... there may be some difference between the laws in the US and Canada on
this ... anything that deals with odometers tends to be tightly controlled
here. I know it is quite difficult to find the gears here south of the
border. Notice I said difficult ... I too have found VDO dealers who are
willing to supply the gears.
No matter what, by definition the plastic gear will break ... it is hard
plastic with a metal shaft friction fit in the center ... if a metal
replacement were available it should provide a permanent solution. I say
should because there are two failure modes on the odometer, one is that the
drive gear breaks and slips on the shaft and the other is that the first
wheel in the counter (the tenth's wheel you don't see) slips on the shaft
and causes the odo to stop ...
