Radius Rod Washers & Bushes

[dasadrew]

Well, we've been around the horn a few times on this one, and I can't think why on those damned washers that it wasn't possible to write concave side and not dished side. Still, for me they are one and the same thing. Anyway, as the topic re-occurs every so often, I thought I'd float this here before popping it in the Technical Section to be lost forever!

Suits me, sir....

Only one of the washers is dished,the one on the out to the nut is plain,and you cant get the washes the wrong way round, as one has a bigger center hole than the other

Just refitted these and only had one dished washer each side, I thought it was just another fault with the car - the LH side (only) had the rubber block the wrong way round and an extra three thin washers under the nut so I wasn't surprised that there were only 2 dished ones when I thought it was supposed to be 4. But having looked again at Drew's diagram from the parts book, I can see the washer part nos are different.

Also Drew, perhaps there should be some labels on your diagram as my first thought on seeing it was 'are there supposed to be washers between the rubber and the bodywork?' Looking at it again I realised that they're the cups that the blocks sit in.

Good comments chaps - just what I was hoping to provoke. The ROM specifically talks of a dished washer at the beginning and at the end, so two seem to be meant. Also the quantities of 2 each are confusing as they refer to the quantity per car. I'll look at a few other editions of the parts and ROM manuals to dig deeper....

I'll be posting an update later, as I'm also discovering this along the route! Also Dave's comment (new to this) is significant, as explained by Peter at LD Parts. Also something which I had long wondered about.

[dasadrew]

An update. I think the plethora of solutions offered by the suppliers seems to confirm the confusion out there. In accordance with the feedback on this thread so far, it seems like Robsport have hit the nail on the head (no connection - and I might be wrong anyway!)

I agree about the one dished and one flat arrangement, but not with your latest drawing that shows the bushes with the radii against the body. The ROM is clear that the flat sides go against the body, which is the way I have always seen them, and fitted them myself.

Agree with DJT. Also agree with Robsport offering for the washers.
Fitting them the wrong way round (Rubber bushes) allows the radius rod to wear the chassis hole oval - seen that a few times.

agree with dave, but shouldn't the weld on plates show spot welded on cups?

[NeilR]

On the wheel arch side, yes it should be cupped.

****!! It was early this morning when I did the update - got the bushes mirrored!

Yes- but drawing those cupped ends is a pain and, since they're not in the parts book I didn't bother!

[MandM]

As this?

Is the strengthening plate only on the wheel arch side?
