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.
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.
