No Heat Stuck Circulator Pump HVAC Repair

- I am on a no heat call. I check the radiant manifolds and hot water coils to blower units and everything is cold. Further inspection I find the circulator pump is seized up and jammed. Raspberry Jam! Yet after removing the motor and piling it up I get the bearings to start moving freely and I reinstall the pump.
Whoever did the original plumbing work, Great job!
They did I give them respect. That company went out of business years ago
u saved that antique pump from scrap,wow now that pump is faithful to u for the rest of the life.
Good to see someone actually fixing something instead of replacing parts. I put tags on all of the motors on the units I worked on documenting when I oiled them. I tried to get them spring and fall. Some systems circulated chilled water in the summer too so they ran year around. Others were shut down in the summer so they might stick if they weren't lubed at shutdown.
Have to admit I was skeptical. Nice job. Those motors start to feel like 50 pounds when attaching that coupler. Been there. Lol.Good video.
I wasn’t sure at first yet have had success recepricating these motors in the past. It took a bit of work then it was moving as if I replaced the bearings
Let the home owner know about equal run time on those circulator’s. The best way to keep them in working order is to run them, when they sit to long they will definitely seize up. Did you say if it was a glycol or water heat system, we know what glycol can do if it’s not maintained. Giving them a oil can and a schedule saves emergency calls and gives the owner knowledge on how MAINTENANCE is important! Good job on freeing up that circulator!
The homeowner doesn’t do any maintenace that’s my responsibilities or someone from my company. We swap the pumps over every year. This is water only on this side of the system. There are snow melt sections off plate on plate heat exchangers. I show more of this system from yesterday’s video when I do some maintenace on the house. I even test the pump
@The HVAC Hacker excellent save I think you are officially the top B&G neurosurgeon this side of the Mississippi
Calling Doctor Hacker we have a down booster pump
Just an idea - for replacing the motor on the G&G pump: if you take 2 pieces of threaded rod or bolts and cut the head off to the proper length making two dowels - screw them lightly into the motor housng and use them to hang the motor while you as hanger. Use fully threaded peces it will help keep the motor from slipping off when you hang it. Just a suggestion.
Dude you're just like me nothing's broke until I say it's broke. Good job on that pump
The oil just dried up. These B&G pump motors are tough. I even have a video where I was there to swap some filters and the pump was purring along.
The HVAC Hacker I have a few of just the motors. And one whole B&G pump All mine are super old but they still turn 20 years old maybe I got them out of my friends basement. Two of the motors I have are the Taco version of these. The whole complete one I’m going to try to reinstall when I get my wood boiler for one of the zones. And maybe I can find the rest to my other ones.
I have some old b&g pumps still running out there. They will last if they are taken care of and oiled.
The size of those copper pipes is impressive, must have cost a fortune! Nice environment to work in as well.
I used to do stuff like this all the time. More times then not I would be back again having to change the motor. I just don't trust these repairs anymore. It might last a few hours or a few years either way the damage to the motor has been done. I hope it last you many years
A coworker was in the house this week for air in one of the radiant sections. Told me it’s still pumping away
If the B & G pumps are oiled during the pm checks that may have prevented it from getting stuck.
And people call me crazy for repairing a 15 dollar desk fan i bought back in 2001 for lubing it once a year and still works like brand now today.
Motors last if taken care of. Why not oil a motor can't hurt and it might be better than most motors built today.
Sad part is I just ripped out a working 34 year old ac unit at my dads house. He wanted to upgrade. It broke my heart since that old Trane still has lots of life left. If I had a garage that needed ac I would reinstall it
Nice repair. Love the disclaimer in begging to keep trolls away. Especially about the sales LoL
I might be throwing some kindling out there. Yet I am sure many were screaming at there screens that I am repairing instead of replacing. I wasn’t sure at first if I was going to free up this motor yet had to try. I have gotten many of these freed up and they are still running many years later.
