One of our engines has a nice mechanical rev-counter, driven by a flat belt from the crankshaft. It is pretty conventional but at the end of last season it stopped working.
Having got round to stripping it down, we find that there is an air-vane damper which limits the rate of change in the needle movement, stopping flutter etc.
The vane had come off its shaft, and the shaft has lost one of its bearing ends. The shaft and gear are all one piece and I think that a new shaft end could be fitted into the existing gear, but not with what we have at the factory!
A picture of the remains is here:
I really need a 'clock guy' with the necessary small lathe to be able to drill the end out and make and insert a new pin, to fairly accurate levels of workmanship.
It's not a beer token job, real money is offered plus postage both ways.
