Today's pool pump motors are much more efficient. If you have an older pool pump or it's motor is running loud or just stop working, you'll want to consider replacing your pool pump motor. You do not have to replace the whole pool pump and as this guide will show, replacing your pool pump motor is not difficult. Although this guide is specific to a Hayward pool pump, most of the steps can apply to other models of pool pumps. Caution: You must ensure that the electrical supply agrees with the motor's voltage, phase, and cycle and that all electrical wiring conforms to local codes and NEC regulations. If you are unsure of this voltage or are unfamiliar with electrical codes and regulations, have an electrician wire your pump for you. Failure to wire the pump correctly can cause electrical shock or can damage your pool pump motor and void your warranty.

In hooking up a motor to the timer...the motor has three wires, green for ground, and two red leads to be hooked up to the timer. The timer has 5 terminals, 1 for common, Line 1, Load 1, Line 2 and Load 2. I want to hook up my two red leads to the timer. Where do they go? Line 1 and Line 2 ? Or What are the two Load lines for? Please elaborate for me.Reply
Jay Posted: 6/29/2015
I am replacing the motor and noticed a red wire from a micro switch from the top side of the timer came off the terminal...My problem is i don't know which lead it came off from? One is still on a terminal but other is just hanging close by...Which lead would it connect to?Does it matter which red wire goes to whatever terminal on the timer? The motor has three wires to connect...green for ground, red hot and other red for hot...do the red wired connect to Line 1, and Line 2? on the clock terminal? or does it matter?

Gill - Two possibilities: Can you replace the bonding lug? - unscrew the old one off the motor or relocated it to another hole on the motor. Or is there enough of a stub of wire where it was cut off that you could clamp the bonding wire on to with a split bolt. See "How To Add a Line to the Pool Bonding Wire".Reply
Gill Posted: 6/22/2015
This seems pretty straightforward, the pictures help greatly. One thing I noticed, the bonding lug on my pump is rusted up tight (WD-40 was useless). I was able to cut the bonding wire very close to the bonding lug in order to get it worked on, but a a piece of the wire is now stuck in the lug. How would you recommend safely reconnecting?Reply

Rob - See Step 30 of our guide on "How to Replace a Single Speed Motor with a 2Green Motor". One wire will go to L1, the other to L2.Reply
Rob Posted: 5/15/2015
Hi, replacing my motor with the 2Green 2 speed. I had a single speed motor with all the same specs as the new one. My old motor had the red wire hooked up to the A terminal and the black wire hooked to the B terminal. This new motor has an A terminal, L1 and L2. Does the red wire go to A and the black to either L1 or L2?Thanks, Rob

beachin - Not sure why this isn't fitting. Both motors have the same frame, 56J, and we show the new motor being ~1/3 of an inch shorter. old SP1610Z1 = 13.35 and new B2977 = 13.03. Incidentally, your new motor is a 2-speed and the recommended equivalent 2-speed motor for this Hayward Northstar pump is SPX1610Z2MNS.Reply

I am replacing a B2977 motor on Hayward Sp4010NS from a SP1610Z1. The new motor is longer and having trouble getting it to go into the motor assembly. It won't fit. Any help please... ThanksReply

Bought my motor last fall when the other one died and finally got around to replacing it once all the snow melted. Followed these instructions and had no problems. It was nice to have the gasket and seal kit that was recommended. Total time to replace and turn on was 2-3 hours. Thanks.Reply

Dave L - You should not run your pump with the motor unsupported. Generally pumps are sold with an insert for the mount so that you can add it to support a smaller motor. See if your mount has an inset added to it that you can remove to accommodate the larger diameter motor. If this doesn't work, see if you can buy a separate replaceable mount that can attach to the bottom of the pump.Reply

I have a Sta-Rite Dyna-Glas 1.5 HP motor I'm replacing on a Sta-Rite Pump. I got a new 1.5 HP US Motor at the pool store and all went great until I tried to install it on the pump. The diameter of the new motor is larger and won't fit in the pump's stand. What do I do, Cut the stand apart, discard the stand under the motor, install the motor and let it hang off the pump?Reply

CCWPE - You are correct. The impeller is screwed on clockwise when viewed from the pump end, and the pump will rotate in a counter-clockwise direction when viewed from the pump end. I have no answer for how your impeller came off. An AC motor like these cannot be wired to reverse in the wrong direction. When the motor is in rotating, it will be tighten the impeller onto the shaft.Reply
Anonymous Posted: 11/23/2014
Which direction should a Hayward Super Pump 2HP rotate - Clockwise or Counterclockwise? I replaced the impeller and noticed that you screw it on clockwise but the motor rotates counterclockwise and the impeller spun off and damaged the defuser.Reply

Great Video! I watched this on and off all day today as I sucessfully changed my pump. I noted the comments of check the wiring so I did a foto before to examen. I am not the most mechanical but your video stepped me through, I had a Pentair wisper which is slightly different, but you still got me Though! AWESOME!Reply