@@thehvachacker man people are always going to have a better way or should have done this. Screw them. That was a quality repair and no one can predict when that motor will fail. Plus that looked to be a redundant set up (back up). Even better reason to make a repair.
Exactly if one pump needs any parts just switch which pump is in operation.
The only reason why I wouldn't repair something like that is because our customers want that guarantee.
The pump could easily be taken out of service and other pump can operate till a new motor arrives. I explained what I would be doing with the pump with the homeowner. They were happy to only pay labor on this trip. A coworker was in this house a week ago cause a grundfus pump in the attic on a radiant loop went down and this pump is still purring.
Nice vid . I probably would have left the back up pump going and taken bad motor to motor shop for bearing replacement. Wouldn't be as bad of cost on complete motor change but would insure it won't stop working down the road. I feel motor bearings are a shot in the dark sometimes. I've had motors run and you scratch your head wondering how in the hell is it working and then have bearings go out when a week before they seamed just fine.
It’s a crap shoot yet I find usually these motors chug along for years after this as long as the windings didn’t suffer too much of a beating from the over heating.
it's all sleeve bearings, they often seize due to oil waxing and sludging, with minimal to no damage to the shaft nor bearing surface, you have the right idea taking them apart and cleaning it up though. often good oil working them free, then over-oiling a bunch to flush old contaminates out will work.
this doesn't work on small motors like bathroom exhaust fans and others without "oil ports", because they're mostly "oilite" type bearings with no way to retain and stay lubed after the impregnated oil from within the bearings are gone. oilite, was one of the good things from "Chrysler"
Those flex wrenches are the greatest!
I do like them. Sometimes the ratcheting end is to fat into some spaces.
I have a 9/16 that gets stuck all the fn time.....gotta hit it to free it.....& it happened weeks after I got the fn set......crescent makes a set of 2 that's a whole set of ratchet wrenches......they r food to have but yeah,like the other wrenches they r way too fat for a lot of spaces.......
I had a craftsman 10mm ratcheting wrench fail it got stuck I dunked it in hot motor oil left it in for awhile then tried to move it and the internals broke. Took 3 years to finally get sears to break down and give me a gearwrench 10mm with a flex head. It’s the only wrench the manager would give me, wouldn’t open a set to replace my wrench. That was my first flex head wrench, then I bought a whole set.
Squirt some oil in the bearing holes, spray some WD 40 around where the shaft come out and they all start right up.
These motors are tough and 90% of the time stay running after freeing up. I wish I could say 100% yet as a gambling man I took chances with smaller odds
yep, majority of the time it;s simply the oil broke down into wax, gum and varnish causing it to seize. typical lack of oiling or wrong oil type on a sleeve bearing motor :)
throttle bottle I buy the zoom spout oil at the HVAC supply it’s turbine oil. But had a thought what about air tool oil??
little skimpy with the turbine oil i would dump half an ounce in the impeller transmission and be sure to soak the wick in there.
pull the motor out of its cage. there are two screws holding spring steel covers over each bearing. soak that right up with oil. even that end play looks ok. i might stick a washer in there if i was rebuilding it
7:14 Good to see you're testing before touching. You should also test between live and ground. If the neutral wire was broken it would show zero volts in your test but it would still be live and would find a path to ground through your body when touched.
Always even if I have the power off on this pump and on for the other pump need to be safe.
it only hurts a little ;)
then again I'm crazy and wire live frequently, I always have.... well only in buildings I know are 120/240V, with 120V max to neutral/ground, because becoming a 277V to ground "conductor" is no fun and hurts, so you best know what your dealing with first.
No load so this would be just a sting. It may sound funny but when drenched in sweat even 24vac can be a WTF! Throttle watch that wild leg. Most have wired hot or accidentally cut a live wire. And yet Klein says they will not protect me from a shock? I never felt it yet my needle nose pliers either have welding marks or cutting blades burnt away.
that is a impressive looking system.the B & G are just hard to kill. if you have a system to require something that big.
B&G makes solid pumps. At first I wasn’t sure if I was going to bring this motor back to life. Just had to try since there is always a backup pump for this house.
