Crank shaft came apart or out. Think I need to replace unit or operator. I have more pictures installed if needed. No name on window or parts. The operator is stamped USA and UK PAT
The # on it is 213539. Thanks
Michael

Hello,
Your crank resembles the 39-312 at first glance. Review the specifications below to confirm they match up to yours. We also offer the 39-512 track and 39-114L handle for this assembly. Thanks for posting!
