Don't use a proper tool (bearing puller?) just tap them out using a hammer and drift. Use a hammer and socket to tap the new ones into place. Make sure the socket fits onto the outer race of the bearing not the inner race.

I used a hammer and drift to start the process then a slide hammer bearing puller (about £30 off eBay) to drive the bearings right out once I could get decent purchase on them (you need a gap so the jaws can get under it). Used a socket to drive the new ones in, being careful to make sure that no force was put on the inner races.

No need to use a bearing puller as once they've moved a bit they're easy to get out. You can always use the trick of heating the hub to help them out and in plus freezing the new bearings.

appreciate your wisdom but i'm fed up whaling on the end of a hammer,so a tool is what i'm after but i'm not sure if it's a standard bearing puller or blind bearing puller that i need.Seen some mighty dear one from the likes of symes-pikavant-any advice?

With a good drift a bearing can be removed in less than 5 blows. Most bearing pullers need to be assembled before use. You only really need them when the bearing is sitting in a hole with only one entrance.

If you've been whaling on the inner race with a hammer and drift and it isn't moving, check you've removed any circlips.

You might also have got it "wedged" at a slight angle (you should move round the inner race so it comes out square). If it is wedged, you're best to drive it back in then start again.

no i've not attempted anything yet,just thought it best to check if there was a simple tool that would make a clean job of it.
I get the impression it's not needed.

I find it much easier with a proper tool steel drift rather than a bolt and I usually make sure the end is square by filing/sanding it prior to use.

Done many of them this way, never had a problem (other than forgetting a circlip on occasion).

I noticed a lack of any videos on youtube showing how to remove motorcycle wheel bearings without the use of unecessarily expensive tools.

As it happens, I needed to remove some bearings from a wheel I got off the breakers so I videoed it.

Most of the video is of me battering away at one of the bearings that, as it turns out, was in pretty solid due to corrosion round the outside of it. As soon as I swapped onto the other one, it waltzed out. As soon as you get one of them moving, it all gets a lot easier.

I videoed the entire job which took 6 minutes but would have taken 2 if I'd started with the other bearing first (random chance).

I'll do another one of me fitting the new bearings once they arrive.

when i did my bearings on the cb550, best tip i got was heat the
hub with a heat gun, not roasting but just too hot to touch

few whacks at 12,6, 3 and 9 oclock and out it popped

As said use a drift to get them out, it works a treat. But make sure you keep the bearing straight otherwise it will lock up and not move.

And to get them back in, use a long bit of stud and 2nuts to wind them in like this:

Also that is copper grease to make it easier to get them back in.

As promised. Bearing fitting.

Not the best way, not the only way, but one way.

So 2 unedited videos. Old bearings out, new ones in. 14 minutes.
