I have two windows (images 5201 and 5204) where the drive pinion has come loose. Is that something I can fix or do I need all new crank assemblies. Both cranks have 20544 stamped on them, but one window only uses the long arm, where the other uses both arms. The long arm appear to be 9" long.
I have a third window where the gears are stripped (image 5208). It appears to be identical, model #20544 and ~9", but opens the window from the opposite side. Is there a left and right handed crank?
Thanks,
GeorgeĀ
