- Crankshaft pulley broke, call it a harmonic balancer and it has snapped in half or the outer ring and inner ring are no longer attached. Well look no further. I show you how to use JB Weld to fix that crankshaft pulley so it's like new and it will only cost you $10 bucks.
Symptoms of a Bad or Failing Crankshaft Harmonic Balancer. ... Its purpose is to absorb and reduce harmonic vibrations from the engine as the crankshaft rotates, as harmonic vibrations at high engine speeds can cause accelerated wear and damage to the components.
The purpose of the harmonic balancer is to reduce engine vibration and in many cases, serve as a pulley for drive belts. Harmonic balancer's do have many names, though, such as damper, crankshaft pulley and crankshaft balancer, among others.
One of the first symptoms of a potential problem with the harmonic balancer is engine vibration. The harmonic balancer is specifically designed to absorb harmonic engine vibrations as engine speeds rise. ... The shaking will become even more pronounced, and therefore dangerous to the engine at high speeds.
A crankshaft pulley powers components on the crankshaft. Crankshafts are responsible for driving the car wheels. Crankshaft pulleys transmit mechanical power and torque, or the force of motion, through the pulley system to additional car elements, such as the power steering pump and alternator.

Thank you for this video.. My family is tight on money and mother's harmonic balancer just broke. Gonna give it a shot. Thank you so much
How'd it go?
What actually happened was the pulley itself on the ac compressor broke and wasn't allowing the belt to spin at all. So I just put a shorter belt on. I got no ac. But at least it runs
@@rkchaotic1973 good chance I'm about to run Into the same situation. Thanks for the response
I'm pretty sure my outer ring rotates slightly from the inner ring on my corolla (the timing mark jumps around when I try and time it), so I put the timing mark on the ring that has the crank notch in it (instead of the one that rotates). I've never had screeching or anything happen, and it has passed smog, but if that inner ring is still rotating independently, will that throw the timing off?
Jb weld is heavy enough to throw out the balance, right?
Let’s say I turned the harmonic balancer with a socket wrench turning the bolt ; how would I put it back in the correct position?
@bundysgarage Is the repair still holding? Im doing this but also going to have a person weld the pully back on because its a discontinued part. Does your car shake at high speeds?
Thanks for the video , I have a important question ? How do you troubleshoot a crankshaft pulley that is not aligned with all pulleys on a 2014 Honda Civic ex 1.8
There’s likely a timing notch on the ring that lines up with the key way on the middle part.
Gluing that is a huge mistake, that was glued at the factory BALANCED PROPERLY. Those are the little holes, it was drilled until properly balanced to avoid vibration. You are going to glue it at it will be UNBALANCED. It doesn't matter where it was, they rotate when they get loose not knowing the correct position...
It’s going on a Honda dude not a big’ol hot rod making 1,300HP.
go to a tire shop and throw it on the balancer. where it tells you to add a weight, drill out the opposite side
I have one that that technique can’t be done on, is there a real strong glue to do it??
Same thing just happened to mine on my 1990 Honda Prelude. Really sucks because they basically discontinued almost every part for my car. I've been having SERIOUS engine vibration and I just now went to replace both belts and BAM pulley slides right off... I'd try the JB Weld fix but only temporary. I've used JB Weld on many other parts with no issues but the harmonic balancer is meant to keep vibrations to a minimum because eventually, at higher speeds anyways, internals will get loose but hey regular city driving I don't think would mess it up. I've got a total engine rebuild kit and the motor has 300k miles so I'm not really worried it's just my daily driver is currently in the garage where my prelude needs to be for a frame up rebuild
Very interesting! I will need to do it on an old car where it isn't possible to get a new one.
So how do u get the pulley off?
So how long did it work for and I'm having no problem with the way my explorers running it fell off like 2 days ago I looked down through the engine when I was washing it off and I could notice there was something hanging there and in there and I sprayed it and my harmonic balancer was on the ground but my vehicle is running super good still super good still having no problems should should I try and do that until I can get it fixed or should I just leave it running the way it is cause it's doing just fine please get back to me Thank you good video
How long has this lasted??.
Can you put the PN of the JB weld in description?
Yesterday I had this issue, just bought a new one at part store. So the old one robbed from another parts car I want to repair it and reinstall back.
Let me know how it woke and long it lasts.
BTW,
I had it like this and could Not figure out why the battery drained over night, and was because it was imaginable and charging in day was easy but at night with lights on.
