Hi,

what size are and the bolts from the pressure plate to the flywheel.

Ian

M8x25 Gr8.8

Thanks Mark,

Not alot of info after reading it again.

Pinto flywheel.

Ian

If you need more detail:
M8 x 25mm long rolled thread precision bolt to Australian Standard AS1110 grade 8.8 (rated at 80% yeild stress of the bolt, 800MPa)....Recommended torque for black bolt without lubricant and preload 65% proof load of the bolt (general engineering practice) is about 20-22Nm, for more accuracy then a strain gauge should be used. Yes most of this is unknown, but very important. Should you require further explanation then please contact me via email...As a guide I have 530Nm at the flywheel from a 2L engine with 6x M8 bolts holding the clutch to the flywheel and they are fine for this load....

think he meant that he didn't put up enough info.

Yes I know and assumed ford 4 cylinder flywheel to clutch but it was also fun to write a trilogy[:u][:x)]

bolts may only be 16-20mm long, depends on the flywheel thread depth...

Thanks alot Mark.

Theres no harm in providing useful info.
