Revisions N and lower were built with a double stepped shaft at the impeller, and those pumps need a seal with a 13\/16 inch inside diameter on the ceramic portion, which is this one. Revisions P and higher have no step where the impeller goes onto the motor shaft, and they take a 5\/8 inch ID seal instead, part number R0479400.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCheck before you order\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe quickest check is the shaft itself.
