The Honda 91203-750-003 Oil Seal (12X18X4) is a genuine OEM replacement designed for the HT3810, HT3813, and HT4213 lawn tractors. As a factory-sourced component, this seal is manufactured to the exact dimensions Honda specifies, ensuring it fits and functions exactly as the original. Confirm your tractor's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and the correct seal depends on your specific production range.
Key Features
- Genuine OEM Sealing Integrity — sourced directly from Honda, this seal meets the dimensional tolerances needed to prevent oil from migrating past the shaft, protecting internal components from contamination and oil loss.
- Exact-Dimension Replacement — the 12X18X4 sizing matches the original Honda specification, allowing this part to seat correctly without modification.
- Confirmed Fitment — listed for HT3810, HT3813, and HT4213 lawn tractors; always verify your serial number against the compatibility table to confirm this is the correct seal for your unit.
- Leak Prevention — a worn or failed oil seal allows oil to weep past the shaft, leading to low oil levels and potential drivetrain damage; replacing it promptly keeps the tractor operating as intended.
An oil seal creates a dynamic barrier around a rotating shaft, preventing oil from escaping the housing while keeping dirt and moisture out. In the HT-series lawn tractors, a failed oil seal results in visible oil leakage, dropping oil levels, and — if left unchecked — internal wear from oil starvation or contamination. Replacing the seal with a genuine Honda part restores the original sealing performance and protects the components it serves.
