For those stuck with the first generation seat swivel, you might find some relief in these modifications to get your swivel to rotate a bit more smoothly.
I took a good look at the mechanism to see why it gets hung up much of the time when rotating from front to back and vice versa. It turns out that it just needs some chamfers placed in the right spots.
Remove the seat by pulling the single pivot pin, then remove the front Hinge Brackets and grind a chamfer like this on the INSIDE of each one:
While I was at it, I also wanted to reduce the scraping against the seat by the swivel frame:
These things together seem to be a big help in getting the seat to swivel better. You still have to know when to raise and lower the seat during the rotation, but at least it doesn't get hung up and stuck anymore. It just works. Hope this helps.
