bearing problem

If anyone can remember i had a seized swing arm on my S4 but eventually we got the old pivot out 2 years ago now rebuilding the bike , now have fitted new ice cold bearings with heat lots of grease and a puller the seals are in and the circlips but sadly one of the new bearings there are 4 is not rolling smoothly,, whats the best way of getting it out for another new one , its an outer one which is fortnunate , I have various bearing pullers but they just wont catch the inner lip of the damn bearing going to get another bearing and seal , have a new pivot too,

also same problem on one of the new front wheel bearings pulled in ok but one of them is no good but its easy to knock out ,,

You'll want an internal bearing puller like this

or cheap and cheerful

If you don't have access to one and don't want to buy it, you could try knocking one up yourself using a shield anchor bolt e.g.

Luddite , I have a set of internal bearing pullers but they just wont engage the inner lip to get a grip on these little bearings unless i destroy the inner good bearing too , but that DIY solution might work

As it's the outer one get in there with a screwdriver, destroy the roller cage and dig out the rollers.
That will give you more of a chance of gripping the outer.

If it still won't grip you'll be able to collapse the outer inwards using that screwdriver with a hammer behind it.

It sounds brutal, but you are ditching the bearing anyway.

Yup I agree with Nasher, I remember reading a Triumph workshop manual (1955 Thunderbird) the section on removing the swinging arm spindle, "simply drift out with a hammer" in reality it required a sledge hammer.
