It's my first time changing transmission bearings and the new kit came with a "plate" on one of the bearings. The old bearing didn't have that plate so I'm kinda confused.

I guess it should stay on but one of you guys probably know the right answer?

I feel so stupid for asking this but at the same time I don't want to mess this up haha

There is a screw that holds the plate on so the bearings don't back out into the crankcase. Usually a short, flat head Phillips. Red loctite 

What bike is this?

That's a seal it can be removed if your referring to the black seal on the bearing. That looks like the transmission output shaft. If it is it would have a seal on one side facing out towards the outside to help keep dirt out. 

Now if it had the seal on both sides I can see the confusion. Because that would keep the oil out. 

Did you put it in backwards facing the wrong direction?

Yes but that bracket and screw only holds the outer race and not black "protection plate". Do you think that plate should be on the other side of the bearing and I mounted it wrong? I don't understand its function but it kinda makes more sense to let the gear rest on it haha.

And I think green loctite was used. I don't know if they have the same strength

It's for my rmz 250 2016

I just took a closer look and I think I fucked up. Looks like I should've put that black seal on the other side of the bearing so it's facing outwards.

Just gotta heat it up again and put my bearing puller to work. It won't get damaged if I'm gentle, right? Wink

And while i'm talking about bearings, the small bearing up to the right in that picture is for some reason slower than the rest. If I try to spin them they spin like regular bearings (shocking I know haha) but the smaller one I have to push. As soon as I stop, it stops immediately as well.
Is that acceptable or does it have to be replaced again? Thanks

As long as it spins smoothly with no grinding notchy feel, it is good. Make sure that the bearing with seal on it has a step on the outer race on the other side before you remove it. If not the retainer will not work.

Yeah the bearing was facing the right way, I just had to move the seal to the other side. Now I think I got everything right.

Thanks guys
