Technician Note
Pulley wear is often tied to rail alignment, chain condition, and trolley movement. If a replacement pulley wears quickly, check the surrounding drive components instead of assuming the new part failed.

- Match the parts diagram to 41B4569 or 041B4569
- Inspect the chain, rail, trolley, and brackets for related wear
- Confirm the pulley profile matches the original part
- Do not substitute a similar-looking pulley from a different rail system
Professional Advisory
Disconnect power before servicing opener drive parts. If the door is heavy, binding, or unsafe to move manually, have the door and opener inspected by a qualified garage door technician before replacing rail components.
