This listing is for a high quality reproduction of the 'lipped' and chromed Inlet Ring and distinctive shaped bolt that were fitted to Amal Type 76 /276 or Amal 86/286 Stub fitting carburettors, and locked the carburettor to the inllet stub.
We offer this inlet ring in two sizes - this being the larger size (See Item 1173 for the smaller size) -
The inner bore of this ring (the main bore, not the lipped ring) is 1 7/16" - i.e. it will fit over a carb where the outer diameter of the inlet stub is 1432"/36.4mm
These rings are UK manufactured to a very high quality for us - made from brass as per the original pattern, then chromed. The design is as per the original - with an inner lip that fits into a correspoinding lip on the carburettor body. The specially shaped (shouldered) bolt is CNC machined by us to the original disttinctive shape in stainless steel, then the end is polished - so that too looks like it is chromed. The head of the bolt is milled to the correct imperial spanner size of 1/8" Whit (we mill this head, as it is becoming increasingly difficult to obtain it in stainless steel), which gives a very crisp finish - important, as it is often this hex head that suffers on original carbs - as they are often overtightened with use. As a final design point - we have also replicated the opposite threaded end on these small bolts - which was rounded, as it protruded from the threaded end of the ring - presumably to avoid it catching on cloth's when the owner cleaned the bike.
These rings and bolts are often damaged and have lost their chrome on original bikes, with the bolt head often chewed - and as they are in a prominent and visible position on the bike - replcement with this item can transform the cosmetic look in that area - as well as allowing the carburettor to be properly tightened to the inlet stub!
Model Fitting: The ring shown here has a 1 7/16" bore size, and fitted over the stubs of Type 76/Type 276 Amal carbs fitted to many Norton OHV/SV models. The carburettor shown in the photo is from a late 1940's Norton OHV model and has the correct stub outer diameter for this ring.
It is also the correct diameter to fit Amal 89/289 carbs fitted to Vincent Models (I confirmed this by measuring the original Amal 89 carb fitted to my Vincent Comet).
No doubt it will also be the correct size for numerous other margques of the 1930's-950's that fitted Amal 76/276 or Amal 86/286 Carbs - But please check the outer bore of your carb inlet stub before ordering to check - and note that we also sell Item 1173, which has the smaller bore of 1 5/16"
