The cranking mechanism on one of our Anderson casement windows has been stripped and the housing cracked. What do we to do to fix this? It is in a bank of 9 windows that are al least 20 years old

If the worm gear is coming out of the operator, then the gears are stripped and the whole mechanism will have to be replaced. I see you were looking at our 39-094. This may be a match, but it's hard to tell from your pictures. You only show the base. I would look over our dimensions and measurements to confirm that everything matches up to what you have now.
