1984special

This is the 12a motor pulled out of a GSL. The flywheel looks ... not so healthy. What's the word on it? Fixable or not? Thanks for the help.

If you need more pics or info, just ask!

PS. The previous owner said it was "resurfaced".

it looks like whoever did the resurfacing also milled off the "ears" (i dont know what else to call them) on the flywheel.... i dunno if that'll affect the balance or anything, but clean it up with a cookie wheel and some sandpaper and see what it looks/feels like, it should be smooth (meaning no gouges or anything) but when you're done... it shouldnt be shiny, it should look a little roughed up.

thats what i'm doing to mine instead of taking it off and paying to have it machined, plus, i wont be having this flywheel much longer anyway, so it dosent really matter.

I agree, the extra maching being done can not be good for proper engine balance.

What is the story behind the engine......

I have a '83-85 stock flywheel that was recently resufaced, let me know if you are intrested. Not sure what the shipping would be, but it damn heavy.

It looks like it has been balanced after it was machined. Just clean the surface rust and use it.

good catch, i didnt notice the balance drillings... yeah just slightly roughen up the friction surface a bit and it'll be fine.

Hi, I'm actually working on this car with '84special, and a friend of mine said something about "heat spots" on the flywheel compromising its ability to interface well with the clutch. So now I'm wondering if he's just a little paranoid or something. Has anyone here ever heard of anything like that and how it might affect performance?

Also, the car had been driven by the previous owner prior to demolishing the poor engine so would we still need to rough up the flywheel? I'm thinking it probably wouldn't hurt, but I just want to make sure. And what grit sandpaper should we be using? I'm typically pretty bad at judging the effects of different sandpaper. Thanks for all the help.

Heat spots are supposedly spots in the flywheel that heat up more easily because the metal has broken down from heat or some crap like that. I dont really know, I just know the last flywheel I had like that I had resurfaced for $30 and it worked fine.

After some heavy malleting, we got the flywheel off. Here is one closer pic, and a real close pic.

Thanks for all the help.

And yeah, what grit sandpaper should be good or doesn't really matter.

I'd reuse it. The flywheel in my REPU is a lot worse than that.

I hope it's okay to jump in here, being a noob

I may not be familiar with the rotary specifics of the flywheel, but I have done more clutch jobs than you can imagine.

I have heard from both camps on wether the flywheel surface should be shiny/machined or just slightly roughed up.
I have installed new clutched under both of the above, plus a couple that the flywheel wasn't touched at all.

Even with a few "hot-spots" on the surface, I have never had a clutch job come back, (well except for the one that I somehow put the t/o bearing on backwards ).

From taking a close look at the pics, I would just use a green scoth-brite pad to clean it up and then use about a whole can of brake cleaner on it. you have to make sure that you get all of the scotch-brite residue cleaned off.

good-luck.

Scotchbrite is good.
