The Honda 90452-166-600 Thrust Washer (12mm) is a genuine OEM component designed for a wide range of Honda vertical shaft engines, lawn mowers, lawn tractors, and multi-purpose tractors. As an authentic Honda part, it meets the exact dimensional and material standards Honda specifies for this application, ensuring a drop-in fit without modification. This thrust washer is listed for models including GXV140, GXV160, HR194, HR214, HR216, HRA214, HRA216, HRC216, HRM21, HRS21, HT3810, HT3813, HT4213, H5013, H5518, and RT5000 — verify your serial number against the fitment table to confirm the correct part for your unit.
Key Features
- Genuine Honda OEM — sourced directly from Honda's parts catalog, this thrust washer matches the original specification for bore diameter and thickness, so axial clearance is controlled exactly as Honda intended.
- Broad Fitment — listed for GXV140 and GXV160 vertical shaft engines, a range of Honda lawn mowers including the HR and HRC series, HT lawn tractors, and H-series and RT5000 multi-purpose tractors.
- Serial Number Verification Recommended — Honda supersedes parts at production breaks, so confirm your machine's serial number against the fitment table before ordering to ensure part number 90452-166-600 is correct for your serial range.
- Axial Load Control — a correctly sized thrust washer maintains proper shaft end-play; a worn or undersized washer allows excess axial movement that accelerates wear on adjacent rotating components.
A thrust washer is a flat bearing element positioned along a rotating shaft to absorb axial (end-thrust) loads and maintain the correct spacing between moving components. In Honda vertical shaft engines and the equipment they power — mowers, tractors, and multi-purpose machines — thrust washers prevent metal-to-metal contact between the shaft shoulder and the adjacent housing or gear face. When a thrust washer wears thin or is damaged, shaft end-play increases, leading to accelerated wear on surrounding components and, in time, loss of smooth, consistent operation.