It would spin-Freewheel and the enging would cut-out" due to lack of voltage, so FYI there on this point also.
thx
My pulley’s rubber simply MELTED. Dying to find a matching rubber. Suggestions please?
It will work fine for daily city driving, its when you hit the freeway and it needs to absorb resonance, that will eventually cause inner engine damage. Its a great fix until you can get a new balancer.
He just want to sell the car quickly....BUYER BEWARE!!!
You got a good one sitting right there...USE IT!!!
I think he fixed it because he got the wrong one at the junk yard😂 it looks like it’s from a non power steering model
Need an answer on this fix, do those two components move individually at any point? This seal kinda bonds them together if I'm not mistaken. Can someone clarify this please
No. Earlier models had a solid steel piece but newer models had the rubber added for better damping or vibration elimination. But with all things plastic or rubber on Honda's and probably every other car for that matter, it dries out from wear, heat, abuse, etc... then detaches eventually. For instance my older 1988-89 Honda Prelude had a one piece crankshaft pulley . My "newer" 1990 Prelude has an "upgraded" 2 piece pulley with the rubber ring inside. Technically its 2 piece but for demonstration purposes or whatever I call it a 1 piece because it functions as a single unit but is made from 2 pieces so to say but no they're not supposed to function individually. If they do that means they are separated and need gluing, epoxying, JB Welding back together. Oh yeah, just in case, use a high temp/weather resistant/high strength epoxy or whatever and try not to use too much or be sloppy like this video did because it throws off the balance and it'll end up wobbly and or causing vibrations
testing it out on my 740 wish me luck people will update u on result
I did that on my bicycle when was 12 years old .. (old school) but after all, I learn ways to take measure at safety first. On vehicles runs a bit power since a each torque.. I think would be better read manual book first, how many horse power runs on your vehicle.. if it’s says 4-6 hp horse power so, you can add a bit J-B or even gum by heating on high temperature .. but to avoid accident to your serpentine belt comes out when you’re on 75 mph so your families and friends will waiting you at home .. or at least your pets.. I believe safety first..
i will try that
I am going to tack weld mine back together just so I can steer it on my trailer. But it's getting a new crankshaft new bearings . timing chain and a new harmonic balancer
Problem with making it solid is its NOT going to absorb the vibrations at high rpm and cause premature failure of internals 🤦🏽
It’s still running so there is no “premature” wear of internals. It’s on a 4 cylinder car so it’s fine. Now if I was working on a Bugatti I wouldn’t do this. It’s done cause you can’t afford a new / used one or they are obsolete.
I agree with this comment, $80 savings is not worth the cost of bearing replacement or even crankshaft seizing. And yea my man PREMATURE WEAR of internal parts! This is shade tree mechanic bs right here that balancer needs another balancer lmao
@@bundysgarage.
Man , harmonic dampers are discontinued for my chevyvan, was looking if i could repair the damping part for the pulleys (got v belt) . Saw a felpro repair kit , might use that now that i know i can just debuild it , stills in once piece so i can mark it proper too. Cheers not gonna spend 700 for a serpentine one that would require me to change every other pully so best i service with new glue. Cheers man
Thanks for the idea, I will try with the chevrolet voyager. There's no new part available
Worked on the farm truck so far and it has been a week. Also did it still on the motor. Its a farm truck
Yep saw the car the other week and it’s still going strong for all the ppl hating on this video. They think it’s some highly tuned Bugatti engine or turbine from a turbo that has to be dead nuts on, silly people.
Still going?
I haven’t seen it in awhile but the owner would let me know if it let loose
My farm truck is still going. Take to feed store and work the farm. Have not noticed any vibration.
Hi, I would like to know if the repair with the JB has lasted, is it still working? When I was young, I repaired the case of a Ford Mustang with JB Welder. The belt tensioner screw would not hold any longer. I willed up the hole, taped and the repair lasted for many years, the life of the car!
yep still going strong
@@bundysgarage Great to hear that. My other SUV needs the same Harmonic Balancer repair. Thank you!
So how do you get a crankshaft bolt off without the pulley being on it? I am rebuilding a 2.2 liter Honda accord, spun the engine to make sure pistons and rings were okay. Now I can't get the crankshaft bolt off. Help!
Try to hold the engine in place with the flywheel.
@@bundysgarage I did like you said and tried to hold the engine in place with the flywheel. It tore the bolts off. Oh, well. Can't believe how easy this thing seizes up. Unreal! Any other suggestions might be helpful if you have time. Thanks! Appreciate any advice you could give me. Peace out.
