Key Features
- Genuine OEM Specification — manufactured to Honda's exact dimensional tolerances for the 10 x 40 mm size, so it seats correctly without shimming or makeshift substitution
- Direct Replacement — sourced directly from Honda as an OEM part, part number 90504-750-A00 drops straight in without modification
- Confirmed Fitment — listed for HT3810, HT3813, and HT4213 lawn tractors; verify your serial number against the fitment table to confirm the correct application for your unit
A washer of this size serves as a load-distributing spacer or retaining element within the tractor's assembly, spreading clamping force evenly across the fastened components to prevent damage and maintain proper tension. Using the correctly sized washer — in this case the 10 x 40 mm OEM piece — ensures that fasteners torque down properly and that mating surfaces are not distorted under load. A missing or undersized washer can lead to fastener loosening, uneven clamping, and accelerated wear of the components it supports.
