The Honda 90452-708-000 Washer (12MM) is a genuine OEM replacement designed for a wide range of Honda outdoor power equipment, including F28 tillers, GB4038 and GB4500 lawn tractors, GC3000 and GC3800 riding mowers, and HR194, HR21, HR214, HRA214, HRM21, and HRS21 lawn mowers. As a direct Honda OEM part, this washer is manufactured to the exact dimensions specified for these applications. Because Honda supersedes parts across serial number ranges, confirm your machine's serial number against the fitment table before ordering to make sure part number 90452-708-000 is correct for your unit.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this washer meets the exact dimensional specification Honda requires for the applications it covers.
- Broad Fitment — listed for Honda F28 tillers, GB4038 and GB4500 lawn tractors, GC3000 and GC3800 riding mowers, and multiple HR-series lawn mowers including the HR194, HR21, HR214, HRA214, HRM21, and HRS21.
- Serial Number Verification Recommended — Honda updates part fitment at production breakpoints, so always cross-check your machine's serial number against the compatibility table to confirm this is the correct washer for your unit.
A washer like this 12MM component distributes the clamping load of a fastener across a broader surface area, protecting the material beneath and helping the fastener maintain consistent tension over time. In outdoor power equipment — where vibration, weather exposure, and seasonal use cycles place repeated stress on hardware — using the correct OEM-specified washer ensures the fastener assembly performs as Honda designed it. Installing an incorrectly sized washer can result in uneven clamping, fastener loosening, or damage to the mating surface.
