Dave, thank you that is great, just what I need.
Most importantly, I was desperate for measurements/thickness of the friction plate when new. 7.2mm and my measurements are 7.2mm across all pads Woo!
So the Diaphram Spring is non selectable it seems.. I have a 68-110R with cerametallic plate which means I can run up to 256lb/ft of tourqe through it... bam.. no issues there.
A release load of 335kg
So, I noticed on MH pdf he had some clutches stating "clamping force", I do not see figures like that on this spec sheet.
Where has this 'blue' 170 nm diagram spring rating come from?
