The first thing you do with a window regulator is mark the positions of the
hooks on the counter balance spring and remove it. Wind the regulator up as
far as you can to do this. The rivet(s) will have to have the peened side
ground down and then driven out or pressed out. One way to assemble this is to
reuse the original rivet and weld it to the new gear fan( this is if you can't
get new rivets as most of these are shoulder rivets). Lube all pivot points
and especially the housing that holds the crank. There is a clutch spring
inside this that needs lube to work properly. Motorcycle chain lube works
great
here. Also lube the counter balance spring with white grease and reinstall
last. HTH Been a long time since I have had one of these apart.
