The Honda 55109-GAA-000 Oil Hose Clamp is a genuine OEM replacement designed for GX630, GX660, and GX690 horizontal shaft engines. As an authentic Honda part, it is built to the same specification as the original installed at the factory, ensuring a secure, properly dimensioned fit on the oil hose it retains. This clamp is compatible with all three engines in Honda's large-displacement GX series — confirm your engine's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks within a model run.
Key Features
- Genuine OEM Construction — sourced directly from Honda, this clamp matches the original in every dimension, so the oil hose seats and holds exactly as engineered.
- Correct Retention Force — a clamp that has lost its grip allows oil hose connections to weep or separate; this OEM replacement restores the clamping load Honda specified for these high-displacement engines.
- GX630, GX660, and GX690 Fitment — designed specifically for Honda's large-frame horizontal shaft engine family; verify part number 55109-GAA-000 and your serial number against the fitment table to confirm applicability to your unit.
- Serial Number Verification Recommended — Honda issues parts updates at defined serial breaks, so checking your engine's serial number ensures this is the correct clamp revision for your machine.
An oil hose clamp secures the flexible hose that carries engine oil between components in the lubrication circuit, keeping the connection tight under the heat and pressure cycling that occurs during normal engine operation. When a clamp weakens, fatigues, or loses its grip, the hose can work loose and allow oil to leak — starving critical engine components of lubrication and leading to accelerated wear or seizure. Replacing a compromised clamp promptly with the correct OEM part protects the long-term health of the engine and the equipment it powers.
