Norton clutch plates

Hi all, Hope everyone had a good Christmas.

I am on the search for a supplier of clutch plates for the Dominator. I am usung the original basket and pressure plate. My dad says he would like the fibre plates with teeth inwards and the metal plates with outward teeth if still done as all i can find is second hand ones all with inward teeth. I have got the Norvil book but was looking for other suppliers. I am also looking for cush drives and the mushroom bit that goes on the end of the pushrod. The bike is nearing completion as i have just got a few more bits for it for Christmas.

Cheers Kevin

Give Mick Hemmings a call (details below) he's more of a Commando specialist, but chances are he'll know the right people to get in touch with.

Hi, I always used Jawa speedway friction plates in my norton clutches. Speedway riders are a conservative lot and for years and years-certainly untill very recently-the good old Norton friction plates with the teeth outwards were copied by JAWA and NEB for their clutches. I would make a mushroom lifter from an old exhaust valve-easy to find in most workshops. I often wondered why Norton used friction plates that were either way. In practice, having used both I never found any significant difference. Lifting the clutch on a well made mushroom certainly helps a clutch lift much squarer. The stupid Triumph idea of lifting the clutch on a quarter steel ball means you are forever adjusting the springs to get a clean even lift. If you need advice on the different types of speedway friction plates currently in vougue ask Alan Bellham at Speedway Services. Good Luck.

Hello Kevin! Sorry I can't offer a supplier for the solid fibre type of plates you are asking about, but if I may offer some advice based on my experience??? You say your dad would prefer this type of clutch plate, but in fact the type of clutch plates you can use are dictated by the type of clutch you have! The early clutch, that used the "solid" fibre friction plates, with the dogs to the chainwheel and the plain steel plates with the dogs to the inside, ran with a chainwheel with fibre inserts inserted in pressed out windows.The hub had a plain back-plate. The later clutch had steel friction plates with bonded-on friction pads and dogs on the inside, the plain steel plates had dogs on the outside. The chainwheel was plain, without friction material and the hub had bonded-on friction pads. The chainwheel and hub types cannot be interchanged directly and must be used as a set.
I hope this is not too complicated, but first of all you must determine what type of clutch you have! If you have the early type and it is not complete, I suggest you get the later type as it is much easier to set-up and you don't get problems of the inserts loosening in the chainwheel and the chainwheel floating about, causing chain alignment problems! Also, the plates for the later clutch are readily available from most Norton dealers. I would suggest RGM of Cumbria over Norvil any day. I hope this info is of use to you! Richard.
