The Honda 90454-428-000 Thrust Washer (20MM) is a genuine OEM component designed for a wide range of Honda engines and equipment, including GX120 horizontal shaft engines, BF2 and BF20 portable outboard motors, FR500, FR600, FR700, and FR800 tillers, F200 and F210 tillers, EG650 generators, HR17 and HR173 lawn mowers, and HP250 power carriers. As a direct Honda OEM part, it is manufactured to the same specification as the original, ensuring correct fit and function without guesswork. Because Honda supersedes parts across serial ranges, confirm your unit's serial number against the fitment table before ordering to make sure part number 90454-428-000 is correct for your machine.
Key Features
- Genuine OEM Thrust Control — manufactured by Honda to exact dimensional tolerances, this washer manages axial load and controls shaft end-play the way the original design requires
- Direct OEM Replacement — the 20MM sizing matches the original hardware specification, so this part installs without rework or substitution
- Broad Equipment Coverage — listed for Honda GX120 engines, BF2 and BF20 outboards, FR-series and F-series tillers, EG650 generators, HR-series lawn mowers, and HP250 power carriers; verify your serial number to confirm the correct application
- Serial Number Verification Recommended — Honda issues supersession updates at specific serial breaks, so checking your machine's serial number against the compatibility table is the surest way to confirm this is the right washer for your unit
A thrust washer controls axial movement along a rotating shaft, preventing the shaft from walking back and forth under load. By absorbing the thrust forces generated during operation, it protects mating components from accelerated wear and keeps internal clearances within the tolerances the equipment was designed to run at. When a thrust washer wears thin or is omitted, excessive end-play develops, which can lead to uneven loading on adjacent components and increased wear throughout the assembly.
