What Does the Dolphin Drive Pulley Do?

The drive pulley forms part of your Dolphin robotic pool cleaner's mechanical drive system.

It helps support the movement of the drive tracks, allowing the cleaner to travel around the pool and climb walls where supported by the model.

Over time, drive pulleys can become worn, damaged or difficult to rotate, which may affect the cleaner's movement and place additional resistance on the drive system.

Common Signs Your Drive Pulleys May Need Replacing

You may need to inspect or replace your Dolphin drive pulleys if your cleaner is experiencing:

• Difficulty moving around the pool

• Drive tracks slipping or coming off

• Grinding, clicking or unusual mechanical noises

• Excessive wear around the pulley

• Stiff or seized pulley bearings

• Uneven or inconsistent movement

• Cleaner starting and stopping unexpectedly

Important: These symptoms can also be caused by worn tracks, other drive components or motor faults. We recommend inspecting the complete drive system before ordering replacement parts.

Why Replace Both Drive Pulleys Together?

When one drive pulley becomes worn, the other may also have experienced similar wear.

Replacing both pulleys during a service can help:

• Restore smoother drive system operation

• Reduce unnecessary resistance

• Improve the operation of the drive tracks

• Reduce uneven wear on associated components

• Avoid dismantling the cleaner again to replace another worn pulley

• Help maintain reliable movement around the pool

This pack contains 2 drive pulleys, making it a convenient option for servicing both components together.

Check Your Dolphin Drive Tracks

When replacing drive pulleys, we also recommend inspecting your Dolphin's timing tracks, drive gears and other associated mechanical components.

Worn, stretched or damaged drive tracks can cause slipping or poor movement even after new pulleys have been fitted.

Replacing worn components together can help restore smoother operation and reduce unnecessary strain on the drive system.
