Resolved What is this piece?

[pepsi21463]

I was just cruising down the highway going 55mph when i hear this loud crunching. I'm thinking to myself, what the heck is that??? I start to pull off and i downshift and my clutch feels very...not good . and the crunching continues. I got off the highway and pulled over and the crunching noise continued, but got louder. I get out of the car and check it out, all looks good. i'm confused....

I get back in the car, turn it on and it smelt like burnt waffles and syrup. it was GROSS. i start moving and i shift from 1st to 2nd and hear a loud CLINK, at the same time I felt something in the clutch peddle break, well...this huge chunk of god knows what flys out from under my car. its this big round metal thing, a little bigger than my palm. My clutch instantly burns up and smells like complete ass. I call up my tuner and asked him what it could be, he was stumped. So I really have no idea what this is, and I have shown it to people who have worked on cars for most of their lives and even they are stumped, can somebody help me?

This metal peice is, "was", covered with rubber, but now the rubber is shredded up pretty bad. It's also heavy for its size, it weighs about 1lb.

Wow. I want to put blame on the harmonic balancer, but I can't see how the rim could possibly get so effed without causing serious havoc, and there's no sign of any drive belt grooves on that thing (good pictures, I just wish they'd have helped more). It almost looks like it'd been flame-cut at some point.
I can't think of what else is on a car like that and could still find its way clear to fall off.
Sorry, but I'm Frank Lee Baffled.
Clutch or transmission parts are internal, and wheel parts have axles and the like going through them that'd keep a piece like that captive. Accessory drives have grooves on the outside edge.
Dammit, I don't know.

its does look to be the crank pulley , mine wobbled off when I was doing 75 on I70 and wham wham pop ....belts snapped car lost power and I slid ( snow ) to an off ramp in to the grass.

look there .

Honest to God. I cannot think of anything that looks like that. If it came from inside your transmission it shouldn't be hard to find. Great gaping hole However, I've been inside manual transmissions, and I've never seen it there either. What is the possibility you ran over it, got it hung up in the belts and it flipped out? I'm like Defiant, the only place even remotely close is the harmonic balancer and it's too small in diameter for that.

I would like to know what it is when you truly find out though.

Good Luck

 

[pepsi21463]

Well, I think you may just be right. I will check once I get home. Heres my next question, how would that peice have fallen off like that?

Edit: My car still has power and can still move with no problem, just makes metal on metal grinding noise every 10 seconds. I didnt drive around the block I just had to drive the car into my garage after it got off the flatbed and it made that noise, and the clutch smelt horrible the whole time. Could it still be that pulley? If it was, I really hope I didn't screw something major up moving it

Well I watch the road VERY closely. About a month ago, there was something in the road and I wasnt paying attention and I ran over it, turned out to be a peice of underwear and it got stuck on my driveshaft. But this peice is too small for my car to pick up.

I felt this peice break off as I shifted, I felt the vibrations of it through the clutch peddle. The second that thing fell off my clutch burned up ASAP. The car is going into the shop probably Tuesday so I will keep you updated. Probably something simple that we can't think of

Are you sure it's your clutch that smells? Check other areas with moving parts- belts, fans, etc.

Check your timing belt before starting the car again and make sure you are in time and the belt is in good condition.

I checked the belts, everything looked good. I will take some detailed pictures once I get home. That peice smells like a burning clutch. I have been driving manuals for a while and I'm fairly confident that the smell is a burning clutch, but thanks for the advice I'll definately check out surrounding areas and I'll get a better look at stuff tonight.

Definately let us know. I would love to know where it came from too. Of all the cars I have worked on, I cannot of the life of me tell you what it is.

[pepsi21463]

Could it have been a part of my bell housing? Possibly a peice that WAS apart of something else, just broke off? There are 2 "divets" on one side, but they don't look significant enough to hold it in place to something.

 

[4g63t]

Could it be the top section to your through out baring? Just an idea,
Also take a peek at your clutch through ware the fork goes in the tranny you might be able to see whats going on.

