Do i need a new flywheel (replacing clutch)?

[Alpinweiße30]

well i think i need a new slave cylinder, so i towed the car home (like an hr from base to where i live and close to 50 miles) and its in the parking lot until i get some time to install the part. I won'r even have time until the end of oct. oh well.

nice. do the proper break in with your clutch and enjoy. I had to buy a new flywheel when I did my clutch because it was past the minimum thickness. It was part of the reason the clutch wasn't grabbing as well as it should have.

Pic update





Crappy puller i got from Advanced Auto. I had to file it down just so it would grab onto the bearing. Still got full price when i returned it, the guy never looked at it.












Yes, i need new transmission mounts...


All back in


also took off the manifolds and sandblasted them and painted them.

ok, so i got most of it back together. need to put the drive shaft back in and the exhaust back on. We let the lift down and i jumped in to see if the shifter worked and pressed the clutch and it was on the floor, so i puled it back with my foot and pressed again and it was hard. Does the system have to be bled? also after putting all of the shifter and linkage in i tried to shift it and it seemed to be a little off. like i tried to put it in reverse and i didn't seem to have enough room to push it all the way to the left and then up... any suggestions?

If you can't find it after this, I suggest giving up.

I understand that and agree, my point is i do not see this magnet on the flywheel do you see it in the pics? am i looking in the wrong spot?

It will be on the flat surface on the edge of the FW next to the starter ring gear thingy. It looks like a little square piece of metal welded on. It will pass real close to the sensors so it will be in line with those.

no, without the magnet the sensors have nothing to read and the car wont run

i do have those sensors....I do not see a magnet???? it appears the clutch ( at least) has been replaced. is there a chance someone else replaced the flywheel without a magnet?

[lateracer]

I assumed you had a motronic 1.0 like i did. Does your car have the two sensors that plug in to the side of the transmission near the slave cylinder?

If yes, then there will be a little magnet along the side of the flywheel.

If no transmission sensors, then nevermind. It's a problem you don't have.

[Alpinweiße30]

Because there was a debate about the flywheel and what it might look like. THIS is what it looks like.













I am going to go with the sand paper method because i think it looks pretty good.

by the way i do not see this magnet you speak of, and the clutch wasn't "bad" the rear main seal is bad and it was leaking and getting oil onto the clutch which was making it slip.

i had my dual-mass resurfaced. it cost me like $30 and took them half an hour. just sayin'

Do you have a picture of where this sensor needs to be welded? I have a welder so i can do it. Unless this is obvious when i take it all apart a picture would help.

I tried taking a picture of it when I did it, but it just didn't come out well (hood off, daylight shining down, camera pointing up at the bottom of the flywheel...all shadows). This illustration probably explains it a little better anyway.


The yellow is the flywheel, the black square is the reference indicator magnet. The little magnet is a square peg that is pressed into a square hole. It's the only square looking thing you'll see along the side of the flywheel. The red stuff represents what my tack-welds look like.

Literally a 30 second job. I'm pretty sure you can do this without pulling the trans (I pulled mine during this work to do a clutch, so I'm not 100% sure). If you pull the bottom flywheel cover and bump the motor, you'll see it come around at some point.

So, save your money and time-just use some sandpaper on the old flywheel and you should be fine.

x2 - on sand paper surface prep. I did that with minimal break in on my eta and then threw it on the track for two long days of abuse.

When the twin mass assembly starts to go South, it will make a kind of clunking/shuddering noise when the motor gets turned off that sounds very similar to run on (aka dieseling). You'll definitely notice it as it will be the last noise the motor makes when it's turned off. It will do that for quite a while before actually failing.

Upgrading to a 1.3 system isn't a bad idea, especially if you've got long term plans for the car. Swapping to a newer motor will be a lot easier if you've already got that in place. If you do decide to stay with the flywheel reference sensor system, be sure to tack weld the little magnet in place while the flywheel is out. It can pop out, and when it does, there's no quick fix.
