I want to buy a Century B855 motor to replace my current B855 motor. What tune-up kit should I buy? And do you have any articles or video's showing how to remove and replace the impeller?

Hi David,The tune-up kit depends on what kind of pump you are putting the motor on.  Here is a link to the different gokits (tune up kits) we sell.  You can click on the proper manufacturer and model of your pump to help guide you to the correct gokit.We do have a lot of pump and motor how to guides.  Here is a link to Replacing your Pool Pump impeller

I am looking at your b855 pump motor (part num 0-177897-22) . my issue is I think I have read where you should also replace the seal , however the label on the pump is not readable. I need to order the seal kit and the correct motor.

 Reply

A  Answered on 4/23/2021 by InyoPools Product Specialist Craig C.

Hello David.  Thank you for the pictures.  From the pump lid, C3-139P1, I was able to determine that you have a Stay-rite Dura-Glas or Sta-rite Max-E-Glas.  If you currently have a 2 horsepower motor, the Century B855 is the appropriate replacement.  A new shaft seal should be installed when the motor is replaced.  I would suggest a tune-up kit, GOKIT6, which also contains rubber gaskets and o rings that should also be replaced.  The GOKIT54 can also be used by simply removing the copper cone insert from the seal plate.  At times, working with the copper cone insert can be problematic.  I would recommend the GOKIT54.  Tune Up Kit Sta-Rite Dura-Glas & Max-E-Glas Pump 1998 To Present - GOKIT54  Century 2.0 HP Square Flange 56Y Up Rate Motor - B855

Hi Kenneth, You will require this SPX3210Z1BE Hayward Replacement Motor from the photos we cant confirm 100% on the seal you need. Could you send a few more photos of the pump, we think it is a Hayward TriStar, is there anything on the pump housing which says Tri Star? Is that EF1000 number coming off of the filter or the pump? Simply click the reply link below to supply additional information and photos.

    The motor is a Century motor. I have attached a couple of more pictures. the EF1000 is on the filter housing. I would like to have a 2 HP pump. That is what was originally put on the pool for the accessories, waterfall, slide, etc...

     Reply

      Hi Kenneth, The Energy Flo RS pump was sold exclusively through Leslies. It looks to be the same pump as this Hayward TriStar Pump but we are unable to get 100% confirmation. If you want to take a quick look at the TriStar Parts Diagram and let us know if this looks like your pump. If so then we can supply you needed parts to upgrade to 2 HP. Another option is to remove the impeller from your pump and let us know if there any part #'s stamped into the impeller.

 Reply

A  Answered on 4/27/2020 by InyoPools Product Specialist Patrick P.

Yes you can but you may have a little bit of re-plumbing as the plumbing ports are not in the exact same location. You will also lose a little bit of flow by going down from 2 HP to 1.5 HP so if your pump is powering spa jets, water features or solar you may not want to consider the downgrade in HP.

Can I replace a century PN B842 with a century B855 pump? I know that the B855 is a 2 horse, is that the only difference? How about noise, the 842 has always been very noisy
 Reply

A  Answered on 3/31/2020 by InyoPools Product Specialist Matt S.

Yes, the B855 can replace the B842, as they have the same total horsepower. Besides the horsepower and service ratings on the labels, they are pretty much the same motor. The noise will be no difference between a brand new B842 or B855

    So I received the new motor from you and I’m in the process of taking apart the old motor. I’ve hit a snag and I’m not sure what to do. I think I’ve removed the impeller but there’s shaft seal does not want to come off. Is it supposed to be attached to the impeller? Also, how does the mounting bracket come off? Your installation videos suggest there are (4) bolts holding it in place but don’t see them.

Hi. Does the B855 Centurion motor have a start capacitor in addition to the run capacitor? And if so do you stock start capacitors? As I understand it the run capacitor is mounted on the top, (under the steel hood or cowling). (My problem is the motor is reluctant to start but if i turn the motor drive shaft at the rear of the motor it spins up and runs fine) Thanks.

A  Answered on 3/2/2020 by InyoPools Product Specialist Lennox H.

Hi, Jim. The B855 motor is equipped only with a Run Capacitor - RD-50-370. It sounds like the capacitor is bad and will need to be replaced.

Unfortunately the B855 is not a compatible replacement for your B129. Please click here to be directed to your single speed model motor replacement. Also, most commonly the reason for a motor to hum and not move any water is due to either the start capacitor failing or the motor has failed. You can disassemble the motor from the pump housing to inspect the parts and bench test it to be sure, and also test the capacitor

So these seals can easily be compromised if touched, wet or dirtied on the ceramic sides of the seal. You may be able to clean it off with rubbing alcohol and a clean cloth. Also, that seal requires some silicone to be used on the seal plate where that portion of the seal is placed into the seal plate.

Most likely the two yellows are hot however I would recommend using a multimeter on those leads to test and be sure. If so, then you are correct that at 220/240 voltage each lead would not matter if either is on terminal 1 or 2.

Both of these motors have matching total horsepower ratings of 2.2- HP (Listed HP x Service Factor (SF) = Total HP).

Part # B855 is the motor only. Not exactly sure what you need for a pump but you'll see a few options under "Parts" at the bottom of the page.

My pool pump motor is running really hot. Do you think a bearing replacement is the fix or a new motor
 Reply

A  Answered on 9/23/2015 by InyoPools Product Specialist Lennox H.

