What is Service Factor?
Reply
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.

Why do I need to purchase a new shaft seal?
Reply
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.

Why should I purchase a Tune Up Kit?
Reply
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.

What are the dimensions on the shaft bearings or a part number and do you sell replacements?
Reply
The correct replacement bearing is part number 5270-31. The motor would require two. Here is a link to the bearing.http://www.inyopools.com/Products/07501352012909.htm

1. Watched DIY videos to learn how to install it properly.
2. Turn off the breaker. I took out the pump and the motor together.
3. Took off the motor. Bagged the bolts since there where to different sizes.
4. Took off the power cord, and motor accessories.
5. I built a new power cord. The original was old and weather beaten. I took it to the home store and bought the same parts. Get the proper gauge cord and a new plug. I disassembled the old plug to learn how to assemble the new one. It was easy.
6. Installed the new seal based on the old motor. Simple, but work slowly.
6. Reinstalled the motor blade. Don't over tighten it. Make sure it spins properly or it could bind. Install the safety screw.
7. Installed the pump plate and new seals. I sprayed them with silicone before install.
8. Mate the pump and motor. This is why I took them both off. It's easier this way to ensure the new seal doesn't slip off causing a leak. I put the pump on end and slid the motor in place.
9. Tighten the bolts evenly. Do not over tighten or you could crack the pump plate.
10. Wire the new power cord. I took a picture of the old cord on the old pump and installed the wires the same way.
11. Make sure the plumbing to your pump is on correctly. Do not over tighten.
12.Turn on the breaker.
13. Turn on the pump.
This took me 3 hours or so. I took my time and went step by step. I used the old motor as a guide. I took pictures to use as a reference. Doing it myself saved me 500 dollars. The local pool place wanted 1300 or so to do the job. Plus they wanted 300 more for the motor. It's worth trying to DIY.

Once I received my new motor from INYOPools I replaced the old motor. With the help of videos it only took approximately 1 hour to change the motor and get my pool back up and running. Ordering was easy and shipping was quick which helped keep my pool water from turning green.

We removed the pump assembly from the PVC pipes. We were fortunate that the bolt holding the pump impeller and the pump motor was not frozen. We removed the 4 bolts holding the pump housing to the motor and then were able to use a wrench to hold the long shaft bolt while we turned the impeller counterclockwise. Once we were able to break this bond, the assembly was simple. Attached the new motor to the impeller and then attached the housing to the motor with the 4 bolts. We then reattached entire assembly to the PVC pipes and turned on the pump. Ran perfectly. Total time was less than one hour.

Ordered the new pump to match the old one per the label. It arrived as shown and promised. I replaced the old pump motor with the new, it was a perfect match and when I turned it on it was nice and quiet with no issues!

After watching the Inyo videos for replacing a pool pump motor and replacing the shaft seals several times (which are both excellent step-by-step videos), I also searched YouTube and found a video on replacing a Jandy pool pump motor specifically. I'm glad I did because my Jandy PHPM pump had a few more steps to do than the Inyo video that used a Hayward pump. But together, these videos made changing the motor and shaft seals relatively easy. I was worried that after replacing the motor and the shaft seals myself, I would be turning on the new motor and watching a new water leak. But I was pleasantly surprised and relieved of my worries when that didn't happen. The new motor runs smoothly, incredibly quiet compared to my old failing motor, and without any leaks. As an additional note, the shaft seals are easy to replace (no special techniques) and the electrical wiring (230V from a double breaker for this motor) to the new motor was totally simple - two black wires to the two uncolored leads and one green ground wire to the green colored lead - that's it! No chance of screwing it up!

I tried replacing the Start Capacitor but that did not resolve the problem
I then shut off the breaker and disconnected the power lead.
I disconnected the plumbing connections and removed the pump
I have a Jandy filter, so the first step was to removed the basket housing. 8 bolts
I then remove the impeller housing . two small screws. Note the arrow on the covers for reassembly
I them removed the impeller screw. Note: it is reverse thread, and you will need to hold the motor shaft to remove the screw.
I then removed the housing plate to the motor. 4 bolts. The seal is held in by this housing so note how it is installed prior to removing the seal.
Installation was the reverse of the step I described. Always use a new seal.

