Good To Know

Q: Should I replace this seal alone or with other engine seals? A: If you are already inside the engine, replacing related seals at the same time saves labor and lowers the chance of a second teardown. Inspect the crankcase area for other weeping seals before reassembly.

Q: Does this seal fit every 255 FSH Sport E 1800 from 2021 to 2026? A: This seal is listed for the 255 FSH Sport E 1800 across those model years, but seal and shaft dimensions can vary with serial number. Confirm your engine identification before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