Hi, If the motor is suddenly overheating you can follow some of the recommended troubleshooting steps we have in our Why Is My Motor Running Hot? blog. If non of these solve your problem then the motor will have to ve replaced.

My old motor has locked up after about 6 years. It appears you have a replacement for $245+ but my frame says Y56Y and your listing only says "56Y". Is this the same thing? Otherwise everything seems the same.
 Reply

A  Answered on 9/9/2015 by InyoPools Product Specialist Alex V.

Hello, The Y56Y and the 56Y are the same frame. As long as the specs match, this motor will work. Be sure to replace the pump seals as well.

Is this motor already preset for 230 volts or is there a switch that has to be placed for 230 volts? Also I have a red, black and green ground coming to the motor. Would the Red and the black wires go to L1 and L2? The reason I ask is because internally there is a white wire on L2. The terminals in the motor are "B", "L1", "L2", and "A". Your help is greatly appreciated.

A  Answered on 8/31/2015 by InyoPools Product Specialist Lennox H.

Hi Ed, The motor comes set for 230 volts. When wiring the motor for 230 volts both lines are115 volts so it will not matter if the "red" or "black" wire goes to "L1" or "L2". The "green" would go to the ground.

What motor bearing part number do I need to order for this B855 motor? When I replace the bearings, what else should I replace?
 Reply

A  Answered on 8/31/2015 by InyoPools Product Specialist Lennox H.

Hi Jesse, You would need (1) 304 Bearing (6304) for the Shaft End and (1) 203 Bearing (62032RS) for the Opposite Shaft End. It is also recommended that you replace the shaft seal and the o-rings within the pump housing.

My pool motor is making a grinding sound ... water is being pumped. It is a Century Centurion Part # 7 - 159988 -06 , 2 HP , SS# 028083M Type CX , 230 volts, Amp. sf 10.5 About 15yrs old. Is my motor bad? What do you have and how much?
 Reply

A  Answered on 8/24/2015 by InyoPools Product Specialist Lennox H.

Hi Ed, It sounds like the bearings is going bad on the motor. Since the motor is 15 years old I would recommend replacing the entire motor. The A.O. Smith 2 HP Full-Rated 56J Motor (B130) would be the correct replacement motor based on the part # 7-159988-06.

What is the flow rate of the B855?
 Reply

A  Answered on 9/10/2014 by InyoPools Product Specialist Patrick P.

The flow rate is determined by the pump model (listed on the pump housing). The B855 flow rate will vary depending on the pump model.

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.

Challenger Pump Motor Squealing

Written on 3/22/2021 by Guest

After Texas freeze my Challenger 2hp pool pump started squealing pretty bad. I ordered a new 2hp motor from INYO Pools and had it shipped to my home. Step 1. After turning off the power to the pump pad and putting the multi-port in the closed position, I drained the pump and removed the motor and impeller assembly from the wet side of the pump, unhooked electrical connection to motor* and took assemble to work bench. 2. I took off the diffuser, impeller, and back plate off the old motor. 3. I installed back plate, new seals, impeller, and new impeller retaining screw onto new motor. 4. reinstalled diffuser and new diffuser o-ring and took assemble back to pool pad 5. connected electrical wires to new motor*, installed new housing o-ring, re-installed motor and impeller assemble back onto wet side of pump. 6. filled the strainer basket up with water. 7. put multi-port valve back into filter position, 8. Turned power back on to pool pad and turned on pump. 9. Checked for leaks.

*Make sure you are familiar with basic electrical connections before attempting this repair. If you are not, have a pool professional install the motor. It’s not worth saving a few bucks if your house burns down or worse yet, you severely injure yourself or get killed in the attempt to fix your pool pump.

My water level went below the skimmer line and my pool motor burned up.

Written on 8/20/2017 by Guest

Being a female and not all that hip on motor repair, I looked at many youtube repair videos. I knew what kind of motor I needed because I was replacing one and I wanted the same as I had. I ordered the motor and gasket pack and it arrived very quickly. So I turned off the electricity FIRST! then I disconnected the electrical connections to the motor. Took all the bolts out and took the motor off the pump parts. My main problem is the impeller had fused to the motor shaft which presented a big problem. Couldn't get it to unscrew. I did however finallyhave to demolish the impeller and had to dremmel the metal cap that was on the impeller to get it off. This was a very hard project. Took me several hours. But then I just looked at the videos again and put all the pieces back together per the videos. The youtube videos are amazing. Even someone inexperienced can do this repair with the step by step instructions. Also, very helpful is to take pictures of each step and what things look like and how wires are connected. You can refer back and say, oh, this goes like this and this was like this. Very smug with myself for having done this alone. So don't pay those pool people to do this for you. It may take a lot longer than the videos, but if you take your time and are careful and deliberate, you can get it done. Just remember the electricity!!!

Old motor burned up.

Written on 5/24/2017 by David G.

Pretty straight forward if you have basic skills and tools. The most difficult part for me was removing the impeller from the shaft on the old motor. It was so tight that I cracked the impeller with a pipe wrench (my bad). Had to order a new impeller and go buy a strap wrench that fit over the outer edge of the impeller to break it loose. The good thing about the Challenger motor is that you don't have to remove the back end and move internal parts to access the end of the shaft. (The INYO video uses a Hayward motor which is more involved.) It has a small plastic cover over the shaft end that sticks out the back of the motor. Easy to grip when turning the impeller. Otherwise the video shows just how simple it can be.
