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.

Questions and answers

What people ask about this product, answered by our pool techs.

Which cleaners does this fit?
Maytronics lists it for use with Dolphin robotic pool cleaners. The available information does not name individual models, so match part number 3883645 against your parts list.
What does TT flat shaft mean?
It identifies the pulley version by the shaft it mounts on. Maytronics builds pulleys for different shaft types, so confirm yours is the flat shaft style before ordering.
Does the color matter?
Yes. Maytronics distinguishes pulley versions by color, and this is the white one. Compare it against the pulley currently in your cleaner.
Should I replace the belt at the same time?
It is worth checking. The belt and pulley wear together, and a new pulley running on a stretched belt will still slip.
