Replacement Crank Part

A quick learner from San Anselmo, CA says:
Hello,
The crank on our window is broken. I have included pictures. There is no brand name mentioned, just the number 45054 on the inside of the crank. What part(s) do I need? Can I just replace the crank or will I need to replace the entire thing? Thanks very much for your help. Matthew

Hey, Matthew. Based on your first picture, it looks like the gear bore came out with the handle. This is not supposed to come out, and I'm afraid it cannot be repaired. You will need a new operator entirely.

We should be able to identify what you have, but we will need to see a picture of your complete operator unit. You can do this by either removing it entirely, or by opening the window and showing us a top-down picture of the mechanism, including its arms. Either way, we need to see as much of it as possible in one shot, preferably the whole thing.

Thanks so much for your help. Here are some more pictures. Let me know if you can help me figure out what to replace it with. Thank you!

Thank you. I have received your pictures, but they appear to only show us the tip of the operator arm. We need to see the complete operator unit. Like I mentioned, in order to identify this part, we have to see as much of it as possible in one shot.

Perfect! This looks a lot like our 39-348, however our arms might be a little bigger. It's tough to say. Look over our measurements and see what you think.

Hi,
It looks really close. If anything the arms on mine is slightly longer. It's still in the window so an exact measurement of the arms is difficult. The guide bar is 26 3/4 inches long. So, does it have to be exactly the same as what I have, or just fit within the guide bar? Also, is there any reason I can't use my old crank handle on the new arms? Thanks so much! Have a great day

Having the exact match would definitely be ideal, but there may be some wiggle room. I recommend removing your operator form the window to get the most exact measurement you can.
