Product details
The Hayward SPX4000DLT is the genuine strainer cover kit for the NorthStar pump. It is supplied as a kit with the lid, the lock ring and the o-ring, and the lid measures 9-5/8 inches across the outside diameter.
Check the fitment
The source describes the fit two ways: as NorthStar pumps built before 2008, and as pumps manufactured between 2003 and 2007. Both readings are given here rather than picking one. Measuring the lid you have is the reliable check, since the 9-5/8 inch outside diameter is fixed regardless of which reading applies.
Why the whole kit
The three pieces wear as a set. The lid hazes and crazes from sunlight and chemicals, the lock ring loses its grip, and the o-ring flattens. Replacing only one of them usually means going back in a season later, so the kit is the sensible repair.
The symptom it fixes
Air on the suction side. If the strainer pot will not fill, the pump loses prime, or you can see bubbles in the basket while it runs, the cover assembly is the first place to look before pulling the pump apart.
