Product Overview
Bobcat identifies 6661022 as the anodized aluminum in-line case-drain filter housing. It protects the hydraulic system by holding the replaceable 40-micron element in the case-drain circuit.
The filter element is a separate service part: Bobcat 6661807. The source title only mentions 425/428 excavators, but Bobcat lists the housing across many skid-steer and compact-track loaders as well.
