The Honda 73511-770-000 Primary Drive Sprocket (10T) is a genuine OEM component designed for FR600 and FR800 tillers. As a direct Honda OEM part, it is manufactured to the same specifications as the original, ensuring a correct fit without adaptation. Honda supersedes tiller drive components at serial breaks, so confirm your unit's serial number against the fitment table before ordering. This sprocket is the correct 10-tooth variant — verify this matches the sprocket your tiller originally carries.
Key Features
- Genuine OEM Drive Component — sourced directly from Honda, this sprocket meets the tooth count, pitch, and bore dimensions the FR600 and FR800 tiller drivetrains were engineered around
- 10-Tooth Variant — the (10T) designation identifies this as a specific sprocket variant; confirm your tiller's original sprocket tooth count before ordering
- Tiller Fitment — built for FR600 and FR800 tillers; check your serial number against the compatibility table to confirm this is the correct part for your production range
- Drive System Integrity — a worn or damaged primary drive sprocket causes slipping, uneven chain engagement, and loss of tilling force; replacing it restores proper power transfer to the working attachment
The Primary Drive Sprocket is the first sprocket in the tiller's drive chain, transferring rotational power from the engine output shaft toward the tine drive assembly. Its tooth count and pitch determine how that power is stepped down and delivered — a sprocket with worn or chipped teeth cannot maintain consistent chain engagement, leading to slippage, vibration, and reduced tilling performance. Replacing a worn sprocket restores smooth, consistent drive and protects the surrounding chain and driven components from accelerated wear.
