I know it's 8 years later, but what a great, informative video! Thanks for saving me some money!

[@jmercapidez5346]

I have a Balboa heater , I followed your instructions to fix the board and my heater works great. Thanks so much Sr

[@seasidescott]

Like others, wishing you'd teach everything else I need to know because your style is a joy to watch and the speed at which you speak is perfect for keeping my attention.

[@SpaGuy]

Thank You Scott!!

[@DavidBaanstra]

I've watched a lot of videos on repair--mostly motor vehicle. There are some good ones, some bad ones and some that will get you by. This is the BEST, most explanatory, well filmed, and easy to follow repair video I have ever watched. Great job

[@SpaGuy]

Thank You David..

[@Ricky_Mason]

I was going to look for some silicone for a seal replacement but realized you sent a small tube with the parts. Great videos! Thank you

[@Cjholloway]

Just rebuilt 2 pumps for my hot tub. Got the parts from the Spa Guy and followed the video! Woo Hoo I’m back in the Hot Tub! Thanks Spa Guy. You’re the real deal and a great guy!

[@jjl2267jb]

Just ordered the parts from the Spa Guy to rebuild my pump. This video is going to make this rebuild go perfect! Thank you for such a comprehensive information.

[@lawrencegraham0]

I have a Four Winds Utopia III that I just bought used. None of the three motors would turn over upon hook-up as I found out. Two of the motors I discovered had bad capacitors, but the third was completely locked up. All motors are Gecko AquaFlo XP2E 5hp. I thought I was going to have to buy a new one, but after seeing this tutorial I might have a chance to rebuild it and save $$. Thank you so much!!

[@tompestak6530]

Thanks in large part to this video I was able to repair my Executive 56. I did not have any back plate squeezing the bearing. When I got in there, there was only 1 screw and it seemed to be secured to a small, oddly-shaped but tapped piece of metal. It had a protruding, curved end that may have been pressed against the bearing. At any rate, I set about creating my own plate out of steel and that was by far the most time consuming thing. My motor sounds a bit louder now. Not sure if I should be concerned or not. But it's working and no more leak. Thanks! I was able to pull the bearings off with the 3-Jaw Puller set from Harbor Freight, although I had to change the configuration of one of them to pull the middle bearing. Thanks for the detailed notes on your website too so that I was able to ensure I was buying the right replacement set.

[@SpaGuy]

Thank You Tom!!

[@ruellerz]

Kick ass tutorial! I was about to throw in the towel on the hot tub but this might be the last repair :D Parts order! Two Wet ends going in!

[@mishaux]

You sir are an artist. It's a real pleasure to watch such a conscientious mechanic at work.

[@SpaGuy]

Thank You for watching..

[@BrendanKBuckley]

As well as marking the parts for re-alignment, I always use my cell phone to take photos of the electrical connections. As a retired Electrician, I've used this method my times to photograph complex wiring terminations. Trust me, it really helps.

[@z-licious]

Yes it does! Great advice

[@seasidescott]

lmao, me too. thank goodness for phone cameras as there was always something I forgot to put in the drawings we'd have to make back in the old days. I actually bought my last phone (Pixel 7 pro) because the camera does such a good job on parts, up close, low light.

[@ianspeare5520]

Wow my friend I have never commented on a video love reading them for laughs. However I have to say wish my professors in university taught and explained the way you do. Thank you from your Northern nieghbor in Canada 🇨🇦 stay safe and keep posting.

Great to see a real Mechanic at work we fix what can be fixed ! Good job !

[@dlmsenti6562]

After watching this video I was able to disassemble and order what I needed to reinstall the bearing and seals , thanks Spa Guy .

[@solonutiket564]

Thanks for the info. Very informative video. I am new to hot tub maintenance. I think I am old school. I install my bearings using a "slip fit". That is done by placing the stator in the freezer for an hour, and then placing the bearing on top of an old incandescent light bulb until it is hot. Then get the stator out of the freezer and slip the bearing on. No force needed.

