Re: Changing speedos/mileage
I think there should be a way you can keep rolling the number wheel upward until you reach the correct mileage...

Re: Changing speedos/mileage
you can remove the wheel and one by one set the numbers, it took me 15 minutes to match my mileage, alsop i dont think the number wheel matters for mile/kilos. i think there is adifferent gear ratio inside for the two thats it

Re: Changing speedos/mileage
The early mechanical speedos are easy to adjust,....... Last winter I converted my step fathers dash to a full gauge set-up - it was a mechanical speedo and got converted to an electric Speedometer. Your car should also be electric.
I found it was easier to simply roll the odometer gears forward with a drill until I got the correct mileage showing on the odometer than it was to pull it apart and 'manually' change the reading by hand.
After setting the odometer in his replacement speedo to match his cars actual mileage, I re-set the odometer on another cluster all the way to Zero using the same method. ( The drill had a small rubber bit on the end of it. ) It took a LONG time to roll it all the way to '0' !!!

Re: Changing speedos/mileage
So if I ever find a 145 mph cluster for my 92 RS can it be rolled back or reset to the mileage on the old original 110?