@stangmaster 2 Engine is already out of the engine on a stand. Can't hit the starter. Never done this before. Retirement project. But I got the darn thing off by putting an iron bar against the bolts at the rear of the crank at the rear main seal. Worked every time. Couldn't rotate it ccw because it needed anti-seize on it. Couldn't get it off without it. Had to go cw and it messed up my balance timing. Always something with these things. Everything's a big deal with these junkers. Old cars with rust, and still older guys like me trying to fix them. Rather comical actually. Thanks for the tip.
@@bundysgarage Dude, worked! Thanks man.
That’ll survive a good few clutch drops I’m suuuuuuuurrrre
Hell ya will get me to work for the week till I get one next week appreciate it bro
what are the symptoms of one going bad? does it make the same sounds like the tensioner pulley?
The drive belt will continually skip due to the ring around the pulley no longer fully spinning with the crank shaft. A loud belt squeal will be heard. Sometimes it takes a larger load on the drive belt assembly for the squeaky sound to occur (AC on, power steering engaged, engine in drive but car not moving)
Yeah I had a bad tensioner pulley on my old Celica. They were notorious for bad tensioners in general, something reported on their TSB. Usually when it is colder out and you first start the car you can hear quite a loud screech. But like the other guy said you will get that squeaking from heavier loads to the engine, especially when turning all the way to the left or right. When it is warmer out and you use your A/C, like mine, that belt will keep squealing and squealing. It was very annoying and I did end up fixing it myself eventually, but I don't recommend any belt dressing as a "fix." Belt could slide right off the pulley
Really bad belt squeaking sound and really bad engine vibration when in drive. That was my case anyways
Yea, I had the same and it sounded just like a defective tensioner pulley. You can easily test it, take the belt off and see if you still hear the noise.
Wear gloves. Don't touch the epoxy. Coating both surfaces is ideal for such a high strength application. Wish you had video of your results instead of just hearsay. Thanks for the info! Liked. Subscribed.
Saw the car the other day, holding up fine.
Hi do you happen to be familiar with 323 mazdas? I have an 87 that has a wobbly crankshaft pulley... I can not find one the oem... could ya point me in the direction of a aftermarket company that might be able to help me?... awesome videos keep em coming thanks
What’s the VIN number?
Jm1bf2226h0517798
Replacement part E350 6.8 L V10 is obsolete so this is my only fix. Still feel like there should be some rubber in there. Can a girl use that make a gasket shit as well?
No, RTV will not work the same way. You have to use some kind of bond like JB weld or quick steel
That is what i looking for in youtube..besides this method, can we tack weld the pulley together?Tq sir
You could try. Just don’t let the weld interfere with the rotation of the pulley.
No. The rubber in between serves the purpose of absorbing the vibration from the crankshaft. Welding it will negate this. Jb weld also is not a very good idea.
This guy is what could make this place a better World. Thanks Bro
Would it still do it's job at absorbing vibration If you use JB weld instead of a rubber ring?
The vibration from that tiny balancer, you are never going to feel.
Nope
His shoes daddy so cute,,,, luv
I bought a truck and the outer piece of the pulley was weld. The pulley is not even turning straight. Just replaced it for a new stock one.
Would’ve tried this method if my outer ring didn’t completely come off while I was driving. No idea where that thing went lol
Oh jeez
Hey there logan did your engine present any issues after it snapped or was it all good post shaft replacement
@@alonsosanchez381 All seemed good after replacing the harmonic balancer. Still driving the car daily
@@nMURKv gotcha mine snapped off the other day, made it home, got a new balancer and looking to install it, would you say it’s a tedious replacement process , I was doing my research and the part that looks daunting is making sure that it’s lined up properly to how the old one was lined up, and making sure it’s mounted properly seems like would be the most delicate part of the installation
Reminds me of what I deal with when I'm doing a repair at 6:31😆
kids are cute :D haha
Yep she is still going
I just did this on my 60k Porsche 911 thanks!
You have a 60k Porsche and didn’t just buy a brand new balancer?
@@mansandem bro for real. Like wtf? The balancer couldn't be more than 100 bucks but you have a 60k porsche? Bruh sell the car if you can't afford to buy oem parts for it.
@@Drpepmazing yeah well on a '96 Honda Accord 2.7l v6 the "damn" Harmonic balancer is any where from $350 to $517. And Honda no longer makes the part as most parts on this engine are discontinued!
@@TestTest-up8vc get a refurbished one then or get one from a pick and pull and it won't cost nearly that much.
