The Honda 28451-ZG0-004 Starter Pulley is a genuine OEM component designed for EG650 generators and WB15 water pumps. As a direct Honda OEM part, it is manufactured to the same specifications as the original and integrates with the existing recoil starter assembly without rework. Because Honda supersedes parts at serial breaks, confirm the part number 28451-ZG0-004 against your machine's serial number before ordering. This Starter Pulley is a straightforward service item that restores proper recoil starter function when the original becomes worn, cracked, or damaged.
Key Features
- Genuine OEM Rope Groove Integrity — manufactured by Honda to ensure the rope seats and winds evenly, maintaining consistent recoil tension across the pull stroke.
- Direct OEM Replacement — part number 28451-ZG0-004 replaces the original pulley on EG650 generators and WB15 water pumps, fitting the existing recoil starter housing without modification.
- Broad Equipment Coverage — fits EG650 generators and WB15 water pumps, including multiple serial ranges; verify your machine's serial number against the fitment table to confirm the correct pulley for your unit.
- Restored Starting Performance — a worn or broken starter pulley prevents the recoil rope from retracting and building the spring tension needed to crank the engine; replacing it restores a clean, reliable pull every time.
The starter pulley is the rope-winding hub at the heart of the recoil starter assembly. When the operator pulls the starter rope, it unwinds from the pulley, which rotates and transfers that motion through the starter pawls to crank the engine. A return spring then retracts the rope by rewinding it onto the pulley, resetting the starter for the next pull. When the pulley cracks, chips at the rope anchor, or wears unevenly, the rope may slip, fail to retract, or jam — leaving the engine unable to start until the pulley is replaced.
