Some years back I bought a replacement ring gear from John Craddock so you might try them. I've also found Dingocroft helpful. Both in the UK.
I have an original workshop manual and parts catalogue for this model. If you PM me with contact details I'll send you scans of the relevant pages.

I had one & also a complete F/Wheel , have not seen them for a long time though . [bighmmm] Have to have a think were they were .[bighmmm]

Gentlemen,
Thanks for the advice and help.
Firstly, the Series 1 flywheels are one piece and never had seperate ring gear. The flywheel cannot be rotated, as suggested, as it is fitted with permanent dowels.

However, there is an answer to this. I got in touch with Ian Cox of Cox and Turner in the UK yesterday. They offer a flywheel repair service, but postage of the heavy flywheel to the UK and back again would be prohibitively expensive. He suggested that he can supply a brand new ring gear for £78 and will include the engineering drawings required to machine off the old ring and set the flywheel up to take the new ring gear.

So I then visited Performance Modifications, in Perth, who are reboring my block and prepping the head , and they are experienced in flywheel machining and can certainly machine my old flywheel and install the new ring gear.

So that seems the most reliable and cost effective way of restoring your flywheel and ring gear.

Sounds like you have a solution and an engineering company that can machine to get the correct shrink fit.
I forget where I got the figures from when doing mine but I did have to borrow a very large micrometer.

hi i have second hand fly wheels here jim

I can get what is effectively a brand new one by matching mine and fitting new ring gear. I think I would rather do that than risk and unknown one.
Thanks for the kind offer though Russell.
