NC30 89' Clutch problem! please help

[majormadass]

wondering if anyone can help me please.
recently my clutch started Dragging, so i checked the clutch
and needed new friction plates, i put my new friction plates in recently, and for some reason the clutch doesnt work at all? any ideas? then i tried again 30 minutes later, put it in first gear and the clutch 'Bit' but very late, then tried it in 2nd gear and it wouldn't bite, tried it in 1st wouldnt bite? so very rarely it will be, and mostly not at all? can someone please help me?

me and my brother have already put the clutch back as according to friction plate, steel plate, friction plate etc....
we adjusted the tension of the clutch, and also made sure the actuator arm was correctly in place fully, the clutch has tension in it, but just doesnt seem to bite, only when it feels like it, so its unrideable :S but new clutch kit :S i was out on my bike earlier, with the old clutch kit, ran ok, all ive done is change my clutch kit, oil and oil filter, and the clutch wont bite :S

You can check this http://i530.photobucket.com/albums/dd34 ... age1-1.jpg and following pages for assembly order & procedure, if everythings in right, and its still not biting properly the plates obviously aren't compressed enough by the diaphragm springs, does the clutch lever feel very light?

BTW "friction reducing" "super lubricant" oils will cause the clutch to slip and arent suitable for a wet clutch..

hiya mate, but them back as said, my bro said the springs are fine dont need raplacing, and it bites but very rarely then mostly not at all, the clutch lever is average just like a normal clutch would feel, so there's definitly tension in the lever etc :S just wont bite? yeah no worries about friction reducers and stuff, i got the correct oil and stuff mate, any other ideas????

The Hayne's suggests for a slipping clutch:

1) insufficient cable freeplay
2) friction or plain plates worn or warped
3) Diaphragm springs weak from heat damage
4)clutch release mechanism defective
5) clutch center or housing unevenly worn

inspect all these areas(obv u got new plates) for any signs of damage..
Check the clutch nut is torqued to 85Nm.
Go through the haynes re-assembly procedure again to ensure all parts are back as they should be.
When the clutch does bite, is the bike warm or cold or during both? Does it bite close in, or far out?

cables fine mate. checked plain plates while checking friction, only friction plates needed replacing buddy, diaphragm springs are fine, and so is clutch release i think, cant see it being unevenly worn, as it was working earlier in the day with my old clutch plates as i went on a ride :S, the bike was both, once cold once warm, and it bites very far out mate

Thickness of new friction plates should be 2.92 - 3.08mm, sure you got the right ones?

Diaphragm spring height(3 on top of each other on flat surface) should be 4.8mm min.

If you put the old ones back in its fine you said?

Check to see if assembly with new components sticks out to the same point as with old plates...

Requires a bit of fiddling but this cant be too difficult to sort out...

yeah they measure 3mm exactly
Diaphragm spring height(3 on top of each other on flat surface) should be 4.8mm min.
diaphragm spring height is 5m overall

yeah the old friction plates etc, seems to work fine, but the clutch drags, why we bought new friction plates in the first place
Check to see if assembly with new components sticks out to the same point as with old plates...
yeah they do mate

managed to get it working for about 30 seconds properly, then it went again

any other ideas

As Gringo says you'll need to take some measurements.

This might help:

Cammo matey, we measured everything, and checked it with my haynes manual, everything seems to measure out correctly pal, any other ideas

If the problem started when you swapped the plates and oil i would guess it doesn't like the oil.

Did you use a bike specific oil ?
