Product details
The Pentair 355385 is the motor support for the Challenger, Pinnacle and Waterfall pumps, listed at 5-5/8 inches in diameter and also described as a motor adapter.
Where it sits
The support is the structural piece between the motor and the wet end. It carries the motor weight and holds the shaft square to the housing, which is what keeps the mechanical seal running true. Once a support has corroded thin or cracked, the motor no longer sits where the design intends and the seal pays for it.
Worth doing during a motor change
This is the kind of part to replace while the pump is already apart. A support that has spent years at the wet end of the pump is usually pitted, and it will be even harder to separate next time. Compare the 5-5/8 inch diameter to the piece you are removing before ordering, and note that the support ships on its own without motor, seal or hardware.
