Googling for that problem would probably give you faster results.
Don't forget the valve lash adj if it hasn't been done in the last 50k miles.
If you had mechanics do the work, what do they think?

The mechanic I took it to replaced all of the things above. The timing belt was fine, but the last change was not done with the components. I am currently taking the car back on monday to have it looked at. Could it be that bearings at some other place are going bad as well considering a whirling noise and wobble are still being produced?

P.S. my Cr-v has 184,000 on it currently.

 

I am surprised that the mechanic replaced the timing belt components and didn't replace the timing belt since the labor difference would have been minimal. Hard to judge how 'good' the timing belt is just by looking at it.
Getting along with your original question, I do seem to recall others having problems with a wobbling crankshaft pulley.
Do a search in these forums and also online for the quickest results and likely important info.

PS: Don't forget that very important valve lash check/adj.

 

Was the harmonic balancer AND crankshaft pulley changed as a unit and yet the pulley still wobbles? As far as I know, the thing is a 3-piece integral unit and cannot be disassembled to change just the harmonic balancer. Maybe crankshaft bolt is not tight enough?

 

How bad of a wobble is it?

 

Change it! If it vibrates hard enough it will vibrate the bolt loose, break the keyway and can possible break the the keyway groove out at the end of the shaft. Had this happen to my Crv, forgot about it till i seen this post.... If i recall right its 2 pieces held together by a rubber center to absorb vibration.it gets hard or brittle and starts to wobble and vibrate

 

From my personal experience on this subject, there is no crank pulley assembly like a new OEM one. There is rubber that dampens vibrations from the motor between layers on this unit. I've never once heard of rebuilding one, and the guys I hang with rebuild everything.

Usually you just try to buy a good condition, used pulley. Because a new one from Honda will run you about $500. There is always aftermarket stuff, but be wary of the cheaper stuff.

 

I would just go to the junk yard and find an old Honda and get the pulley. But they sell the pulley with the engine. You will need to find one with a busted engine.

 

Online Honda dealer parts sources have a new balance/pulley for $163. For the price, I would go new, you would not have to find a salvage yard who will sell the piece separate, not know the condition of the used piece, and possibly having to remove it yourself.

 

The wobble can range from minimal to moderately bad. I got back from the shop and they suggested that the "new" harmonic balancer might have just been bad (they couldn't have just installed it wrong, of course). Since it was on warranty, I get another new one installed for free.

But there is still an possibly unrelated noise! Sounds somewhat deep, almost like a bad bearing type sound. The mechanic said he has never heard anything like it.

 

I dont think that they could have installed it wrong, it only goes on one way. Unless they cross threaded your crank bolt...

At any rate, bottom end noises are bad news. Prepare yourself for an engine replacement, if that truly is the case.

 

Almost sounds like a broken crank to me.

 

I sure hope not. I'm taking it to a good friend who has a transmission shop to look at it today. The noise is just so hard to pinpoint.

 

Might be worth your time to drop all the belts, and give it a crank. See if it still makes the sound.

Then even worse, take off your timing belt, then the cams and spark plugs, pull the fuel pump fuse, and just let it spin, see if you can confirm if it is the bottom end at all.

Might be a better way to check it but that's all I've got.

Edit: Just thought about performing a run-out check on the crank, if your pulley is not the culprit of the wobble.

 

I am not sure how an engine could continue to run with a broken crankshaft.
A short video would have helped, I am going to guess the balancer movement is axial, moving towards the block and away, instead of a lateral wobble.
Is your CRV a manual transmission? With the internal noise and pulley movement, I will guess the thrust bearing is shot.

 

My crv is actually an automatic. And I have dropped the belts, still makes the noise. Along with just repairing things in due time I replaced the timing belt, water pump, harmonic balancer, and belts to make sure it wasn't any of those components making this noise.

So I've gone through somewhat of a trial and error approach to this and still have not found the answer.

 

Can you access it enough that you could use a pry bar and see if the hub/crank assembly has any movement in and out?

 

Just got back from the mechanic. The harmonic balancer was replaced again and the wobble is worse than before. Needless to say I'm never going to that auto shop again. It's not looking good right now.

And no, I could not wiggle the pulley when the engine is off.

 

I wonder if the tech is reusing a crushed, crush washer or something silly...

 

I don't believe it's a crushed washer. In fact, I was told that it was simply just an optical illusion. Not really sure how that makes sense.

Either way I ended up getting my idler pulley replaced which attributed to much of the noise. But I am not almost sure that the remaining wobbly noise is coming from the AC compressor. Any thoughts?

 

Take the belts off.

 

Still makes the noise.
