How the heck do I pull the bearings out of my GS and GSXR wheels, and then get the, back in?
Thanks much

You don't, or at least you shouldn't. Bearings can be damaged driving them out and it's best to put in new ones. I just put new wheel bearings in my 02 and they were $10-11 each from Ron Ayers, you can probably take your old ones to a local bearing place and get them for much less. Bearings are too cheap to use the old ones over.
You can reach thru one bearing and drive out the opposite one and then drive out the first one. You need a long pin punch, screwdriver, or something to drive them out. I used a long 3/8 drive extension to knock them out, it was handy. :) You need a large socket or piece of PCV tubing or something else just a bit smaller than the brg OD to drive the new ones in without damaging the brg seals/shields.
Take a long Drift or Punch and Knock them out.Slide the Punch thru the Axel Hole on One side and Rest it on the Race on the Other side.Take a Hammer and Knock on the Drift and working it around until the First on comes out.Knock the second one out.Take the New Bearings and Put them in the Freezer for Several Hours.If you have a Large Chest type Freezer stick the wheel in too. :thumb:When you go to Install them everything will be Shrunk due to the Cold.When you install them find a Socket or Piece of Pipe the Same Circumference as the Outside race of the Bearings.Make sure you knock the in straight.When you put the Spacer and Last bearing in make sure you don't go too far.If you do it will lock the Spacer in tight Against the Bearing Races and the Wheel will spin on the Axel instead of the bearings doing the Work.Not Only that it will be a pain in the Ass to try to get the Bearings Unjammed since there won't be Enough room to get a Punch back in to knock them Loose.Believe me I've been there and Got the T Shirt and a Brand New Laced up wheel with Locked bearings. :mad: Luckily I worked on it on a Cold enough day that everyting Shrunk enough that I was Able to Jar them loose without much Effort. :thumb:

Mmmmmm, I don't understand that. When the wheel is put in the bike the axle nut is tightened down it's all clamped up tight together thru the brgs and spacers. The length of the specer between the wheel brgs is slightly shorter than the distance between the c'bores in the wheel hub where the brgs seat so that this clamping of them tight together will give the wheel brgs the proper preload.
There is another spacer between the left wheel brg and the outside cush drive brg that was missing on my 02 wheel that caused overloading of the wheel brgs and caused the brg failure. The spacers take the clamping load of the axle tightening.
I found the new bearings went in easily w/o chilling them, all done at room temperature.
Jug,
you are scareing me
freeze the brg
HEAT the hub
for negative interferance application
jack is correct. all them spacers and brgs are tight against each other when the wheel is mounted
really he is.....!!!!
hi Jack
< hi Jack >
Don't say that on a plane. :laugh:
Oops it is Heat the Hub isn't it. :oops: :oops: :oops: No wonder I was Having a little Trouble. :laugh: :laugh: OK don't freeze the Rim.Of course I've never Had to heat one to get the Bearings in and Always Freeze my Ass off in a Cold Barn during the winter when I do get time to work on my Bikes. :laugh: I figured Since All of the Parts are Always Frozen thats Why everything Went so Smooth. :laugh: :laugh:
Actually I did get the Bearings too tight in the GT750 Rim I was Building.Must have Been a difference in tolerences. :dunno_white: :dunno_white: Both Bearings were Going in Dead Straight too.I even robbed the Inner Spacer from an identical NOS GT750 Wheel that had been Stored In the wrong Place and Had the Peeling off of the rim. :icon_confused:
Easier installation of anything press fit. Just remember:
Freeze the male
Heat the female
We use liquid nitrogen and low temp ovens ( <900F ) to assemble prop shafts all the time.
Nothing like a 600F temperature difference to make multiple ton objects 'like' each other. :thumb:
By the way, if you try to do it the opposite direction you'll just ruin another hammer! :o
MinnesotaCafe check out Gopher Bearing on Hwy 280 and University Ave good place and good prices. Just bring the bearing down with you and they will get you the right one if they have it in stock.
When I did mine I used a section of thick PVC pipe that was just a smidgen smaller than the diameter than the bearing. Use a short piece though, like about 1-2 tall because you dont have to drive them in very far. I put a piece of metal then on top of the PVC to make sure it when in straight.
DO NOT FORGET THE MIDDLE AXLE SPACER BETWEEN THE BEARING WHEN REINSTALLING!!!!
I did and had to ruin a brand new bearing because of forgetting about it.
Thanks all, I tried unsucessfully for a while with a piece of steel tubing and a BFH, on the wheel that I didn't need the bearings on, (just the center spacer) and no luck. I think the previous owner left the wheel outside or something, because the bearings that are in there are a little rusty so I'm worried that they might be rusted in? Is that possible? Otherwise they're jammed, or cocked sideways.
For the time being, I just put on the old wheel, since the bearings were luckily the first thing I attempted, and I'm heading on a camping trip with my bike. When I get time again, I'll go at this again, and let you know how everthing goes.
Coll - Will do, thanks much for the tip, do you have a GS that you rie on the street, or just the track?
Jughead - heat the bearings, freeze the wheel ... got it :laugh:
Jack and Werase - thanks much
