RARAYC Air, Oil, Hydraulic & Fuel Filter Kit — Complete Bobcat 743–T190 Compatible Set with Fuel/Water Separator

Complete maintenance kit with air, oil, hydraulic and fuel filters designed to replace Bobcat part numbers 6598362, 6598492, 6675517, 6667352 and 6661248 for a range of skid steer and track loaders.

Keep core systems running smoothly with this RARAYC multi-filter set engineered for Bobcat models including 743, 751, 753, 763, 773, S130, S150, S205, T140, T180 and T190. The bundle groups inner and outer air elements, a fuel/water separator, an engine oil filter and a hydraulic filter so you can service intake, fuel, oil and hydraulic circuits at once. Each component is made to fit the same mounting points and service intervals as the OE parts listed so shops and fleet owners can swap filters quickly without fabrication or modification.

How does this kit protect engine performance?

The air and oil filters trap contaminants that reduce engine efficiency and accelerate wear. Cleaner intake air and filtered oil preserve cylinder surfaces, rings and bearings, helping the engine keep power and fuel economy under load.

• Inner air element captures fine dust and debris before it reaches the turbo and cylinders
• Outer air element blocks larger particles and extends inner filter life
• Engine oil filter reduces abrasive particles that score bearings and pistons
• Designed to match original mounting and flow characteristics for proper protection

Will these filters fit my Bobcat model and part numbers?

This RARAYC set is manufactured to replace Bobcat reference numbers 6598362, 6598492, 6675517, 6667352 and 6661248 and is compatible with many skid steer and track loader serial ranges. Verify service manuals or your current filter part numbers to confirm fitment before purchase.

• Commonly compatible with skid steer models 751, 753, 763, 773 and S130–S205 series
• Fits track loaders like T140, T180 and T190 within specified serial ranges
• Includes both inner and outer air filters plus fuel/water separator for full intake and fuel coverage
• Check your loader’s parts diagram or stamping to ensure exact part number match

How does the fuel water separator help engine reliability?

The included fuel/water separator removes free water and particulates that cause injector corrosion, poor combustion and pump wear. Removing water at the fuel system inlet prevents downstream damage and helps maintain consistent fuel pressure and spray patterns.

• Traps free water to prevent injector and pump corrosion
• Improves fuel filtration before fuel reaches high-pressure components
• Simple spin-on or element change to match OEM service steps
• Helps avoid downtime caused by contaminated fuel supplies

What benefits does replacing the hydraulic filter provide?

Fresh hydraulic filtration keeps pumps, valves and cylinders free of abrasive particles and varnish, extending component life and improving system responsiveness. Clean hydraulic fluid means smoother control and fewer unexpected failures under heavy duty or continuous operation.

• Removes metal wear particles and debris that damage pumps and valves
• Helps maintain proper flow and pressure for consistent attachment performance
• Supports longer fluid life when used as part of scheduled maintenance
• Manufactured to fit OEM housings for straightforward replacement

Who is this for? Mechanics, rental operators, small fleet managers and owner-operators who service Bobcat skid steer and track loaders will benefit from this RARAYC comprehensive filter kit. It’s built for anyone who needs an all-in-one maintenance solution that matches common Bobcat part numbers, reduces parts sourcing hassle, and helps restore factory-level protection quickly during routine service.
