Burman clutch setting

I don't think it's a Burman clutch unless it's been modified - it's a Norton one. I think it's the same as my 1952 ES2 - the 3 bolts should be tightened down fully. The flat head on the clutch actuator helps to prevent the pressure plate from tilting - it's a much better arrangement than the later ones with a central adjuster.

As with most clutches, you want it set up with about 1/16" slack in the cable so there's no load on the pushrod when engaged.

1950s boxes were essentially Sturmey Archer design as used on pre-war Nortons, but Burmans actually manufactured the later ones but to the Norton specification. Even the later "AMC" type box was essentially that same design going right through to the latest Commandos.

Having problems setting up my 56 Dommies laydown clutch, having even more difficulty finding a manual that sets out the procedure. The unit is fully assembled and I would really appreciate step by step guidance on the set up or pointers to where the info is available.

Hello Ron you could have a set of after market clutch springs fitted that are much more heaver than the original set so try getting a set of springs that are a bit softer you can tell by the thickness of the spring this may be triail until you find the right set that work right for you, and to set up the clutch cable there should be no slack in the cable all adjustments are done in two ways one is by setting the gearbox arm on its lowest point with no adjustment On the gearbox end adjuster, Then adjust as necessary on the gearbox cable adjuster job done yours anna j

I can't agree to having no slack in the cable at all. That would mean constant contact between the pushrod end and the operating scroll and we all know how that ends up.....

However it should only be 1/16" or so.
