Hey, Was wondering if anyone has encountered what appeared to be a spacer/spiral washer/metal band looking thing between the seal and bearing in the rear hub. I was replacing my rear tire the other day and when I took it off it popped out, it looked like it had been pinched on one side. Any ideas? Does this piece serve a purpose or required for a better seal? BTW, this was on an 08 TE450. Thanks, -Jarrett
Its not one of those circlip rings is it? I think that's what you call it. My KTM had one of those on one side of the hub to hold the bearing in (but not the other side...go figure). It went between the bearing and the spacer into a slight groove in the hub.
I don't think so. Its not a solid piece of metal. Closest thing i can relate it to is the retainer ring that holds on the fork dust seals, basically a flexible spring o-ring, i can't figure out if its supposed to be in there or not. Maybe just an extra part some guy threw on by mistake at the factory.
I think I figured it out. Its the metal retainer ring that goes inside the seal and holds the inner part of the seal against the rear axel, must have popped out for some reason and got bound up between the seal and the bearing. I found this picture with a metal ring.
