Do you ave a schematic on the location of the capacitor?

A     Answered on 10/17/2018 by InyoPools Product Specialist Lennox H.

Hi, Gary. We do not have a wiring schematic for this motor that shows the capacitor. However, the Start Capacitor is located to the rear of the motor under the cover.

Can the 3x5 base/stand be removed?. My current pump has a plastic base that extends under the motor.

A     Answered on 9/20/2018 by InyoPools Product Specialist Lennox H.

Hi, Ron. The base is unable to be removed from the motor. 

?     Asked on 3/13/2018 by Michael

I have a hot tub that I had to have the pump repaired. The pump is a Magnatek 7-182895-02 that I had rebuilt because the bearings were froze up. Upon hooking it back up it is kicking the gfi off when I turn the pump on. Is it possible that they put the 2 wires down on incorrect pins? It is being run as a 120 volt system with only 3 wires from the control panel. They are white, black and green. Any suggestions that you may have would be greatly appreciated! Thanks in advance! Michael

A     Answered on 3/14/2018 by InyoPools Product Specialist Lennox H.

Hi, Michael. It is possible that the motor could be wired incorrectly, or the motor is bad. You can use our Pool Motor Troubleshooting Blog to find and correct the issue.

I just ordered this motor to replace the one that I have. What pump & pump seals should I get to go with this? thank you! Val

A     Answered on 11/14/2017 by InyoPools Product Specialist Hector F.

In order to cross-reference the correct seals that you may need, you will need to provide us with the model name or number of the front pump housing that the motor attaches to. If you cannot locate that information then you can email us an image of the housing to upload@inyopools.com so we can assist in identifying that model.

Do you provide an impeller replacement for a magnatek Century Pool/Spa motor (7-182895-02)?

I have a hayward power flow LX its a hp 3.0 spl. model # sp1580z2. will this work as a replacement

A     Answered on 3/28/2017 by InyoPools Product Specialist Scott W.

That is fine, but you will want to the correct impeller for the horsepower, part number 5111-07J, and the shaft seal, SP1500KA. You also want to make sure that your system is able to handle a decreased flow rate.

Can the bearing be bad in the motor I have a high pitch squel

A     Answered on 10/12/2016 by InyoPools Product Specialist Hector F.

This is one of the signs that the bearings are going bad in a motor. To confirm the bearing part numbers for that model motor you would need to touch base with A.O. Smith at (800) 262-6484.

Hi.... I will be buying a BN40ss motor to replace a magnetek motor (7-184518-02 ) How do I know which shaft seal to get? It will be used as a spa motor/pump. Thanks

A     Answered on 3/1/2016 by InyoPools Product Specialist Lennox H.

Hi Bill, We would need the manufacture and model of the pump wet end in order to find out which shaft seal is needed for that pump.

Information of my jacuzzi pump, Flo master 031221762-1 code 08016 serial #203172-024 FMHP 553022 which pump is the replacement. Also, water exits from side of impeller not top. Thanks, Leo

A     Answered on 3/1/2016 by InyoPools Product Specialist Lennox H.

Hi Leo, None of the info provide allowed me to cross reference it to a specific Flo-Master Pump. The FMHP pump does have a side discharge but I'm not sure if this motor is the correct one. If you can send us a photo of the motor label I will be able to confirm if this is the correct motor.

will a flo master XP2 pump by aqua-flo fit this motor?

A     Answered on 7/24/2015 by InyoPools Product Specialist Charlie R.

Danny,As far as bolting up to the XP2 pump, yes both frame sizes of motor and pump are a 48Y frame. Because I do not know the horsepower or specs of the actual pump itself, I wouldn't be able to confirm if this motor will run properly with the pump, though.

?     Asked on 7/21/2015 by Gary

will a pn315-1160 wet head fit this motor?

A     Answered on 7/21/2015 by InyoPools Product Specialist Matt S.

Hello Gary, The 315-1160 is the front volute for a Waterway Hi-Flo pump but it does not identify the HP of your particular wet end. But I can say from the numbers provided, the BN40 will work for the Hi-Flo series.

Why should I purchase a Tune Up Kit?

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.

?     Asked on 1/12/2012 by Guest

Why do I need to purchase a new shaft seal?

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?

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.
