Case 580D CK Power Shuttle Filter Location

Hi folks. New to the forum and have found it very helpful. Recently purchased a 1988 Case 580D CK backhoe. Changed oil and hydraulic fluids/filters. Cannot locate the shuttle filter. Have looked behind the radiator screen and no sign of one there or having been there. See no sign of plugs indicating the filter had been bypassed by previous owner. Would greatly appreciate any help with this. Photo would be super.



Thank you
