Looks like the shaft was wound down too much for a while, also seems that you had no oil in since you have significant heat damage there. But if it all checks in you might be ok. I presume the shoulder on the shaft isnt meant to rest on anything? Yeah I'm not sure what's going on with that blueing on the metal, the box definitely had oil in while in use because I drained it out, didn't seem to be far off on the amount either The blue looks like welding heat to me though I don't see any welding on your pics. I can't imagine turning the wheel fast enough to heat that chunk of steel enough to blue it.

I haven't had on of these apart, but, maybe it was fitted without centering both the steering and box allowing it to move too far one way and not far enough the other? Just guessing because you wouldn't think a good design would let those parts mash together in any circumstances so perhaps something is very worn or missing completely. That "welding" heat blueing could be a sign that your steering box has been "fixed" previously.

No there's no sign of welding by the blue bit. Although further up on the "cage" part around the roller I've just noticed there are a couple of patches where the casting "roughness" has been smoothed off somehow whether by machine or by rubbing on something, but there's no corresponding marks inside the case. Also the bloke who got the bolt out said it was made a lot harder because there was a shit load of threadlock in with the bolt. Sounded a bit odd but maybe a sign someone's fucked about with it before. My steering was always very sloppy by the way and once I had the box off I could see how much play there was.
I don't see I have much choice but to Dremel the fucked bit (need to buy a Dremel first...) Then reassemble and hope for the best.

Which reminds me Mike James on tlb said he's had his apart so I need to have a chat with him, see what he thinks

Whatever the cause, it's clear that those parts are no meant to contact. I'm sure you can work out what's worn to allow that. I'd have done that before buggering about with the lid as you may end up skipping the whole thing.

I wouldn't of known about it without getting the lid off....

Aha great find that thread ,cheers Keith. And thanks for the box offer, hopefully won't need to take you up on it! So going by the pics in that thread I thankfully have no part missing. As far as I can work out the blueing on the shaft has been caused by that part of the shaft being the area that has ground down the rib in the case. That bit of the shaft seems to sit at a slight angle which is the lowest point, so was main area of friction. Which would suggest to me that it happened in one of the machine shops who had it. Sound reasonable??

Sound reasonable?? I was reading a thread on Samba that mentioned the blueing as a result of "brutal" manufacturing. There were some pictures like yours, the inside of the casting wasn't worn. It's in the bay window forum not far from the top. Good for pictures if nothing else. Not having had one apart, what is it that's (presumably) supposed to prevent the shaft moving that way?

Purely the adjustment on the round cover plate. The plate is threaded so the shaft screws into/through it, then there's a locknut on the outside to hold it. if you deliberately wound it right in for use , I'd imagine your steering would be way off so you'd correct it, and it wouldn't cause much, if any damage. I reckon though some twonk clamped it up funny to machine the bolt, and spun the shaft round at high speed , winding it right in and so chewing up the case.

If that shaft can slide to an fro then there will be corresponding steering wheel action with no corresponding road wheel action while it slides from one end to the other, and in your case mashes up the casing. Clearly this is wrong, you need to partially reassemble it and work out where the lateral play has come from. 👍

Will have a look later, I forget about other sites like the samba!

When you tighten the adjusting screw it pushes it that way. Normally it tightens against the other shaft and doesn't can't move far enough to cause your damage. Therefore I deduce the other shaft moved sideways (ball bearings fell out?) and the adjuster was tightened to take up the slack. What then felt like bottoming out of the adjuster was those two parts hitting, but the steering was still sloppy. Just waiting for my quiche to cook.

Yes the bushing in the cover wears out and it all goes sideways ..
