How to identify your bearings
- Unplug the pump or isolate it at the breaker, then take the motor apart far enough to see both bearings. Discharge the run capacitor first.
- Measure each bearing: the bore (the hole), the outside diameter and the width, in millimetres, with vernier callipers.
- Match the kit by the pumps it is listed for, or send us a photo of the old bearings and the pump label and we will check it for you.
- Check the seal too. If the shaft feels rough or the motor grinds, a leaking seal is the usual way water reaches the bearings.
