I want to replace the crank in a 1977 bay jalousie window.   I don't want to
do a total rebuild, I just want to have the cranking mechanism  work.
Does anyone have any helpful hints?    I have purchased a new crank.   Most
of the videos online are for a total rebuild, and they take the entire
window apart.   Is there a simpler way just to replace the crank?

Thanks!