[@SpaGuy]

That is old school..

[@wayne6066]

Your tricks of the trade are invaluable. Thank you Spa Guy!

[@FrugalFixerSpike]

I fix about anything, with your info, I fixed this pump real easy. Thanks for the tips and thoughtful way you work and think!

[@zarcyne]

See, now that's cool! Most guys would be trying to just sell you a whole new pump motor and this guy is making a video showing you how to repair it with parts for lot less.

[@OrtonGamer1]

Great video! Almost anybody can fix their own wet ends with this video. Well done sir!!

[@T.C..]

Thank you, your advice at 28:42 on the switch brought all my frustration to an end... Thanks again for the excellent video

[@davehunt6993]

Thanks for the help. You made rebuilding two wet ends eazy peazy.

[@markgerardy]

Really want to thank you for your video. Because of your very-well done video, I was able to fix a corroded pump seal on my Executive 56 hot tub pump with a 100% success rate the first time. Ended up scoring an entire wet-end subassembly for $80 instead of replacing the pump seal and the corroded impeller ceramic hub - but it was well-worth the extra $30. And yes, I turned off the electricity at the breaker box beforehand. I certainly knew to do this anyway (know my way around the workshop) but just for the record, I happily-complied. No shocks here :)

[@moink101]

You said the internal switch needs to be flat / straight whichever. Do you happen to have a better picture of the orientation? Not sure where it should sit. Not getting the low setting. Also, I had some water get into the motor and cause an arc in the winding. I took it all apart and got it dried but I'm still getting a lot of that residual electrical burning smell. Will that ever go away or is the winding just waiting to die?

[@kennycheng5455]

awesome video.. I ended up replacing the whole pump + the wet end :) thx you

[@Tubedog8]

I did it! Although my motor (really old) was not the exact model Spa Guy directed be to the right parts after I send photos of what impeller I had. I changed the front bearing. ( I borrowed a puller from Autozone) and I replaced the impeller and the seals. Runs great!! Thanks Spa Guy! Could not have done it without your help!

[@stevej3872]

Thanks for this video. It was very good and helpful. I completed all the steps, but for some reason, the pump won't pump water through to the jets, even though can hear it running. It worked before the wet end (leaking) was replaced, but not now. Prior to turning it on (closing up wet end), quickly tested propeller, and it was moving, so I can't figure this one out.

[@paulsheremeto4475]

Fantastic video. Step by step instructions. Followed them to a tee and voila. EVERYTHING is covered in this video. Great job.

[@Jacey2001]

I have an Executive 56 pump thats only 4 years old. the seals went so I bought the impeller kit with seals. The wear ring in mine had no flange. it was just a cylinder shaped ring. and its too small for to seal the gap... and to top it all off... I lost the original impeller that I took out. Can I buy wear rings separately?

[@Killiecrankie1314]

Fantastic video! Excellent instruction - and a craftsman. Thank you.

[@Dean-Sala]

This video is exactly what I needed to see. I was unsure about the new seals because they seamed lose against the impeller shaft and not make contact. You explained that there can be impeller shaft swelling against the old seals. This is exactly what happened to the old impeller on my pump. I see now the joining of the seals together(round spring seal against ceramic seal) is what seals in the water, not the internal shaft contact. Lesson learned. Thanks

[@teslam3m592]

My motor shaft spins freely and doesn't lock up at all. But it doesn't spin as freely as yours does. Do you think the bearings need to be replaced?

[@douglasmarshall7266]

Great video. One of my 8 screws broke that attaches the volute to the face. Would it be fine with just 7 screws holding it together? I cant get the broken part of the screw out. I think you called it a neural, which keeps spinning. Do you know of any way to get them out? Thanks

[@SpaGuy]

On some volutes you can drill through and put a nut on the back.. Depends on the brand..

