The Honda 90451-Z1T-000 Thrust Washer (6MM) is a genuine OEM component designed for a wide range of Honda engines and equipment, including GX200 horizontal shaft engines, GCV170 and GCV200 vertical shaft engines, GXV160 vertical shaft engines, HRC216, HRN216, and HRX217 lawn mowers, the EP2500 generator, and the FC600 tiller. As a direct Honda OEM part, it is manufactured to the exact tolerances required for proper axial load management in the assemblies it serves. Confirm your machine's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and this listing covers multiple equipment lines.
Key Features
- Genuine Honda OEM — sourced directly from Honda's parts catalog, ensuring the dimensional accuracy a thrust washer depends on to control axial movement without binding or excessive play
- Broad Equipment Coverage — listed for GX200 and GCV200 engines, GXV160 and GCV170 vertical shaft engines, HRC216, HRN216, and HRX217 lawn mowers, the EP2500 generator, and the FC600 tiller, including both GX200 horizontal shaft and multiple vertical shaft applications
- Verify Before Installing — Honda updates part numbers at serial breaks across its engine and equipment lines; always match your serial number to the fitment table to confirm this is the correct part for your specific unit
- Critical Fit Dimension — the 6MM size designation is the defining specification; an incorrectly sized thrust washer will not control end-play properly, leading to premature wear on adjoining rotating components
A thrust washer is a flat bearing component positioned between two surfaces that move relative to each other along a shaft's axis. Its job is to absorb axial loads — forces that push or pull along the length of a shaft — and keep rotating parts from grinding directly against housings or other components. When a thrust washer wears thin or is missing entirely, the shaft it supports develops excessive end-play, which accelerates wear on the surrounding assembly and can lead to noise, vibration, or loss of smooth mechanical motion. Installing the correct washer to the correct thickness restores proper axial clearance and protects the components around it.