I would do the same thing with a back up being that easy. if some one oils it right it should go for years yet.good call sir.
Hack-Man to the rescue ... Good vid , brought it back to life ...
Perfect thanks for clearing that up.
Please call me Bill, not sir. Yet if you check this video out you will see why the homeowner won't do anything himself. ua-cam.com/video/1nlMFJ7kSeU/v-deo.html
Love the videos, I always learn something new in each one. Thank you.
I worked in a heat treat plant. Old surface and lindberg's. We switched over to the newer pumps and they were junk. Quench oil is hard on the new pumps.
It’s hit or mis with the the newer pumps. Many the seals on the bearing assemble weep brand new. What do you think is a better oil?
@@thehvachacker no. I think it is worse. High temp with the quench oil made them go out faster.
What oil did you find helped the motors run better?
u and me are same even tough i repair and rebuild pcs but u r videos are awsome,love from india bro.
That looks like the old GE motor pumps.... Ha Ha. Great video.
No way did I want to send this motor off to pump heaven. All it needed was some erl!
@@thehvachacker great job. I wouldn't either.
The HVAC Hacker I had heard from someone that they had one of these last them 41 years!!!! Wow
Korea Hvac 기능공~응원해주세요~
잘보고갑니다~^^
Hi Korea
maybe some cardboard under the pump to keep from scratching or chipping the tile floor or getting in the grout.
I should of, didn't damage anything but better safe than sorry
Mr. Pump would have taken the motor apart and cleaned up the journals and the sleeve bearings and replaced the wicks.
Also oil the bearing assembly as well as the other pump. Motor mounts looked ok but I would have installed a
Spiralink Coupling.
Same thing I would have done. If for nothing more than to see if I could get it working again
Customers are happy to pay an hour of labor vs 500 for a motor. Plus I had a repair on a separate boiler in the garage to leave the pump running and come back to monitor
I would have changed it right out . You might get it running now,but when it comes back in at 2:00 am ,you’ll wish you did . Good job anyway bro ! Also did you change the wicking in it as well ?
I found something in the video to actually, complain about!!!!! you wrapped the ground wire around the grounding screw head backwards :))
I am surprised only one thing most have a punch list! Hahaa! then the screw head kept pushing it out of the way. Pinch it and it goes nowhere
lol, clockwise wrap for right hand thread screw bro... elechicken background (as AVE says) helped, but as a younger man I discovered such before being taught =p
no I am not god nor claim to know all, but I love to learn hands on and from others directly or indirectly, every day is a learning experience and they day it isn't? is the day you gave up to the great pressure and/or their drugs ;)
they're quite often the easiest way out of many situations..................
If only they were legal in nj, as they are in Canada. Trial and error with lots of hands on is the best way to learn.
Now I need to finish watching this a video my wife rudely interrupted me from watching to buy a mattress for my daughter.
I want to see if that Ridgid turd smokes or can operate on That larger battery. Is the flux signal to the confuser the same as field excitation on a generator?
Also I would not have used channel locks (pump pliers) on the motor shaft. If you can't turn it by
hand it is to tight.
Woulda done the same thing if it were me. Can't break it more.
That pump is still running. Plus I showed the homeowner how to change valves Andy power up other pump of it ever does stop. To get heat going until I can get out there
it just needed a little 3 in 1 oil!
These motors usually last forever if oiled
Job well done
Thanks Roy!
I would have "Fired" you for not changing that motor!
If your serious I feel bad for anyone that works for you. It is always better to repair over replacing. Now the backup pump Sounds like I might be rebuilding next year since it was noisy. I ordered the whole rebuild kit for the bearing assembly, mounts, and coupler to have on site. Since I left the pump B I repaired as the main. I don’t believe in throwing good stuff away. I do that too often with filters. Changing filters that look new during PM’s.