Jill,Check the power at the motor with a meter to make sure you are getting power to the motor. Make sure that the supply power matches how you have set up you motor. If you have 115V coming from the breaker box, make sure that your motor is set up for 115V. Make sure your wires are tight on the motor terminals.

overheated motor - Check to make sure that the supply voltage to your pump matches the voltage your pump is set for. If you are operating off an extension code ,l make sure it is heavy enough to carry the current to your pump. See our guide, "How To Troubleshoot a Pool Pump Motor - Motor Overheated", for other possible causes.Reply

I replaced my motor pump and hooked all the wires up (2 were red and one green for ground) I put everything back together and it started fine but after about 10-15 minutes it shut down and was very hot to touch. I let it cool and it started again but shut down when it got hot again. any ideas why this happened?? ThanksReply

Springhill - By circular pattern do you mean 1,2,3,4,5,6 or are you tightening the bolts as 1,3,5,2,4,6 as we recommend? Are any of your bolts stripped? Do they all screw down tightly? Look for any breaks or scratches in the seal plate or housing edge. Make sure the surfaces that come together are clean and smooth.Reply

We use 3 Hayward Super2 pumps for our 2 pools. I've rebuilt all 3 with good success except on 2 of them when I put the motor assembly (impellar & diffuser) back onto the pump housing they will leak around the flat seal.I've tried installing it both vertically with the pump housing down to not force the joining and horizontally. Then tightening the bolts down in a circular pattern to allow even pressure on the seal. They just always leak and as the pump settles in the leak slows down or actually stops as if it's settling in but according to the flow meter the gpm increases?Reply

nancy - It may mean that your current impeller is too large for your replacement motor when it is operating at full speed. You may have to replace your impeller with a smaller one.Reply

what does error code 12 (on a go-green replacement motor) mean when replacing a hayward motor on an inground pool pump made by a.o. smith?Reply

RAY - If it's sounding bad - grinding - and overheats, it's probably time to replace the motor.Reply
RAY Posted: 5/27/2014
My 1 HP pool motor was tripping the breaker, so I tapped motor with a rubber mallet and the motor is running, but it is still over heating after a few hours and not sounding right. Should I just replace the motor?Reply

I've been in a quandry trying to replace the seals on my Max E-Glas II pump. Sta-rite has been sold to and I have a time getting the right seals (Max E-Glas II)which seems to be sold out in my area. On top of that, I have broken the v-shaped carbon switch over the rotating switch. Can it be replaced and what is it called?Reply

Booster Pump replacement - Unfortunately we do not have a guide yet on replacing a Booster Pump Motor. You could use this guide generally for replacing a motor, but there will be specific differences between this motor and a Booster Pump Motor.Reply

Ian - It sounds like your motor's bearings are going but I would check your impeller first to make sure it isn't loose and wobbling or isn't clogged with debris. See our guide on "How To Replace A Pool Pump Impeller" for more information.Reply

I have an intermittent squeal coming from my 1HP Hayward/AOSmith self priming pool pump. Motor appears to be running OK and not getting hot. Any ideas of where the problem may lie? Do i need a new motor or is it more likely the diffuser / impeller assembly?Reply
JeffBG Posted: 11/10/2013
These instructions were very helpful. Unfortunately, after installing it and connecting my new Century 1.5 hp motor, it didn't start. The voltmeter verifies there is 115 volts going to each lead. Is there a reset button on the motor? What could be the problem?Reply
InyoPools Product Specialist Dennis R. Posted: 10/27/2013
Dirk Mc - With AC motors it does not matter which wire goes to L1 and L2. White or black can be connected to L1, the other to L2.Reply

I am replacing my 110V pump motor and the 2 wires are black and both show 110V when tested with a multimeter. Does it matter which wire goed to L1 and L2 ?Reply

L Knowlton - Check that your motor wire connections are tight, but if this is an older motor - 5 to 10 years, it might be time to replace it.Reply

Hi guys! Great step by step instructions. my hayward super pump 1hp keeps tripping the circuit breaker each morning when i go to turn the pump on. I have to reset 5-10X! We have installed a new circuit breaker, new outdoor outlet and it hasnt nelped. Getting ready to replace the motor on the pump. Any other ideas before we do this? ThanksReply
InyoPools Product Specialist Dennis R. Posted: 7/15/2013
stuck motor - If this is an older motor, it may have some corrosion between the motor and the housing. I would take a rubber mallet and tap it around the circumference of the motor to try to break up the corrosion.Reply

I am replacing the motor on a pentair superflo pump model cf-0039 (1.5 hp) With a centurion 1.5 motor. After taking off the 4 Bolts that connect the motor housing to the pump and draining the water out of the pump, I cannot pull the motor housing away from the pump. Do you have any suggestions as to what is happening and how to pull the housing off?Reply
