The Honda 90401-VK4-003 Washer (5MM) is a genuine OEM component designed for GX35 horizontal shaft engines. As a direct Honda OEM part, it is manufactured to the exact dimensions Honda specifies for this application, ensuring the correct fit the first time. This washer is listed for the GX35 engine — confirm your serial number against the fitment table to make sure part number 90401-VK4-003 is the right match for your specific unit.
Key Features
- Genuine OEM Spec — manufactured by Honda to the exact diameter and thickness required for the GX35, so clearances and clamping load remain within Honda's design intent
- Exact Dimensional Match — the 5MM sizing is specific to this application; substituting an incorrect washer can affect fastener tension and retention
- GX35 Fitment — listed for GX35 horizontal shaft engines; verify your engine's serial number against the fitment table before ordering
A washer of this size serves as a load-distributing interface between a fastener and the surface it clamps, spreading the bearing load over a wider area to protect the mating surface and maintain consistent clamping force. On a compact engine like the GX35, correct hardware dimensions are particularly important because component clearances are tight and undersized or oversized washers can allow fasteners to loosen over time. Using the wrong size washer risks insufficient retention or damage to the surrounding material, so matching the correct part number to your engine is essential.
