The Honda 90501-ZA0-003 Thrust Washer is a genuine OEM component designed for Honda EL5000, ES6500, EX5500, EV4010, EV6010, and EVD4010 generators. As a direct Honda OEM part, it is manufactured to the same standards as the original and carries the same part number used in Honda's own service documentation. This thrust washer is listed for the full range of generators above — verify your unit's serial number against the fitment table to confirm the correct application before ordering.
Key Features
- Genuine Honda OEM Part — sourced directly from Honda, ensuring the correct geometry and load-bearing characteristics for rotating or sliding assemblies within your generator
- Axial Load Management — a thrust washer controls axial movement and reduces wear between rotating and stationary surfaces; a worn or missing washer allows unwanted end-play that can accelerate component wear
- Broad Generator Compatibility — listed for the EL5000, ES6500, EX5500, EV4010, EV6010, and EVD4010, including Honda's conventional generator and RV generator lines
- Serial Number Verification Recommended — Honda updates parts at production breaks, so cross-check your generator's serial number against the fitment table to confirm part number 90501-ZA0-003 is correct for your unit
A thrust washer is a flat bearing component that manages axial (end-thrust) loads between two surfaces in relative motion — absorbing force along the shaft axis and keeping rotating parts properly spaced and aligned. Inside a generator, thrust washers prevent metal-to-metal contact at critical wear points, maintaining the dimensional tolerances that allow rotating assemblies to turn smoothly under load. When a thrust washer wears through or is missing, excessive end-play develops, leading to accelerated wear on the surrounding components and, eventually, mechanical damage that can take a generator out of service.
