crank housing

Sure, we actually carry a ton of operators in this style. I'm not sure exactly which one you have, but you can see our whole selection here.

If you aren't able to match any of our parts upt o your original, then I'll need a bit more information to narrow it down for you. Start by showing me one clear picture that shows the complete installation hole pattern, and another picture of the link arm fully removed and disconnected from the linkage. From there I will do my best to get a good match for you.

I'm afraid I still can't see the link arm. The frame obscured too much of it for me to ID. 

I have made a list of products that could potentially replace yours. You can look it over to see if any of these will work; we have detailed photos and dimensions on each product's store page that you can use as a reference. Otherwise, I will need to see your operator out of the window in order to narrow it down.
