Detailed Product Description

WIX 51268 is engineered for heavy-duty oil filtration where durability and steady flow matter. The filter’s enhanced cellulose media and 2/20 beta ratio help trap wear particles while supporting the oil volume needs of trucks, farm machinery, construction equipment, mining equipment, and similar service vehicles. Its closed-top design, 5.218-inch height, and 3.691-inch outer diameter top dimensions support straightforward service replacement in the correct application.

This part number is commonly searched as WIX 51268 for service work on equipment platforms that cross-reference with Caterpillar, Fleetguard, Donaldson, Baldwin, and NAPA Gold Filters listings. If you are sourcing a replacement for Volvo, Hino, or Ford heavy-duty equipment, verify the filter dimensions and thread specification against the original part before installation.

What It Helps Address

• Excess engine wear caused by contaminated oil
• Reduced oil flow from a restricted or overloaded filter
• Premature filter failure in severe-duty operating conditions
• Service issues tied to incorrect thread size or filter dimensions
• Maintenance downtime from inconsistent filtration performance

Installation Notes and Tips

Confirm the 1 1/8-16 thread size, height, and outer diameter before installation. Because this filter does not use an anti-drain back valve or bypass relief valve, it should be installed only in the application specified by the equipment manufacturer. Replace the filter during scheduled service and inspect the sealing surfaces for debris before tightening to the recommended specification.

For fitment-based searches, this part is commonly associated with heavy-duty service applications rather than passenger vehicles. Search terms such as WIX 51268 Volvo filter replacement, Hino oil filter service, and Caterpillar heavy-duty spin-on filter replacement are often used when verifying the correct application.

Quality Assurance

WIX positions this filter for OEM-recommended oil and filter change intervals in heavy-duty service. Its corrosion-resistant housing, center tube, and end caps are built to support leak-resistant operation under demanding conditions.
