  • 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.

Question From cpr on [ Pictures Added ] 1999 Subaru Legacy Harmonic Balancer Woodruff key tightened in wrong position so was never locked?



1999 Subaru Legacy 30 Anniversary Edition Harmonic Balancer failure.

Hello I need help with a situation involving a Harmonic Balancer for a 1999 Subaru Legacy Sedan

About a month ago the head gaskets blew and had to be replaced. Yesterday while driving the power steering stopped and all of the lights on the dash lit up, then the radio died and then the brakes were almost gone but enough to glide to a gas station with a repair shop. Once there the car would no longer start.

The new mechanic after an inspection (originally had said that there was a separated or broken crank shaft) told me that I needed to replace the Harmonic Balancer and that the bolt was not put on correctly. He also said that the last mechanic was responsible since they had to put it on when the head gaskets were replaced.

I called the other mechanic and had them talk to each other. When I called back he told me that what the new mechanic was saying was impossible and that the bolt would have blown right away. Unfortunately the two mechanics are 45 miles apart so he cannot just go and look at the car of easily have it towed over to his shop.

The car was driven a few hundred miles before the failure and I do not know what to believe or if there is some sort of misunderstanding and both parties are correct.

Any help is greatly appreciated.

132,000 miles
All-wheel-drive,
2.5 liter DOHC fuel injected 4 cylinder
16 Valve boxer engine,

Response From cpr

$300 later the car is working fine. Here are some photos of the broken part. Mechanic said it was obvious that it was an installation error and not a part that just decided to break.

Drove about a 1000 miles in between.

Thank you again for all your help.

Response From Sidom

Thx 4 letting us know the outcome....

They say a picture is worth a 1000 words.....

I won't go on & on...... I'll just leave it at

"Wow....There's really not a lot you can say about that....it's pretty obvious"

Response From Tom Greenleaf

Thank You for coming back with what was found and now I tend to agree. I'm still surprised it made it very far at all. Great that this could be fixed for just $300 -- I was real worried about that causing a real nightmare.

I'll see if just one pic will direct post for archives,

Thanks,

Response From cpr

The mechanic is saying that the Woodruff key was tightened in the wrong position and was never locked. He said it was clear that it was a result from being put back on and was obvious when looked at.

The previous mechanic says that if it was done incorrectly that it is a very long bolt and that it would have came undone right away and not after being driven for a month but is willing to look at the old part to determine if they are at fault.

Thanks for all of your input it is greatly appreciated.

Response From Sidom

Well that's a good sign he is willing to look at it. Most shops if they caused the problem will step up and take care of it.
If it was a defective part or a bolt that broke then you can't really hang that on the shop.

This is where it's better to let the tech who can "see it" make the call........ I'm not sure what he meant by the "keyway (woodruff) installed in the wrong position", there is only one position for it. Even if he put the key in backwards (some can be installed backwards, others have no frt or back), he would've had trouble getting the balancer on, but once it was on, if the keyway didn't fall out it would've held....


The bottomline for me would be, either show me a defective part or explain to me a very convincing theory on how a part that was removed & installed came off in such a short amount of time......

Just a quick look from the shop owners side. He has to judge what type of customer he is dealing with. We won't even go into the bad ones because this isn't the case here (but he has to deal with those as well). Sometimes when work is performed on cars, other areas fail thur no fault of the tech (sometimes right there in the shop). The customers stand point is, the car was fine, I never had this problem before until you worked on it. Normally it can be logically explained and shown that it was just something else that fail but it usually never goes over well and more times than not, the dishonest mechanic card is played. That is probably where he is at right now, trying to figure out "what happened?" Was there a defective part? Did something break? Has someone else worked on this car since?

If it's obvious one way or the other, he will probably do the right thing....

My lastest......An 05 F150 came in for a diag & lof AND window diag..... The lady stopped at B/K for coffee on the way to the shop & regulator cable broke while she was in the drive thru and the window fell into the door. The SA & I argured for 10 minutes about who the lucky one was....My theory was he was the lucky one....that cable would've broke on me if she hadn't of stopped & he would've got his azz chewed out bigtime..... His theory was, I was lucky because I would've been doing the motor & regulator for free...... at the end we agreed we were both lucky.......Not lucky she had a problem, lucky her problem didn't happen in our care.........

Response From Sidom

Wow...A gas station with a repair shop....Now there is a dying breed you just don't see too much of anymore. which is really unfortunate but like anything, a sign of the times we're living in.....(Man I have a ton of great stories.....ok,ok enough nostalgia)

This is a tough situation and the key point is really vague, "the bolt was not put on correctly"

With any repair, when something comes apart or fails in an area that you worked, while it's not a guarantee it's tech error, it's pretty much "guilty until proven innocent". I may not agree with this, it's just the way it is.....

I think in this case it would come down to how the bolt came off. If it simply fell out, that would be a sign it wasn't tightened properly. If the head of the bolt broke off, that would've been a defective part.

I see where the repair is a month old but didn't catch how many miles have been put on the car since then........

Response From cpr

I am not sure exactly how many miles we have driven but I would estimate about four to five hundred. Went on a long drive the day before (187 miles as google flies) with no symptoms.

I realize the key point is kind of vague and hope to learn more tomorrow morning. When I hear all of this talk its like the school teachers in a peanuts cartoon but tomorrow I will write everything down since this is not being easily resolved as I hoped it was going to be.

