Hi. I believe this is the correct replacement motor. But Iā€™m not sure which seals or go kit to get. Is this the newer or older version PB4-60?

A  Answered on 5/28/2019 by InyoPools Product Specialist Lennox H.

Hi, Sean. This B625 is the correct motor. You will also need the Tune Up Kit - GOKIT71.

I would like to replace the vacuum motor, I need help locating the right one..... CAT B625 Serial CA01-25 Part 8 - 173840-23 Type CS FR N56CZ HP 3/4 SF 1.50 HZ 60 RPM 3450 Volts 230/115 Please let me know and would the screws line up as well, Thank you and have a great day

A  Answered on 5/25/2019 by InyoPools Product Specialist Patrick P.

Hi Thomas, The B625 replacement motor is the correct replacement motor for your pool vac motor shown in your photo. You will also need a Seal Kit when you replace your motor and the two most common pumps that use the B625 are the Polaris Booster Pump and the Letro Booster Pump. If you have the Polaris Booster Pump then you will require this Polaris Seal Kit and if you have a Letro then you will require this Letro Seal Kit. We have also put together this Video on How to Replace a Booster Pump Motor which you may find helpful when you tackle this project.

I ordered a Polaris Booster Pump Motor-B625, it looks like I need an o-ring for the shaft. Does that come with the motor or do I need to order one & what is the o-ring P/N?
 Reply

A  Answered on 5/5/2019 by InyoPools Product Specialist Joe S.

When replacing the motor on the booster pump we would recommend the Polaris Booster Pump Shaft Seal 5/8" - P55 and O-ring, Bracket To Volute (258). These do not come with the motor.

Good Evening, I just want to make sure that A.O. Smith P/N 3262-18 is a direct replacement for A.O. Smith P/N 7-193794-50. Thank you, Rex O.

 Reply

A  Answered on 4/23/2019 by InyoPools Product Specialist Lennox H.

Hi, Rex. This B625 is not a direct replacement for P/N 7-193794-50. The P64 replacement motor is no longer available.

Just started the pump and there water leaking around the drain plug, does this plug require an o ring? I want to try this first before ordering a seal kit. Thanks!

 Reply

A  Answered on 4/25/2019 by InyoPools Product Specialist Lennox H.

Hi, Alan. The Polaris Booster Pump drain plug does not require an o-ring. You will have to try the Polaris Booster Pump Tune Up Kit - GOKIT71

I purchased this motor (B625) recently to replace my current one which is screaming like a banshee. What else do I need to install this motor (seals, o-rings, impeller?). P/N is 0-173840-23, S/N is 35717CH. Thanks!
 Reply

A  Answered on 1/30/2019 by InyoPools Product Specialist Steve M.

Hey Brad, with any motor replacement we suggest replacing the seals and gaskets in your pump. This will help to prevent water intrusion and extend the life of your new motor. The seals are specific to the wet-end of the pump and we will need that model information to identify what they are. The impeller rarely needs to be replaced unless your unit is over 10 years old, or there is visible damage to the impeller.

I have a Century Pool and Spa Motor (Booster Pump), CAT# B625, Serial# BW3-16, Part 7-173840-23, HP# 3/4, SF# 1.50, PH# 1 with RPM# 3450. This pool pump is having a loud noise, it is working fine and pool is cleaning well. The noise just annoy, is this a sign of bearing going bad. (1) If I need to replace a motor, what motor can I buy (2) Do I need to have GO-KIT (all the O-Rings, Shaft seals etc) (3) And do i need a new impeller, which model should I buy.

 Reply

A  Answered on 12/3/2018 by InyoPools Product Specialist Lennox H.

Hi, Afab. Yes, the sound that is coming from the motor is a sign that the bearings are failing. This Century B625 is the correct replacement motor. I would also recommend getting the PB4 Tune Up Kit - GOKIT71 and the Impeller - P15

Do I also need to replace booster pump on motor
 Reply

A  Answered on 1/8/2018 by InyoPools Product Specialist Lennox H.

Hi. You can replace just the motor and seals if the pump wetend is in good condition or the entire pump PB4-60 if the wetend is bad or damaged.

?     Asked on 7/22/2017 by George

This is the part number on our Polaris pump. The motor is screaming. Sounds like a bearing's going. Is there more I should know or is this a direct, bolt-on replacement? Thank you.
 Reply

A  Answered on 7/23/2017 by InyoPools Product Specialist Lennox H.

Hi, George. This motor is a direct bolt-on replacement for the Polaris Booster Pump. I would also recommend getting the Shaft Seal P55 - (OEM) or PSR-1000 (Generic).

On the a.o. Smith b625 what is the correct wiring as it has an L2 and an L6. Using 220
 Reply

A  Answered on 4/7/2017 by InyoPools Product Specialist Andy O.

Hello Scott- The wiring diagram is on the label of the motor. Since you are using 230v you would use the high voltage wiring diagram. According to that label, it shows you would connect 1 of your hots to line 1 and the other to line 2 and as always ground on green.

Does the motor include the capacitor? Or is that a separate purchase?

The Motor Polaris Threaded Shaft .75hp (b625) includes the capacitor.

My motor is making screeching noises, an indication of a leak towards your shaft seal. Once the water reaches the motor, the screeching starts. Can I stop the screeching or do I have to replace the motor?
 Reply

A  Answered on 3/29/2016 by InyoPools Product Specialist Scott W.

Good afternoon Terry,Yes once the motor gets wet it needs to be replaced. The part number for the shaft seal that you'll need to order with the new pump is going to be 3262-04.

What is the difference between the B625 and the (B625) 3262-18?
 Reply

A  Answered on 3/21/2016 by InyoPools Product Specialist Lennox H.

Hi Brent, The p/n are the same. However if you were meaning to find out the difference between the B121 and B625, the B121 has a "keyed" shaft which requires the Shaft Extension (150) and the B625 does not. The B625 has a threaded shaft.

I keep blowing start capacitors. What is the correct size for a b625 Polaris pump?
 Reply

A  Answered on 3/10/2016 by InyoPools Product Specialist Lennox H.

Hi Richard, This motor uses the 124-149 Mfd 125v Capacitor (BC-124). If it keeps blowing the capacitors then the motor will need to be replaced.

My booster 7-173840-23 is making a high squealing. Noise like the bearing is going out. Is there bearing inside or what is making that high pitch noise
 Reply

A  Answered on 12/1/2015 by InyoPools Product Specialist Charlie R.

Mr. Singh,Yes, there are bearings inside your motor. Typically, once the motor starts making screeching noises, it's an indication of a leak towards your shaft seal. Once the water reaches the motor, the screeching starts.

Will this motor be more energy efficient than my original Polaris Booster pump motor? And if so, is it possible to quantify by how much? I already got a variable speed pool pump installed. So now I was looking to get more energy efficient with other pool related equipment.
 Reply

A  Answered on 11/16/2015 by InyoPools Product Specialist Charlie R.

Brian,No, this motor is not considered energy efficient. Unfortunately, there is only one motor that will fit the Polaris Booster pump.
