The Honda 23417-734-000 Auxiliary Idle Gear (25T/17T) is a genuine OEM component designed for FR600 and FR800 tillers. This gear is sourced directly from Honda and carries the exact tooth count — 25 teeth on one face, 17 on the other — required for correct power transfer within the transmission. As a genuine Honda part, it meets every original specification for the FR600 and FR800, making it the straightforward choice when the original gear is worn or damaged. Confirm your machine's serial number against the fitment table before ordering, as Honda updates parts at specific serial breaks.
Key Features
- Correct Gear Geometry — the 25T/17T tooth configuration matches the original Honda specification exactly, ensuring proper mesh and smooth power flow through the tiller's transmission
- Genuine OEM Part — sourced directly from Honda, so there is no guesswork about whether the tooth profile, pitch, or dimensions will match what came out of your machine
- Fits FR600 and FR800 Tillers — designed specifically for these Honda rear-tine tillers; verify your serial number against the fitment table to confirm this is the correct supersession for your unit
- Transmission Integrity — a worn or chipped idle gear causes rough engagement, gear noise, and loss of drive to the tines; replacing it restores clean, consistent power transfer
The Auxiliary Idle Gear (25T/17T) sits within the tiller's transmission and serves as an intermediate gear in the drive train, transmitting rotational power between shafts at the ratio its dual tooth counts define. Its two gear faces — 25 teeth on one side and 17 on the other — allow the transmission to step speed or torque between adjacent gears and keep drive to the tines smooth and consistent. When this gear wears, chips, or fails, the result is rough or noisy engagement, slipping drive, or a complete loss of tine rotation, making prompt replacement essential to keeping the tiller productive.
