The Honda 91201-ZJ1-841 Oil Seal (38X58X9) is a genuine OEM component designed for GX610, GX620, and GX670 horizontal shaft engines, GXV610, GXV620, and GXV670 vertical shaft engines, and EB11000 generators. As a direct Honda OEM part, this oil seal is manufactured to the exact dimensional and material specifications Honda requires for a leak-free fit in these applications. Because Honda supersedes parts at serial-number breaks, confirm the part number 91201-ZJ1-841 against the fitment table using your machine's serial number before ordering.
Key Features
- Genuine OEM Sealing Integrity — manufactured by Honda to exact dimensional tolerances for this 38 x 58 x 9 mm envelope, ensuring proper shaft contact and oil retention rather than the seepage a worn or out-of-spec seal allows
- Broad Engine and Generator Coverage — listed for GX610, GX620, GX670, GXV610, GXV620, GXV670 engines and the EB11000 generator; verify your serial number against the fitment table to confirm the correct application
- Direct OEM Replacement — matches the original seal's dimensions and lip profile, allowing straightforward installation without modification to the housing or shaft
- Protects Against Oil Loss — a functioning oil seal keeps crankcase oil where it belongs; a degraded seal leads to external leakage, oil starvation risk, and contamination of surrounding components
An oil seal prevents engine or generator oil from escaping around a rotating shaft — typically the crankshaft or a gear shaft — where it exits the engine case or housing. It does this through a precision-formed lip that maintains constant contact with the shaft surface, blocking oil while allowing the shaft to spin freely. When an oil seal deteriorates, hardens, or becomes damaged, it loses that contact and allows oil to seep out, which can lead to low oil levels, external contamination, and accelerated wear if left unaddressed.