[@sierradk]

Hey Spa Guy! You're Superman to me. Great video. You know your trade. You simple language and explanations. I feel like I'm right there with you. Thanks for a great service.

[@TJ_Romano]

Outstanding educational video. Thank you! Bookmarked your site.

[@adangames2505]

Best how to video I’ve ever seen! Awesome

[@tgainsby3776]

I nearly went out and bought a whole new pump but this viedo has shown I can fix my leak at a low cost. I still have the problem that the impeller just won't come off (loosie left) no mater what even thought the shaft and imeller is turning easily all the way through....

[@UBAYBE]

Whe you replace the shaft seal, does the metal seal sit completely flush on the plastic or is there a half inch gap roughly between the housing and the seal?

[@barbarajohnson7184]

I have a Watkins Hotspot Motor shows a 37334. The Hot tub does not heat and has an error message FLO. I changed the pressure regulator and it was fine for awhile even though still had error msg FLO. But, new problem is no heat. I believe the motor has a noise such as bearings going bad would sound. I see you have a replacement pump. My question is - is this the part I need and do I need any other parts?

[@bknees2]

When reusing the rear bearing, is it wise to apply some grease to it? Also when I removed my stator the rear bearing had some crud as well as the bearing cavity in the back plate. I would assume cleaning the exterior of the bearing surface as well as the bearing cavity & wave washer with some alcohol would be wise?

[@SpaGuy]

The bearings are sealed no way to get grease inside of them..

[@snoman102766]

I’m watching your video and I have the motor apart the stater in the pump has not been disconnected yet but my stater is white. Is that something that needs to be addressed

[@rb3425]

Fantastic video. No questions left to ask after that! My first pump repair! I forgot to drain the pumps when storing and draining through a winter when I was out of the country and the wet end froze and cracked. :-(

[@kylepotter3105]

my bearings are spinning fine but its leaking a lot. can i just replace the slinger and seal and put it back together or should i replace everything? your video is so helpful, i was about to buy a new pump and thought "hey maybe someone has a tutorial for pumps" and you have the exact one i need. thank you so much!

[@OdinsCloud]

This is by far the best video on the subject! What are your options if the shaft is not thick enough behind the thread?

[@SpaGuy]

New Pump and Motor..

[@corstiaandewaard6029]

YOU ARE A SPA ANGLE….GREAT WORK…

[@billwells1818]

So I bought a new 48 pump and I notice the top of the volute housing, the part you removed when you put it in the vice to get to the bearing, has the hole on top that pushes the water into the actual filter. I bought mine and it is the same. The problem is that I need it facing the side. Can it be turned when putting it back together making the hole face the side?

[@SpaGuy]

You simply loosed the 4 thru bolts turn the wet end and put them back in..

[@thestanleycanadianadventur1507]

Very nice job on the Video. I picked up a few tips and will incorporate them on my next Re & Re.. Thank you again.

[@evancheshire8606]

Thank you very much for your videos ... I was extremely frustrated as I fixed a section of flex hose last year and also the stop valve as it broke in pieces when I tried to close the valve, ended up having no issues for a few weeks and than we had the power go out again and temperature below freezing ... by the time I figured it out a few days later the tub was near empty and I just got around to taking the panels off to find the leak starting with my repair and there was no leak there , found the problems shorty after that ... one of the split flange nuts was cracked coming out of the heater and after looking closer the wet end of the pump was cracked and I thought I’d be into a whole new pump... thanks to your video I was able to get the wet end off easily and now I am just waiting for tomorrow to call the local parts guy and it’s gonna be a lot cheaper fix than a whole new motor/pump assembly

[@bfwiii]

Thanks, I just came up with another way to remove a stuck impeller. I heated the brass nut with a soldering iron and it loosened right up! I was just on my way to breaking it up before I tried that.

[@coviedogs]

Hi. I'm curious about weather or not I can reuse my rusted shaft.

