Norton Big End Assembly and Parts
I have recently expanded the range of Norton Big End parts I can supply. I can now offer both 500cc and 350cc Norton International BigEnds, as well as Racing International (30M), SOHC, early DOHC and Late DOHC Manx BigEnd assemblies.

Finally, I have just had commisioned a batch of the correct 30M and Manx large Hexagonal nuts, as fitted to all racing crankshaft assemblies (SOHC and DOHC), before Norton swapped to using castellated nuts with their shortstroke engines. These Manx nuts have the same profile as International hexagonal nuts, but are wider, so they spread load over a wider area. Contact me if you need more detail or are not sure what Bigend your engine requires

Back In Stock:
All these important nuts are now back in stock. As imperial sized hexagon bar is getting difficult to obtain in high tensile steels, I have had all of these CNC mchined from solid EN8 round bar, to ensure they are fit for purpose. Being CNC machined - they look nice as well!

New Castings in Progress
As you can see from the photographs above, I am in the process of manufacturing more of the main SOHC Norton engine castings. All of the above have had trial castings in magnesium, and are now in the process of initial machining. As you will appreciate, ensuring the finished product is correct in detail and of the required high quality is a lengthy (and costly!) process. With this in mind I would not expect to have anything ready for sale until Winter 2009, but watch this space, and let me know if you are interested and require more details.
