Need to remove the front wheel bearings. I've never done anything like this before but would like to give it a go. The spacer wont move far enough to allow a screwdriver to grip properly.

I found an interesting thread on the link below which mentions using a rawl bolt.

My question is what size rawl bolt should be used? My local DIY store doesn't stock anything near big enough to fit the bearing.

Any help and advice would be gratefully received.

Cheers

You can get bearing pullers specifically for this although a rawlbolt the same size as the spindle would be a reasonable redneck way to do it.

The rawl bolt you use needs to be the type with a split cone at the bottom, not the sleeve type, the size needs to be so that you can open the cone enough so that it will not pull out past the inner race once expanded but not so big that it will jam on the internal spacer/sleeve.
The bearing pullers are similar in method but more refined and use a slide hammer.
 
which ever method you use a hot air gun on the wheel will help,also new bearings in the freezer and hot air on the wheel on reassembly.I do have the correct tool to remove them which if you want to pick it up you are welcome to borrow or bring the wheel to me and i will do it.
 
Thanks for the replies and useful info fellas. I'm looking to keep costs down so a redneck solution would have been great.

I may well be taking up your kind offer autogs. I'll drop you a pm

Cheers
 
I used 18" of 10mm or even 15mm steel bar to drift the bearings out. You need a big lump hammer and heave on the bar to keep it pressed against the bearing edge. Angle grind the pointy end to a 30 degree slope to better dig into the bearing edge chamfer. When its all apart, file a groove into the sleeve inside. Next time the drift will slip less easily.

Put the wheel on 3' x 2" timbers to protect the rims and discs.

When you fit the new bearings be careful to knock them in far enough but not too far. If the sleeve is loose the bearings will be side loaded and fail very quickly. But the outer ring can be bashed in too far causing the same problem in the opposite direction.
 
you do like to over complicate every single task dont you?,once the bearing is seated in the recess its in you cant go to far once its in its in,the sound will change once its seated.its that simple,im surprised you didnt mention your diversion or a job on the punto or somehow blamed bmw for desigining it wrong or get a mention of the poor paint on an 08 adv or blah blah you really are a tedious fucker at times.
 
lol that's what keeps this place interesting. All the witty comments.....as well as all the useful info...

I do love Bendys suggestion of "round file to cut a 3mm deep groove in one end of the spacer bore" and will be doing that to mine once the old bearings are out. Thanks for the tip Bendy.
 
Thanks @lagalut. Getting the old bearing out is easy enough with a length of bar and a big hammer. How hard can it be? Filing the spacer tube is optional but makes life easier next time.

Ideally heat the wheel hub to 100 degrees. Easy enough on a wire wheel. Has anyone actually tried getting a cast alloy wheel hub to 100 degrees?

Simply slamming in new bearings is great way to find out how handy it is to have filed the spacer last time you did the job.
 
One of my favorite jobs replacing wheel bearings, I have no idea why just always enjoyed doing it.
Made a draw hammer years ago from a bit of all thread some nuts and a bit of cut and bored half shaft.
must have done thirty sets of wheel bearings with it.
 
Resurrecting the thread as I have to replace the bearing from my front wheel(s).

First time doing these specific bearings, and I want to learn how to do it right. I wanted to buy a bearing puller. I can see from videos online most people use the slide hammer type.

Any suggestions, pointers?
Thanks.
 
I have the slide hammer type tool and it works well,don't forget to heat the hub around the bearing area on the hub and put new bearings in the freezer the night before.

You can borrow my tool if you want to pick it up?

You're very kind, thanks!
No worries I was thinking of buying it anyway as it could be useful on the other bikes as well.
 
I have the proper internal bearing puller with the slide hammer type attachment, works very well, but I have to say that an M12 rawl bolt also works just fine, I've done two sets with the rawl bolt and it was easy. Secret is to heat up the wheel are surrounding the bearing with a hot air paint stripper gun first, if you do that the bearings will pull out with very little force, same trick to drop the new ones in. Put the bearings in the freezer overnight as well to make life easy.
