A case drain filter is a small hydraulic filter element used in certain systems to filter oil returning through a case drain/return circuit. Its job is to catch fine debris before oil returns to the hydraulic tank or system, helping reduce contamination and wear. Not every Bobcat uses the same style, so part-number matching is the most reliable way to confirm the correct filter.
