uh oh extra parts

[powerbrad5000]

I just got done replacing axle bearings in my 01 400ex and when I got done there was an o-ring left over. It is a big one that goes around the carrier. I think it goes behind the chain sprocket. Will it hurt anything to leave it off? To put it back on could I cheat and not remove the axle again? Thanks for your help.

did u serioulsy just ask if you could leave it off?

[powerbrad5000]

If I cant leave it off what does it do and why cant I leave it off

if it is the large o ring, i belive it is a dust seal. it probably wont hurt anything but they put it there for a reason:p

It is a black o-ring about 3 inches in diameter. I am not sure exactly where it came from but I am pretty sure it was behind the sprocket hub. I know they dont put parts on for no reason but just from looking at it I cant see why I should remove the axle again to put it back on. Thanks for your help.

are you sure it doesnt go in the brake stay:confused:

[chucked]

it goes around the bearing carrier to keep mud from getting between it and the bearing carrier

I just looked up the parts diagram and I bet that is where it is from I dont remember putting an o-ring back in there thank you very much for your help I am impressed by your ability to track that down. Thanks

no problem man. when folks send me that brake stay for coating, 9 times out of 10 they forget to remove it:p when you posted its size i pretty much figured what it was. in all honesty i dont think it does much at all, but to be safe id yank a hub and pull the stay and install it.

Behind brake stay I am pretty sure that is where it goes

pappys the one to ask haha

I havent run that O ring for quite a while now. After reinstalling the axle and adjusting your chain, that thing has always ripped so I just omit it. Sometimes I just take the strip of rubber after it rips and wedge it in there. I havent experienced any premature bearing failure or anything by not running it....

that is an o ring in the brake stay and right next to it by the carrier. both are simiilar sizes. i noticed when i took my axle out last time, one of them was broke. not sure how it happend but i replaced it.
