Good morning. I am in the process of replacing a Swisco Window Dyad Crank, 5" and see that there are 2 like parts - 39-089 and 39-187, the exception being the crank arm has a different zigzag shape position. Which Dyad part number between 39-089 and 39-187 should I order from your parts department on your website? Please advise when you are able to do so. Thank you. I appreciate it. Be well. Alan.

I can't tell what shape arm you have. There is no photo of the arm. Take a look at your arm and choose the operator that bends the same way.

Good morning. Thank you for the e.mail of Friday. I appreciate it. Attached are additional photos. I hope that you can now decipher which part I need, that of 39-089 and 39-187. Please advise when you are able to do so. Thank you. Have a great Monday! Be well. Alan.

Thank you for the extra pictures. I agree, you could have either our 39-089 or 39-187, but I can't tell from this photo. The angle of this photo is too low for me to make out the shape of the gear arm, which is the major difference. The 39-089 has a "Z" shaped gear arm while the 39-187 has more of a "W" shaped gear arm.
