The Honda 91231-Z1V-003 Oil Seal (6X11X4) is a genuine OEM component designed for GXV160 vertical shaft engines and HRC216 lawn mowers. As an authentic Honda part, this seal is manufactured to the exact dimensions and material tolerances specified for these applications, ensuring a proper fit with no guesswork. Honda supersedes parts at serial breaks, so confirm your machine's serial number against the fitment table before ordering. This oil seal is a direct OEM replacement that restores the integrity of your engine's sealing system and gets your equipment back to work.
Key Features
- Genuine OEM Sealing Integrity — manufactured to Honda's exact dimensional specification for this 6×11×4 mm application, delivering the correct interference fit and lip geometry that an oil seal depends on to do its job.
- Direct OEM Replacement — this seal installs in place of the original with no alteration required, matching the bore, shaft, and depth dimensions of the factory position.
- Confirmed Fitment — listed for GXV160 vertical shaft engines and HRC216 lawn mowers; verify your unit's serial number against the compatibility table to confirm this is the correct seal for your serial range.
- Prevents Oil Loss — a worn or degraded oil seal allows engine oil to escape past the shaft, leading to low oil levels, contamination of surrounding components, and potential engine damage if left unaddressed.
An oil seal is a precision-fit ring that closes the gap between a rotating shaft and a stationary housing, keeping engine oil inside the crankcase while blocking dirt, debris, and moisture from entering. In GXV160 vertical shaft engines and HRC216 lawn mowers, the crankshaft spins continuously under load, and the oil seal maintains a dynamic barrier against that rotating surface. When the seal lip wears, hardens, or takes a set, oil weeps past it — signaled by oily residue around the crankshaft area — and the engine becomes vulnerable to oil starvation and accelerated wear.