 

[punishercb]

From that picture, it really looks like a thick piece of pipe cut with a oxy-acetylene torch. But the question is, why was it in your engine bay?? And why did it f up your car?

 

[pepsi21463]

So I will be jacking up my car soon and I will take plenty of pictures, I'm definately not a DSM or transmission expert so I will need your help, thanks a lot guys

Anything I should look out for? Specific places I should look?

About a 100 miles more south and I would be able to help. Not recognizing the part I would have no idea where it came from without looking the car over. Where exactly did it fall from. when you picked it up from under the car where was it located. If you can figure that out it could be very helpful and ring some bells.

The part fell from under my car as I was moving, so it's hard to tell where exactly the peice came from. I heard it fall, and felt it break through the clutch peddle. The piece then popped out into the middle the street (kind of down the double yellow line) then rolled about 15 feet before it fell, and I immediately pulled over and walked back to pick it up. I really don't know where it fell from besides that I could feel that, or something close to it, break at the same time.

 

[wolf20043]

The best I can do at the moment. I have a tranny and a couple of shortblocks in the shop, and I am going to go out in a few and see if I can figure where something as big as a CD and metal came from and we can go from there. The tranny is already mostly apart so it should not be a big deal. First things I would check for is holes or breaks in the tranny casing to see if that would be where it came from. Problem being that most everything for the tranny is internal, so for it to have come from there you should be able to see where it could have come out. I will let you know , Bro. Also check the clutch line at the bottom of the tranny and see if maybe it was something that kicked up from the road and possibly took out the line.

[pepsi21463]

Ok, well we're checking out the car now. Looks like some parts that are suppose to have belts...dont. I dont know the name of this peice let me look around I'll tell you, I'm short on time since I have to leave for work soon but I took some pictures (best I could since this part is hidden).

http://members.shaw.ca/dsm.1000q/Engineprimer/2G/Q2.htm

its in that section of the block, in the rear right hand side at the bottom, not connected to the block (I dont think). Let me jack the car up and I'll post again.

 

[pepsi21463]

Well my dad is an ass and thinks nothing of it, a belt is GONE. I dont know what peice, he said its something that eventually connects to the crank....now I'm having nightmares. any idea???

 

[weith1111]

I can't imagine that is anywhere off of a DSM, but if it is, it could be some mangled version of the crank pulley as mentioned before. Get some pics of the belts and pumps, and most of all the crank pulley.

will do, now im wondering if that peice did come up into my car somehow. I will post pics once I get home.

 

[19Eclipse90]

The only metal parts that have a belt and connect to the crank are the balance shaft, cams, harmonic balancer, crank pulley, water pump pulley, the pulley for the alternator, power steering pump, A/C compressor, and the miscellaneous idler pulleys which can be ruled out because they are too small. What I don't understand is how any of these will mess up your clutch unless they fly up to smash the master cylinder. The chances of this happening are very low because to do this the pulley would have to fly off, take a very straight shot, hit, and then to just fall out of the bottom of the car as easily as it did doesn't make sense.
Puzzled with the rest.... keep us posted.

get a new crank pulley and get ober it.. see your crank pulley separated, the rubber piece on the inside fell out,, the outer ring is just chilling on there, the squaling ius your AC belt getting tangled up,

it smellt so burnt because your belts rubbed aginst the timing cover, and your pulley rubbed againt the splash guard...

mine went kaboom at 24000 miles.. 4g63 beauty right there

i put the car on the lift, and you couldnt even tell that the crank pulley was busted, it justt threw the belts, when i tighten the belts, i noticed the crankpulley started to separate...

 

[Mike Marnik]

ya i would say it looks like the center section of the crank pulley. its also the same size as the a/c compressor pulley but it doesnt have anything on it like that.

Had to read to make sure no one siad it first. ^^^^^^^^the belt that is missing is the A/C belt. Take a look at the A/C and see if the outside ring of the pulley is still there? Best I can think.
