The Honda 91002-ZG4-801 Bearing An is a genuine OEM component designed for a wide range of Honda horizontal shaft engines, vertical shaft engines, generators, and tractors, including the GX610, GX620, GX630, GX640, GX660, GX670, GX690, GX700, GX800, GXV610, GXV620, GXV630, GXV660, GXV670, GXV690, GD320 diesel engines, EB10000 and EB11000 generators, and the H4518 and H5518 tractors. As a direct Honda OEM part, this Bearing An is manufactured to the same specification as the original, ensuring proper fit within each application it covers. Honda supersedes parts across serial breaks, so confirm your machine's serial number against the fitment table before ordering.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this Bearing A meets the original design tolerances that govern load handling and rotational smoothness in each covered application.
- Broad Compatibility — listed for Honda horizontal shaft engines including the GX610, GX630, GX690, GX800, and GD320; vertical shaft engines including the GXV610, GXV630, and GXV690; EB10000 and EB11000 generators; and H4518 and H5518 tractors.
- Direct OEM Replacement — this Bearing A drops in as a like-for-like replacement, with no rework or adaptation needed to fit the original mounting position.
- Serial Number Verification Recommended — Honda revises parts at defined serial breaks; cross-check your unit's serial number with the fitment table to confirm part number 91002-ZG4-801 is correct for your specific build.
- Restore Smooth Operation — a worn or failed bearing introduces friction, vibration, and accelerated wear on adjacent rotating components; replacing it with this OEM part restores normal operation and protects the surrounding assembly.
A bearing reduces friction between rotating and stationary components by providing a smooth rolling interface that supports shaft loads during operation. In engines, generators, and tractors, bearings carry both radial and thrust loads generated by rotating shafts, keeping alignment consistent and preventing metal-to-metal contact that would cause heat and rapid wear. When a bearing begins to fail, the symptoms typically include unusual noise, vibration, or play in the shaft — left unaddressed, bearing failure can cause significant secondary damage to the components it supports.
