Century replacement pool pump motor – 3/4 HP, 230V, two speed, 56Y frame

⚙️ What this motor is

This is a replacement motor only, not a complete pump. It is a square flange motor, which you can recognise by a square plate on the pump end with a bolt through each corner. It is a 56Y frame with a threaded shaft. It runs on 230V, two speed. It bolts to the wet end you already have, so the pump housing, impeller and plumbing stay where they are.

✅ Check these before you order

• Compare total horsepower, not nameplate horsepower. Multiply the horsepower on your old motor’s label by the service factor printed next to it. This one is 1.3 HP total. Two motors labelled differently can be the same motor once you do that sum.
• Mounting. Square flange, C-face and thru-bolt motors are not interchangeable and there is no adapter between them, so check yours matches before ordering.
• Frame size. Measure across the round body of the motor: roughly 5-1/2 to 5-7/8 inches is a 48 frame, roughly 6-1/2 to 6-3/4 inches is a 56 frame. Measuring beats reading the old label, because some makers labelled 48 frame motors as 56. This one is a 56Y frame.
• Shaft. This motor has a threaded shaft. A threaded shaft has the impeller screwed straight onto it; a keyed shaft is smooth with a groove down it. The two are not interchangeable.
• Voltage. This motor is 230V. Read it off the old motor’s label rather than assuming from the wiring – a spa wired for 240V can still run a 120V pump.
• Height. The capacitor sits in a raised hump on top of this motor, so measure your clearance if it sits under a spa skirt or below low plumbing.

🔧 When you fit it

• Fit a new shaft seal at the same time. A failed shaft seal lets water into the motor and is the most common reason a motor dies. Reusing the old one on a new motor is the quickest way to ruin it.
• Rotation. Pool and spa motors turn counter-clockwise seen from the shaft end, shown on the label as CCW or CCWPE. They cannot be reversed by swapping wires, so check the old label if it says anything different.
• Keep the horsepower the same unless you are changing the impeller too – the impeller is matched to the motor’s output.
