Bearing outer race stuck in hub. Help!

Recommended Posts

I was changing the wheel bearings on my 2002 yz85, and while I was taking the bearings out, both of 'em fell apart, leaving the outer race stuck in the hub, I did manage to get one of them out using a tire spoon and a jack handle for leverage, but now I am on the other side and the bearing came 99% out, and then just stopped. Its not going farther no matter how hard I try, it looks like the top has been squished in a little which is blocking the bearing from coming out completely, what can I do?

It looks wedged in there man. Unless it's just the pics the race at about 6 o'clock looks more recessed than 12. If the hub is truly mushroomed in it wont have any affect on the bearing coming out since the race is steel vs aluminum hub

Remove tires and heat wheel in oven at 300F, or may want to try heating with heat gun, just may sure you apply heat evenly around hub. Then just get a hook and should pop out.

Ive already tried heating it up with a blowtorch, it didnt really help.

Get a blind bearing tool, heat the hub and yank it out. The small amount of damage to the surface will break off during the process. If it leaves some burrs, I'd hit the edge with a little emory cloth to help with the installation of the new bearing.

Blowtorch:naughty:, it does not apply heat evenly and may screw up the hub.

Thanks for all the help guys, I did manage to get the bearing race out using some heat and a pair of long needle nose pliers that had kind of a bend at the tip so they could push onto the bearing, and a hammer. I heated it up even with a blow torch for about 3 minutes(yes, I know its a bad idea to use a blowtorch but it's all I had.) and yes, I did make sure to get the bearing out evenly, not get one side of the bearing completely out and then push the other side out. And the bearing just came right out. Heres a picture of the two bearing races.

Good for you, blowtorch heated evenly won't hurt it. Beating the hell out of the hub and bearing race will.

Koray, that hub is TOAST. Shaft and Housing tolerances, fit , finish, taper, roundness, etc are incredibly important. If any of these fall outside design parameters any new bearing will fail quickly and you'll be at this again in no time. Bearings are not necessarily round by themselves. They rely on the shaft or the housing for that. I guess if you don't travel too far from home not a big deal. Hate to see you get stranded tho. I see you don't want to invest in a new hub or wheel assembly. Hard to blame you as the bike may not be worth that much. Wishing you luck.

Oh, as a geek side note: What you removed from the hub was the bearing outer "Ring". The "Race" (short for raceway) is only the surface which contacts the rolling elements. Not that this matters other than I've been in the bearing business waaaay too long.

Technically,  a spherical ball bearing has two "races " inner and outer. Thats why they both have grooves..

Hey Strom. I'm not sure why you think the hub is toast? I didn't see any cracks or crazed area in the pic. Other than the surface thats pitted, what is it that makes it toast? BTW, never thought about the circle of perfection of the outer race. Good to know.

      Ok so I'm looking for opinions from those who have been on yz125s and 150 exc/xcw's and maybe the ktm 200's exc/xcw's. You gotta be out there.
      Here's the deal...I'm 5'7" 165lbs. A couple years back I was looking for a small bike for my wife to learn on and for me to play around with and race. Could only afford one bike. I got a '09 ktm 105 sx. Once I got it sprung for my weight it was great. I have been top five consistently in my local harescrambles B class, believe it or not. Ya, you were not the only ones shocked. And did pretty good in the local mx races as well, junior class up here in Canada. Lack of power was sometimes an issue but I learned to deal with it and just scream, scream, scream!
      However my wife is a complete beginner and she is scared of it. I have since moved her to a 4 stroke.
      Just got a mint '01 yz15 mid summer. Like less than 200 hrs! I have absolutely loved it on the mx track. Suspension is perfect and I love the extra power. I had planned to set it up for woods/mx with a suspension revalve. However, did a harescramble race a month ago that was really technical. Granted I have not done anything to the suspension minus clickers, had too much psi in the tires (13 front and 15 rear) (yes I know that's wonkey, I only had time to get a heavy duty tube in the front and had a stock tube in back. Less psi in the back would have been instant pinch flat because its so rocky) and it was running rich. I had to scream the thing to keep it running and even changed a plug mid race. Well I'm sure you can guess but it was the worst experience I have ever had on a motorcycle. The more open sections I passed a lot of people but the tech sections required way more effort than I liked and the suspension beat the hell out of me!!! Like my knees, wrists, and shoulders were just done. (I was out there for three hours).
      So keep in mind that I just came off a 105sx with suspension mods (set up for woods/mx). I have no problem slipping clutch and shifting precisely, yatta yatta. (I don't think the 105 would have done well here either due to even less power, however...) I've been second guessing fixing this 125 up for woods ever since I rode a friends '09 ktm 250xcw. I rode it on a local mx track. The power was just so effortless and I was absolutely floored by how the suspension worked. I never thought that I could hit the woops that hard and clear every jump on the track on an xcw and feel THAT good! It felt a lot heavier though, and I think the price tag on these things are going to be a stretch.
      So here's my question. I want the lightness of a 125, but want to be able to race both woods and mx. How does a 150 exc/xcw ENGINE compare to an mx 125 engine? I love the 125 engine, but more low end would be usefull in tech areas. But if there is not a huge difference, I will probably just revalve the yz for woods and go tubless, etc. The 150exc's are so expensive and I hardly ever even see one for sale unless its brand new. I don't want the weight of a 200/250/300. I barely touch the ground on a 125....so it has to at least be light. Is it worth waiting for a 150 engine? Thanks guys.

