For Zodiac MX8 and MX6 Elite pool cleaner owners, reliable navigation is critical to full pool coverage. One of the key components responsible for powering the left side of the cleaner is the A-Side Drive Mechanism (part #R0524700). When this part begins to fail, you may notice reduced mobility, missed spots, or the cleaner spinning in place.
Replacing the A-Side Drive Mechanism restores your cleaner's ability to climb walls, steer properly, and cover the entire pool floor with precision.
Understanding the A-Side Drive
Each Zodiac MX cleaner uses two internal drive mechanisms (A-side and B-side). These units connect to the cleaner’s gear assembly and turn the tracks that move the unit. The A-side specifically handles rotation and directional control from one half of the cleaner, so when it malfunctions, you’ll often see an imbalance in cleaner motion.
Symptoms of a Failing A-Side Drive
-
The cleaner only moves in circles or not at all
-
The cleaner misses wide sections of the pool
-
Audible grinding or clicking from inside the unit
-
Visual wear or cracks on the gear housing

Final Thoughts
If your Zodiac MX8 or MX6 isn’t navigating properly, the A-Side Drive Mechanism could be the silent culprit. Swapping it out takes only a few minutes and breathes new life into your cleaner, restoring balance, power, and directional control. Keep one on hand for service calls or off-season tune-ups.
