Salvageable?
 
Hey guys, I have a FM Level 1 clutch that I bought for dirt cheap. PO says it has "4000 miles".
Is this salvageable or trash?

I'd guess that the friction disk is ruined. It looks like they put wayyy too much grease on the trans input shaft splines, and it contaminated the clutch. The pressure plate I guess could be resurfaced. I'd guess that you'd end up paying ~$200 for a new friction disk & resurfacing the pressure plate. A new FM clutch is what, $400?

Yeah, about that much. I wonder if I could buy just the friction disk from FM if the pressure plate could be resurfaced. I live near BogusSVO so I could give him a call.

Brake cleaner will degrease it.

So just break clean the friction plate and it should be good? I will obviously resurface the pressure plate.

:) That looks like the one I almost bought.. 1.6? I'm pretty sure you could make it "work" with brake cleaner. You will probably have to clean an wipe it down repeatedly. From my understanding though with an organic disk you will never be able to fully remove the contamination, due to the material being so pourous, when it heats up the oils will just come to the surface again. Could be completely wrong but that's what the ol man told be awhile back...

If it works it works. If it doesn't how much is your time worth to R&R the clutch? I don't know your financial situation but I've seen a hell of a lot worse. You either do a good job getting the oil out of it or you don't.

Chlorinated brake parts cleaner works better than unchlorinated.

You can also use denatured alcohol available at Lowe's in gallon cans. You could soak it in a shallow pan after the brake parts cleaner if you want.

Allow to dry thoroughly for a few days before installing. Maybe warm it with a heat gun or hairdryer.

It depends on your financial situation. Confessions of a broke college diy mechanic.

I am going to try that tonight. Now for the pressure plate can it just be sanded down with a certain type of paper? Or could be be “roughed up a bit” to get rid of the glazing? I’m also a broke college student with a decent enough job, so I don’t want to spend the money if there is a reliable way to do so. Edit: I meant that if there is a DIY way to do it reliably, I’ll do that before taking it to a machine shop unless I have to

Scuffing is what is important. And degrease/deglaze it too.

alright, I’ll see what I can do with 800-1000 grit sand paper. I’ll let you guys how how it works.

How much do you enjoy pulling the trans?

I wouldn't use that.

about as much as any other dude lmao. What would you use?

Take your pick. I upgraded to an FM2 for my power levels. Works fine. When I removed my 5 speed for a 6 speed I didn't even chance my old clutch and just bought a new one. Put the old one on the shelf for a spare.
