The Honda 90534-750-000 Washer (8.5MM) is a genuine OEM replacement designed for the HT3810, HT3813, and HT4213 lawn tractors. As a direct Honda OEM part, it is manufactured to the same specifications as the original hardware installed at the factory. This washer is listed for all three HT-series tractors — confirm your tractor's serial number against the fitment table to ensure this is the correct variant for your machine.
Key Features
- Genuine Honda OEM Hardware — sourced directly from Honda's parts catalogue, ensuring this is the exact washer specified for these HT-series lawn tractors
- Correct 8.5MM Sizing — the 8.5MM designation identifies the specific bore size; verify your machine's requirements match before ordering, especially across multiple fitment variants
- HT-Series Fitment — listed for the HT3810, HT3813, and HT4213 lawn tractors; check your serial number against the compatibility table to confirm applicability to your unit
A washer like this one distributes the clamping load of a fastener across a wider surface area, protecting the surrounding material from damage and helping the fastener maintain consistent holding force over time. In a lawn tractor, where vibration and repeated stress cycles are part of normal operation, using the correct OEM-specified washer keeps assemblies properly torqued and reduces the chance of fastener loosening. Substituting an incorrect size can result in uneven load distribution or fastener movement, compromising the integrity of the connection.
