Can the bearing be bad in the motor I have a high pitch squel
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.
Impeller bad need to replace 1 HP not 2HP
Hi Phil, Could you let us know the make and model of your pump as this would help us determine which impeller you need.
Is a 2 HP pump about right for 24' round above ground pool that is 56 inches deep?
Hi Alan, You should actually be fine with a 1 HP Pure Pro XL Pump on a 24' round pool or possibly a 1.5 HP.
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
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
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.
Hi, Is the BN40ss a direct replacement for a Magnetek 7-184518-02 ? Thanks
Hi Bill, The BN40SS will be the direct replacement for p/n 7-184518-02.
will a flo master XP2 pump by aqua-flo fit this motor?
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.
will a pn315-1160 wet head fit this motor?
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.
Is the BN40SS a direct replacement for the magnetek 7-181579-02?
Hi Dave, yes the BN40SS a direct replacement for the magnetek 7-181579-02.
Hello, we currently have a broken magnetek b124. this model's numbers and frame style match. Can we use this one?
Hello Sue - The BN40SS would not be a compatible replacement. We would recommend going with the B124 motor.
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.
