The Honda 90547-750-000 Mainshaft Washer G (17.2X28X3.55) is a genuine OEM component designed for HT3810, HT3813, and HT4213 lawn tractors. As a direct OEM replacement, this washer is sourced from Honda to meet the exact dimensional requirements of the mainshaft assembly in these machines. Confirm your tractor's serial number against the fitment table before ordering, as Honda issues part supersessions at specific serial breaks.
Key Features
- Genuine OEM Dimensional Accuracy — sourced directly from Honda to the 17.2 x 28 x 3.55 mm specification, ensuring the washer seats and functions correctly on the mainshaft.
- Direct OEM Replacement — this washer drops into position on the mainshaft without any modification, restoring proper shaft retention and spacing.
- Fits HT3810, HT3813, and HT4213 Lawn Tractors — verify your serial number against the compatibility table, as Honda supersedes drivetrain components at defined serial ranges.
The Mainshaft Washer G is a precision-dimensioned flat washer that sits on the mainshaft within the drivetrain of Honda's HT-series lawn tractors. It provides the correct axial spacing and bearing surface needed to keep shaft-mounted components properly positioned under load. When this washer is worn, damaged, or missing, components on the mainshaft can shift out of position, leading to drivetrain noise, uneven wear on adjacent parts, or loss of drive engagement — making correct replacement essential to keeping the tractor operating as intended.
