The Honda 91201-Z6L-003 Oil Seal (38X58X9) is a genuine OEM component designed for Honda GX630, GX660, GX690, GX700, and GX800 horizontal shaft engines, GXV630, GXV660, and GXV690 vertical shaft engines, and EB10000 generators. As a direct OEM replacement, this seal is manufactured to Honda's exact dimensional specifications — the 38 x 58 x 9 mm sizing is precisely what the application demands, so fitment is determined by your machine's serial number and not by model alone. Always confirm part number 91201-Z6L-003 against your unit's serial number in the fitment table before ordering, as Honda supersedes seals at production breaks across this engine family.
Key Features
- Genuine Honda OEM Sealing — manufactured to the exact dimensional profile (38 x 58 x 9 mm) that Honda specifies, ensuring the correct interference fit and lip-contact pressure for a lasting oil-tight seal
- Broad Fitment Across Large-Displacement Honda Equipment — listed for GX630, GX660, GX690, GX700, and GX800 horizontal shaft engines; GXV630, GXV660, and GXV690 vertical shaft engines; and EB10000 generators — verify your serial number against the fitment table to confirm the correct application
- Exact-Dimension Replacement — the 38 x 58 x 9 mm sizing is specific to this seal position; using an undersized or oversized substitute risks premature leakage and oil loss
- Prevents Oil Loss at High-Load Operating Conditions — large-displacement Honda engines operate under sustained load in commercial and industrial settings; a failed seal allows oil to escape at the shaft, accelerating bearing wear and risking engine damage
An oil seal is a precision lip-type seal that prevents engine or crankcase oil from escaping along a rotating shaft. It holds a spring-loaded rubber lip in continuous contact with the shaft surface, blocking oil from passing outward while keeping contaminants from entering the crankcase. When an oil seal wears, hardens, or is damaged, it loses its lip-contact pressure and allows oil to leak past the shaft — a loss that, if left unchecked, drops the oil level and starves bearings and other internal components of lubrication. Replacing a leaking seal promptly with the correct OEM part restores the oil-tight boundary and protects the engine or generator's internal components from the damage that follows sustained oil loss.
