Bobcat 6661248 is a spin-on hydraulic oil filter positioned between the hydraulic pumps and critical downstream components on Bobcat skid steer loaders, compact track loaders, and mini excavators.

The filter's synthetic pleated filter media and spiral center tube work together to catch contaminants before they reach pumps, valves, and cylinders.

Contaminated hydraulic fluid is one of the leading causes of premature pump and valve failure on compact equipment. As particles circulate through the system, they score valve spools, accelerate seal wear, and cause control response to degrade. This often occurs long before a visible failure occurs.

Replacing the filter at regular intervals with this OEM unit keeps the hydraulic circuit clean, protects high-cost components from abrasive wear, and maintains consistent pressure and response across all machine functions.
