Hello! Your operator is very similar to our 39-023. However, I'm not sure if your arm length will be the same as ours, which is 11". Look it over and see what you think! If your arm size differs, let me know and we can see if we can find a better alternative.

Thank you! This information is a huge help. So, we do have a part that I think will work for you, but there are a couple caveats. First, see our 39-139. This has a 9-1/2" long arm, but we measure from the center of the wheel to the center of the gear; I actually think yours is the same size if you were to measure it the same way, but it can't hurt to check.

You'll also note that the screw holes are on the inside, not outside. This means you wouldn't be able to mount it the same way as-is. Therefore I also recommend the 33-205 thread nut. You can use this to adapt the 39-139 to have a rear-mount installation just like your original. Would this work for you? Let me know if you had any questions or concerns! |
