Technical Specifications

Donaldson Oil Filter Cross Reference

When purchasing an aftermarket oil filter, professional buyers often need more than a single part number. Cross-reference information helps distributors identify alternative filter numbers and reduce the risk of ordering an incorrect replacement. The P550086 reference is associated with multiple equivalent or replacement numbers across different filter suppliers and equipment applications. Public catalog data also lists several commonly associated references, including Komatsu, Fleetguard, Baldwin, Sakura, Wix and other filter numbers.

Engine Protection Oil Filter for Heavy-Duty Applications

Clean engine oil is important for reducing the impact of contaminants circulating through the lubrication system. An effective engine protection oil filter helps capture particles before they continue through the oil circuit. For heavy-duty equipment operating under high loads, long working hours or dusty environments, regular filtration maintenance is an important part of preventive service.

The P550086 replacement is designed around a full-flow lubrication configuration. Its spin-on structure makes it practical for routine maintenance, while the defined thread and gasket dimensions provide key reference points for professional fitment verification. Published specifications identify cellulose filter media, a bypass valve and a 20 micron efficiency reference.

Oil Filter Maintenance Recommendations

• Follow the engine or equipment manufacturer's recommended oil and filter service interval.
• Check the filter part number and dimensions before replacement.
• Inspect the gasket sealing area for damage or contamination.
• Use the correct engine oil and maintain the recommended oil level.
• For equipment operating under severe conditions, consider a more frequent inspection schedule.
• Keep replacement filters stored in a clean and dry environment before installation.
