  • The purpose of an harmonic balancer is to absorb crankshaft vibrations. Harmonic balancers are typically constructed in three pieces. The first piece is often called a hub. It bolts to directly to the crankshaft. The hub is surrounded by rubber or fluid which dampens crankshaft vibrations. The outside layer is metal which has grooves on it for the belt. Over time the rubber and/or fluid layer deteriorate causing the outer pulley to shift forward. This causes belt miss alignment and can ultimately result in crankshaft failure. When the harmonic balancer is broken, it must be replaced. ATP Harmonic Balancers fit and function just like the original part restoring the engine to normal operation.

Harmonic balancer question

Showing 2 out of 10 Posts | Show 8 Hidden Posts
Question From moparsrule60 on Harmonic balancer question

Need to install the harmonic balancer on my 1995 dodge neon. Cannot find an installer tool to fit in my area. Guy on youtube got a longer bolt than the original one put a couple washers on it and the used it put the balancer back on. My problem is everywhere I looked nobody has the size bolt I need . Fastenal is closed but will be open on monday. Was wondering if I could slowly tap it on with a hammer and just use the original bolt to tighten it down the rest of the way.

Response From speed





that is what happens when you use a hammer to install your harmonic balancer

Response From Discretesignals

Where is the rest of it? Can't you JB weld that?

Response From speed

The rest is elsewhere it was in an ls1 for a 02 camaro for a graduate from years before

Response From nickwarner Top Rated Answer

Gee, I bet we could get a piece from a Geo Tracker that would work fine.

Response From Tom Greenleaf

If I laugh any harder there could be poop in my pants!

Response From Hammer Time

That's why they make installer tools. Using a bolt is not a good idea. It can pull the threads out easily.

Response From Discretesignals

wondering if I could slowly tap it on with a hammer and just use the original bolt to tighten it down the rest of the way.



See this main crankshaft bearing here? It is built to control the thrust (back and forth) play in the crankshaft. You bang on the balancer with a hammer and you end up damaging the thrust bearing. Then you end up with big problems with the crankshaft walking around.

Response From re-tired

I agree ..NO hammer. However there may be hope . Hit the phone book in the morning. Some parts houses rent tools and you may get lucky.

Response From speed

i have pictures of what happens to a crankshaft when you use a hammer to install a harmonic balancer, will post them when i figure out how lol

Vibration in Geo prizm

Showing 3 out of 12 Posts | Show 9 Hidden Posts
Question From chadjordan93 on Vibration in Geo prizm

Year of vehicle-1994
Make of vehicle (Chevrolet/Geo)
Model of vehicle (Prizm )
Engine size (2.0)
Mileage/Kilometers-207,000

Need help trying to figure out a problem. I did some research and they all say tires or broken engine mount but neither is the cause for the vibration at idle and high speeds. My car vibrates when im idling or going over 65, just put new tires on and Ive had the engine mount checked, the oil has always been changed when time and there is no exhaust or body damage that is known. So if any one has solved or had this problem and could lend a word that would be great
Thanks,

Response From Mr.scotty

So it shakes when the vehicle is in park or in gear sitting still?
If it only did it while moving or just sitting still it probably would be easier to figure out.
Did it do it before the new tires?

Response From chadjordan93

it shakes when its in park, neutral, and at any speeds really, but the higher in speed you get the worst it gets.
its done it since ive had it, before and after new tires.
no wrecks before and im only the 4th owner

Response From Mr.scotty

And all the mounts are good?
Transmission,engine, and suspension?
Are you sure the car just doesn't have a miss fire?
No check engine light rite?

Response From chadjordan93

And all the mounts are good? yes
Transmission,engine, and suspension? yes, yes and im sure since they didnt say they were bad when i got new tires, i asked them to check out that stuff
Are you sure the car just doesn't have a miss fire? pretty sure it doesn't, because if it did the vibration wouldn't be this consistent( from what i know, which isnt alot)
No check engine light rite?no lights on at all, this is the best running car for its age ive seen just the vibration

Response From Mr.scotty

only other thing I can think of off of my head rite now is the harmonic balancer pulley.
If this is bent or something it could cause the car to shake when moving or not moving.
If that is whats wrong with it, it can make alot of big problems. have it checked out rite away.

