The Honda 90404-ZG3-000 Washer (10MM) is a genuine OEM component designed for GD320 and GD410 horizontal shaft diesel engines. As a factory-sourced part, it matches the exact dimensions and material specifications Honda requires for proper clamping and load distribution in these diesel powerplants. Confirm your engine's serial number against the fitment table before ordering to ensure this is the correct washer for your production run.
Key Features
- Genuine OEM Sourcing — supplied directly through Honda's parts network, so the 10MM dimensions meet the exact tolerances specified for GD-series diesel engines
- Direct-Fit Replacement — engineered to Honda's original specification for the GD320 and GD410, dropping in without modification
- Diesel-Engine Application — specified for Honda's horizontal shaft diesel engines, where consistent clamping load matters given the higher compression forces these engines generate
- Serial-Number Verification Recommended — Honda supersedes hardware at production breaks, so always match your engine's serial number to the fitment table to confirm part number 90404-ZG3-000 is correct for your unit
A washer distributes the clamping load of a fastener across a broader surface area, protecting the mating components from damage and maintaining consistent joint tension over time. In a diesel engine — where compression ratios and operating loads are higher than in a comparable petrol engine — proper clamping retention is especially important for keeping assemblies secure under sustained stress. When a washer is worn, deformed, or missing, the fastener it supports can loosen prematurely, leading to joint failure or component damage.
