A.O. Smith Centurion replacement motor for Pentair WhisperFlo and Challenger full rated pumps. Specifications: HP = 1, RPM = 3450, Voltage = 115/230, Amps = 16.0/8.0, Service Factor = 1.65, Frame = 56Y, Shaft = Threaded. *Please Note: This is the correct replacement motor for the Challenger 1 HP full-rated pump.
Can. This fit my sta rite 3\4 pump
Yes, that motor will fit but you need to make sure your filter is able to handle the increased flow rate from that motor. The total horsepower on the B848 is 1.65 so it would almost be a full horsepower more than the .75HP
I have a pump with howling bearings part# 7-177474-01 frame P56Y I think it is 1 1/2 hp but does not list on label. I am considering adding solar heating panels and want to know if it is advisable or even possible to up-size to a higher hp pump motor?
Hi Kelly, The part number 7-177474-01 is a 1 HP motor which is the B853. Depending on how many solar panels and the height you can increase the pump motor.
I have a Centurion Switchless Motor No Switch No Governor 2514514-001. This is the only information I see on the motor and it's hooked to a Pentair Whisperflo. Which one do I buy?
Hi, Without the part, cat or mod number from off of the motor the only other way to determine which motor you'll need is to provide the part number off of the impeller.
will this motor work with pentair sf-n1-1a/340038 pump? the motor Model # I now have is 196238. And what seal kit if this motor will work please. thanks Phil
Looking for a replacement motor for a Pentair Whisperflow. Unit says it is a 1.5 HP 1.10 SF making it 1.65 HP. The part number appears to be either 7-177475-20 or 7-177475-28. Concerned about my motor burning quickly (5-6 yrs) and want to keep the expense down. Better to get higher or lower SF motor? What do you suggest? Also - I see various "tune-up" kits (gaskets, etc.) but have read some folks report the parts were incorrect in the kit. Need recommendation based on your motor suggestion.
what seal part number for this motor - thank you!
I'll need to know the model of your pump, not your motor, to know which seal kit you'll need.
Besides the Centurion pool pump B2841, B2848, are there any other parts that replace the 7-177080-24?
Hi, The B2481 and B2848 are the only single speed replacement for the 7-177080-24 motor.
I have a super pump Hayward by c.o smith and in need of a new pump motor. it is square with capacitor on top. I cannot find the exact same manufact # for a replacement? can you help.
Hi Karen, could you email us some photo's of your pump as well as a close up photo of your motor label. This would help us identify the correct replacement motor for you.
Does this motor work with the PAC fan challenger pump? Does it come with a shaft seal?
Yes, this motor is compatible with the Pentair Challenger pump. The shafts seal is not included with this motor; the correct pump shaft seal for the Challenger is the PSR-200
is this the same as Pentair Part 7-177450-03? How many HP is this motor?
Hi Jeff, This B848 motor can work as a replacement but the B2841 which is an energy efficient and the exact replacement to your motor has a total hp of 1.65.
i need a filter cover for a J O Smith 1 HP centurian pump code j form kjm. it is about 12 years old. is that available
Sam, do you mean the strainer lid of your pump housing If so I need the model number of the pump housing. The pump housing is the plastic hull that the motor connects to.
Can this motor be used on a boat lift?
Charles, Unfortunately this motor is only designed for pool and spa applications.
Does it work on Jandy pump?
Hi Tim, This motor can work on a Jandy Pumps.
Would this pump be a suitable replacement for my Pentair 355022S?
Hi Gary, This motor will replace the Pentair 355022S OEM motor.
I am looking to replace my current pool pump motor Century Centurion HP 1.0 (B2848) frame Y56Y. Is there a more efficient alternative replacement motor available in the same exact size. Also, do I need to order anything else in addition to the motor? Just a rookie at this. Many thanks, Lou
Hi Lou, The B2841 is the energy efficient replacement to the B2848 motor. We also recommend replacing the pump shaft seal and or pump o-rings.
