Technical Specifications

Installation & Compatibility Notes
Before installing, shut off the pool pump and relieve suction pressure. Disconnect the cleaner from the hose and remove the top cover or shroud as required. Remove the worn oscillator assembly, clean mounting surfaces, install the GW9503 kit and reassemble the cleaner. After reconnecting and restarting the system, verify that the cleaner now turns properly, navigates corners and covers the pool as expected.
Maintenance Tips
- Check for reduced turning behavior, stuck wheel movement or cleaner repeating paths — symptoms indicating the oscillator may be worn.
- Replace the oscillator assembly rather than other parts if turning becomes erratic or the cleaner seems locked in one area.
- Stock this kit on your service vehicle or in your parts inventory to quickly address cleaner movement failures.
Why Choose This Kit?
For pool service professionals and serious pool owners, the GW9503 kit offers a practical, effective solution to restore cleaner coverage and avoid full cleaner replacement. By using the correct OEM-style part, you ensure continued reliability and reduce service callbacks.
