Our old crank is in the bottom left of this pic. The new one sent us is on the upper right,but it does not retract far enough into the closer to to completely shut the window. What one do I really need? part # is 39-089
Thanks

Can you uncrank the operator a little and show me a clear picture of the gear arm? That would help us determine what may work.

Hi Toom,
Attached are the pics you requested \. The old system is below and the new one is on top. we need to replace the old one on the bottom. As you requested these are better pics of the lower crank arm.
Hop[e this helps

Yep, I thought so. I recommend our 39-187, instead. As you can see, the gear arm is a different shape. I know it's not obvious at first glance, but if you look closely you'll see that the 39-089 you bought has a "Z" shaped arm, while your old operator, and the 39-187, have a "W" shaped arm.
