Hello Webby, Only just seen your post so you've probably sorted it by now. There's nothing too odd about the pre-AMC Norton clutch although the rubbers are always fun.

Something must be wrong because it's usually straightforward to pull the pressure plate down. Are you doing it in situ ? Does it fit together if you try it 'loose' ?

It would be handy to know what literature / drawings you have. A photo might be useful too.

Hi Webby - A mate of mine recently renewed the clutch plates on his 51 ES2 and had found there was one short. He added another which resulted in the same problem as you have. I had heard that the new cork plates were a little thicker than originals and that could be the problem!! Did you renew 'em and can you compare with the old ones for thickness?

Further to my last post about the clutch dilemma, look at this link to the same problem and discussion on a Triumph site only 6 days ago...

Hello 79x100
Sorry for the delay in responding have been out of town.
Yes it all seems to fit together loose.
Looking at the manual I have just obtained i now realise i am missing
the clutch plate retaining clip & cover.
I cannot see how either of these parts would stop the pressure plate being pulled down.
The manual is titled
Maintance manual & Instruction book
for motor cycle solo 16 H 490 cc s.v
Norton motors LTD

As for sending a photo, mate i,m just an old plumber i will have to waite
for my teenage daughter to get home


cheers Webby

Hello Webby, I have a copy of the book and diagram that you're looking at. There have been several revisions to the Norton / AMC clutch and I have seen different lengths of spring studs and cups. The trouble is that I can't say for certain which is which.

As you say, the problem doesn't lie with the lack of clip ring or the plate cover (The cover is just a band to keep oil off the plates as the original cork type don't like too much oil) The later clutches had bonded linings which solved the problem. The Norton clutch was designed to run dry and didn't take too kindly to oil.

THe early type drum with pressed in corks is best modified if you want reliable clutch engagement.

Ken McIntosh in NZ is good on Norton transmission parts (and has his own 1939 WD 16H in addition to all those Manxes).

Have you seen Rob van den Brink's WD Norton site ?

http://www.wdnorton.nl/

I'm assuming yours is a WD model (does it have a four digit frame number with a 'W' prefix )?

The Unapproachable Norton Commando

At the end of 1967 the Norton Commando was announced.

The Norton Commando was greeted with a certain amount of scepticism because on first sight the commando appeared to comprise of the old Norton Dominator twin cylinder engine mounted at an inclined angle in a set of new cylinder parts.

It was not realized that the new Norton Commando Isolastic method of engine suspension damped out all engine vibration and produced a machine which had uncanny smoothness for a vertical twin. In due course the critics were silenced and the Norton Commando had the distinction of being regarded as the first of todays so called superbikes. There can be little doubt that the original design concept of the Norton Commando has proved correct, since comparatively few modifications of any real consequence have been made since production commenced during 1968.

Now nearly 40 years later Norton Commando riders like us are a breed of our own, and as far as we are concerned its still more fun to go for a blat on the old Norton Commando, and fast. As a Norton Commando owner and enthusiast, my goal here is to promote and give credit to those who keep the Norton name going.

It is more deserving to give credit to the Commando itself, for after all these years it continues to be respected. The original Commando designers like John Favill are those who deserve the credit for developing this incredible motorcycle.

The Norton Commando Roadster and Interstate of the late seventies, never died. Although the Norton Villiers factory dispersed the tradition lived on. Today Kenny Dreer in the USA is developing the new 952 CC Norton. What a great looking bike this is, and its engineering is still based on the original layout. It will be interesting to see how the new 952CC Norton does in todays tough motorcycle market. One thing is for sure, I would own one if I could afford it.
