The Honda 90503-750-881 Plain Washer (5/16) is a genuine OEM replacement designed for the HT3810 lawn tractor. As a factory-original component, this washer is sourced directly through Honda's parts network to ensure it matches the original specification used in production. Confirm your unit's serial number against the fitment table below before ordering, as Honda periodically supersedes hardware across serial ranges.
Key Features
- Genuine OEM Sourcing — supplied directly through Honda's parts network, matching the exact specification used on the HT3810 at the factory
- Correct 5/16" Size — the (5/16) designation identifies this specific variant; verify it matches the original washer on your machine before ordering
- HT3810 Fitment — listed for the Honda HT3810 lawn tractor; check your serial number against the compatibility table to confirm applicability to your unit
A plain washer distributes the clamping load of a fastener — such as a bolt or nut — across a broader surface area, protecting the material beneath and helping the fastener maintain consistent holding force. On a lawn tractor like the HT3810, plain washers appear throughout the machine wherever fasteners need load spreading or a smooth bearing surface. When a washer is missing, deformed, or the wrong size, fasteners can loosen over time or damage the surfaces they bear against, leading to component movement or wear that compounds with use.
