The Honda 90504-777-000 Thrust Washer (17MM) is a genuine OEM component designed for FR650 and FR750 tillers. As a direct Honda replacement, this part is manufactured to the same specification as the original, ensuring a correct fit without guesswork. Honda supersedes parts at serial breaks, so verify your tiller's serial number against the fitment table before ordering. This 17MM thrust washer is listed for both the FR650 and FR750 — confirm the part number 90504-777-000 against your machine's parts diagram to ensure you are selecting the right variant for your unit.
Key Features
- Genuine OEM Honda — sourced directly from Honda, this thrust washer meets the same dimensional tolerances as the part it replaces, maintaining the correct axial clearance in the drivetrain assembly.
- Correct 17MM Sizing — the (17MM) designation identifies this specific variant; match it to your parts diagram to confirm it is the right washer for your tiller before installation.
- FR650 and FR750 Fitment — listed for Honda FR650 and FR750 tillers; cross-reference your serial number with the compatibility table to confirm applicability to your specific machine.
- Axial Load Control — a worn or out-of-spec thrust washer allows unwanted end-play in a rotating shaft, accelerating wear on adjacent components and reducing drivetrain efficiency.
A thrust washer manages axial (end-to-end) load between rotating and stationary components in a drivetrain, preventing metal-to-metal contact along the shaft axis and controlling the amount of end-play present. In a rear-tine tiller like the FR650 and FR750, drivetrain components are subjected to continuous load as the tines engage the soil, making proper thrust management essential to smooth, consistent operation. When a thrust washer wears thin or fails, excessive end-play develops, which can cause accelerated wear on shafts, gears, and housings and lead to noisy or rough drivetrain operation.
