casement window cranks stripped

Question

Most of the parts that are problematic are the cranks. Is there a way to replace this unit without replacing the entire unit with the arm? I did watch the video about how to replace the entire unit. 3 are the type in 550. Another stripped crank goes to a standard right opening arm like 551. The rest are stripped as in 546.

Hello. It's a little difficult to say which replacement operator will work without knowing the measurements of what you have. To start, you may want to take a closer look into the 39-083. You want to consider the "elbow to elbow" measurement when looking over our part. Get back to us and let us know if this part can be used as an alternative.
