Hi there! You assumed correctly! It sounds like your worm gear is stripped. That part can't be repaired or replaced which means you'll need a new operator. Start by taking a look at our 39-258 and 39-259 operators. The style of link arm and offset hole pattern on the bottom tab is similar to yours but you'll need to compare our dimensions to your old hardware to see if this matches up. |