Will this fit my 7-193993-05? If so other seals do I need.
Hi Nick, This motor can also be used in place of p/n 7-193993-05, however p/n B841 would be an energy efficient replacement. If you can provide us with the manufacture and model of the pump we can locate the seal for that pump.
is this the correct pump to replace a AO.Smith 193993, Frame Y56Y
Yes this a replacement motor that you can use. You can also use a more energy efficient single speed being the model B841.
Is this the correct replacement motor for a Pentair WhisperFlo WF-4 and does it come in almond / cream color? The markings on the old pump are as follows: Part 7 -177475-20, FR Y56Y, Type CX, Form KJM Serial CB07-11 1081 pool pump duty mount horiz with vent holes down cust P/N 75234
My current motor is a Pentair 177475-20 which is supposed to be compatible with this motor. All the specs are the same though this is listed as a 1hp instead of the 1.5hp of the Pentair. Am I correct that the shaft of this will work with the impeller of the Pentair Superflo pump that uses the 1.5hp impeller?
Hello Roger, The B848 1 HP Standard Motor - Full Rate (B2848) will replace your current A.O. Smith motor. The 177475-20 comes up as a 1 hp full-rate or 1.5hp up-rate. This 1 hp full rate has a total HP of 1.65 which makes it identical to a 1hp up-rate. This motor can be used on a superflo with no problems.
Hi, I have a AO Smith 1HP motor with part number 0196255-0, this looks like the right on, please advise if this is the correct part, and should i buy the shaft seal kit and gaskets
Hi Leigh, We would need to know the manufacture and model of the pump housing that this motor connects too in order to get you the shaft seal, o-rings and or gaskets.
Hello- I have a 1.5HP Jandy Stealth pool pump that is starting to make loud noises when on. If I need to replace the pump motor, would this be the correct part? My part # is 7-193993-05. Thanks!
Hi Mike, The A.O. Smith 1 HP Standard Full Rate Motor (B2848) will be the correct replacement motor for p/n 7-193993-05.
I am trying to find a replacement for my century centurion ao smith part 0-193986-24. Is this part compatible?
Hi Brandon, The A.O. Smith 1 HP Standard Full Rate Motor (B2848) is compatible with p/n 0-193986-24.
I am trying to replace my US Motors pump B63GZAAP-1013. 1.0HP, 1.65 SF 3450/1725 RPM, 56Y. I understand this is a single speed in comparison, but will this work? Which model is the two speed replacement? Thank you!
Hi Nancy, The A.O. Smith 1 HP Full Rate Square Flange Dual Speed w/ Digital Controller (B2982T) will be the correct replacement motor.
I need a replacement for my AO Smith B2853 Part 7-F56AA37A01-04
Justin,The replacement for motor # 7-F56AA37A01-04 is B853. You can confirm by simply typing the part # into our search engine. Don't forget to purchase a new shaft seal when you replace your motor.
What pump motor will replace my Magnetek PN 10-165199-10?
Hi Milton, The A.O. Smith 1 HP EE - Full Rate Motor (B2841) would be the correct replacement motor for the Magnetek P/N 10-165199-10.
I need a replacement for a century by A.O.. Smith B2848 part #7-196261-24 1 hp type cx code j is this the motor. The last time I needed one I had to send back because of shaft lenth
Lu- This motor is going to be an exact replacement for your B2848 motor that you currently have.
Is this the replacement for my current B848, PN: 7-177080-24? Thanks!
Hi David, The A.O. Smith 1 HP Standard Motor - Full Rate (B2848) will be the correct replacement for the B848/7-177080-24 motor.
Good morning. I need to replace my current motor which is a Century Centurion 1 HP part number 177450. Please advise what motor you recommend. Thank you.
Hi Denise, The A.O. Smith 1 HP Motor EE - Full Rate (B2841) would be the correct motor that will replace p/n 177450.
I need a replacement motor. My currently broken motor is a Century Centurion part number 0-177897-22. What motor or motors could replace that?