Noticed old pump was very noisy. Checked and could hear bearings failing inside motor. Checked local pool supply store , they where trying to sell me complete new pump assembly. Being the craftsman that I am I got on Inyo website found the correct pump motor. Had it to my home in a couple days. Removed old pump motor. Installed new pump with new seals and gaskets. Fit was perfect. Wired motor up. Flipped the switch and works great. Pool circulation is better than ever and super quiet.

I have two identical pumps, one for the swimming pol filter and the other for a waterfall feature. The waterfall pump stopped working an would buzz when I turned it on. I initially replaced the capacitor which helped a little as now the motor would spin for a while and then stop.
I suspected a bad bearing. I tried finding a replacement via Hayward but had no luck searching for the pump model number I found INYO and ordered the pump. When t arrived I replaced the bad pump with the new model wired it up and all is now working. Great price and confidence in a perfect match.

Made sure 3 times the breaker was off
Took off the housing bolts and pulled existing motor away from the pump.
Cleaned the impellor and wiped down all the parts going back with the new motor and also made sure to clean the electrical cord going to the new motor to be able to make a clean connection.
I then added the new gaskets and put the motor with the pump connected the wires and tested it. Tt worked great! It took some time but with some wd40 and towels to wipe things down it makes it a fast clean job.

Pretty simple. I took the old one off, put the new one on. Took the wire connections off along with the four motor mount bolts and that was it! It is a really quiet motor! Worked great, easy ordering! Best price around!

purchased new motor (I had new gasket and seal on hand) and replaced. it took a total of 2 hours with basic tools. this new pump motor is so quite I have to keep checking on it to see if it is running... It has been on-line now for over a month with no problems. I would be somewhat lost if it weren't for watching the "how to" video. thanks.

Pros: Customer service, shipping time, price and product
Cons: None that I can think of
Best of all is the wonderful customer service help provided by Inyopools. The product was here in the time specified and the price was considerably less than the 5 other companies I checked with first. The product was as specified and ordered and hasn't given me any problems to date. It was installed about a month ago.

(5 out of 5 stars) Direct replacement for our Pentair WF-26
Reviewed By: Inyo Customer ()
First and foremost, thanks Rich N. for recommending this motor as a direct replacement for our 8 year old Pentair WF-26 (just based on the motor label) whose bearings were shot and making a really loud whiney noise! I received the motor in 3 business days. I watched the YouTube installation video by Inyo Pools and got it up and running within 45 minutes. The kicker? I saved over $900 by ordering the motor from Inyo Pools and installing it myself (local pool maintenance company quoted $1,204.69 to do the job). It was daunting at first, but ended up really easy. The hardest part was seating the pump seal gasket (GOKIT32) and keeping it in place while remounting the seal plate onto the pump. That and maneuvering the old and new motor in and out of all the pool plumbing. Thanks y'all, wasn't expecting our pump to blow out on us right at the worst possible time. Really wanted to replace with a variable speed pump, but didn't have a budget for it and needed a replacement FAST due to the subfreezing temperature we were experiencing all week in North Texas. We'll count on Inyo Pools to upgrade to a Pentair Whisperflo VST 2.60 next pool season!

(5 out of 5 stars) Pump Motor Replacement
Reviewed By: Inyo Customer ()
the motor is fairly easy to install. A one-man job. After viewing the DIY videos, the installation took about 3 hours. It would have been just two, but I had to make it more difficult than it had to be. Had an issue with the reassembly that occurred due to my failure to adequately document the disassembly of the diffuser and impeller assembly. Totally on me. That being said, the motor has performed well.

Researched how to change a burned out motor on the INYO Pool website. Very easy to look up the exact motor I needed along with the shaft seals. Ordered the motor and seals on Dec 20 and everything arrived on the 24th. Took 1 hour to replace the motor and saved myself $300.00 by not calling a pool service.
