Flywheel gear ring 130t - 12 volt

Very easy to replace on a lath. Turn your old teeth down till 0.3mm less as the inner diameter of our flywheel gears.  Put your flywheel in the fridge and heathen up your flywheel gear in an oven or on a cooking plate. Slide the two together en let cool down. This is what they call an assembly with a pre-tension of 0.30mm what every machine shop should be able to perform.
