Rear Radius Arm.
Turbo Mini Forums

Right

Brought 2 Rear Radius arm rebuild kits, checked everything there all fine so fitted one set to my Drivers side not an issue but now i get on to my passenger side radius arm and it has 2 roller bearings fitted into it, instead of a Roller bearing on the outside and Bush on the inside, the bush is smaller that the bearing and it don't fit into the rear radius arm it has good 0.3 or 0.4 mm round the bush

So Do I need a new Radius arm or can it be fix please?

nothing on this mini has gone right at all...

Thanks

As far as I'm aware they need reeming in

You press the bush into the radius arm then ream the centre of the bush to accept the pin James. What he has is a roller bearing fitted in place of the bush which is bigger than the bush, so it moves about, if I read the OP right. I'm sure Tom Fenton knew of something that may be a solution to your problem but I can't for the life of me think what the stuff is called. He was on about it last in regards to a slack outer race of a wheel bearing in a hub.

Carl your on the money, been told on the 16 valve forum that it might be a metro rear arm as they had twin roller bearings, would twin rollers be better?

Its only the bush that wears out, leave the two roller bearings in there they'll be fine

I seriously doubt it!

Ive been told to change the arm to get bush and bearing :S I am confused now

I understand what others don't seam to have picked up on

You have one radius arm which has been fitted with two needle roller bearings instead of one needle roller and one bush.

If you want to fit the bush, where some on had fitted the needle roller, you'll have to replace the whole arm. I'm not sure that Loctite bearing retainer would be up to the longevity of the task in hand

However, as others have said, you will need to ream the bushes in both arms to be able to fit the spindles.

In all honesty I don't see why you can't fit needle rollers all round anyway. I've heard all sorts of reasons, but I don't think they are justified when the Metro had neeldes all round and the front top arm has needles all round. I think it was Austin just being cheap skates.

I'm sure I've heard of something where somebody has said there is a radius arm with a bigger track width than the mini version, it's not the metro one is it? Then you'd end up with a strange setup on the rear end. Not sure on this, just something that somebody might be able to clear up.

the metro arms have a wider track, but the lever ratio is also different. You'd know if you had one mini and one metro arm. Im not sure if the metro arms had the shock pin stub axles either not to mention them being more square in shape

Had a look at metro Arm and the Mini arm and my too are Mini Radius arms so its all good but Ill try get hold of a set of radius arms from my mate and have twin rollers and then standard set up and see witch ones are better :) can't lose nothing doing testing
