The Honda 31218-ZA1-013 Yoke is a genuine OEM component built for a wide range of Honda engines, generators, tillers, riding mowers, and lawn tractors. This part is sourced directly from Honda and manufactured to the same specifications as the original, ensuring an exact match for the application. It is confirmed for GXV270, GXV340, and GXV390 vertical shaft engines, G300 and G400 horizontal shaft engines, the GX360 horizontal shaft engine, EMS4000, EMS4500, ES4500, ES6500, EV4000, and EX5500 generators, the FR700 tiller, H1011, H3011, and H3013 riding mowers, and H2013, H4013, H4514, HT3810, HT3813, and HT4213 lawn tractors. Because Honda supersedes parts at serial breaks, verify your unit's serial number against the fitment table before ordering.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this Yoke is manufactured to the same tolerances as the part it replaces, ensuring the connection it makes is as solid as the original.
- Broad Cross-Platform Fitment — covers vertical shaft engines, horizontal shaft engines, generators, a tiller, riding mowers, and lawn tractors, including GXV270, GXV340, GXV390, G300, G400, and GX360 engines among others.
- Serial Number Verification Recommended — Honda updates part numbers at production breaks, so confirm your machine's serial number against the fitment table to ensure this is the correct Yoke for your specific unit.
- Drop-In Replacement — as a genuine OEM part, this Yoke matches the original mounting interface and dimensions, so no adaptation or modification is needed during installation.
A yoke is a mechanical coupling component that transfers rotational or linear motion between connected shafts or assemblies within the drivetrain or control linkage of a machine. It acts as the bridge that keeps two moving elements engaged and properly aligned during operation. When a yoke wears, cracks, or fails, the connection between components becomes loose or breaks entirely, causing loss of drive, erratic control response, or a complete stoppage of the affected system.
