Window crank
Should the part above replace the part in the photos?
Thanks for reaching out to us. Yes, our 39-253RB indeed looks like a good match for your old operator as long as the specifications match up and it uses the 39-529 track slider. Your next step should be to confirm that before placing an order.
We also sell the 39-452 compatible cover and handle in case your old one is built into the operator base and can't be removed.
I attached a few more images.
I think that the track slider is different though.
Let me know if you have something like the one in IMG_4481 and IMG_4474.
In IMG_4467 there's a number 31858, is it related to the mechanism in any way?
Thank you.
I think we may be referring to two different things. The 39-529 track slider is designed to be connected at the end of the 39-253RB's arm. You may want to remove the operator to confirm.
The track slider in your photos appears to be connected to the hinge which is a different part. We don't sell that part separately so you'd need a new one such as the 36-048 if the specifications align and if you replace the top and bottom hinges at the same time. Take a look and see what you think.
Let me know if you have any questions!
I'm still not sure where the 39-529 goes..
