The Honda 91201-ZG3-003 Oil Seal (40X67X10) is a genuine OEM replacement designed for the GD410 horizontal shaft diesel engine. As a direct Honda OEM part, this seal is manufactured to the same specifications as the original, ensuring proper fit and function within the GD410's lubrication system. If your engine is showing signs of oil leakage around a shaft exit point, this seal is the correct OEM remedy — confirm fitment against your engine's serial number using the fitment table before ordering.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this is the same seal that left the factory with your GD410 diesel engine, not an approximation of it.
- Correct Dimensional Spec — the 40X67X10 designation identifies the seal's inner diameter, outer diameter, and width; matching this exactly is critical for a leak-free installation.
- GD410 Diesel Fitment — engineered specifically for the GD410 horizontal shaft diesel engine; verify your serial number against the fitment table, as Honda supersedes seals at production breaks.
- Leak Prevention — a degraded or damaged oil seal allows engine oil to escape past a rotating shaft, leading to oil loss, contamination of adjacent components, and potential engine damage if left unaddressed.
An oil seal keeps engine oil contained within the crankcase by forming a dynamic, low-friction barrier around a rotating shaft — typically the crankshaft output shaft or camshaft. In the GD410 diesel engine, maintaining this seal is essential for sustaining proper oil pressure and preventing oil from migrating to areas where it can cause belt, seal, or gasket deterioration. When an oil seal hardens, cracks, or wears, it loses its ability to maintain that barrier, and oil weeping or streaming past the shaft is the result — a condition that demands prompt replacement to protect the engine's long-term integrity.
