The Honda 90503-751-000 Washer (17.3X25) is a genuine OEM replacement designed for CD3009, CD3811, H3011, and H3013 riding mowers and the HR17 lawn mower. As a direct Honda OEM component, this washer is manufactured to the exact dimensions Honda specifies for these machines, ensuring a proper fit without guesswork. Verify your model and serial number against the fitment table before ordering to confirm this is the correct washer for your unit.
Key Features
- Genuine Honda OEM — sourced directly from Honda, so the 17.3 x 25 mm dimensions match the original specification exactly.
- Correct Sizing Matters — washers in this application are sized to distribute load correctly; an incorrect washer can lead to fastener loosening or uneven clamping over time.
- Broad Model Coverage — listed for CD3009, CD3811, H3011, H3013, and HR17 machines; confirm your serial number against the fitment table to ensure this is the right part for your unit.
A washer of this type distributes the clamping force of a fastener across a wider surface area, preventing the fastener head or nut from pulling through or damaging the mating surface. On riding mowers and walk-behind mowers, correctly seated washers keep assemblies torqued securely through the vibration and load cycles these machines encounter during normal operation. When a washer is missing, deformed, or the wrong size, fasteners can work loose and cause premature wear or component failure at that joint.
