The Honda 91402-Z4M-003 Special Washer is a genuine OEM component designed for GX160 and GX200 horizontal shaft engines. As a direct Honda part, this washer is manufactured to the exact dimensions and specifications Honda engineers called for, ensuring a proper fit without guesswork. Confirm your engine's serial number against the fitment table before ordering, as Honda updates part numbers at specific production breaks.
Key Features
- Genuine OEM Sourcing — sourced directly from Honda, this washer matches the original part in every dimension, so it seats and functions exactly as the engine was designed to require.
- Correct Fitment for GX160 and GX200 Engines — listed for GX160 and GX200 horizontal shaft engines; verify your serial number against the fitment table to confirm this is the right part for your specific unit.
- Serial-Range Awareness — Honda supersedes hardware at production breaks, so checking your engine's serial number before ordering is the surest way to get the right washer the first time.
A special washer in a Honda engine serves a precise mechanical purpose that a standard washer cannot reliably fulfill — its specific dimensions, bore size, or profile are engineered to control load distribution, set the correct clamping force, or position a component accurately within the assembly. Using the correct part keeps the surrounding components properly seated and functioning as intended. Installing a washer that does not match Honda's specification can lead to uneven load distribution, accelerated wear on adjacent parts, or assembly that does not torque correctly.
