I just purchased my home and the pools pumps for the sheer decent is not working. Will this replacement pump work? Do I need to buy anything other than the pump?


A  Answered on 9/4/2019 by InyoPools Product Specialist Lennox H.

Hi, Corey. Yes, this B130 motor is the correct replacement. You will also need to get the Magnum Series Tune Up Kit - GOKIT14

Hi, I’m looking to replace this motor attached Hayward pump SP-3020X25. What kind of seal do I need? Will this require any other parts? Thanks, Alex


A  Answered on 7/31/2019 by InyoPools Product Specialist Matt S.

Your pump appears to be the old style Hayward Super II; the correct gasket kit is the GOKIT2 or the GOKIT2SALT.

I plan on purchasing the same Centurion motor which has a Serial# 13413CH and part #159988-06, Horse Power 2.0, Frame X56J, SF 10.5, CAT is B130. I think this picture on your website is the one, but it has a Serial# 26413CH. Is this the same as mine? My flange is round, it has a 'hump' and it says 'Switchless Motor' on the top. I'd sure appreciate any information before I purchase it from your company. Thanks! Laura

A  Answered on 5/29/2019 by InyoPools Product Specialist Steve M.

Laura, yes, your part number 159988-06 came back as a direct match for the Century Motors A.O. Smith 2 HP Round Flange 56J Full Rate EE Motor - B130. The A.O. Smith 2 HP Round Flange 56J Full Rate EE Motor - B130, would be the correct replacement. The serial numbers are unique to the individual motors and vary on every motor, as long as the rest of the specifications match than you have found your replacement.

I have this motor installed on what I believe is a Hayward SP4000L. The motor's bearings are going bad and I'm preparing to replace them so I'll at least need a shaft seal... Do you have a seal kit available for this pump? Thanks!


A  Answered on 4/1/2019 by InyoPools Product Specialist Patrick P.

Hi Marc, Thanks for the photo! You have a Hayward Northstar Pump and if your pump is from prior to 2003 then you will require this Hayward Northstar Shaft Seal Prior to 2003 and if your pump is from after 2003 then you will require this Hayward Northstar Shaft Seal After 2003. We also have the following Hayward Northstar Parts Schematics which you may find helpful for any other parts. Hayward Northstar Parts Schematic 1998 - 2007 and Hayward Northstar Parts Schematic After 2007

My 8-159988-06 is really noisy but runs. Unknown model Hayward pump. What bearings and seal kit would I need? Thank you!


A  Answered on 1/7/2019 by InyoPools Product Specialist Hector F.

The rear end bearing is part number 5270-31 and the front end bearing is part number is 5270-36. The seal kit for a chlorine pool is the GOKIT1 and for a saltwater pool is the GOKIT1SALT. You have a Max Flo.  

?     Asked on 7/23/2018 by Tom

Hi. I installed my Century Centurion model B130 up to my Jandy JPH2.0CP two years ago and it ran flawlessly until today. Now, it’s hot, and repeatedly cycles in its attempt to start; and has a loud hum when doing so. Do you think it’s the motor or could it possibly be the capacitor?

A  Answered on 7/24/2018 by InyoPools Product Specialist Lennox H.

Hi, Tom. All those symptoms are indicators that the motor is bad. However, you can test the capacitor just to be sure. Steps are available in our How to Test a Pool Pump Capacitor blog.

?     Asked on 5/21/2018 by Clinton

Which seal do I need for the 5bj (B130) motor to attach to a Hayward pump?

A  Answered on 5/21/2018 by InyoPools Product Specialist Hector F.

The seals and gaskets depend on the model name or number of the front pump housing that the motor is bolted to. You can provide us that information so we can check for you or if it is not legible then you can always email us an image of that pump housing to upload@inyopools.com so we can review it and advise. 

?     Asked on 4/28/2018 by Cam

Does this motor come with capacitor?

A  Answered on 4/28/2018 by InyoPools Product Specialist Lennox H.

