The Honda 28450-Z4H-003 Starter Pulley (TEC) is a genuine OEM replacement designed for GX120 horizontal shaft engines. As a direct Honda OEM part, it is manufactured to the same specifications as the original, ensuring a correct fit within the recoil starter assembly. Confirm your engine's serial number against the fitment table before ordering.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this pulley matches the original part in geometry and pawl engagement, so the recoil starter operates as intended from day one.
- Correct Variant for TEC Applications — the (TEC) designation identifies a specific pulley variant; matching this qualifier to your engine's original part number is essential before purchase.
- GX120 Fitment — built for GX120 horizontal shaft engines; check your serial number against the compatibility table to confirm this is the right pulley for your production range.
- Rope Groove Integrity — a worn or cracked starter pulley causes the recoil rope to fray, slip, or snap; replacing it with this OEM unit restores smooth, consistent pull-starts.
The starter pulley is the rope-winding spool at the heart of the recoil starter. When the operator pulls the starter handle, the rope unwinds from the pulley's groove, spinning the pulley and engaging the pawls that turn the engine crankshaft. Once released, the recoil spring returns the pulley to its resting position and retracts the rope. A damaged or worn pulley prevents the rope from winding evenly and can make the engine difficult or impossible to start by hand.
