Flywheel Condition Opinion

[howeitsdone]

Wanting a second set of eyes on this flywheel. Sort of looks like heat spots but then again the blotches aren't 'blue'. Very smooth surface. I didn't find a surface variation threshold in the manual to even warrant checking that.

what was its performance before?

Looks like normal wear and tear. You can always take 500-1000 grit sandpaper and lightly go over it with an electric sander. I did that to no ill-effects.

Not quite sure how to gauge the flywheel performance. The clutch was at the end and I know that feeling which was what it seemed like. Smelled bad and the occasional slip (thud) when too much torque applied stationary. I know those are also bad symptoms of a flywheel, but if the clutch has no material then the same happens. Hard to tell.

Might just do that then. I was more concerned with the coloration since the surface is very smooth.

Doesn't look too different than mine.  Cost was around $40 to resurface.  This is one of those jobs that you might as well do while you're in there since the teardown is such a PITA.

New ones are about $60 from Rock Auto. I’d save the hassle of finding out it needs resurfacing/replacing after assembly and just buy a new one. But I also have a tendency to replace more parts than I need to because I don’t want to have to do the job again for a very long time.

Ended up sanding as suggested. I did a pass of 400 and then 800. Definitely no resurface, but it'll get the job done. Enough to get that rust off.

You're good to go.

 

I'd rather have a known good flywheel scuffed than to risk buying some unbalanced and reverse engineered piece of crap off the internet.

Some will say, probably correctly, that AX15 flywheels (OEM) have a slight concavity to them, and that they should never be refinished more than a light hand sanding else you'll ruin it.  The concavity part might be true, but I've had flywheels cut and reused them with no issues.

 

I'd blast that wheel with a can of brake clean, let it dry and then bolt the clutch together.
