not been on the dyno as yet, just finished running it in, should be good tho.

i,l tally up the stack up i have then and see if i can give it more clearance before i invest
many thanks

I'm confused now, are you saying you are running 4 or 5 thin green plates in a deepened basket? If you are running 4 thin greens in a deep basket then you will almost certainly have too much free play, and you can try to take up that excessive free play with an extra plate.

It's probably LESS clearance that you need, too much clearance means that the springs are at or beyond the point of maximum tension.

arh...when i say deepend i mean where the ears of the plates sit..i know some crownwheels are like this as std....this one wasnt...think i copied sticky,s book on this one.not the actuall depth of the crownwheel itself(sorry for the confusion)
yes 4 green surflex plates....heavy duty springs and a centre spring to boot

OK, i think this might be your problem. When you put the clutch compression tool on to the clutch/pressure plate and wind it in all the way in, the clutch plates should then be 'loose' in the crownwheel.....get hold of an 'ear' on the top/nearest clutch plate and 'waggle' it. It should 'waggle' no more than 2.5mm.....

If you find the top plate 'waggles' a lot and is very sloppy.....either fit more plates or thicker steels until you reduce the free play (waggle) to under 2.5mm....but no less than 1mm.

Ok?

roger that
thank you
