Window crank arm

A quick learner from 08031 says:
I can open the windows but they won't close crank arm turns until they come out completely both left and right sides (2 windows) name on part says entrygard truth. Are these parts available and do I have to replace the whole operator or just the crank arm? All the teeth on the gears look good still. Thank you

Hello, thank you for posting,

Unfortunately the full operator will need to be replaced as it appears the worm gear is stripped out of the operator. Please start by reviewing the style and dimensions of the 39-035 and 39-036 operators to see how they compare to your original. I

If a new cover and handle are needed, take a look at the 39-107 and 39-114L. Let us know what you think and if you have any additional questions!
