The Honda 91557-777-000 Input Shaft Collar is a genuine OEM component designed for FR650 and FR750 tillers. As a direct Honda OEM part, it is manufactured to the same standards as the original and carries the correct dimensions to seat properly on the input shaft without modification. This collar is listed for both the FR650 and FR750 — confirm your serial number against the fitment table to ensure this is the correct version for your unit.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this collar meets the same dimensional tolerances as the original part it replaces, ensuring proper shaft engagement on FR650 and FR750 tillers.
- Exact Replacement — designed to install in place of the original with no reworking of the shaft or surrounding components required.
- Serial Number Verification Recommended — Honda supersedes parts at production breaks, so check your tiller's serial number against the fitment table before ordering to confirm this is the right collar for your machine.
- Drivetrain Integrity — a worn or damaged input shaft collar can allow unwanted movement on the shaft, leading to vibration, imprecise power transfer, or accelerated wear on adjacent components.
The input shaft collar is a precisely sized ring that locates and retains position on the tiller's input shaft, keeping rotating components correctly spaced and aligned within the drivetrain. It works in conjunction with the shaft and surrounding hardware to maintain consistent engagement between the engine's power output and the tiller's working components. When this collar wears, cracks, or loses its fit, shaft play increases and the drivetrain can suffer damage that extends well beyond the collar itself.
