GIVEN: '95 Frigidaire FWS645RBS1 Washing Machine. NOTE: This model incorporates a PLASTIC tub-spin. PROGRESS REPORT: Have (successfully) removed the five (5) 5/16-18 x 5/8 flange head bolts that secure the tub-spin to the trunnion (? - apologies, if any, for incorrect term). Top panel has been removed to allow unobstructed access to cabinet. OBJECTIVE: I wish to remove tub-spin from unit for thorough cleaning. What is required to "break" that 'Polydent Seal' that exists between tub and trunnion WITHOUT destroying, rendering NFG something/something else in the process? Someone... PLEASE HELP
