Awning window operator with worn gears

Hello! Sounds like yo need a new operator. I recommend our 39-239B. I believe this is a newer version of your older part. The major difference is that the base cover is now removable and sold separately; we have it under the 39-451 set.

We also sell the 39-536 slide but you can just reuse the originals as long as they're in good condition.
