The Honda 91202-GB4-692 Oil Seal (18.9X28X5) is a genuine OEM component designed for GXV57 vertical shaft engines. As a direct Honda OEM part, it is manufactured to the same specification as the original seal installed at the factory, ensuring the correct dimensional fit for this application. Confirm your engine's serial number against the fitment table before ordering, as Honda supersedes seals at production breaks and the listed dimensions — 18.9 x 28 x 5 mm — must match your engine's housing bore exactly.
Key Features
- OEM Sealing Integrity — manufactured to Honda's original dimensional specification, delivering the lip geometry and interference fit needed to prevent oil migration past the shaft
- Exact Dimensional Match — the 18.9 x 28 x 5 sizing is specific to this application; always verify the size against your engine before installation
- GXV57 Fitment — sourced directly from Honda and listed for GXV57 vertical shaft engines
- Serial Number Verification Recommended — Honda updates seals at production changes, so cross-check your engine serial number against the compatibility table to confirm this is the correct supersession for your unit
An oil seal prevents engine oil from escaping along a rotating shaft by maintaining a continuous, pressurized lip contact against the shaft's surface. In a vertical shaft engine like the GXV57, a correctly seated seal keeps oil contained within the crankcase, maintaining proper lubrication levels and preventing external contamination. When an oil seal wears, hardens, or is displaced, oil loss occurs at the shaft exit point — leading to low oil levels, potential engine damage, and visible leaking at the base of the engine.
