The Honda 90452-KG8-000 Washer (12.5MM) is a genuine OEM replacement built for FG400 and FG500 tillers and GC135, GC160, and GC190 horizontal shaft engines. Sourced directly from Honda, this washer matches the exact dimensions and specification of the original, ensuring a proper fit without modification. Verify your machine's serial number against the fitment table before ordering, as Honda updates part supersessions at serial breaks.
Key Features
- Genuine OEM Fit — manufactured by Honda to the same dimensional standard as the washer it replaces, so it seats correctly the first time
- Broad Fitment — listed for FG400 and FG500 tillers and GC135, GC160, and GC190 horizontal shaft engines, including multiple serial ranges across each model
- Serial Number Verification Advised — Honda supersedes hardware at defined serial breaks; check your unit's serial number against the fitment table to confirm part number 90452-KG8-000 is correct for your machine
A washer of this type distributes the clamping load of a fastener across a wider surface area, protecting the mating components from damage and maintaining consistent clamping force under the vibration loads common to tillers and small engines. Without the correct washer in place, fasteners can loosen prematurely or the contact surface can become damaged, compromising the integrity of the assembly it secures. Using the OEM-specified part ensures the load distribution matches Honda's original design intent.