Done that lost of times guess what there still running so good HVAC :)
Jimmy Berry your a f-ck!ng idiot. Who in their right mind would replace that motor when there is a back up pump/motor??? Plus its a B&G pump. Anyone with any kind of experience in the field knows those pumps/motors can take a whooping. That's why you see 30 or 40 year old B&G pumps still running. That's a scamming type of replacement with it can be fixed and you see big home so must mean big money. So I'll charge the guy thru the nose......... Dude move on!!! You lack experience and you sure wouldn't last long with this caliber of a customer
Yet it ran smooth and quiet and pulling less than 2 amps.
I've freed up many motors over the years (sleeve bearing) that all seized with minimal to no damage to the bearing surfaces. the oil turned to a waxy sludge and seized after the last run and cool down or off season. I pull the actual motor apart, clean(carburetor cleaner,steel wool,emery cloth), inspect the shaft and bearing surface, if it's not scored and gouged, oil it good and away she'll go for years more if oiled! you can often just oil and free them up and they'll be fine (over oil a bunch to flush out contaminates as they loosen)
when dealing with slum lords, you do things as low budget as possible and they often run 5+ years without ever seeing oil again, seize repeat ;)
Changed many B&G 100s can tell you motor won't last long , should have been replaced . 50 year retired plumber ! They are not pumps they are circulatory.
umm "circulator pumps" is the proper term, because a "pump" is what they are and the design is that used as a circulator in a closed system or open.
semantics =p
They are circulator pumps to if not a pump then what is it. I am sure anything moving air or water falls into a pump category.
@@thehvachacker 100% correct, the word "pump" is a broad term ;)
You didn't indicate oiling the other pump. Should wrap the ground wire clockwise around the screw, to be sensible.
I oiled the other pump didn't include it into the video, Yea I hooked the wire backward around the ground. oops. which is why the screw pushed it back out.
hooray for "stubborn bastards" might have jumped motor when out and let it run a bit to rule out immediate failure but just a quibble
I did let it run alittle more than an hour before I returned to check on it. I had a small boiler repair in the same house
congrats i thought that motor was toast
I thought it was also, yet had many instances where I have freed them up and they keep pumping for years. Then the opposite can happen where they only pump for a few weeks.
Good disclaimers :)
I enjoy repairing instead of replacing yet have already been told I am fired in a comment for not replacing the motor.😂
@@thehvachacker Enjoy the haters :)
Can't let them get me down and I love what I do for work 80% of the time
Nice Repair! By the way, can you tell me the reason why in the US heaters and boilers are often apart? In Germany we normaly have all in one Units.
Usually the boiler heats the whole house. I apologize I spend most of the time when doing residential work dealing with the mega rich. So the two boilers in this video do 27 radiant heat zones and 8 hydro coils. Basicly the customers are heating there floor and air. The forced air helps add heat to the spaces. I am not sure how your heat is in Germany yet my in-laws in Poland have a coal/ oil boilers that heat water and gravity heats the radiators. In America boilers usually are heating baseboard or radiators until we get into the mansions here. Then we start dealing with driveway melts, radiant heat, with forced air heat.
In Europe are typically wall-mount condensing furnace/dhw combo units (in small apartments), the same for newer centrally heated houses, all via radiators or underfloor heating. For systems installed in the last 10 years, weather controllers have become popular that control the feed temperatures via a curve according to the outside temperature, controlled via mixing valves and sensors (separate zones for radiators and underfloor), they are more costly so not everyone can afford those.
Some older systems that had oil furnaces were just retrofitted with newer more efficient boilers and these weather controllers.
Also popular (in more rural areas) are pellet burners (due to state subsidies and supposedly cheaper energent price, though the maintanance is much more costly) and some people still heat their house with firewood and small stoves, due to being poor...
