Are my old casement cranks repairable or replaceable?

I need to know if the crank handle on my old malta casement crankout window is repairable or replaceable? If so, I may need to send you a picture since I don’t know the model or the age.

All window hardware is replaceable if it is still available. Casement operators are not repairable. The most common failure is broken gear or teeth or a stripped handle post. When the retainer pulls out of the spindle socket it can not be repaired. The entire assembly has to be replaced. The handle is usually a separate part and can be removed by loosening the set screw on the underside.
