Would you be able to give me the part number(s) for replacement capacitor(s)? A run and a stop capacitor? Century Centurion Part 7-193994-06 Part # B842 I think i should try them before replacing the entire pump.

A  Answered on 5/9/2019 by Industry Professional

The motor mfg's do not provide a breakdown list of what motor has what capacitor inside, you will need to look at the capacitor & read the MFD or UF # ( example on run capacitor 40 MFD +- 5% , start capacitor 53 -64 mfd )

I recently submitted a question and have an additional question. My pool pump is the Jandy Stealth SHPF1.5 (pic attached). The motor on it is an A.o. Smith. The replacement for the motor is the B2842 but based on my pool pump it says the replacement motor for that pump is B2854. Not sure if the motor that is on my pump now is correct. The biggest difference I see is the total horse power. Which replacement motor should I buy?

 Reply

A  Answered on 1/4/2019 by InyoPools Product Specialist Hector F.

The single speed original replacement motor for this pump model is the B842

 Reply

A  Answered on 1/4/2019 by InyoPools Product Specialist Hector F.

Yes, this is the correct single speed replacement motor and for cross-referencing the correct seals needed please click here to view the parts diagram for the pump. Most commonly keys 5, 13 and 15 are replaced. You will need the serial number of the pump to confirm which shaft seal that you will need.

Would this pump be a good replacement for a Pentair 011774? Also with this being an energy efficient model how much of a savings over the 011774 could I see? Last question would if be more economical (energy usage) to go with this motor, or a full-rated 2HP model?

Hi. This B2842 is an energy efficient replacement for model 011774. You can save approximately 15-20%. This motor will be the most economical option. You will also need the Whisperflo Tune Up Kit - GOKIT32 or GOKIT32SALT

Good day, the motor you are going to need for the WF-26 would be 1.5 HP Standard Motor - Full Rate (B2858). If you wanted an Energy Efficient model that would be 1 HP Motor EE - Full Rate (B2841, B2841V1). Keep in mind we recommend to change the seals and gaskets in the pump. Which would be our GOKIT32 or GOKIT32Salt for salt water pools.

Our pool pump burned out and we're trying to match the model. It's a Marathon Electric Mod. 5KC38SN6084AX. 1.25 HP, 115/230v, 3450 rpm, We checked, and this model is no longer manufactured. Any idea what model we should get to replace this motor? Energy efficient is always a plus. Thank you.

Hi Adalton, The A.O. Smith 1 HP Up Rate EE Motor (B863SE) will be the energy efficient replacement for the 5KC38SN6084AX motor.

What is it about the B2842 that makes it energy efficient? The amps seem similar (or greater) to one that is listed as standard efficiency. Doesn't the formula apply the same in both instances (amps X volts = watts?) Wouldn't both types of motors use the same amount of kilowatts? Thanks!

Hi John, Compared to it's standard replacement the B858, it uses less amps to operate.

It can be used on the Superflo but we would need the specific pump model to cross reference your exact motor replacement.

Thanks for the response; would the VS model ECM16SQU also be compatible? (I'm not sure about SF x HP) and is there a recommendation for one or the other of these two?
 Reply

A  Answered on 6/8/2015 by InyoPools Product Specialist Patrick P.

Yes the Variable Speed Motor ECM16SQU is also be compatible. If your pocket book can support it we would suggest the variable speed motor as it will save you quite a bit on your operational costs. We recently wrote an article on Is a Dual Speed Pump or Variable Speed Pump Right For Me. This article should help out quite a bit on determining which route you would like to go.

Does this motor comply with the California Title 20 requirements?
 Reply

A  Answered on 6/7/2015 by InyoPools Product Specialist Alex V.

Terry, California’s Title 20 legislation states that pumps > 1HP (total) must be 2-speed or variable speed, and must have a control to default to low-speed (i.e. timer). We do carry the  2 speed version B2983T.