Response From Tom Greenleaf Top Rated Answer

That's a lot of miles on this pup. I'm with Mr. Scotty to check the harmonic balancer and other belt driven items. If no check engine light and might not maybe a cylinder balance and compression check is in order now if other things check out.

In that it can do this sitting still wheels and suspension item really can't be the cause. There are more than one mount to engine/trans to verify good. Sometimes exhaust may cause issues too with a big word - a resonance frequency from bad parts/hanger making the system whip around. My own car has balancers (counter weights) on exhaust to control that! Gotta check all of it IMO,

T

Response From Mr.scotty

Yeah.., At this point it would be anything that rotate when the engine is running or a mount.
Like you said theres no way it's a suspension bushing or mount.

The exhaust hangers are a good point.

Response From Tom Greenleaf

Mr. Scotty - anyone: Ever see that brand new bridge (forget where) that just went nuts (pics of it with cars on it then total collapse) as there was no control of vibrations which any engine takes into consideration too. If exhaust can wobble around just so it's possible it gets to shaking. It's not the highest thing on the list but something to rule out IMO,

T

(edit) Found the YouTube of that bridge and what can happen with resonance if not controlled - was 1940 - the Tacoma bridge.

Should show (short version) from this..............

Response From Mr.scotty

I know hard to believe it huh..

Response From speed

in my opinion id take it to an actual shop, not a tire place to get the mounts checked out. i work in the express lube, we do "visual" check on components but its not an actual check, i would not expect a person changing the tires to catch a faulty motor mount.

Response From zmame

could be a number of things
tune up
timing
vacume leak
motor mounts
or a combination of these things

92 Geo Prizm vibrates rough at 1200-1800 Rpms

Question From Big-T on 92 Geo Prizm vibrates rough at 1200-1800 Rpms

Hello all my name is Tony...I am good with my hands but def not a motor head...I can do lots of things on my own when i find the problem that needs to be fixed.I am here today cause i can not even find the problem to fix it, And would like a large range of knowledge to try and steer me in the right direction,Ok i am tring to fix my girl friends car...It's a 1992 Geo Prizm Lsi with 195,000 miles and a 4 cyl 16 valve Fe motor in it(After research its same as a Toyota Corolla)..I am not the driver of this car so i can only go off what she has told me...I know the car ran ok for it's year and miles...But out of no where she has this bad engine vibration that is very bad...I went to the easy things first which were indeed busted to pcs(Engine mounts and trans mounts)..Did not fix the problem..This problem does not require the car to be moving to do this so i scratched off tires/Drive line(Axles)..This accures at somewhere in the range of 1200-1800 rpms,At idle it's fine...and at a higher rpm it's fine....I have pull trans and dropped oil pan and i still do not see nothing that would cause this..I was told a bent piston rod could do this(From A LOCAL SHOP)..But i put all cyl at top dead center and stuck gauge through spark plug hole and not even a slight diffrence(I figured that was enough to take that off the list)..I was wondering if a bad torq conveter could cause this prob..I also notice when i dropped trans it was marked with yellow marker 97 corolla as well as the torq converter(So i know it's either used or a junk yard item)...But it was the one in there since she owed it....Plus i was also told to remove all belts and try to wiggle all pully's up down and back and forth(Still nothing)..I was told the main pulley is a balancer norm made with rubber in it which i could see,But no noteable damage....If anyone has heard of this or could give me simple things to try i would love to soak in the info and give it a shot...Also while the car is running and in park could something inside trans cause this...?.....Thanks for your time and i will be checking back daily....She has my car and i want it back(Smile)...