Update this dudes pulley flew off and caused a major car accident he's in federal penitentiary facing the death penalty by electric chair
Armonic balacers must absorb vibrations, they work like dumpeners in the suspunsions. I hope this video it's an April fish...
Exactly it didn’t work!
What if just glue it with rubber glue...like polyurethane or window weld? Will that works?
If not why not just weld them together?
nope that kind of glue is so weak and you can regret it so much! best option is just to buy a new one or a good old one! that's it no fix!
That's fine if you wish to drive that like an old woman, but under speed and heavy load, you could be asking for big trouble !
U make me laugh using your fingers 😂
So did it work long term?
Yep still holding up!
@@bundysgarage Cool!
@@bundysgarage my pulley did the same thing as the one you have if came off I put it back on car still runs do I paint a line on it now so I know
This will cause vibration.... it needs a rubber type bond to reduce impact of other pulleys tension on the crank. I just wouldn't.
Yo lo hice con resina en lo que me llegaba la polea que compre en ebay.
How much was the pulley on eBay?
@@bundysgarage 35 $ New
@@talegasvil 35N$ : bueno y barato
👍🏻
Install new crank shaft pully in a 1993 toyota 22r
Tried it, put on the car and when that car spins it flew, didn’t hold that force at all… The product hardened like steel but have no flex on the rotation of that pulley, just didn’t work!
Maybe you didn’t let it dry long enough.
Dude i swear every previous owner on my 20 year old accord mustve done stuff like this everytime something went wrong on it instead of just doing it the right way or getting someone else who WILL do it the right way. Now im trying to save this gem of an engine thats been through alot clearly in its short 144k miles its seen. If you cant afford to fix it, just wait untiil you can. I guess i understand if you only paid 200 for yours but some schmuck is going to watch this and then go completely diminish the lifespan of a perfectly good car. Go to pull a part and learn how to take it off on a dead car and then pay next to nothing for the part. Not only is it much easier to afford you get a practice run or two before attempting taking off your own. No matter what itll be 100000 times better than this 😳
Ok Shady, in these hard economic times people don't always have money to fix it properly. This repair was done because the harmonic balancer was not longer made, what suggestions do you offer if it's no longer made? People are not going to spend hours at a junk yard looking for an old car for some obscure part. There is nothing wrong with this fix, it's still running to this day! It doesn't hurt the engine at all. Guys on here are so silly. If it was some high performance, high revving engine, no I would not do this.
Expect this from a guy named Bundy.
Hahaha... It's just a harmonic now... 'cause it sure ain't balanced
Well Bundy its been 3 months does it still work? I'm leaning towards no...
I’m leaning towards yes!
@@bundysgarageI surely want to kick this method of repair because it can't possibly be good for crank wear but then again i have a 98 Acura RL and spending 300$ for a new harmonic balancer doesn't sound like something i want to do. I might actually give this a shot. Mine is still intact its just starting to slip the rubber.
@@swilson9794 What do you mean 'slip the rubber'? Belts coming off? I thought I might give this a try. Nothing to lose.
There is an inner steel disc and an outer steel disc, making up the crankshaft pulley. In between the 2 pieces of steel is a rubber joint that begins to degrade over time. Once the rubber is fully shot the outer ring will slip across the inner ring. So he is saying his in only starting to fail.
@@bundysgarage Yeah exactly and in my case the outer pulley is slipping towards the engine. Enough that its causing the power steering belt to bind against the outer pulley on the balancer and will shred itself along with a nice loud whine. And 2 months later i still havent fixed it.
I did not just see a harmonic balancer get put back with JB weld 🙃
Your eyes don’t deceive you, you did!
They make specilized rubber that runs about 300 a gallon for that. You shoould send it to a pro rebuilder.
How mush would you charge me to fix it?
I tried this and it didn't work in the least. perhaps its just the make and model of my vehicle, but this really turned out to be a waste of time and money, so I recommend just replacing the part entirely.
And what do you do if the part is no longer available?
Hey kids! Today we get to learn how to wreck a crankshaft , rod bearings, watch a serpentine belt go up in smoke or many other quick and exciting mechanical failures! And this being used car sales class , it's all good ! Just make sure you give them a 30 warranty at best . You know that the plastic serves a pretty important function right ? Like keeping the engine from detonating NASCAR style when you turn the a.c. on at highway speed . Or starting . Or keeping the belt from shredding, etc.
You sure know how to blow things out of proportion. Car is running fine and the crank pulley is happy as a clam. So chill dude! It’s not the end of the world.
