Looking for this part which is inserted in the crank mechanism of a semco dual arm window crank. Also I don't know if there is supposed to be a pin which keep this part from unscrewing when the crank is turned.

I need the part shown in the attached picture. The bronze insert will not stay in place because the housing threads have stripped, and when you get the handle almost closed the rotating shaft pops out. The operator has four mounting holes.

i want to find a new worm gear and handle for this bathroom window. Is that possible or do I need to replace the operator? Thank you!

Window was cranked open to max and then when tried to close the handle came out the the casing. The inside is stripped so it looks like I need a new unit. Only marking on it is Somco.

Couldn't find any numbers on these anywhere. Any help would be appreciated.
