Ok is there a secret to removing the needle roller bearings from the front arms?

Struggled like mad to remove them

Thanks in advance

[maccers]

Tap them out with a drift they shoud just plop out. Use the old one as a drift to put the news one in.

made a quick and nasty tool to knock them out, behind the bearing is a gap, hook of the tool gets in the gap ..

 

insert from opposite end to bearing you are removing

[Guess-Works.com]

Yes, it's called a bearing puller...

Bought a set to see if they where as good as people said and they didnt do squat! That one looks like the proper tool vipernoir!

[Vipernoir]

Proper tools are the only way to go if you can get hold of them,

The problem with the proper tool is £70 is a lot of money to spend on a tool that will only be used once or twice. It seems my toolbox is full of such tools (cone compression and clutch oil seal tools come to mind) .

 

There are lots of ways of removing bearings without the proper tool that do just as good a job. Have a search on here for top arm bearing removal.

Did you even read Guesswork's post?

[cian]

Yep sure did but those are nothing like the video

Bearing pullers are readily available, if a bit expensive. They are not specific to the Mini, as needle rollers are used in many places. Don't bother with the slide hammer type, as a very tight bearing (common on Minis) needs something more powerful. Or, get a slide hammer type and be prepared to fit some kind of spacer and nut so you can apply a more positive pull

 

See here for lots of pulling equipment:

This shows how to use it and what bits, such as the counterstay, you need:

Or Amazon do a set:

This article by Timken shows several techniques for different situations:

Here are some "proper" tools:

Finally, this shows the bearings on a rear radius arm being extracted, exactly the same principle.

As always, Google will get you the answers quicker than any forum. Try searching for "bearing extractor" or "internal bearing puller" etc

Great work tiger99

[MiniTim71]

This looks like a very simple way to do it.

I am planning a total front suspension rebuild and have bought some M7 x 22mm washers to see if this works ....
