Need the whole crank assembly for Norco casement windows...

Question

Please see the pictures, the crank has come completely out and we can not figure out how to get the worm gear/crank lined up and how to tighten the screw that holds the shaft in. These are on my girlfriends windows so I have no history but it seems like the retaining piece (laying beside crank in picture 2) is possibly cross threaded and not sure why they back out, that is why I am thinking the easiest thing is to replace the whole assembly. Open to suggestions. Thanks

Your operator's gears are stripped out, which is why the bore is backing out like that. You need an all new operator.

Yours looks close to our 39-083. Just check to make sure that the "elbow to elbow" measurement on your part is also 21-1/2". If it is, then you should be good to go.
