How do I tell if my pump is 48-frame or 56-frame?
Check the motor data plate -- it lists the NEMA frame size. 48-frame motors are physically shorter than 56-frame. The shaft thread and seal seat diameters differ between the two.
Does this fit Leisure Bay Cyclone pumps?
No -- Cyclone uses APCK1049 (and the Cyclone Union kit is APCK1050).
Can I install this myself?
Yes. Disconnect power, separate the wet-end, swap the seal and O-rings, lubricate with pool-grade silicone, and reassemble in a star pattern.
