The Genie 601332.0004.S is a genuine OEM service replacement replacement sprocket designed for Genie commercial door operators using #25 chain drive. This 18-tooth #25 chain sprocket with 3/8 inch bore is manufactured to Genie factory specifications, ensuring accurate chain engagement, reliable torque transfer, and minimal downtime during maintenance. Constructed from Steel - standard sprocket construction, the 601332.0004.S maintains dimensional accuracy for consistent chain tracking. Always verify the chain size, tooth count, and bore diameter match your operator's drive assembly before installation. Using genuine Genie service replacement parts preserves drive train integrity and extends the service life of the complete operator.
A: The .0004.S has 18 teeth versus 14 teeth on the .0001.S. Both share identical bore (3/8 inch) and pitch (1/4 inch, #25 chain). The 18-tooth version provides a different drive ratio - lower mechanical advantage but higher output speed when used as the drive sprocket.
A: A higher tooth count on the drive sprocket increases output speed relative to a lower tooth count drive sprocket, assuming the driven sprocket remains constant. Verify OEM tooth count before substituting.
A: Both use #25 chain (1/4 inch pitch) with a 3/8 inch bore, so the chain itself is interchangeable between the two variants. Only the drive ratio changes with the tooth count difference.
