Window crank broke on Sun Casement window. Will crank out but not back in. Probably need the whole crank assembly. Window was made in 1987.

It looks like your worm gear stripped out, so you'll definitely need a new operator. Yours looks like an older version of our 39-028E, but review the dimensions we show for this product to confirm.

We also sell the 39-027E for the opposite side.