Hi John, The A.O. Smith 2 HP, 56Y Frame, Up-Rate Motor (B855) will be the correct replacement motor for p/n 0-177897-22.
I need replacement motor for pentair part #0-177474-01. It looks to be the B2848. Is this correct and do you have in almond color?
Hi Mark, The A.O. Smith 3/4 HP Standard Motor - Full Rate (B2847) would be the correct motor that will replace p/n 0-177474-01. The 3/4 HP Full Rate/ 1HP Up Rate Single Speed Motor Almond would be the OEM motor.
I believe this is the correct replacement for my Magnatetek Century Centurion part # 7-177450-03, all other nomenclature matches, y56y frame, 230/115V. This is paired with a Whisperflow WFE-4 pump. I added solar thermal panels 6 months ago and all has been fine until the motor recently seized, my question is do I need a bigger pump/motor to push the water to the roof, is that possibly why the 10 year old motor failed? Also please recommend the gasket kit for this pump.
This is a correct motor replacement for you. 10 years is a good life span for a motor. On average a total horse power of approximately 1.5 as this motor has, is good enough for a solar system. The seal kit for the Whisperflo on a regular chlorine pool is the gokit32 and the salt water version is the gokit32salt.
Does this motor come wired 230v, as a standard, from the factory?
Hi Dave, The 1 HP Standard Motor - Full Rate (B2848) does come set for 230 volt connection from the factory.
I have a Pentair Whisperflo WF-4, motor #177475, that needs replacing. If I buy the Centurion replacement, what seals,etc, do I need to purchase?
Hi ya! I'm going to be replacing a centurion 8-168453-24 1 hp motor. Is there a variable speed pump/motor that would be more efficient? I have a Hayward pro series S220T sand filter rated at 52 GPM. Many thanks...D
Hello dee the ECM16SQU 1.65 HP Variable Speed Pool Pump Motor Square Flange would be your variable speed option
I need to buy a replacement motor for my Jandy Stealth SHPF 1.0. I know the B2848 is correct as that's what I have now, but in reading previous Q&A there are seals/gaskets/o-rings that need to be replaced when swapping out the motor. It seems like I need a Jandy GoKit based on responses to prior questions but I did not see a Jandy GoKit listed on the site. Can you post links to all of the recommended replacement seals/gaskets/o-rings for my pump when a motor is replaced? Thanks
Scott,Unfortunately, the Jandy Stealths do not have a tune up kit. You have to purchase all the seals separately. The mfg recommends replacing at least your shaft seal whenever you replace your motor. You can find all your Jandy SHPF replacement parts here.
I have a WhisperFlo WF-24 pump with a one-hp motor that the previous owner installed. The motor has always operated so hot that I couldn't touch it, and the motor has just burned out. Is this the correct motor as replacement?
This seems to be the proper motor for a Pentair Challenger 1 HP. However, it is a "56 frame", while the one that just died is a 48 frame SQ1102(we bought the house 3 years ago, the pool is about 13 years old, I guess the motor was replaced already). Would this 56-frame motor fit, or should I just replace with the exact same motor (SQ1102)? Thanks. your site is awesome, by the way....
Usually the 56 frame style motors were originally used on the Challenger models so I would go with the B848. Functionally though, they both can work.
I have an Pentair Intelliflo VF so what parts would I have to swap out(Impeller, diffuser,kit,) to do a motor replacement with this one please? Also, what is the impeller screw I need for this and is it the same size as the Intelliflo impeller screw? Thx.
The impeller part number that you would need is 5074-27c and the diffuser part number you'd need is 5074-13a. The impeller screws are exatly the same being part number 5074-14.
my 5 yr old Pentair dynamo motor runs hot, sometimes almost too hot to touch. Is this normal or is the motor on it's last leg?
