The Honda 90545-750-000 Mainshaft Washer E (17.2X28X3.45) is a genuine OEM component designed for HT3810, HT3813, and HT4213 lawn tractors. As a direct Honda replacement, this washer is sourced and manufactured to the exact specifications of the original part. Confirm the part number 90545-750-000 against your tractor's serial number and parts diagram before ordering, as Honda supersedes components at serial breaks and fitment can vary within a model line.
Key Features
- Genuine OEM Sourcing — supplied directly from Honda, ensuring this washer matches the original dimensions (17.2 x 28 x 3.45 mm) specified for the mainshaft application
- Exact Dimensional Match — correct thickness and inner/outer diameter are critical in a mainshaft application; an incorrectly sized washer affects clearance and component seating
- Fits HT-Series Lawn Tractors — listed for the HT3810, HT3813, and HT4213; verify your serial number against the fitment table to confirm the correct variant for your unit
- Serial-Range Verification Recommended — Honda updates drivetrain components across production runs; always cross-check your tractor's serial number before ordering
A mainshaft washer serves as a precision spacer and load-bearing surface within the tractor's drivetrain, controlling axial clearance and preventing metal-to-metal contact between rotating components on the mainshaft. Maintaining the correct washer thickness ensures that shaft-mounted components seat properly and that drivetrain loads are distributed as designed. A worn, missing, or incorrectly sized washer can lead to excessive play on the shaft, accelerated wear of adjacent components, and loss of smooth power transmission through the drivetrain.
