Fork oil seal orientation

[DaveR]

Just to be sure before installing the new seals - the side marked top faces up and is adjacent to the washer and clip and the bottom side with compression spring faces down to the oil side? I've looked at the FM and Google, apparently that piece of information is so obvious it isn't notable.

I'm due for a fork seal rebuild on my "T". Thanks for the insight.

Not sure if you're asking for an answer....but if you are then yes - the orientation as per your pictures is correct.

[DaveR]

Thanks Hillsy. I was 95% sure that was the orientation of the old ones when removed a few months ago but hoped someone could verify it. It looks like they could fit either way.

The "U" side of an oil seal faces the oil....or in an application where there is oil on both sides (like inside an old Brit bike gearbox / primary) the "U" side faces the side with the higher oil pressure so the seal flares out aiding the sealing process.

Also, it's a damn side easier to drift the seal into the fork leg by hitting the flat side

Yup, the tiny spring that goes around in a circle - that's the bottom side.

another way to answer the question: The printing on the seal is always "up".
