Default Crank pulley wobble?

Has anyone seen it like this before? I'm going to order a lightweight pulley but I wonder is it going to fall apart just getting the pulley off?

That looks very odd. Order the Perrin LCP. When you take off the old pulley make sure there is still the pulley key on the crank shaft.

The curiosity got the best of me I ended up taking it off now and what I see is odd.. the bolt was not backed off but the inside of the pulley was very worn :-/ like it was not fully set on the key or maybe the key got pushed in too far? Maybe someone can tell me how the key should normally look on the crankshaft.

I just ended up cutting the AC belt since it was the fastest and I'm going to replace both belts anyways.








Oh never mind going to need a new key!

I would say that was loose at some point in time. Lightened would be a good upgrade.

Yeah I think the last owner tried to do work on this car (car fell on him) anyways I think it was past stuff, I have to look at my pictures back when I did the head gaskets to see how the key looked back then, I got the part number for it.

Seen it before. Worst one ever- end of the crank worn down to a nub... Good thing you caught it now. Get a new key, a lightweight pulley and a little locktite...

Crap I can't find the pictures I took during the HG work I did I wanted to see what the back side of the crank pulley looked like..

I can say from the little bit of pictures I had left it does seem like the key got a chip knocked off which then I guess the torque could cause the crank pulley to slip on the crankshaft which ended up eating the inside.

I know I'm going to have to clean up the end of the crank sprocket so I'm going to buy another one It's $24 so it's not much, and cleaning up the end of the crankshaft scotchbrite works right?

Also I wanted to know having a lightweight pulley does it help when driving in slow traffic with a 5MT so you don't feel the A/C cutting on and off so much? Sometimes it would kick in just as I would let the clutch out.

Light pulley would make the A/C cycling feel worse, less mass to absorb the power drain, but the ECU does an okay job of adding rpm when a/c is cycled. Don't worry about it, it's one of those things that you can't fix.

Scotchbrite works. You are lucky you caught it before it damaged the crank. Get a new woodruff key as well.

So I think it's pointless and a waste of money to buy a new crank sprocket then as well right? Pulley wont be here until next week or so.

lol but I have another thing to worry about.. I hope it's not headed to SINTON, TX when I head into work in the morning I will have to have it checked out.

Also I swore someone posted a picture of a crank outside of the motor showing the key at the end, I just came back inside after spraying the sprocket with kroil so I can slide it off to me the key looks fine but I'd need to see a new one up close.

Nevertheless the bolt and key I guess will be ready for pickup tomorrow morning from the dealer.

Finally!



I don't know if the dealer forgot about my order or what.. they charged my car and they said the item is most always in stock (bolt & key) but it's been 4 days now.. I guess no rush since it's going to be pouring rain all week.

Pulley is nice but it has no notch for the timing

What are you going to time it to?

I may be doing a bolt on turbo later down the road, gotta think about it first.

Yeah idk why you would need it for timing? It should only line up one way on the key plus the sprocket is what has the timing marks.

The crank pulley that you're holding in you hand has nothing to do with timing.

I think you are thinking I don't know what sets the timing (the ECU does) I'm saying the crank pulley does not have a notch in it.

But anyways I made a mark in the pulley as talked about here.

Oh I see, there's a reference mark on the stock pulley. I don't really see the point, though.

I don't see the point of having marks period on one that's controlled by the ecu I never got around to seeing how torque app matches up with the mark.. I'm guessing it's close enough.

I did have issues last year when my car was pulling timing but it was a cheap fix.

The ecu only controls ignition timing. The crank sprocket/pulley and timing belt have nothing to do with ignition timing. Maybe the reference mark is for crank position indication so you can get the #1 Cyl on TDC without pulling the timing cover or something like that.

I know in the service manual they give some numbers bout what a load would be and what the timing should be.. I forgot I did not look at it too much..

Having said that I haven't heard from the dealer about my key & bolt... I just took some macro pictures.. do you think it's ok to use for the time being?

Had to be from the last owner but when the car ran low of fuel the rocking back and forth and the torque on the key must of smoothed out the whole keyway (How that happened who knows)

but I got as close as I could and it does not seem that bad, at least I caught it early but it's been almost a week and I'm still waiting for the new parts.

Whoa I see what happened.. I went to put the pulley on and wanted to turn it and I felt the whole key move.. I think the key spit or lifted up when I had to put the sprocket back on..

So I still have to wait :-/
