Heavy Equipment Filters

Heavy equipment works long hours in dust, mud, heat and cold, and its engines and hydraulic systems depend on clean oil, fuel, air and hydraulic fluid. This page groups replacement filters for heavy equipment, including excavators, wheel loaders, bulldozers, motor graders, backhoe loaders, cranes and articulated dump trucks, so buyers can find the right filter by machine, engine or part number.

Heavy Equipment Filter Types

• Engine oil filters: spin-on and cartridge filters that protect bearings and turbochargers
• Fuel filters and fuel/water separators: keep dirt and water out of high-pressure injection systems
• Air filters: primary and safety elements for dusty job sites
• Hydraulic filters: return, pressure, suction, pilot and breather filters that protect pumps, valves and cylinders
• Cabin air filters: keep dust out of the operator’s cab
• Air dryer cartridges: for equipment with air brake systems

Machines and Engines Covered

Our heavy equipment filters are matched to machines from leading makers such as Caterpillar, Komatsu and Volvo Construction Equipment, and to the Cummins, Perkins and Weichai diesel engines found in many other makes. Brand names are used only to show which machines and engines each filter is compatible with.

2. Check the engine model on the engine data plate.
3. If possible, read the part number on the old filter.
4. Send us this information, and we will confirm the correct filter.

Heavy Equipment Filter Maintenance Tips

• Service intervals are measured in operating hours. Follow the schedule in the operator’s manual.
• Work in quarries, demolition and dry soil clogs air filters much faster, so check the restriction indicator often.
• Replace the hydraulic return filter together with pilot and breather filters to keep the hydraulic system clean.
• Replace the fuel/water separator and main fuel filter together, and drain the separator regularly.
• Buy complete service kits where possible so no filter is missed.
