Hi all I have another post going about me removing my oil pump and found the only thing wrong is the O-ring seems to be square and hard and fits into the oil tube loosely. But now after examining the crank that I pulled off the crank to do the oil pump seems to have a seal stuck to it with the timing cover gasket under that. I’ve never seen the timing cover gasket come off with the harmonic balancer. Any input on what happened

On the front between the bolt and harmonic balancer is a washer. On the back is a crankshaft seal i.e. front cover seal.

OK but what is that little seal that I’m showing in the picture that I’m lifting off of the crank. It appears to be three pieces that top piece that I am lifting off something in the middle that’s holding the timing cover seal on.

Also I can’t get the seal off of the crank there is some round looking ring stuck to the harmonic balancer

If I am reading your question right ,
The " thing " on the end is the diamond dust coated friction washer.
It is there to help the non keyed damper not slip be locking it to the oil pump drive.

Why your seal is stuck on the damper and spinning in the cover , dont know .
You need to pry it off , clean and inspect the damper surface.

Exactly so that washer just clips to the end of the harmonic balancer correct and then you press it back in. I didn’t realize that the oil seal is hard as a rock that’s why it wouldn’t come off but after pulling on the path that little bubble section on the cranI didn’t realize that the oil seal is hard as a rock that’s why it wouldn’t come off but after pulling on the path that little bubble section on Harmonic balancer. The balancer does have somewhere on it which I cleaned up with some fine sandpaper. Do you think that we are Little see you at the end would have anything to do with oil pressure

That looks like a mechanical seal. Every water pump has one. I've never seen one used in that location but I don't see why it couldn't be used there. I wish I could see how it all went together.

The way you see it in the picture is the way that the polar pulled it off of the car. I’m hoping that the placement is correct because that’s how I plan on putting it back together.

I'm talking about the entire assembly attached to the balancer. If I'm right about the assembly being a mechanical seal, the "thing" you are talking about is just a part of the assembly. But as I said I'm not familiar with this assembly and I wish I could see it in person. I absolutely could be wrong about it being a mechanical seal. But it sure looks like one in the picture to me.

Though now that I think about it, I do remember a 90's Corvette that used a mechanical seal to seal the crank in the timing cover. But that was an oddball one off at the time.

There definitely is a timing cover seal which you can see on the harmonic balancer in the picture the seal that I’m talking about is that washer with the rubber on it that is stuck on the end of the harmonic balancer. So so long as that is where it supposed to be then I’ll just put it back together in the way that it is of course with a new timing cover seal pressed into the cover and I’ll leave that other ceiling washer at the end of the balancer when I press it back in. And thanks again for all your replies and help

This is too simple,

There is a front cover seal which is stuck on your damper snout.
It is rubber coated on the outside and has a teflon seal lip that contacts the damper .
You need to pry the old one off and discard it.
New seal is installed into the cover.
Its lip is kept dry .
The damper snout is cleaned polished and left dry .
A smear of non hardening sealer is wiped in the bore of the damper.
The diamond grit washer ( I would go new myself ) is hooked on the little retaining groove.
The damper is installed to spec.

Gotchu that’s what I was thinking and how I was going to put it back together just wasn’t sure I’ve never seen that little spacer washer before. Thank you for your replies and input

This is how much smaller the O-ring is you can see the gap all the way around

 

[Danv508]

My guess is that when installed on the pickup tube, it will expand and conform to fill the gaps. I only ever put it on the pickup tube, never into the pump first.

Is that the old ring?

Yes the picture is of the original O-ring

The service manual shows a one piece seal that's pressed into the timing case cover. The crankshaft spins within that stationary seal lip. Yours looks like that seal decided to separate, become a two part seal, and loose its friction fit in the timing cover and maybe become a spinner with the crankshaft.rotation. I agree with "95wagon" on what he says you need to do, except for the washer talked about. I don't see any reference info about a washer (for the LS2) If your engine was an LS3 however, they do show an added "lipped" steel washer that would be installed on the ballancers snout prior to it being pressed back onto the crankshaft. Must be a spacing thing for the crankshaft design on that engine.

I’m just going to put it back together the way that it is I am pretty sure that the dampener is ruined because it looks like the seal cut into it and I’ll just keep my fingers crossed and try to find a dampener in the future in better condition.

Reset. It's a $1500 car. No need to waste money or breath. Use it or not does not matter.

Thanks for your input

 

[Danv508]

Balancer is definitely junk

 

[Danv508]

OK so now I got in the new doorman dampener and it looks perfect but my question is that rust washer with the rubber on it does not snap onto the end cone of the new balancer. Also I did not mark the position on how the balancer came off is that a problem?

 

[Danv508]

Position doesn't matter, is that a new friction washer? If not, may be deformed from prior use and should be replaced.

Thanks for the fast reply what about putting the new harmonic balancer on I know everyone says not to bang on it with a hammer but if I get it somewhat close to the factory bolt be used to pull it back on.

You really should pick up a GM manual for this work as well as using the search feature of this forum.

I know I know but I really didn’t think it was that involves to remove the harmonic balancer and put it back on. Now I need to figure out a way to get it back on the car I don’t think I’m gonna have any choice but to tap it lightly like I’ve done with many cars in the past till it starts to catch unless someone can think of something else. I’m trying to locate a balancer installer tool at maybe AutoZone now but it’s not looking good. Once again thanks for everyone’s input