I need to replace a pool/spa motor. I replaced another one two years ago and this one is identical. I need at least a 1.5 HP and the serial number was 22612CH0614638 and the model is B2848. I see one in your catalog online but the model # has changed to B2842. What is the difference?
 Reply

A  Answered on 4/9/2015 by InyoPools Product Specialist Robert M.

Hello Viruchy - The B2848 is a 1HP motor. The B2842/B842 is a 1.5HP motor. B842 and B2842 are the same motor.

I need to replace (not original motor) an AO Smith B2854 1.5hp motor. This motor only lasted 3-4 yrs. Is there a better replacement out there?
 Reply

A  Answered on 4/3/2015 by InyoPools Product Specialist Robert M.

Hello Dennis - We would recommend a 2-speed motor. Running the motor on the low speed will extend the life of the motor. Model B2982T would be the correct replacement. This is a full rated 1HP motor but it has the same total HP of your motor (1.65).

I have a 1.5 hp whisperflo single speed pump. The motor is humming loudly and going out. Would using a 2hp motor increase the life of the motor or help with the water movement or does it spin faster thus causing a higher output? Thanks!
 Reply

A  Answered on 12/22/2014 by InyoPools Product Specialist Alex V.

Aaron, Increasing the HP wouldn't necessarily increase the lifespan of the motor. Also keep in mind that the higher HP means higher amps (higher electric bill). Upgrading the HP would also mean needing to upgrade the impeller.  You also want to check that your filter can handle the higher HP before making a decision.

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?
 Reply

A  Answered on 2/16/2012 by InyoPools Product Specialist Patrick P.

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.

Why should I purchase a Tune Up Kit?
 Reply

A  Answered on 1/12/2012 by InyoPools Product Specialist Patrick P.

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?
 Reply

A  Answered on 1/12/2012 by InyoPools Product Specialist Patrick P.

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?
 Reply

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.

Screeching Pump Motor

Written on 7/13/2017 by Guest

A couple of weeks ago the motor on our Whisperflo (model WFE-6 ) began squeeling loudly. I've heard the sound before on other motors and I knew that this one was done for. After a web search for the exact motor (AO Smith B2842) as shown on the motor info label I purchased one from INYOPools.com. I also bought the "Saltwater Tune Up Kit Pentair/Purex Whisperflo" which includes gaskets and lubricant for my model.

Steps for replacement
1. Ensure the breaker that powers the old motor has been turned off.
2. Close valves to stop incoming pool water from entering the pump.
3. Set the filter valve to the backwash or rinse setting.
4. Remove 6 bolts and 2 nuts (9/16" socket & Wrench) from the pump assembly and gently rock the motor to disconnect it and the collar from the pump assembly.
5. Use a hex wrench to remove the two small bolts from the impeller cover. The cover should come off easily.
6. Use a phillips head screwdriver to remove the "REVERSE THREADED" screw in the center of the impeller. It's REVERSE THREADED so a clockwise direction is used to take it out.
7. Use a flat head screwdriver to remove to screw on the cover that protects the back of the motor. Remove the cover.
8. Unscrew the impeller (normal thread so counter-clockwise) from the shaft of the motor. You can use the 9/16" open ended wrench to stabilize the motor shaft on the rear so that doesn't turn while removing the impeller.
9. Use 9/16" socket to remove the 4 bolts holding the motor housing to the pump collar remove the collar from the motor.
10. Take a picture of the wiring on the back of the motor to assist when putting it all back together.
11. Use a screwdriver to loosen the retaining screws and disconnect the wires and ground from the back of the motor.
12. Remove wires and protective conduit from the old motor.
13. Move conduit to the new motor, run wires through the conduit, and connect wiring as shown in picture from step 10 above. (Don't forget the grounding wire that should go directly to the ground near the pump.
14. Remove and replace metal backed seal (included in gasket kit) from the pump collar.
15. Remove and replace ceramic/rubber seal (included in gasket kit) from the impeller.
16. Lubricate and replace round and collar shaped gaskets on the collar and impeller cover.
17. Reverse steps to reinstall the collar, impeller, cover, etc. Tighten all.
18. Power on.
