Radius arm problem

[Aginley]

Just rebuilt the arm and I’ve tightened it up and I have a lot of side play.
See video below.
Any recommendations chaps

You will until it has the thickness of the subframe on the inner end and the bracket on the outer end

[Aginley]

The brackets go the other side of the thrust washer though don’t they

[Dearg1275]

Either machine the pin down, relieve the thrust washers or source a shorter pin. It could be wear on the radius arm ends particularly if it has not been well greased over the years.

There is an earlier thread about this problem.http://mk1-forum.net/viewtopic.php?f=3& ... at#p219742

Something doesn't look right with the outer end of the arm - there doesn't seem to be a relieved section for the rubber seal to sit around, meaning the arm could be a few mm narrower than it should be?

[Andrew1967]

Agree with Graeme, that doesn’t look right on the outer side.

[Aginley]

Anyone got a pair of refurbished ones? Nightmare

[Bitsilly]

I think I have one and possibly a pair.
They are not re-conditioned though and as they came with the car as spares I don't know a lot about them.
I'll have a look tonight.
They are yours if you want them.

Just before I send them to Al, this is what I told him:

The good news is they both look like the threads etc are in good nick.
The other ends are not missing that shoulder,,,BUT
One of them appears to be hollow between the holes, the other isn't?
It is like there is a pipe bridging between the holes on one, but not the other.
It may be terminal.
I know there is an early type and a later type.

Can anyone comment?
Cheers

AFAIK all rear radius arms are hollow, hence the grease tube. Some do have a metal tube fitted for the grease tube rather than the more usual plastic one. The plastic ones are a bit crap and easily broken, beware they are tapered and must be installed the right way round!

[Andrew1967]

Sounds like the grease tube is missing on one of them. This fits in between the bush and the bearing.

Means when greasing you'd use a litre of grease to fill up the inside of the radius arm

[GraemeC]

What do you mean by 'between the holes'? Where the pin goes through?

If so then there should be a tube in place, either a metal one or a plastic one. If the bearing is missing it will fall out (I can't remember if it can come out of the bush end too).

No the end of the world if it is missing, assuming the arm is to be rebuilt anyway. However it does mean that the arm could be packed full of grease if the arm has been used without the tube there.

[Bitsilly]

Nice one gentlemen !
There is definitely a grease tube missing.
That it is tapered makes sense.
Seems the tubes come with the rebuild kit too.
