The Honda 90402-Z2E-000 Tank Mounting Washer is a genuine OEM component designed for GX440 horizontal shaft engines. As a Honda OEM part, it is manufactured to the exact specifications of the original, ensuring a correct fit without modification. This washer is listed for the GX440 — confirm your engine's serial number against the fitment table before ordering to make sure this is the right part for your unit. Having the correct washer in place keeps the tank mounting hardware properly seated and correctly torqued.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this washer matches the original part in dimensions and load-bearing profile, so hardware seats and clamps correctly first time.
- Exact Fit for GX440 Engines — catalogued specifically for the GX440 horizontal shaft engine; check your serial number against the fitment table to confirm applicability.
- Serial Number Matters — Honda supersedes hardware at production breaks, so verifying your engine's serial number before ordering ensures you receive the correct washer for your build.
A tank mounting washer distributes the clamping load of the mounting fastener across the tank bracket or mounting surface, preventing the hardware from pulling through or distorting the material it bears against. Without the correct washer in place, the mounting fastener can work loose over time or damage the surrounding surface, leading to an insecure fuel tank. Using the OEM-spec washer restores the proper clamping geometry and keeps the assembly stable under the vibration a running engine generates.
