PO's Clutch/Flywheel Butchering: How Bad Is This?

Yes re-used nuts are pretty much standard, mine was worse than that one when I did my clutch.
A light reface of the flywheel might be all that's needed. Have a look at mine on YouTube under 'thehelidoctor' I have produced a full start to finish clutch change series of videos. You will see me cleaning up my flywheel which had the lightest of surface cracks that I blocked out, yes that's right I did it the old fashioned way, didn't even get it machined, that was 8,000miles ago and it's been smooth as silk ever since.
The bell housing gunk looks fairly normal since most people never clean it when they are in there....lazy I guess.
As for the rear seal, is there actually a seal in there? It does look a bit odd in the picture....

 

The seal will pull out with a hook. The pilot bearing I used a blind hole bearing tool to remove it. The I tapped both back I with suitable tube.

 

This doesn't look to much different then the one I pulled apart nor any different from other manual transmission clutch replacements. Also depending how the nut came off and if the person who replaced it did a little straighten it is OK to reuse. I took a punch to hammer out the swage and cleaned it up after it was off. The flywheel may or may not clean up but I would take it to a machine shop and have them do a few light cuts to see how much you need to take off. Someone here should be able to give you min thickness and if it's clean after the cut then use it. As for the seal it looks like normal wear so pull it and replace it. Should be no contamination to the crank or engine oil. Just replace the pilot bearing . As for what the PO did I don't know but to me this is normal wear and if anything it should have been adjusted but as soon as it started to slip then it was time to stop and replace. What did the disk and PP look like.

 

Whats the big deal? With the exception of the nut it looks much like every Ferrari I have done a clutch on over the last 38 years.

Where is the butchery? Yea, a new nut could have been used but exactly where did their method go wrong or create trouble?

Cut it off with a dremel tool? Why not just use the factory method and turn the nut? That little peened dimple isn't going to stop you or cause damage.

You don't see an oil seal? You do know what an oil seal looks like don't you? I guess not.

The bearing is supposed to stick out. It centers the flywheel.


What were you expecting when you started this job, polished parts in perfect condition?

Based on what I have heard so far I think it best you leave this job to someone who has a clue.

 

A clutch on a 308 is a damn durable item too.

 

You did a nice clean up job. Clutches are dirty work. Your machine shop will verify if the flywheel can be surfaced but yours does not look out of the ordinary. The nuts can be reused but I prefer to replace them. I also suggest cleaning the snout on the input shaft as they are a close fit with the pilot bearing and any residual dirt with cause an interference fit.

If the flywheel is bad assco make and aluminum one that looks gorgeous. I think VonBarron is using on on his car.

 

The butchery would be if all your gears were wasted from not torquing the ring nuts properly, I am now a leading clutch expert, behind Ben of course. Well not literally behind Ben. I like girls. I'm not judging you, I just like girls is all

 

Oh and retorque all the nuts behind the flywheel...... Or else

 

Ha
And I butchered the flywheel manufacturer. Aasco. Red faced at the moment but that will pass

 

They did not have "the tool"

 

That one is done, IMO.

Think about the personal harm that a flywheel would make, breaking apart.
Drag racers don't wrap a Kevlar scatter blanket for no reason!

I shop for a used one from a hair dresser's GTS.
They hardly use the car, unlike a GTB owner.

 

I guess it could be rebuilt with some type of plasma resurfacing, but seriously I found a used one with OUT the cracks for about $200.

You are going to spend that quickly trying to fix that one.

Small cracks are the start of big cracks.

 

Hey Justin, I agree it's not that any damage is done re the nut etc, it's just a sloppy attitude to the job that gets ones 'Goat'.
I wonder if the Ferrari garage would have re-used that nut if the client was watching.....or it was on some pricless Bugatti.
Anyway re the flywheel, just get it skimmed and crack tested, we do it with helicopter parts as condition checks all the time, crack test that is. Anyway it's only a lump of metel, it's not rocket science. ;-)

My flywheel was so overtemped by a previous owner that the ring gear was slipping. A good used one cost me about $200 on eBay plus I had to have it machined.

If people want $900 for a used one n eBay, go for the Superformance one linked above or Din Parts has one without a ring gear for 498 euro.
Ferrari 308 GTB/GTS: Engine: Engine Block: Ring gear & flywheel: Flywheel 308
( I would probably get the Superformance one)

One more option..Billet aluminum flywheel:
AASCO Lightweight Billet Aluminum Flywheel Ferrari 308 GTS 3.0L 77-84
$695 but not sure how well it would work on the street.

 

Aasco works great for the street, also rebuildable, $666. My experience was a pleasure. They even sent it to me before payment. If you want a look see, check my post

 

That's not a bad ring nut, this is a bad ring nut. I'm sure they used the Ferrari hammer and chisel.

Take look at exactly where those flywheel parts would go in relation to the car, and you, if it broke apart.

Right up the center of your back.

Google flywheel explosion pictures to see what one does.

What is your answer?????

Could they reweld it???
I mean, economically, I could run beads cross it all weekend, but that's not the same.

I replaced mine, no questions asked.
