I am replacing top and bottom, I plan to use aftermarket bearings (complete set less than one OEM bearing from Yamaha and I am pretty sure its the same bearing) , but I am trying to figure out if there is a seal on the lower race. On the parts list I have it just shows the bearing. Has anyone done this and figured out if there is a seal what part number it is ?

I am sure I have seen a reference to this somewhere on the forum but cant find this now

Thanks
Scott