[@waynedowding7168]

When you pulled it apart there was a small white plastic spacer with a collar on that was broken, when you rebuilt the wet end and installed it you did not replace this part. Is it not essential to put this part back on? cheers.

[@SpaGuy]

Wayne the idea behind that part called a slinger is to keep water out of the bearing if the seal should leak.. As you saw it just destroyed the slinger and we still had to replace the bearing so my opinion is it really does not work.. I do sell them on the site search for slinger in a several styles.. Thanks, Spa Guy www.hottubpartspofamerica.com

[@danmatian]

I'm needing to replace my Waterway 5hp, 3722021-13 with wet end #310-1510. Seems as if it's an easy install, however, what seal "kit" will I need for this? I'm having a friend bring the wet end to me here in Costa Rica, so, I don't want to get this wrong (no parts here for Waterway pumps). Any help/advice is appreciated. thx

@@SpaGuy so I just installed a new 56 frame waterway pump 230v 2 speed and motor like in the video. Started with FLO/FLC codes after install. Got that figured out however when you kick the motor into high speed it buzzes loud and sounds like it is laboring as it runs for about 5 seconds then shuts off. It shows no code. If you shut the breaker off for about 30 seconds then back on it starts back up in low with either the FLC/FLO code. Any advise? BTW probably the best how to videos on KZbin!

It's almost like he's done this before, lol. Great video. I'm doing this on both my pumps now. Great help

[@thestanleycanadianadventur1507]

Thinking of installing a bluezone spa ozone generator. Have you any info on doing so on a tub that never had one? like where to tap into for the injector, I am upgrading the control centre so control isn't an issue. It's just the actual cut in of the water system.

[@jijoe4257]

Great Video !! I have an old Garden Leisure model 1106 spa.The 2 speed pump has been giving me problems the last couple of years.I took it out and took it to a local repair place about a year ago. They fixed it by replacing the impeller and seal and I guess rebuilt it... I hadn't checked the spa in about a month but when I did that same motor had stopped working( before I did notice the second speed had become a bit noisy). I found your awesome video and decided to take it apart and take a look.I don't trust that repair guy did a very good job if I only got a year out of it.I did notice dried water stains on the wet end.The seal looks new, as well as the impeller, but the impeller shaft is cracked.The motor shaft seems to be falling apart( pieces of metal are breaking off of is...I guess from water getting in??).I measured it and the part numbers are waterway and it has a 56 frame( thanks to all your great well explained videos). The problem I am seeing is the impeller says 4 hp inside, but the wet end has a sticker the looks like it might have shown a 5 hp?? Could the repair place have stuck a 4hp impeller in there and it worked for a bit? but it really needed a 5hp... Sorry about the book I know I am babbling a bit :) Could you give me any advice on what the impeller size should be? I have it all apart in my basement,and live in New York so it is just above freezing...could I run the spa on one pump till I fix this or should I just empty the water...it could be a few days...Thanks so much for any advice you could give. Joe

[@SpaGuy]

What is the amperage of the motor?

[@rorichaney290]

Spa Guy, I bought a used spa that has a Century BN61 pump. When I filled it up and powered it on the pump made a weird noise, sounded like a piece of loose plastic spinning around in the impeller. I disassembled the pump and pulled off the impeller, it spun freely, but nothing 'loose' lying around like I thought i would find. Any thoughts?

[@Nate-ui6yl]

Hello Spa Guy. Great video. Thorough without being repetitive. Everything one needs to know and then some. Now, I cleaned some of the grease at the wave washer in the back end and immediately regretted it. What kind of grease is it, and is it critical? It looks like copper antiseize. Should I use basic copper antiseize, trailer tire grease from my boat trailer, or nothing at all and hope for the best? I'm thinking of just leaving it alone now because you mentioned you want the back bearing to stick in the rear casing and not spin anyways, so maybe less grease is Okay. Also, the old impeller's plastic shaft had snapped off. Any ideas where these broken bits collect in the system. I hate to think they're somewhere critical, jamming up the system, eventually breaking some other internal system. Is it possible it is resting against the inside of one of my jets now? Any way to retrieve these broken bits?

