The Genie 36605A.S Belt Drive Pulley Assembly is a genuine OEM replacement pulley for select Genie belt‑drive garage door openers. Positioned at the opener head, this assembly engages and guides the belt to transfer motor power smoothly to the rail, helping maintain quiet, reliable door travel. It’s used to replace a worn, cracked, or noisy pulley and to restore proper belt tracking and drive performance on compatible Genie belt‑drive systems.
This is a mechanical component with no electrical connections and is intended for residential Genie openers that specifically list 36605A.S in the unit’s parts manual or exploded parts diagram. It is not a universal substitute; verify compatibility by opener model and part number before ordering. For installation, disconnect power to the opener, place the door in the down position, relieve belt tension, swap the pulley assembly, then re‑align and re‑tension the belt per Genie instructions. After installation, test safety reversing features and recheck travel limits if needed.
