Frequently Asked Questions
Q: What is the difference between part numbers 37558, 37558R, and 37558R.S?
A: The 37558R.S is a current revised variant that supersedes both the legacy 37558 and 37558R part numbers. It is the recommended replacement for those older sprockets and is fully compatible with the same range of Genie belt-drive openers.
Q: Where does the 37558R.S sprocket assembly mount and what does it do?
A: The sprocket assembly mounts on the drive shaft at the top of the motor head unit. It transfers rotational power from the motor to the drive belt by gripping the belt with its teeth, keeping the belt on track during door operation.
Q: Is any special preparation required before installing this sprocket assembly?
A: Yes. Before beginning installation, the opener unit must be removed from its mounting hardware and the garage door must be disconnected and left in the closed position. Installation involves 2-1/4 inch screws.
Q: How do I know if my belt drive sprocket needs to be replaced?
A: Symptoms of a worn or failed belt drive sprocket include the drive belt slipping or jumping off track, unusual grinding or skipping noises during operation, the door failing to move despite the motor running, or visible wear or broken teeth on the sprocket itself.
Q: Is the 37558R.S compatible with all belt-drive garage door openers?
A: The 37558R.S is designed specifically for Genie and Overhead Door belt-drive opener models listed in the compatibility data. It is not a universal sprocket and should only be used as a direct replacement in the confirmed compatible models.
