Applications & Compatibility
This replacement motor is suitable for a wide range of pool and spa pumps that accept a 56J / C-face motor with a 5/8″ shaft — common on many single-speed pumps used in residential pools. Ideal for replacing failing or underperforming motors, or when updating an older pump body. Because of its 115/230 V flexibility, it's useful for installations where power configurations may vary.
Installation & Maintenance Tips
- Before installation — verify that your pump wet-end is compatible with a 56J, 1.10 HP, 3450 RPM motor (shaft size, flange bolt pattern, rotation).
- Ensure proper wiring and voltage selection to match your supply (115 V or 230 V) and meet local code.
- When installing, align the motor shaft and impeller carefully to avoid mis-alignment and premature seal or bearing wear.
- Provide adequate ventilation around the motor — although built for continuous-duty operation, good airflow helps prolong motor life.
- Inspect motor shaft and keyway during installation; confirm impeller is correctly seated and secure before restarting.
