Product details
The Maytronics 3883645 is the white TT flat shaft drive pulley used on Dolphin robotic pool cleaners. It is the genuine Maytronics part.
Where it sits
Inside a Dolphin, the drive motor turns a belt that runs over pulleys to drive the brushes and the tracks. The pulley is a small part carrying continuous load in water, and when its teeth or its bore wear, the belt starts to slip. The symptom looks like a motor problem: the cleaner powers up and the motor runs, but the machine crawls, stalls on the wall or leaves the floor poorly scrubbed.
Getting the right version
Maytronics builds this pulley in more than one form. This is the flat shaft TT version in white, so compare both the shaft style and the color against the part in your cleaner, and check part number 3883645 against your model parts list. While the machine is open, look at the condition of the belt as well, since the two wear together.