[@Nate-ui6yl]

Also, my motor shaft is quite slim and swollen shapen. I'll try filing to a better shape but worry it might be too slim. I'm hoping for a good seal afterward but maybe it won't work. Fingers crossed. Also, I'm working on a 3.5hp with 3 impeller, I noticed only 1 of 2 bearing retainer screws and clips was installed so only one is going back together. I don't think this will cause issues because the through bolts should assist with keeping things snug but I did notice the aluminum plate didn't spin exactly straight after replacing my bearings. I feel this is because there's only pressure on one side due to only having one bearing retainer screw. Wish me luck that everything is quiet and doesn't leak! You are a great resource! Thanks for all that you do for the online hot tub community!

[@SpaGuy]

The parts of the impeller are outside of the pump so they don't get into the water.. Light wheel bearing grease..

[@ronkloiber]

Great video!! I would put a piece of heat shrink tubing over the shaft but not over the threads once you've cleaned it up, then maybe a bit of silicon over the end of the heat shrink and just a bit on a couple threads where they meet the smooth shaft to seal the impeller/shaft area.. Too bad they didn't design the motor to blow the cooling air out the shaft side to blow any water away from the shaft and motor. Also a disk that would sit about 1/2" from the motor and a bit larger diameter than the air slots on the motor end, to divert any water away from the motor. I have tried to epoxy the nut back into the impeller but only used a 5min epoxy. One attempt lasted almost a year another only lasted a few months.. Next I'll try JB Weld epoxy.

[@atj64able]

i see the three screw plugs on the face plate in this video, mine has a hose going in to one of those. what is the purpose of the hose?

[@SpaGuy]

That is a bleeder line.. It is only used to bleed the air off your pump as you fill the tub once it is full and running it has no function..

[@rosshorley4450]

Hi thank you for your good tips I am a hot tub technician learning it all very fast in the UK have you ever come across an impeller that is covered in fibreglass to the point where you can't touch it it just covers your hands and anything you touch

[@SpaGuy]

I imagine you are working on an Intertek the early impellers look like they are made form fiberglass and they fall apart..

[@peterswatton7400]

Very helpful. My pump is a Bianco but that is a great heads up.

[@Tondog65]

Tub is full and not running. I lift up on the water pipe that goes on the end and water is spraying out through the baffled end of the pump does that mean the wet end seals need to be replaced? I can send you a video of what I’m seeing.

[@walt5594]

Awesome video- Just what I needed to attempt the repair of my Waterway pump-I'm having trouble getting the back cover off the motor. The video seems to be an older waterway model, other than that the damage to mine is exactly what the video shows. I'll call to order the repair kit.

[@johnbryers6684]

Thanks Spa Guy, really informative video. All you want to know to replace or repair the pump. I decided to order the wet end of the pump as the difference in price for seals and impeller made not much difference.

[@JamesWilliams-ot1mj]

Does the switch. Does it sit on top .or in the middle bearing.

[@bret1740]

I have a Gulf Coast LX7000 spa with a emerson TT505 motor and pump. Problem i am having is that it runs fine on low speed (can run all day long) but when you turn on high speed, it runs for about 5 min then the motor thermal switch turns off the pump. once the motor cools off, it turns itself back on. I have proper voltage (230 volts). What could be causing this?

[@SpaGuy]

Most likely an internal motor issue.. That cannot be repaired.. Replacement is the solution..

[@BrotherAngstrom]

Thanks man. Very thorough demonstration.

[@martinrolon1971]

i saw the video and i think is an excellent teaching. i did learn a lot.thank you and keep the good work coming...

