The Honda 28450-Z7Y-003 Starter Pulley is a genuine OEM component designed for the GXV57 vertical shaft engine. As a direct Honda OEM part, it is manufactured to the same specification as the original, ensuring a proper fit within the recoil starter assembly. Confirm your engine's serial number against the fitment table before ordering to make sure part number 28450-Z7Y-003 is the correct match for your unit.
Key Features
- Genuine Honda OEM — manufactured by Honda to original specification, so the rope groove geometry and pawl engagement are exactly as designed for the GXV57 recoil starter.
- Correct Recoil Engagement — the pulley's pawl interface is what transfers the pull-cord force to the engine's flywheel; a worn or damaged pulley causes erratic or failed engagement at startup.
- GXV57 Fitment — confirmed for the GXV57 vertical shaft engine; check your serial number against the fitment table to verify this is the right pulley for your serial range.
The starter pulley sits at the heart of the recoil starter assembly. When the operator pulls the starter rope, the rope wraps around the pulley's groove and spins it, extending the pawls outward to engage the engine's flywheel and crank the engine over. Once the engine fires, the flywheel outruns the pulley and the pawls retract, disengaging cleanly. A pulley that is cracked, worn, or has damaged pawl seats will cause hard starting, rope slippage, or a starter that fails to engage the flywheel at all — making this a straightforward but essential service item.
