Technician Note
On a screw drive opener, always inspect the rail, trolley, coupler, and drive screw condition. A new sprocket kit will not solve a binding rail or out-of-balance garage door.
Before Ordering
- Confirm the opener is a screw drive or low-profile screw drive model.
- Match 041A4836 or 41A4836 in the parts diagram.
- Inspect the rail and trolley for wear before replacing the sprocket.
- Check the door balance so the opener is not overloaded.
- Do not use this kit for chain drive or belt drive opener repairs.
Professional Advisory
If the opener is grinding, binding, or running without moving the door, stop operation until the drive system is inspected. Continued use can damage additional rail and motor components.
