The Honda 91204-ZG3-003 Sealing Plug (47MM) is a genuine OEM component designed for GD320 and GD410 horizontal shaft diesel engines. Sourced directly from Honda, this plug delivers the exact fit and dimensions Honda specifies for these engines. Confirm your engine's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and more than one production range may share this model designation.
Key Features
- Genuine Honda OEM — manufactured to Honda's exact specifications for the GD320 and GD410 diesel engines, ensuring the correct 47MM diameter and sealing performance every time.
- Exact-Dimension Sealing — the 47MM size is a critical specification; this plug seats precisely to prevent fluid loss or contamination ingress in the application Honda designed it for.
- Diesel Engine Application — built specifically for GD-series horizontal shaft diesel engines; not interchangeable with petrol-engine variants of similar plugs.
- Serial Range Awareness — Honda updates part numbers at production serial breaks, so verify your engine's serial number against the compatibility table to confirm this is the correct plug for your unit.
A sealing plug closes an opening in the engine casting — such as an oil gallery, access bore, or housing port — that must remain sealed during normal operation. Without a properly seated plug of the correct diameter, the engine is exposed to fluid leakage or the entry of contaminants, either of which can lead to accelerated internal wear or oil loss. On GD-series diesel engines, maintaining these sealed passages is essential to consistent lubrication pressure and long service life.
