well, how do you get them outta there, i cant do it, i have been working on it for about 4 hours and havnt budged them one bit

 

I just replaced all of the bearing in my 86 250R engine. The easiest way i found to get them out, what to take a hole punch, and hammer, or a strong screw drive and a hammer and knock them out. This only works though if you don't care about the condition of the bearing once it's out. I was replacing all of my anyway since they were froze, so it was alright.

To get the bearings in, i would suggest finding a socket that fits the outside rim of the bearing perfectly, and gently tap around the socket with ball pin hammer, making sure it goes in equal on each side.

 

hey hondaman, thanks, hopefully you are still on so you can answer this one too. On the left side, the bearing had exploded, so the top part had already fallen off. But, that left the larger circle still in the axel. So how do i get that out, im going to try the other method now. thanks

 

My neighbor had some kind of special tool that you could use but i don't know what it is called. Maybe someone else on the forum knows what I am talking about?

 

surely someone else has changed bearings before, help me out,

I just dinally got the sleeve out last night and i was thinking it would be easier to get the bearings out after i got that out, but it wasnt. help

 

What works best for me is to take the carrier out, apply some WD-40 to the bearings, and then smack the end of the carrier down on a piece of wood. After a few good whacks, the bearings will slide out. If that doesn't work, you can try heating the carrier up a little with a torch to loosen things up.

Regards,

Whatever you decide to do...Be careful using an object that is not the same or close in size to the bearing. If you pound that bearing out of there crooked...your looking at not getting the new one to seat properly. Never hit one side..then the other...It has to come out evenly.
I would take the carrier to a place with a press. They will charge you next to nothing to press the bearings out with little damage to the carrier.

 

The best way I have found to remove the axle bearings is to take the carrier out of the bike and put it in the oven @ 400 degrees for 10 minutes. While the carrier is in the oven have your new bearings in the freezer. Remove the carrier from the oven and use a piece of brass or a large drift punch to knock out the old bearings. They should come out fairly easy. When you get them out take the new bearings out of the freezer and drop them in the carrier, no beating them in required. Don't forget to put the spacer in before you put the second bearing in. LOL! Be sure to open the windows in your house before you put the carrier in the oven because the grease will not smell to good when it is cooking.

 

well, i got them out, i used a slide hammer and it came out very easy. I guess my next question is what spacer are you talking about? Im sure ive seen it, it just is not clicking in my head what you are meaning by spacer. Well thanks alot. Oh what will freezing it do, im thinking if it makes it shrink a little big, how would the axel fit through it?

 

The spacer I was referring to is what you called the sleeve, the piece that goes between the bearings in the carrier. As far as the freezing of the bearings, it shrinks them just enough to let them be installed in the carrier easily when it is hot. I don't know how they will go in without the carrier being hot, but I imagine it still would be easier. The axle will still go in the bearings after they are installed, cooling them off just shrinks them for a minute or two.
