Searching for replacement for Marvin 3248 casement window operator

Question

?Do you have a replacement for a Marvin 3248 casement window operator crank assembly? I purchased the window in July 1989 and the gears are now stripped. It opens but doesn't close. The assembly arms are stamped "Truth."

Hi there!

My recommendation would be the 39-031 & 39-032 or 39-155 & 39-156 operators. Look over the dimensions, paying close attention to the link arm, to see if one matches what you're looking for. We also sell the 39-114L handle and 39-107 cover in case you needed that.