Thank you for the insight

cpr: What is expected now to repair this? Just a new harmonic balancer and bolt? That and probably belt(s) as they would have tangled up and might have caused some other damage. Some engines would be hopelessly damaged if run without one and rather quickly.

This is going to be a rock and hard place IMO. It already needed head gaskets - WHY? Did you overheat this to cause that? Never say never but I don't know of this engine layout to be prone to blowing head gaskets as much as some.

Harmonic balancer is just as the word implies. It's there to balance out harmonic imbalance natural to an engine. The inside metal that bolts to crankshaft is isolated by rubber to the outside ring and absorbs the resonance. That rubber can fail even though rare to me it's happened. Heat or oil all over it can cause that and the forces of the "resonance" are remarkable and really could undo a properly tightened crank bolt - again IMO.

The question is and will remain a mystery as to whether the bolt wasn't properly tightened or the balancer failed so you'll want to have the balancer to see if it came apart. If it did and may not have, then it's lousy luck and could easily have been missed as defective OR somehow damaged in the course of removing it for the prior work.

In that this lasted a day it probably was properly installed but I can only guess. I'd have to do a research on the specific engine, rotation vs the threads of that bolt to see if the propensity is to loosen or to tighten by the resonant forces. Most engines take that into account OR use thread locking goo OR the item is pressed on as every harmonic balancer I've dealt with is and I haven't dealt with one on any Subaru by chance.

Seriously hard to say what happened or who's to blame. Should a tech have noticed a problem with the balancer? Not sure that would be so easy if it worked at all from the head gasket job. Should it always be replaced at a given interval or if removed - I really don't know on the particular engine but never heard of that.

If you are looking to get this remedied by the shop that did the head gasket work it's going to be tough,

2002 Subaru Forester keeps throwing it's T belt

Question From Barefoot on 2002 Subaru Forester keeps throwing it's T belt

2002 Subaru Forester 2.5L non turbo 88k mil.

After I did a complete rebuild on the engine after the second time it over heat. I throw the timing belt after about 500 mil or about a week.

I did the valves, T belt and T belt kit. and it throw the belt a second time. engine did not over heat and the belt were new. timing was set it starts and run grate.

Please help,
Barefoot

Response From diyautoelectric

Try running it with the timing belt covers you should be able to see where it is walking off or rubbing something

? General if all was done properly is just maybe drive pulley usually the harmonic balancer may have moved out of place and belt isn't in plane with other pulleys?

Response From Barefoot

I have check out the lining up of all the gars the belt rides on. only the tensioner is off just by little. about 2mm from the balancer. does the balancer carry an trust washer?

Response From Tom Greenleaf

OK - this is an involved job if you do it all. Any of the parts if bad could cause a disaster like that as it's an interference engine to boot. Valve damage likely and surprise just another belt it runs worth a damn.

I really don't know how bad these can crash if belt timing is lost with engine running.

Is it running now at all or did it with subsequent new belts?

I really think you need to go back after a compression check and look at every part and detail involved.

Not many Subarus ever came my way for this - just routine work so can't say all the layout off the top of my head. Balancers drive the other belt(s) where you see it. Not sure if that slips out some if it would effect crank gear?

Response From Discretesignals

When you state it is throwing the belt, what exactly do you mean?

Can you take a picture of the front of the engine with the timing cover removed and the new belt installed?

Response From Hammer Time

I wasn't paying attention. I thought he was talking about a serp belt.

Response From Discretesignals

Thank goodness it isn't a DOHC boxer "throwing" the belt.

Response From Barefoot

thanks for all the advices. The belt has bin extensively damage the second time it did it, the belt roped around the balancer and damage the timing cover. one of the things I notice is that the tensioner does have a little in and out play not sure if it is normal. I had to order the parts and it takes about two weeks to get to Belize.

Response From Discretesignals

You should replace the pulleys.
You should also replace the hydraulic tensioner with an OEM part. Maybe the tensioner is bleeding off causing the belt to loosen up.

Response From Hammer Time

No, if the balancer is off, it is broken and has to be replaced. You need to replace whichever pulley is out of line.

85 subaru-water pump pulley

Question From albqscott on 85 subaru-water pump pulley

I have a 85 Subaru wagon. the pulley for i believe the water pump has come loose on my wagon, all the belts were loose and it caused it to over heat and loose power steering, today i pulled all the belts off, tightened the pulley put the belts back on and tried to start it. Started okay but almost immediately i noticed the pulley was loose again. Any idea why it keeps coming loose, is the pulley bad or something internal, not letting it tighten properly? all the help will be appreciated. thanks

lost in albuquerque

Response From Tom Greenleaf

Is the waterpump bad itself? Check the loose pulley for what it mounts to for the problem,

T

Response From albqscott

as far as i know the pump is fine, it may not even be the water pump pulley, not sure no manual, it looked like it bolts into part of the timing belt, i could see part of the timing belt anyway when i pulled the pulley off

Response From Tom Greenleaf

Whatever that pulley mounts to -- an idler or whatever seems like the problem. If it doesn't tighten up there might be some stripped threads, loose bolts or something you should be able to see,

T

Response From albqscott

it does tighten up, until the car is started then it comes loose right away, im thinking its the main pulley not the water pump

Response From Tom Greenleaf Top Rated Answer

Is this pulley the harmonic balancer? That would be the only one that would turn with nothing attached as it is right on the crankshaft. They are rubber isolated unseen and could have failed. I don't know of that as common but sure needs looking into,
