Yes, 1st check clearance \ freeplay, adjust "according to the book".

Procedure in the owner manual > http://www.a7a10.net/forum/index.php?topic=454 & in http://www.a7a10.net/forum/index.php?topic=1475.0

If not already done, a general inspection of all parts of the clutch is recommended.

btw... Bike year? Clutch type? nice to have info available (see http://www.a7a10.net/forum/index.php?topic=419.0)

if the adjustment is right then next step would be to adjust the springs in the clutch, say wind the adjusters in 2 turns, if you have to take primary case to do that you might as well check the plates are not worn out

come:to:think of it, maybe before doing anything with springs check there is not much oil in the primary chain case?

Yeah, assuming you have the actuation adjusted about right then you're going to want to try winding the nuts on the springs down. Trick is to get them just enough to avoid slip but not so much you need a gorilla grip.

To my mind it's a PITA because you've got to pull the chain case cover, with it's gasket; and to do that you'll likely be removing from that side the exhaust, footrest and brake pedal.
If you are going in and you don't know the state of the clutch components then I guess you'll at least pull the plates out for a looksee.

My 6 spring started to let go as soon as I'd finished running in and started winding on a bit. I did the adjustment by running with the chain case cover off until I had it right. Then buttoned it all back up.

Have you overfilled the chaincase? The plates could be oil soaked.

Hi cyclebutch not everybody needs to remove the exhaust and peg to get the case off.......I have but a mate doesnt cos his exhaust header sits lower.....and his peg is not bent?

and some cases have an access plug for the springs?

right then have stripped the clutch down (tried atf first but no joy) upon inspection 4 springs one longer than the others looks like someone has tried to stretch them, so ordered some new ones also a set of new friction plates fore good measure, oh and a new gasket
just need to know something do you put the gasket on dry or use some sealer with it ? thanks

If it did not leak before and had no gasket sealant you may one of the lucky ones and have flat surfaces and not need sealant.

I like a lot of people have to try very hard to make the primary chain case oil tight, I make my own gasket out of 0.8mm thick paper, and use loctite flexible master gasket applied to the both mating surfaces, I also have a couple of case bolts with the heads removed to assist in sliding the case into position without messing up the sealant.

I use rubber washers under the bottom bolt heads as they leak on mine.

I use sae 30 briggs and stratton mower oil in the case mainly as its red and you can see whats leaking!

There are quite a few different ways to seal the case some manage with just silicon and no gasket.

Its important to remove all old sealant without scratching the mating faces, which is why using a gasket with no sealant and just grease is best from a time saving view, if you can get it to seal ok doing that.

just my luck clutch plates came today along with springs, springs are shorter and clutch plates don't fit,
my basket has 10 slots in it the plates have 7 tags the supplier seems to think someone has fitted a triumph clutch.

Hey Derek,

I guess there's a lesson to be learnt there but sometimes even correct parts need fettling to make them fit.  However, I believe that the Triumph 4 spring clutch was originally fitted from 1958-on but previous owners chop and change bits over a period of time so you need to know the differences.

A parts book is always good to have so you can order your bits by part number.  They are available from most spares suppliers or from Ebay.  You would probably notice the difference in clutches doing it this way.

I'm sure that you will be able to change your newly acquired parts for the correct items if you've used a reputable dealer but it still doesn't doesn't help when you meet up with this sort of thing.

Good luck,

Beezageezauk.
