I have this B229SE pump. 5 years ago the pool pump was squealing so the repair guy rebuilt my pump motor and increased the HP from 1 HP to 1.5 HP. I dont know if the impeller was replaced. I have felt that the filtration system de2420 never seemed great, so I have replaced that filter with the hayward de6020. Now this pump motor is loud this year and I want a replacement. What would you recommend as a motor with this larger filter and would I need to replace the impeller?

A  Answered on 5/25/2019 by InyoPools Product Specialist Patrick P.

Hi DD, Could you give us the pump make and model information, common pump names would be Pentair Whisperflo, Pentair Challenger, Jandy Stealth, etc.. To supply this information click the reply link below, also if you could send a few photos those are always helpful as well. If you send photos then take a close up shot of the motor label as well as a wide shot of the complete pump to include the pipes going in and out of the pump. To supply photos simply click the reply link below and upload your photos. Once we get any of this information we can make the proper recommendation. It would also be important to know if the impeller was changed, ideally if you could pull a part # off of the impeller that would be very helpful. Here is a guide which would show you How to Acess the Impeller there should be a part # embossed in the impeller and that is what we would need.

Is your pump B229SE (photo 1) a suitable replacement for my old SP1610-Z-1-MBK (photo 2)? If so, can you supply it with the impeller etc installed?


A  Answered on 5/20/2019 by InyoPools Product Specialist Hector F.

Yes that motor is a another replacement option. You can also use the UST1152.  

?     Asked on 5/15/2019 by William

A  Answered on 5/15/2019 by InyoPools Product Specialist Hector F.

?     Asked on 4/20/2019 by Jeremy

I currently have a 1 HP frame is 56j B228se century motor and it just died. My pool is approximately 20,000 gallons. The motor before it died didn't really circulate the water very well in the pool and we had dead spots. So my question is. If i upgrade to the 1.5 hp motor is it the same size as the 1hp version, just with a higher water flow? Will it fit?


A  Answered on 4/20/2019 by InyoPools Product Specialist Lennox H.

Hi, Jeremy. Increasing the motor size without changing the internal pump parts like the Impeller and diffuser will not increase the water flow. If your pool has dead spots, you will need to reposition your jets to maximize circulation. You will need to make sure that your filter is large enough to handle the additional water flow. This B229SE will work. Check out our How to Size a Pool Pump guide. 

?     Asked on 3/30/2019 by Chuck

Ok, here are the photos - as you can see it has a lot more bolts than the one displayed here.


A  Answered on 3/30/2019 by InyoPools Product Specialist Lennox H.

Hi, Chuck. This motor is mounted to the Motor Clamp 2000 Series Astral - 23372-0001, the other components are attached then attached to the Strainer. For a complete breakdown, check out the Astral Sprint 2000 Series (Sprint) Parts Diagram.  

?     Asked on 2/22/2019 by charles

do i need a seal kit with this motor ?

A  Answered on 2/25/2019 by InyoPools Product Specialist Hector F.

It is always recommended to replace the seals and gaskets with every motor replacement. You will need to know the model number of the pump housing that the motor actually bolts to in order to cross-reference that. If you do not have that information you can always email us images of that housing to upload@inyopools.com so we can assist in locating that information for you.

Can you tell me the difference between the PL1152 and B229SE pool motors? I believe they both have the same applications as far as pool pump compatibility is concerned.

A  Answered on 1/31/2019 by InyoPools Product Specialist Steve M.

Rich, you are correct the PL1152 and the B229SE are the same motor and function the same. The PL1152 is our house brand motor. We manufacture it in house. The B229SE is made by AO Smith. Those are the only real differences.  

?     Asked on 1/28/2019 by Chuck

My pump is identified as a Y56J Frame, F 1.00, HP 1.5, Part 7-184982-23, Cat B229Se, Type CX, RPM 3450 It has eight (8) mounting bolts instead of four (4) - this seems as if it would be a problem. How do I resolve this issue?


A  Answered on 1/29/2019 by InyoPools Product Specialist Patrick P.

Hi Chuck, Could you take a few additional photos? A wide shot showing the side view of the pump as well as any labels showing the manufacturer and model name of the pump. To add the photos click on the reply link and then there is a button to add photos.

I have a Hayward SP3010X15AZ pump housing. The pump I need to replace is a 5KCR39SN2823AX. Will this pump fit ? Also what else do I need to purchase? I;m sure I will need a seal kit but what about the capacitor like the one on my old one.Or is this motor ready to go out of the box ?

A  Answered on 10/30/2018 by InyoPools Product Specialist Hector F.

The replacement motor would the model UCT1152 and it is recommended to replace the seals and gaskets. For that pump in a chlorine pool the kit is a GOKIT2 and for a saltwater pool, it is the GOKIT2SALT. The capacitor is already in the motor.

Is this the same moter for a jucuzzi pool pump. This is what I have on there now. Cat B229SE Serial CB05-09 Part 7-184982-23 Volts 230/115 Amps 7.2/14 The motor I have now got hot and now it doesn't work.it was running fine this morning.not sure what happened.now it just hums when turned on.

A  Answered on 6/28/2018 by InyoPools Product Specialist Hector F.

If the model and part number that you have provided has been on the pump for years then yes this is the replacement. If it is brand new and has gone bad then it may have been the incorrect one put on there and you would want to locate the model of the complete Jacuzzi pump to confirm. 

?     Asked on 5/26/2018 by Whitney

Since this motor does not come with the capacitor on top can we just remove the capacitor from the old motor and install it on this one? Or can you tell me what run capacitor I need to order for this motor? Thanks.