[@darylstricker1353]

so got mine together last night, thanks a million for your post it helped immensly. upon rebuilding the pump, the impeller should spin fairly freely in the housing right (minor rubbing from the wear ring?). Initially mine was locked against the front cover upon re-assembly, had to dissasemble, remove the rotor shaft and put it in a vice so i could crank the impeller on further...trying to finger tighten while holding a blade screwdriver is near impossible (For me)

[@SpaGuy]

Hello Daryl, If the threads are damaged or rusty I always thread chase them and I also clean up the shaft and make it as flat as possible so the impeller threads up completely without much effort... Thanks for watching, Spa Guy

Can you switch the 2.5" face with a 2" face since the actual hole size is the same? Are they interchangable?

[@SpaGuy]

Not sure I understand the question but I will answer what I think you are asking.. The Face part that fits the volute is exactly the same the only difference is the threaded part.. I offer the 2 1/2" faces on the site.. Here is the link.. hottubpartsofamerica.com/faceplate-waterway-executive-48-frame-or-56-frame-2-1-2-mpt/

[@MrWookie1981]

@@SpaGuy Thank you that is what I was asking. I mistakenly bought a 2" by 2" and did not realize until it was installed and the coupling did not fit. It would be much easier swapping the faces than pulling out and disconnecting the pump and installing a new wet end or messing around with the plumbing.

Do all wet ends have a wear ring? I took my pumps apart to check for obstructions and there were no wear rings. It also sounds like there is a surge in the heater tube but the motors don't change speed.

[@jfitzmo]

I'd like to re-purpose the Waterway "Executive 48" to siphon/transfer water out of rainwater tank. I've reduced the 2" openings to 3/4" to siphon/disperse water using a garden hose on both ends. I'm curious if the "closed" impeller setup on the wet end and the min volume of water it requires to move won't allow for this 2" to 3/4" reduction vs. an "open" impeller system which most "transfer" pumps seem to employ. Will this work??

[@OberdaReignbeau]

Thank you again. I will order the kit!

[@exploringbc431]

My pump makes a chattering noise when I turn off the jets and it’s not the bearing. It seems like it’s the centrifugal clutch making all the noise. Is there anything I can do to fix the noise that happens every time the pump slows?

[@SpaGuy]

Some pumps make a slight noise to slow the motor down when it goes off.. Is it a slight noise or really loud? If it is really loud there might be w broken impeller or something caught in it..

[@exploringbc431]

@@SpaGuy I find it loud and out of the ordinary when it’s installed and turned on and off…. Impeller is good shape and bearings been changed and are not slipping. I can recreate the sound on the bench moving the impeller back and fourth and seems like the clutch… have you seen loose springs cause noise?

What is the name of the switch on the other end of the shaft where you changed the bearing? I accidentally broke the disc that is attached to the springs. I was changing the bearing at the time.

[@danielfrancois9393]

Hi, great video. I have my motor all back together but when I supply 120V to test it just hums. If I turn the spindle a little it starts up and runs fine. I've had the capacitor tested and apparently it is testing fine. Any ideas? Thanks

[@SpaGuy]

You probably bent the switch in the back of the motor it should be straight.. If it is humming and you hit the pump button and it goes to high speed and back to low speed then that is mostly likely what it is..

[@danielfrancois9393]

I haven't tried it back in the hot tub yet. I will. Thanks!

[@Neophyte1200]

I've watched a few of your videos. All very helpful and informative - THANK YOU. I do have a question on this one. I just took apart my motor and followed your method for replacing the wet end. It was a nightmare getting the through bolts out, but I did it. Upon reassembly, everything seemed good. When I went to start the hot tub, I kept getting a FLO error. (Catalina XL11000 spa.) As I diagnose further, it seems the motor works fine on Speed 1, but when it calls for speed 2, I hear a loud buzz, then it shuts down (not the breaker, just something like the FLO error - circuit board causing a shut down). The shaft seems to be moving freely and I can see it rotating even during the buzzing noise. Any ideas where I went wrong? I did take it back apart again and took a quick look at the switch arm you show that can get bent. It appeared to be sticking out pretty straight, but I may not have examined carefully enough...

