The Honda 91002-ZG3-003 Special Ball Bearing A (6204) is a genuine OEM replacement designed for GD320 and GD410 horizontal shaft diesel engines. As a factory-sourced component, this bearing is manufactured to Honda's exact tolerances, ensuring the dimensional accuracy and load ratings the GD-series diesel demands. Sourced directly through Honda's OEM parts network, this is the same bearing that ships in new GD320 and GD410 engines — making it the straightforward choice when a bearing replacement is due.
Key Features
- Genuine OEM Bearing Specification — manufactured to the exact dimensional and load tolerances Honda specifies for the GD-series diesel, ensuring the bearing seats and performs as intended in the original application
- 6204-Series Ball Bearing — the (6204) designation identifies this as a specific bearing size; confirm the bearing reference on your engine before ordering to ensure you have the correct unit
- Direct-Fit for GD320 and GD410 Diesel Engines — validated for Honda's horizontal shaft diesel lineup; check your engine's serial number against the fitment table to confirm compatibility with your specific build
- Smooth Rotation and Load Support — a worn or failed bearing introduces vibration, noise, and drag into rotating assemblies; replacing it with the correct OEM part restores smooth operation and protects adjacent components
A ball bearing supports and locates a rotating shaft, allowing it to spin freely while managing both radial and axial loads generated during engine operation. In Honda's GD-series horizontal shaft diesel engines, precision bearings are critical to maintaining correct shaft alignment throughout the powertrain. When a bearing wears, it develops play or roughness that can manifest as abnormal noise, vibration, or heat — and left unaddressed, a failed bearing can cause accelerating damage to the shaft and surrounding housings. Replacing the Special Ball Bearing A (6204) with the correct genuine OEM part restores proper shaft support and keeps the engine running within its designed operating parameters.