      Hi guys I have a 2018 yz250 looking at changing springs front and rear I'm 200 pound ride b class moto.
      Having problems choosing spring weights using the calculators as mx tech say I need .45 fork springs and 5.2 rear but racetech say .48kg forks and 5.8kg rear.
      What are other bigger guys

      Hey TT, I know there's endless topics on YZ250/ two stroke tuning in general but I have not been able to find one that helps me get my 09 YZ250 set up for my riding style and where I ride so I'm here asking for help. I got this bike around 1.5 years ago and have not known how to set it up properly. I know no one can give me a perfect set up but I'd like a good starting setup to work from and tweak to perfection. Throughout this time I've had this bike, its always been covering the bottom of the entire silencer and dripping all over the swing arm and rims with oil. Also, the joint between silencer and expansion pipe has oil around it too but I've heard I have to close the gap a little to squeeze the silencer a little tighter and stop the leakage there. I don't have too much experience messing with carbs but I've messed around with previous two strokes and tuned them a little better. I change the oil on my bike after 15-20 hours on it and clean and oil the air filter after almost every ride. The sparkplugs never last me more than a few months but recently have been lasting me no more than a few weeks. With the excess oil from the pipe and spark plug fouling you can see why I need to set my bike up to stop this. 
      The bike:
      Completely stock with V-Force 3 Reeds and a FMF Shorty silencer. 
      Usually running around 32:1 premix with 91 pump fuel because I prefer to keep it well lubricated instead of running rich.
      Riding:
      I ride enduro in Ontario, Canada. So mostly single track and some fire roads but nothing close to MX and not a lot of time wide open. Therefore, probably mostly 1/4-1/2 or 1/4-3/4 throttle range.
      Where I ride:
      Usually 0-500' above sea level. With temperatures ranging from around 15-35 degrees Celsius (55-95 Fahrenheit).
       
      If anyone can give me a setup to go from, that would be very much appreciated. Even multiple set ups for different temperature ranges or any suggestions would be much appreciated. Thanks and sorry for the long read, I just didn't want to leave anything out. Ask any questions if you have any, too.

      Hey guys... so I have a problem... I took the bike at Cal City, broke it in, and while I was doing so, the bike was bogging in first gear (Yes, first gear). Also it doesn't idle at all. I have to keep blipping it otherwise it'll stall. So I adjusted the screw circled in image 1. Well I was listening to the sound of the of the bike, yet the rpm's weren't increasing, and it was still stalling. So then, I unscrewed the screw in image 2, well I found out that it was fully twisted to the right. So then, I twisted it to the left, still nothing; it was still stalling... where's the idle screw? I am sure that the screw in image 1 is for the air/fuel mixture screw, and the screw in image 2 is the idle screw, just broken? I don't know, any and every help would be appreciated.
