Lightly toasted clutch

Got the transmission out of the !!!error: Indecipherable SUB-paragraph formatting!!! , and yeah it definitely saw some heat. The f lywheel has about the same glazing as the pictured pressure plate . I’m really surprised it never made any clutch smells. Surprisingly the disk still has a bit of thickness left (just barely)

Rather than mess around with resurfacing the flywheel and pot entially ending up with a bit less total clamp force, I decided to use it as a chance t o upgrade to a lighter flywheel. I ordered that, a real main seal, and a few fasteners that I expect to have to replace. This will go with an Action clutch 2800lb pressure plate and a mk3 turbo supra stock clutch disk.

Hopefully in about 2 weeks I’ll get to experience it in all it’s sleeper-ey 1j turbo glory!

hows the throwout bearing?

cable or hydraulic clutch?

if hydraulic,  might want to do master and slave cylinders too

Lightly toasted?

Mmm, spread some compound butter on it and serve it with some eggs.

Throw out bearing looks good, getting replaced anyway for completeness. Hydraulics seem functional , no apparent internal bypasses. Thankfully, those can be replaced easily down the road if needed.

Manual transmissions are another of those car parts where I know what all the major things are and roughly how they fit together, but I don’t feel like I completely understand how it operates (I couldn’t say exactly how the diaphragm spring separates the pressure plate and clutch disc).

Neat to see a burnt-out clutch and pressure plate, though. Is the pressure plate going back on as-is?

Oh no chance. Everything going back in is brand new. Flywheel, clutch, and pressure plate. Since I didn’t find anything particular failed, I’m going on the assumption that the total system stack up is to blame for the low clamping force.

If you want to see a cool failure

It’s certainly easier to explain than automatic transmissions where power goes in, magic happens inside, and then the wheels move. Or alternatively power goes in, magic happens inside, and then gears come out the back.

can probably serve the eggs raw and the clutch plate will have them cooked in no time.
