‑process testing to verify media density and flow characteristics.
• Final product testing that includes pressure drop, particle retention, and dimensional accuracy checks.

This comprehensive approach guarantees that every filter meets the high standards expected by commercial vehicle operators.

Environmental Considerations

The WK 962/5 is manufactured with sustainability in mind:

• Use of recyclable polypropylene reduces environmental impact.
• Efficient media design minimizes oil consumption, lowering overall emissions.
• Extended service intervals reduce the frequency of filter disposal and associated waste.

Conclusion

The MANN‑FILTER Oil Filter WK 962/5 stands out as a reliable, high‑performance solution for trucks, buses, and utility vehicles. Its robust construction, proven filtration efficiency, and ease of installation make it an essential component in maintaining engine health and ensuring operational reliability across demanding commercial fleets.