Ron - Motors do run hot especially in a hot climate. But there are conditions that make them run hotter than they should. See our guide on "How To Troubleshoot a Pool Pump Motor - Motor Overheated" for more information
I have a very old, 30+ years, Anthony Antho-Sweep A.O. Smith pump, model number (best I can read it) C48K2EBJ02, Frame 48Y. Would this pump work as a replacement. I know this one is a 56Y frame but I'm reading in some places these might be usable to replace a 48Y?
The motors can be 56Y and 48Y swapped with no problem. The difference between the 56Y and the 48Y motor is the width of the barrel, the 56Y motor is wider then the 48Y motor. Sometimes when going from a 48Y to a 56Y, the base has to be cut to fit the larger motor.
How do you remove the black fan that moves the water from the pump
Hi Lee attached is a how to for the impeller
I see that this is a replacement for the Centurion 7-177475-20 motor, which I have on an Ultra-Flow pump, and is a 1 hp rated motor replacing a 1.5 uprated motor. What would happen if I put the 1.5 full rated (B2854) motor on my pump?
Tom, Aside fromt he higher horse power motor costing more to operate, you will not see any added benefit unless the impeller is upgraded as well.
I have the whisperflo wf-26 pump with pentair motor 7-177475-20. Is this the correct replacement? Thanks
The B848 1 HP full rate motor for your WF-26 pump. We would also suggest the replacing the Shaft seal on your WF-26 pump as many times if you use your old shaft seal you will have leaking which will cause damage to the new motor. A leaking shaft seal will also void the motor's warranty.
My pump motor has part #7-168453. It shows to be a 1 1/2 HP Centurion, type CX, code J. Is this the correct replacement motor?
Hi Dennis, Yes this would be the correct replacement for your 7-168453 motor. The reason this motor shows 1 HP and yours shows 1-1/2 HP is that this motor is a full rate motor and your motor is an uprate motor and a 1 HP full rate motor is identical to a 1-1/2 HP uprate motor. So you should be all set with going with this B848 motor.
Does this motor ship with capacitor installed or does that have to be purchased separately ?
Hello Mark - The motor ships with the capacitor already installed.
my 1hp Magnetek motor (8-177080-24 230/155volt Y56Y SF1.65) made a scrapping high pitched noise the other day that only Rosanne Barr would have appreciated...so i turned it off. The next day there was just a humming sound. A buddy and i opened the motor, cleaned it, replaced the bearings and now ready to reattach it to the pump but want to get the correct seals and gaskets. The pump is cast iron with what looks like engraved on the strainer body, C3-29D on its lid and 01-63DA on the pump.
Hi Jeff, I can confirm that this is the proper replacement motor for your Magnetek 8-177080-24 motor. For the seals and gaskets I would need to know your pool pump manufacture name and model # as I was unable to cross reference any of the part #'s you supplied. Based on the part #'s you supplied I believe this is most likely a Sta-Rite pump, model names for Sta-Rite would be Max-E-Glas, Max-E-Glas II, Dura-Glas, Dura-Glas II, C Series, CC series, etc.. Also is the strainer housing plastic, cast iron or bronze? Please email us back with this information and/or any pictures of your pump, as this will help us determine the needed seals and gaskets.
My part # is 7-193993-05 is this the right motor for replacement? my pump model is SHPF 1.0
Hi Craig, Yes this would be the correct replacement motor for your 7-193993-05 motor being used on your Jandy SHPF 1.0 pump. We would also suggest the replacing the Shaft seal on your Jandy SHPF 1.0 pump as many times if you use your old shaft seal you will have leaking which will cause damage to the new motor. A leaking shaft seal will also void the motor's warranty.
I have a Jandy pool pump system. The pump motor is making noises. It is an A.O. Smith 1.5HP part number 7-193986-24. Also, what seals would you recommend replacing?
The correct replacement for your motor is model B854. The seals would depend on your Jandy model (Plus HP, Max HP, Stealth, WTFR, or Flo Pro). You can find the replacement seals on those part pages. I would recommend replacing the shaft seal, diffuser o-ring, and backplate o-ring.
