How to Install the Turbine of a Hayward Aquabug

Installing the turbine of a Hayward Aquabug requires no tools, but it does require attention to detail. The bearings must seat properly and the turbine itself must spin in the right direction to provide the power that runs the cleaner during its cleaning cycle. Here's how to install the turbine.

Difficulty: Moderately Easy

Instructions

1. Set the lower middle housing upside down on the work bench with the rear of the housing closest to you. Note that the turbine has stamps with "R" for right and "L" for left. With the rear of the housing facing you, this means your right and your left.

2. Observe that each bearing has a small notch on the inside race. This notch lines up with a ridge on the turbine shaft. Push the bearing onto the shaft with the bearing shield out and the bearing notch lined up with the shaft ridge. This locks the bearing into place on the shaft.

3. Push the turbine into the lower middle housing so the bearings sit in the cradles in the housing, making sure that you have the right and left sides oriented properly. There is another notch on the outside of each bearing. Rotate the outer race of each bearing until you hear the notch click into place, locking the bearing into the cradle.

4. Spin the turbine to be sure it spins freely. Notice that the turbine has an offset cam and the turbine moves slightly up and down as it spins. If you didn't know it's supposed to move in this manner, you might think you didn't seat it properly.
