Part # 5039-440
Manufacturer Code 310-1740
Dimensions 7.75" L x 8.5" W x 5" D
Undocumented changes to the 56 frame volute (Waterway part number 315-1820) have made it difficult to identify whether the current replacement part will work with an existing pump. Current volutes will not interchange with older ones. If replacement of the volute is necessary, please replace the entire wet end.

Hi Mark, Could you take a look at this Video on How to Identify Waterway Wet Ends and then reply back to this post with the information discussed in the video. Especially if you can get the part # embossed into the plastic.