Hi, Cam. Yes, this motor comes with a 30MFD 370VAC Run Capacitor

I bought this motor for my jandyjhp2.0, I'm wondering if you can tell me which shaft seal and whichhousing seal to get, my serial number is105fk1599 and I don't have a salt gerator or chlorine generator

A  Answered on 5/17/2017 by InyoPools Product Specialist Hector F.

There are three options for your shaft seal being key number 5 on the parts diagram here and the housing gasket is key 10.

Yes, that will bolt up to your JHP.

I just purchased 5224X (B130) - Motor 56j Thrd Full 2hp (b130), could you please let me know the seal kit I need. Thank you!

A  Answered on 5/10/2017 by InyoPools Product Specialist Hector F.

The seal kit will be dependant on the model of the front pump housing that the motor bolts to. Please call in with that model name or number so we can cross reference that for you. If that information is not legible then you can email photos of that housing to upload@inyopools.com.

?     Asked on 4/22/2017 by JY

I have one of these that just blew and I am wondering if I could replace it by a lower HP motor such as the B228SE since it is only feeding my waterfall through a dedicated CJ250 filter (125gpm). I only use it 5 minutes a day to cycle the water a bit so that algae does not settle and on occasion 2-4 hrs straight. Thanks.

A  Answered on 4/23/2017 by InyoPools Product Specialist Scott W.

I will need to know what the distance from your pump to the waterfall is in feet so I can calculate the flow rate to be able to confirm if you can decrease the horsepower on your pump.

I am buying the B-130 pump. Is there any seal kit or another part I need to purchase with the motor?

A  Answered on 9/13/2016 by InyoPools Product Specialist Stacey M.

Does this replace 8-193634-06 with Jandy pump?

A  Answered on 6/8/2016 by InyoPools Product Specialist Scott W.

If it's a Jandy Stealth from before 2008 then yes that would be the correct replacement for that.

Is this a new or rebuilt motor?

A  Answered on 4/5/2016 by InyoPools Product Specialist Alan M.

The Motor 56j Thrd Full 2hp (b130) is new and comes with a 1 year manufacturer warranty.

?     Asked on 2/28/2016 by JY

I have a 7-193634-06 that I want to replace. You list the B130 here as a replacement for mine, however mine has an SF of 10.5 and you list 1.2 for B130. Will it still work?

A  Answered on 2/29/2016 by InyoPools Product Specialist Hector F.

If your part number on your motor is as you provided being the 7-193634-06 then this is the correct replacement motor. It looks the 10.5 number that you are referring to is actually the amps rating on the motor.

?     Asked on 2/6/2016 by Jeff

I have this motor, it just hums. I removed it and shaft spins freely. Could it be the capacitor ? And if so where can I get one.

A  Answered on 2/8/2016 by InyoPools Product Specialist Lennox H.

Hi Jeff, It could be the capacitor, this motor uses the 25MFD 370Volt Run Capacitor (17586325).

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.

Pooi pump motor burned out bearing

Written on 10/27/2018 by Guest

Shut off power to pump motor, loosened connections to filter & suction, removed wiring to motor & external ground, slid pump out, removed impeller housing, removed impeller from motor, removed motor from remaining housing, replaced seals & gaskets, installed impeller housing to motor, installed impeller, attached motor & housings to strainer body with new gasket, replaced wiring & external ground, replaced connections to filter & suction, turned power on & bingo, every thing worked. Note: all gaskets & o-rings were treated with the sealant. Flow to pool is much higher & pump runs with little noise!!!!!

Pump motor wore out

Written on 1/10/2017 by Guest

Inyo Pools had the best price I could find on line for the B130 pump motor. Purchased motor and seal kit and it was at my door in 3 days. Easy replacement, just label wires or take a pic for reference. You're going to lose some water when you pull motor out so don't forget to prime the pump before you turn it on. I'm not a pool repairman, just an average diy guy with a few tools. Took me an hour and a half (lunch break included) to do the job. Was going to cost me 850.00 minimum to have a pool guy do it. Did it myself for 300.00 and change. If I can do this, anyone can. Thanks Inyo Pools!!! P.S. Great diy video!
