Hi
I can't find the specifications for new and wear limit for a NA clutch disc. Anyone who has that spec handy?

Check the specifications document not super clear, but should be an indication

New 10.1-10.4

Wear limit: 8.5mm with asymetrical wear

Lateral run-out,: max 0.6mm with diameter 200

Thanks, I'm calling 8.8mm good enough!
Lateral run out... probably good, don't want to know!

I got a little worried, this engine had washers (normal washers) underneath the pressure plate spacing it out ~1mm. I was thinking that they had used the wrong disc somehow and tried to compensate for that.

I'll try to lift the engine back in tonight if things turn out as planed.
