The Honda 91302-Z6M-003 Oil Pump O-Ring is a genuine OEM component designed for GXV630, GXV660, and GXV690 vertical shaft engines. As a direct Honda OEM part, it is manufactured to the exact dimensions required to maintain a proper seal within the oil pump circuit on these engines. This O-Ring is the correct replacement for GXV630, GXV660, and GXV690 engines — confirm your engine's serial number against the fitment table before ordering, as Honda revises part fitment at specific serial breaks.
Key Features
- Exact-Dimension Sealing — manufactured to Honda's precise profile so the O-Ring seats fully in its groove and holds the oil pump circuit sealed without leakage
- Genuine Honda OEM Part — sourced directly from Honda, ensuring the correct material grade and cross-section for part number 91302-Z6M-003
- Fits GXV630, GXV660, and GXV690 Engines — designed specifically for this family of large-displacement vertical shaft engines; check your serial number against the fitment table to confirm the correct listing for your unit
- Protects Engine Lubrication — a compromised oil pump O-Ring allows pressure loss or external leakage; replacing it promptly keeps the lubrication system operating as intended and protects internal engine components from oil starvation
The oil pump O-Ring forms a pressure-tight seal at the oil pump on the engine's lubrication system. It prevents engine oil from escaping past the pump body, maintaining the flow and pressure needed to deliver lubrication to the engine's moving parts. When this O-Ring deteriorates, hardens, or takes a set, the seal breaks down — resulting in oil leaks, a drop in oil pressure, or both — which can lead to accelerated wear on critical internal components if left unaddressed.