A  Answered on 5/26/2018 by InyoPools Product Specialist Lennox H.

Hi, Whitney. You cannot install a capacitor on this motor. This motor uses the 25 MFD 370 VAC Run Capacitor - 628318-307

will this work on a haywood pump

A  Answered on 5/16/2018 by InyoPools Product Specialist Andy O.

Hello Jerry- The Motor 56j Thrd Up 1.5 Hp (b229se) 5212x does fit some Hayward pump models, if you can provide the model of your pump we can confirm that this motor is what you need as well as recommend a shaft seal.

Will this work for a Jandy PHPU1.5 pool pump?

A  Answered on 8/26/2017 by InyoPools Product Specialist Lennox H.

Hi, Derek Kraese. Yes, this motor will operate the Jandy PHPU1.5 Pump. 

?     Asked on 6/15/2017 by Chris

I ordered a 5212X motor to replace the motor on my Jandy JHPU 1.5HP pump today which I think is the correct motor. I noted that your 5212X motor drawing shows that it is a CW rotation. My existing motor as viewed looking at the impeller end of the shaft rotates in a CCW manner. Did I order the incorrect motor ? Thanks.

A  Answered on 6/25/2017 by InyoPools Product Specialist Lennox H.

Hi, Chris. This B229SE motor is the correct replacement motor for the JHPU1.5 Pump.

?     Asked on 4/29/2017 by

what seal do I need for this pump replacement

A  Answered on 4/29/2017 by InyoPools Product Specialist Lennox H.

Hi. In order to locate the correct seal for your pump, we will need to know the pump housing model. If you're unable to locate the pump housing model you can email us photos of the housing so that we can identify it.

?     Asked on 4/5/2017 by Dan Price

This shows to replace my Jandy JHPU 1.5 (part # 7-193632-24) but the motor I have has a capacitor on top. This is shown on the detail drawing, but not shown in the photo. Does this motor come with the capacitor?

A  Answered on 4/5/2017 by InyoPools Product Specialist Andy O.

Hello Dan- the Motor 56j Thrd Up 1.5 Hp (b229se) 5212x would be the replacement motor you will need. There is no capacitor on top of this replacement motor.

?     Asked on 5/12/2016 by

Hi, How do we tell which seals to purchase with this replacement motor? There is not a label on the front housing.

A  Answered on 5/12/2016 by InyoPools Product Specialist Andy O.

Hello- The seals will be based off of the model of the pump not the motor. If you can not find a label on the front housing we would need to see if we can find a part number on the impeller or pump lid to try to identify the pump. If not you can send a picture to upload@inyopools.com.

What is Service Factor?

A  Answered on 1/11/2012 by InyoPools Product Specialist Patrick P.

Service Factor(SF) is a multiplier that when multiplied by the horsepower of the motor indicates the total permissible horsepower loading that may be carried when the motor is operating at rated voltage and frequency. The most important thing to remember when replacing a motor is that the replacement motor's horsepower times its service factor must be equal to or greater than the original motor's horsepower times its service factor. The Service Factor rating can be found on the motor label. See Step 4 of our How to Read a Pool Motor Label guide.

Existing pool pump failed after 12 years of operation

Written on 6/29/2017 by Guest

My pump was a 2005 Jandy JHPU 1.5 HP unit.

1, Turned power off to the pump control panel
2. Opened suction basket lid and vented filter housing to drain system back to inground pool
3. Removed 6 pump flange bolts and pulled pump/motor assembly from pump body
4. Noted 1 diffuser flange screw missing and the other loose due to both brass thread inserts corroded away in mounting plate assembly. Removed diffuser and cone from mounting plate.
5. removed motor end cap to access shaft wrench flat.
6. put wrench on flats to hold shaft still and removed Left Hand thread impeller lock screw
7. removed Right Hand threaded impeller from motor shaft
8. removed 4 bolts holding mounting plate to motor, then removed mounting plate from motor
9. turned power to the pump panel back on, closed the motor breakers then turned on the motor to check.
10. motor sounded like it had gravel in it and tripped on motor overload heater after approx. 20 seconds. So I knew my motor was bad, then disconnected the power again. Since the motor was 12 years old and showed obvious signs of deterioration, I looked for a replacement motor.
11. found what I needed on INYO Pools website, asked a couple of questions and got confirmation that motor replacement was correct for what I had and then made the purchase.
12. ordered up new seals, mounting plate and diffuser plate w/cone along with the new motor and reversed the disassembly.
13. to make the installation easier, I purchased new wire, conduit, fittings and connectors and wired up the motor & put the pump assembly together on the bench where it was easy to work.
14. carried the assembly with the 6 foot conduit and wiring all connected to the motor out to where the pool equipment was,
15. made the electrical connections in the control panel & bonding wires, bumped the motor to verify correct rotation, turned the power back off then installed the pump with new gasket into the pump housing.
16. primed the system and turned the power back on & started it up, checked for leaks and I am now one happy camper thanks to the folks at INYO. Motor is quiet and runs like a champ.
17. purchased a motor cover from the local pool supply store and installed over the motor to protect it from the weather as the installation instructions recommended.

Were these instructions helpful?

Bearing went bad and I took motor apart & saw salt water leaked by the seal plate so I replaced the motor seal kit,Defuser and impeller and seals

Written on 3/18/2017 by Guest

I removed the motor and all attachments on the front of motor , Seal plate, difuser, impeller and seals and replaced all of them with new ones after watching several of the INYO videos on how to replace each one. The video's really helped and made the replacement pretty easy.
