The Honda 91371-733-000 Transmission Case O-Ring An is a genuine OEM seal designed for Honda F401, F501, FC600, FG400, and FG500 tillers. As a direct Honda OEM component, this seal is manufactured to the exact dimensions and durometer required for the transmission case on these machines, ensuring a proper, lasting fit without guesswork or modification. Verify your tiller's model and serial number against the fitment table before ordering, as Honda supersedes sealing components at serial breaks and the correct part number matters.

Key Features

  • Transmission Case Sealing — a correctly seated O-ring keeps transmission oil in and contamination out; a deteriorated or incorrectly sized seal allows oil to weep from the case and introduces dirt that accelerates internal wear.
  • Tiller Fitment — listed for F401, F501, FC600, FG400, and FG500 Honda tillers; confirm your model and serial number against the compatibility table to ensure this is the right variant for your unit.
  • Part Number Verification — Honda uses part number 91371-733-000 to identify this specific O-ring profile within the transmission case assembly; always cross-reference this number against your Honda parts diagram before installation.

The Transmission Case O-Ring A seats within the transmission case of Honda tillers, forming a fluid-tight seal that retains gear oil inside the housing and prevents external moisture and debris from entering. This seal is critical to maintaining proper lubrication of the transmission's internal components — without it, oil loss leads to premature gear wear and eventual transmission failure. When the O-ring degrades, flattens, or takes a set over time, it loses the ability to maintain that seal, making periodic inspection and timely replacement an important part of tiller maintenance.
