DUST COVER, OIF FORK ABS
Dust cover for the steering head bearing on oil-in-frame Triumph forks, keeps grit off the taper roller bearings.
This is the steering head bearing dust cover for the oil-in-frame Triumph, listed in the parts book as DUST COVER, OIF FORK ABS and carried under the earlier alias H4028. It sits up at the top of the steering neck where the front forks meet the frame, keeping grit and road spray off the taper roller steering head bearings underneath.

On the OIF chassis this cover works alongside the steering neck bearing assembly to keep that area running clean, which matters since the steering head bearings take a beating from weather and road grime over the years. It shows up in the catalog under the TELESCOPIC FRONT FORK figure across a run of years from the early '70s through the end of the decade.
If your parts book lists this under the older H4028 number, that's the same physical part under its pre-OIF-era numbering. Worth a look any time you're servicing the steering head bearings on one of these frames.
