The Honda 90503-SA0-000 Plain Washer (9MM) is a genuine OEM replacement built for H3011 and H3013 riding mowers and H4013, H4514, and H4518 lawn tractors. As a direct OEM component, this washer is manufactured to Honda's original specifications, ensuring it seats and functions exactly as the original part did. Verify your machine's serial number against the fitment table before ordering, as Honda supersedes hardware at serial breaks across these models. When you need an exact-fit 9MM washer to keep your Honda riding mower or lawn tractor running right, part number 90503-SA0-000 is the correct OEM choice.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, so the 9MM bore and overall dimensions match the original washer exactly, with no guesswork on sizing
- Broad Riding Mower and Lawn Tractor Fitment — listed for H3011, H3013, H4013, H4514, and H4518 models; confirm your serial number against the compatibility table to ensure the correct application
- Direct Drop-In Replacement — replaces the original washer without modification, keeping service time short on routine maintenance and repair work
A plain washer distributes the clamping load of a fastener across a wider surface area, preventing the bolt head or nut from pulling through or damaging the material it bears against. On Honda riding mowers and lawn tractors, washers like this one appear throughout the machine wherever consistent clamping force and proper fastener seating are required. A worn, deformed, or missing washer can allow a fastener to work loose over time, undermining the integrity of the assembly it secures.