Also solar collectors for heating domestic hot water are very popular, you see them on almost every house, heating a separate dhw cylinder (200-300l for a single family unit) with a coil for additional heating from the boiler. Some houses have a combined heat store cylinder that can be heated also via the solar collectors (in this application typically vacuum tube) that can heat the whole house via solar only when there is enough sun. (The cost saving rationale is quite questionable unless the local energy prices are quite high, but our states "help" that by additionally taxing fossil fuels and subsidizing these "renewable energy" systems)
@@brainndamage I'm actually going to install thermal solar water heating system in my home. They cost a fortune to buy a whole kit. Its better if you have some mechanical background and do it yourself (DIY). The solar thermal water panels can be $1000 or more panel. Which is crazy cause i can build them for less then $200 per panel. Can knock out your water heating usages from 60% to 80% less........
One reason some people install separate water heating systems and heating system is cause the DHW flow rates. Some homes here have very high end baths and shower systems. Require more then 8gpm or more. Combo units wont do that
Gonna bet ya hear back from that one😉
I will hear back from this house for many things this winter, excluding this pump. There is always something breaking when the heating and hot water recirc has over 30 pumps.
@@thehvachacker wow! 30 pumps ,well at least you'll have plenty to choose from to swap this one with in a pinch
Most are taco 007 for the radiant and hot air coils
Was there yesterday still running smooth
Over oiled LOL next you'll be replacing the coupler and motor mounts (over oil a B&G motor and the motor mounts will sag and the coupler will break)...TECH!
I did flip the motor over to allow some of the oil out before reinstalling. There is always a backup pump on the system if anything happens to this motor. Something is going to break in this house over the next few months with over 30 pumps.
@@thehvachacker Grow up ....you know (or should know) full well that over oiling that B&G motor will cause problems...do you think you're the only person on this planet that knows how to do what you're pretending to do?!?! The "Hacker" is strong in you....TECH!!!!!!!
the wrong type of oil is what eats the rubber fast, know as clowns using common motor oils full of detergents and other junk.
sent plenty of all original 1950's units sent to the scrap yard due to magical "energy saving" system replacements, the rubber was still solid, couplings never broke and always over oiled.
the bolts all had unscratched factory paint, date codes and plates all intact and oil puddles on the concrete floors underneath, they just fell pray to the mostly scam "energy saving" spiel.
I always thought that tin trays were first designed to catch all the leaking pump oil
Check the capacitors?
The cap won’t stop the motor from turning or jamming. Yet will give motors issues running. These are tough motors, usually don’t have cap issues. I see to many techs replace this pump over a broken coupler
That sounds like a truck engine lol
The pump I didn’t work on was loud. I did oil it when I attempted to oil the seized pump to see if that could get it to operate.
@@thehvachacker it sounded like a truck engine when you started it up I don't know if it came across lime that but it sounded like it to me.
That was pump a which this year is the backup. I screwed up the sound somehow trying to edit on my iPhone. The pump started and then a few seconds later you hear the pump chugging. The pump that was seized and I freed up was very quiet when I go it started. I had the phone resting on pump A when I put pump b back online mabey the sounds traveled inside the pipe?
he did not lubricate the back bearing nor the other pump unit, my kind of service person.
I was oiling both sides of this motor. And the bearing assembly. I added oil to other pump it just didn’t make the video. The camera was sitting on the other pump while filming
Patients and persistence...nice repair... what a pain in the ass for access... hopefully she pay you to use your zoom spout on the other ones
You mean I was suppose to charge for the zoom spout. Oops. I only billed for my time on site. Which was an hour for this boiler pump and an hour working on a different boiler. I oiled the other pump while there since I think someone on there maintenace forgot to oil the pumps
More along the lines of the customer saying “hey i am a dumb ass for not getting my pump lubed regularly and I would like to pay you, since you are here, if you have time that is, to lube my other pumps”. And then you whipped out the spout and went to work and charged her...
The worst part is this house gets annual service twice a year.
Put some heat on it
Oil and moving around the motor got it moving and running.. This was a year ago.
hacker u should chang out motr let maint man oil ull get call bk all for nothing like steve lav sez wen it doubt change it out
That pump will run for many years to come. I am set up to do a filter change on all the air handlers in this house when they come in. I am in this house at least once a month fixing something. If the motor is overamping I make pump a the main pump, disable pump b and get a motor and coupler.