Response From dmac0923

you seemed to have covered the basics pretty well.

my recommendations would have been

motor mounts
trans mount
axles
transmission input bearing

you may be onto something with the harmonic balancer. I have heard of harmonic balancers 'shifting" meaning the rubber and the metal are no longer one piece and is taking the motor rotating assembly out of balance ever so slightly

Response From Big-T

Well yes as i stated i am good with my hands and try alot before i ask questions.I am a suspension mech for cars and rigs just not a daily motor guy....Again i have trans out and oil Pan down as of today and am lost on whats the issue here ...Trans has leaks so i wanted to seal it anyhow so i figured i could look to see if the prob was there somewhere and while it's down and out i will do rear main seal...The problem here is many things can be done while i have it apart but i hate to do all this and find out that i can't solve the problem i am here asking about just to turn around and junk the car....Grrrrr

Response From Big-T

Ok...Does anyone know if this car that i posted about in first post have a balanced cam in it (16 valve Dohc Fe model Motor)

Response From DanD Top Rated Answer

I had a look through the service bulletins that I have and found nothing directly concerning engine or trans vibrations. There was one article on the torque converter’s clutch coming apart causing a shudder but I’m not sure if this would address your concerns?
If you don’t physically find anything, put the car back together and try starting the engine with the torque converter left undone, from the engine. If your vibration is gone, you’ll know what you’ll be doing again; it always comes apart easier the second time. LOL
Sorry I don’t mean to make fun of but that’s the joy of searching for something that doesn’t want to give up its secrets.
I don’t think this engine uses an internal balance shaft?
When you checked the harmonic balancer did you try running the engine with the belts off? I’ve had water pumps or AC clutches not make a sound but the bearings be all but destroyed?

Dan.

Response From Big-T

Well no worries about poking fun,I have torn stuff apart many times just to find the problem and your right second time is always easier..(Smiles)...So back to the topic,I spoke with a local trans guy that has been in bizz for many years here local and explained the issues.. And thats who said he was not sure of this motor But has heard of the balance cam chain or something to that matter would get wacked and cause a shake/Vibration...He also noted to me about unbolting torq converter as well as you noted start motor and see if i still had it(I didn't know i could do that duh!!) So i am going to reseal the whole trans and rear main seal and throw it in and see what i have....I also was told by the trans guy that the main pulley may not wobble, And by hand could not tell if the rubber was bad but it could spin inside itself to throw it out of balance,So...1st i would like to thank you for looking that up for me cause i neither couldn't find anything about a balance cam for this car.....And thanks for your thought about the other pulleys,But if you was here you would know for a fact it was not no water pump pulley(lol)...This is a crazy vibration...But be sure i will check them all before i put belts back on,Also i checked the main pulley while belts were off(No tension)....I will do what i stated and keep yah posted on progress and or help if i need more...Thank's Tony...Any advice while i am getting to this i will soak in to my thoughts....

Response From Loren Champlain Sr

Tony; If you haven't reinstalled the trans already, check the flex plate very carefully for cracks. Between the torque converter, flex plate, and harmonic balancer, sounds like you are on the right track. And, with your attitude, I'm pretty comfortable in saying that you'll succeed in finding the problem. Good luck.

Response From Big-T

Well i am on hold do to going to my girls this weekend,But i will be back at it after the weekend and need to get it out of my shop where i work...(Kinda taking up a bay from my boss(Not Good lol)...When you say flexplate do you me Flywheel..?...again not a motor head so words and terms my get me by surprise...Thank you all once again...Tony

Response From Big-T

Ok my online friends/Helpers...I had time to return to this project and here is my results....

If you rem i had removed trans to get a further look.....Well trans turned out ok.....Flywheel was ok.....so i resealed rear of motor and reseal the whole trans/and new filter...I put it together enough to start it with out torq converter connected........(No vibration)....Then i bolted torq verter back up....(Still no vibration)......So i installled all the belts and replace a cv boot ..Lowered the car and took for a drive and still ..(No vibration)....So i ask myself...What and where did the vibration go....And what caused it....Am i happy it's gone...Yes....Am i bothered i didn't do crap that should have fixed it, Of course.....I would have like to knowN what fixed this issue....Grrr....I didn't even get to change the main crank pulley ,Vibration was gone before i got that far......Hummmm i am puzzled... Tony
