LiftMaster K17-G0475 6 x 5/8 Replacement Pulley
The K17-G0475 pulley is a factory replacement drive pulley used in select LiftMaster commercial swing gate operator systems. The 6 inch diameter and 5/8 inch bore are important details because they control belt fit, shaft fit, and drive alignment. A pulley with the wrong bore or diameter can create speed, tension, and belt wear problems.
This part is commonly used in SW420GL and SW470GL service work. If a gate is noisy, slipping, or producing belt dust, the pulley should be checked along with the belt, motor mounting, gear reducer alignment, set screws, and shaft condition. The part should be matched by model and diagram, not by appearance alone.

Technician Note
A worn pulley can damage a good belt quickly. After replacement, run the operator through cycles with the cover open only when safe to confirm the belt is tracking straight and not walking off the pulley.
Before Ordering

- Match the 6 inch x 5/8 inch pulley size
- Verify K17-G0475, G17G0475, or 17-G0475 in the parts diagram
- Inspect the belt, shaft, set screws, and motor alignment
- Do not replace a 7 inch pulley with this 6 inch pulley
Professional Advisory
Disconnect power before servicing the operator. For high-voltage wiring, three-phase equipment, moving gate hardware, or uncertain diagnosis, use a qualified gate technician. Do not bypass entrapment protection or safety devices to make an operator run.
