It is a small fastener doing a serious job: if it backs out or fails, the impeller moves on the shaft under load and takes the seal plate and often the impeller itself with it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to fit a new one\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eReplace the screw any time the impeller comes off for a seal change or an impeller swap.