[@SpaGuy]

The 2 speed switch has to be bent.. Catalina uses 56 frame Waterway Executive motors and the metal switch in the back being bent will do that.. As long as you put everything else back together correctly that is the only thing that can cause it.. Putting the cable back ion wrong will do it too.. You can open the back cover without taking the pump out if you have room..

[@Neophyte1200]

@@SpaGuy Thanks a million! I'll get back in there and get the switch straightened out.

[@Neophyte1200]

@@SpaGuy One more thing - can you give me any advice on finding replacement through bolts? What are the specs on them? Do you think I can get them at Home Depot for example, or what kind of place?

Working on my pump currently. No matter how much I tried, I couldn't pull the bearing off the shaft using my three jaw pullers. It was much easier to just cut the bearing off with a dremel tool. Ordered a new bearing, now just have to wait for it to show up.

Yep that is the only solution sometimes.

Very good video. The only question i had is. Once the end cap is installed is the wear ring close to the cap or is there an approx 1/8-1/4 in gap which i have?

[@SpaGuy]

The wear ring floats and will move forward when it is moving water using the difference between pressure and suction..

[@rogermeans7823]

@@SpaGuy Thanks for your reply. I thought that was the case but you didn't mention anything about it and your pump didn't look like it had a gap. Thanks for your reply.

Hey, I could use some help with a brand new Waterway pump (BN51) which is malfunctioning. It has an unusual "Wishbone" switch contact for that centrifugal hub. Is there any illustrated guide to replacing/adjusting that wishbone switch? I must have knocked it out of alignment when I disassembled the pump to rotate the wet end 90 degrees. I've been shifting it around with a screwdriver to try and get it lined up with the hub just right, but it seems like when I get it able to start, it starts for a few days and then randomly gets stuck unable to start again. Should I replace the wishbone and how can I make sure it is aligned properly?

This is a great video with lots of info. Thanks for posting it. So we replaced the bearing and seal on our wet end, put the pump back together and reinstalled it. When we added water to the spa, the pump leaked at the face plate. We thought the o-ring looked alright so did not replace it. In your video you do not replace it. We are waiting for a new o-ring to see if it solves the problem. Any other suggestions?

[@sierradk]

Louanne Gilmour - I know this old news, but for other readers here's my input... I used silicone grease (that's grease, not RTV) on the old o-ring prior to re-using it. No leaks.

I just replaced the bearings and seals on my pond pump, which is very similar to the pump in this video. One of the differences is it's a 0.5 hp, 1750 rpm Baldor motor. It was making a chattering noise, and after the bearing/seal replacement (which were still in good shape), it's still making the same noise. At the 28:00 minute mark you commented about the rear bearing spinning in the housing. I think that might be what's wrong. Can you give a little more detail on what you do to the (bearing?) to stop it from spinning? Will replacing the wave washer help? Do you have the washers available?

I have a older Nordic 2 seater hot tub Belle model and the pump is now loud. I am assuming the pump bearing is bad? I haven't opened it up and wondering if you are familiar with this model, the pump and what kit I might need to repair. I think it is a 1 hp motor but not sure and runs on 240/120 currently running on 120V. suction max flo 80 GPM. 32/12A 60hz. I would be willing to buy on your website. Great video and I prefer to work on it myself if possible.

My motor beyond repair. I had a 12.2/3.8AMP motor in my spa but I found a 16.0/4.5 AMP replacement motor the other specs are exactly the same. Can I replace the old motor with this one or would the extra AMP burn my motherboard? Thanks a lot in advance!

What causes my wau400-11 spa pump to hum in low speed and I get a FLO Error message but it work when I turn the jets on to high speed?

[@SpaGuy]

Probably a bad switch and there are no parts.. You will need a complete pump.. You need to check the voltage for the low speed system.. Thanks, Spa Guy hottubpartsofamerica.com/search.php?search_query=wua400