@@bundysgarage It's a joke . I was under the impression that would be obvious sarcasm. I'll try to simplify things in the future . :- /
@@bundysgarage good job staying level headed in response to the haters. You keep doing you. I love hearing creative solutions. JB Weld ftw!
If you don't like it, don't eat it!
Bro
This triggered so many people. Ha ha
My question is if you use job weld to solidly bond the outer ring onto the inner hub of the balancer , how does it balance , it has rubber in between for a reason , if it didn’t need the rubber it would come from factory with a solid pulley to start with. That motor will not hold up very long like that and if it does it will vibrate very noticeably .

Your really funny bro
You’ll never have it balanced again after jb
weld
It does not matter if it's not balanced. Its small enough not to make a difference. Now if it was a high performance 700HP engine, that would be a different story. Plus I saw the car a few weeks ago and it's still holding up strong.
@@bundysgarage good info bro
Do not do this, the rubber isolating ring is there to absorb vibration. Buy a new one or let a shop replace the rubber ring.
Why shouldn’t you do this? It’s not a Bugatti engine? Vibrations are no minimal it won’t even make a difference. Read the rest of the comments down below.
@@bundysgarage we agree to disagree. The rubber ring is engineered there for a good reason. If you are doing this on your stuff fine, but to recommend such a repair and have it let go at 5500 or more - not worth it. New ones can be had (depending on your motor) for as little as $50. Why risk it?
I would not put that shit on my skin broski!
It's not going to do anything to my skin.
You have just ruined the whole point of a harmonic balancer. Glue it or weld it and the elasticity that absorbs harmonics is gone. Hence "Harmonic balancer".
won;t work
JB WELD HAS BEEN VERY DISAPPOINTING FOR ME , TERRIBLE FOR METAL GLASS OR PLASTIC SIMPLY DOES NOT WORK
Are you sure your mixing it right?
One thig a person has to remember is the surface area needs roughed up. With glass that would be difficult but not impossible. JB is just Expoxy.
So unsafe man.
Why is this “unsafe”?
@@bundysgarage
I almost did the epoxy thing after watching this video, but had some second thoughts.
Engine vibrations already broke apart the rubber that the Manufacturer formulated to hold that thing together. Epoxying the ring back on doesn't take into consideration any of the stresses that assembly will be subjected to. Sure it may work for a while, but when it breaks off again, flinging that ring around the engine bay would cause damage like Xena Warrior Princess.
@@anochieugochuku7176 agreed
Where in the F does a Civic Harmonic Balancer cost $100? I just put one on a Civic I'm flapping and it was only $41 for a quality one. I could have bought one for as low as $25... And I don't think I even seen one the was over $70. Go ahead and do this BS fix if you want to be constantly worrying about when it is going to fail. And it will.
You did not fix it. You put 2 broken pieces together. If you outer ring is in the wrong position even 10set you can see a 20gm cm out of balance. If it is off 180set it could be as high as 100gm cm out of balance. By putting it back together with in weld you will introduce radial run out which is bad for balance, belts, and idler pulleys. If it broke the rubber is shot and you are not getting any torsion vibration damping which reduces crack life. Since your car was $100 I guess you don't care, but a damper failure should be repaired by putting on a new damper. If you cannot afford it you shouldn't drive a car.
For real?! What a cheapskate repair. Thing comes loose could cost you the entire engine if the belt gets tangled on the inside of the pulley. Or, the vibrations become so bad due to imbalance, that everything gets rattled to bits..

Man everyone on here acts like it’s a flywheel on a large ocean cargo tanker. That has to be balanced like some Swiss watch time piece. I’m trying to show people how to save money, not spend $45 or $100 or $200 just to get an old vehicle back on the road.
@@bundysgarage He is right though its not the right way to fix the prblem and can cause damage to the engine even in a small car. its a good fix for a short time if you cant get one and need to use your car but, not a good long term fix.
18,000 miles since this fix and it’s still going strong and no internal engine damage. I think it will be ok.
Terrible repair.
Well it’s still holding up so I don’t know how terrible it is? And for all the people saying it’s going to destroy the bearings it’s not a large high horse power engine, it’s not going to do any damage.

Your car.
You should have pressed fit in new rubber and glue!
You can buy rubber on Amazon.
If your going to take a chance, with shobby/diy repair; you may as well do it properly.
I think a home made silicone bushing would have been nice, but alas you say it works, so
good job.
Holy shit this is not how to fix it