I am shopping for a new pool pump motor (mine is starting to make noise). I now have a Pentair 0-177450-3 1HP motor and looking to replace it with the B848 motor. Will I have to have a different shaft seal for my Whisperflo WFE-4 pool pump?
Hello Wade - You could replace your current motor with the B848. The shaft seal would be the same regardless of the motor.
What is the difference between the B2841 and B2848 motors?
The difference between the B848 and the B841 is the amps it takes to run them. They are both Energy Efficient motors and both have a Total Horse Power ( horse power times service factor ) of 1.65 hp. The B841 is just slightly more efficient by running at an amp usage of 7.4-7.8 at 115v or 14.8 at 230v. The B848 will run at 8 amps at 115v and 16 amps at 230v.
Is the B848 pool pump motor suitable for outdoor pool pumps?
Yes, this motor will work just fine for either indoor or outdoor applications. The motor is determined by the wet end that it is being attached too. A motor cover is recommended for outdoor use to protect from rain, sprinklers and the runoff from the roof, rusting the motor prematurely.
Will this motor (B2848) fit a Whisperflo model WFE-4 pool pump?
Yes, the B848 motor will fit the Pentair Whisperflo WFE-4 pump.
Will this replace a 208-230-115 volt motor?
The specs for motor B848 are indeed compatible with a 230 / 115 volt motor.
The current pump motor I have is the AO Smith 7-177475-28 1HP. As I understand it, the B2848 can be used as a replacement. Can you please verify before I complete my order?
Hello Terry - The B2848 (B848) is the correct replacement motor for the 1HP part number 7-177475-28.
I have a Centurion Switchless Motor B668 HP 3/4. What one do you recommend?
We do still carry the B668 pool motor and this would be the motor we would suggest.
I just finished replacing the shaft seal on my booster pump. As soon as I turned the pump on water was leaking from the shaft seal. Is it defective or am I doing something wrong?
Depending on the model, the installation of a booster pump shaft seal can be slightly different than a pool pump shaft seal. Some booster pump and pool pump shaft seals require that a silicone sealant be used on the outer areas of the metal seat of the shaft seal. The seal will need to be lightly hammered into the body of the pump. You can use a 1 inch PVC coupling or a piece of 1 1/4 inch PVC pipe and a rubber mallet. This procedure will apply to any pool pump or booster pump using a >PS-1000 style shaft seal.
I'm trying to replace the motor on my pool pump but all these numbers and abbreviations on the motor label are really confusing me. What do they mean?
Replacing a pool pump motor is not as difficult as it seems. You can try looking here. If you need help figuring out what the information on your label means. If you are still having difficulty figuring it out you can call us at our toll free number or you can send us a photo of your motor label here.
Why should I purchase a Tune Up Kit?
A Tune Up Kit includes all of the essential replacement seals and gaskets for the pump. The seals and gaskets should be replaced when installing a new motor on your pump. New seals will prevent the pump from leaking water or losing the prime. A Tune Up Kit will protect your motor and ensure that the pump is working efficiently.
Why do I need to purchase a new shaft seal?
We strongly recommend replacing the shaft seal. The purpose of a shaft seal is to prevent water from running down the shaft of the motor and into the motor housing. Water will damage the bearings and cause the motor to fail. A new shaft seal should be installed whenever a motor is replaced. The motor manufacturer can deny the warranty if the motor fails to due to water damage from a faulty shaft seal. To find your shaft seal you will need to visit our Pool Pump Parts Page or the Spa Pump Parts Page and select your make and model.
What is Service Factor?
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.

(5 out of 5 stars) Pool Filter Motor
Reviewed By: DreamBigGoGreen from Bowie, Maryland ()
Pros: Customer service, shipping time, price and product
Cons: None that I can think of
Best of all is the wonderful customer service help provided by Inyopools. The product was here in the time specified and the price was considerably less than the 5 other companies I checked with first. The product was as specified and ordered and hasn't given me any problems to date. It was installed about a month ago.
