The Honda 28474-Z1B-D10 Reel Starter Cover is a genuine OEM replacement designed for a wide range of Honda equipment, including EG650, EM650, and EX650 generators, the G100 horizontal shaft engine, the WB15 water pump, the HR173 lawn mower, the F210 tiller, and the HP250 power carrier. As a direct Honda OEM component, this cover is manufactured to the same specifications as the original part it replaces, ensuring a proper fit without modification. Confirm the part number 28474-Z1B-D10 against your machine's serial number before ordering, as Honda supersedes parts at production breaks and fitment can vary within a model line.
Key Features
- Genuine Honda OEM Construction — manufactured by Honda to match original dimensions and geometry, so the recoil starter assembly seats and functions exactly as it did from the factory.
- Broad Multi-Equipment Compatibility — covers generators including the EG650, EM650, EX650, and EX1000; the G100 engine; the WB15 water pump; the HR173 lawn mower; the F210 tiller; and the HP250 power carrier.
- Verify by Serial Number — Honda updates part numbers at production breaks, so cross-check part number 28474-Z1B-D10 against your unit's serial number using the fitment table to confirm this is the correct cover for your build.
- Protects the Recoil Mechanism — shields the internal reel and pawl assembly from debris, moisture, and impact, keeping the starter engagement smooth and consistent over time.
The reel starter cover is the outer housing that encloses the recoil starter assembly — the spring-loaded rope reel and pawl mechanism a user pulls to crank the engine. It keeps dirt, water, and physical damage away from the internal components, which are precision-fit and sensitive to contamination. When the cover cracks, breaks, or goes missing, the recoil mechanism is left exposed to the elements, accelerating wear on the rope, spring, and pawls and ultimately leading to hard-starting or a starter that will not engage at all. Replacing a damaged cover promptly with the correct OEM part restores full protection and keeps the starting system operating as designed.
