If you've ever tried it, wheel bearing removal can be a frustrating and sometimes expensive trip filled with expletives! Here is a technique that I found and thought I might pass on.
Here's how to remove the bearings from a CB750K rear hub.
First the tools you'll need:
1. Hammer - obviously
2. Wrench
3. Expanding sleeve anchor - these are usually used for holding things down to concrete and can be found at Lowe's, Home Depot, Fastenal, etc.
4. Drift - I used a long piece of steel rod
Now insert the anchor inside the wheel bearing just enough to reach the bottom of the bearing, about 3'4".
Place the drift inside the wheel hub. Take your time and give it a couple of good hits and pretty soon the bearing will pop right out. You may have to tighten the sleeve a few times until you get a good friction fit.
That's it! Now you can take all that spare time you've just created and go have a cold beverage...
Does this process ruin the inner race of the bearing, or could it be reused. Also I have never installed bearings, but could you simply throw them in the freezer for a couple hours and then pound them in or would that not work?
I NEVER re use wheel bearings... EVER! i had one freeze up on me at 45 on a back road, locked up the front tire on me and i went flyn! only new every time... yes you stick them in the freezer, after a few hours fit it into the hub, get a socket that matches the size of the outter race, lightly tap the socket over the bearing in a circular motion... till it seats... all done DO NOT re use the bearing!
god I feel like an idiot. I spent the better half of an entire day trying to get mine out with a blind bearing puller. Finally turned the plug around and whacked it out from the other side. Took all of ten minutes. I thought I was strong enough but turns out that knowledge really is the greatest power...
I spent $2.24 on this bolt and worked nicely removing the bearings from both my front and rear mags off my 80' KZ750. Once I had one side out I just used a large socket to pop out the other side.
Just make sure you get the right size concrete bolt. I took my new bearing into home depot to size up the right one.
Very neat trick. I've had a blind hole bearing puller from Harbor Freight for about 5 years now and removed hundreds of bearings with it and never spent more than a minute pulling them.
Brilliant. And yes, removing a bearing using the inside race (regardless of a $1 tool or a $200 tool) will effectively ruin the bearing. But there's no other way to remove it, and no real good reason to remove the bearing unless you're replacing it anyhow.
another good trick is to slice a bolt down the center... then run a flat head screw driver though it to expand it iside the race... pop it with a hammer. works great! costs you next to nothing to make several sized... hell i have a $ bearing puller and i still use my bolts once in a while on stubborn bearings
Major bump from the dead, but I just wanted to thank you for taking a quick second to post this. Tried going the punch route as shown in my Suzuki manual, but I ran over to Home Depot and these babies did the trick. Thanks!
