Lol, it was about ten and a half minutes! It got progressively worse again on the dual carriageway then the dashboard dissapeared in smoke as I indicated and the flasher unit burnt out! All a bit too exciting. The wiring fault shouldn't be too bad to trace but I'll have to leave her parked up till the transmission's sorted. Might do some local pottering round in her though, I was in London with her yesterday (after I got the indicators to work again for a bit) and she's a right laugh hurtling around in the traffic!

Yep. Had that on a 66. Either swap the primary whole, or find a good centrifugal weight carrier assembly. Primary Unit Internals NS 003 by macplaxton, on Flickr If you look very closely (click for a larger version) the pivot pin to the right-hand weight is missing it's clip and the hole is oval. In this case, it hadn't jammed it up, but it had made it rather floppy in comparison to the good side. If you look very closely above the right-hand weight itself, you can see that the diaphragm spring is broken at its circumference too. Only other thing I can think of is working out some sort of method of reliably sleeving the hole, without changing the weight/balance of it. The oval hole should be quite easy to fix take it off and get it drilled out and then a man with a lath could soon wiz uo a sleeve to go in there if the shaft is worn this would need making round again or a new one/ made one could be used.

It's not impossible to fix (so don't chuck anything out), but given it's rotational speed, it'd really need balancing again, and balancing those things isn't particularly the work of a moment either.

Don't worry, nothing's going to end up in a bin! We were having a discussion at work today about how to re-balance the unit afterwards. We think if you put the weight carrier on a bearing you could then balance it on evening out its tendency to tilt through gravity.
The weight that's run its bearing has chewed up about an eighth of an inch of cast iron out of the carrier so its going to be a challenge to rectify that.
As a technical question, are the weight carriers on both sides meant to be aligned in the same plane? For example if the weights on the offside are in a horizontal position are they also in the same position on the nearside for balance. I have a feeling that I'm not the first person to take this transmission to bits.

Well I'm up at this hour because I'm pencilled in for night shifts starting tonight...
I haven't thought much about balancing, but I do know that the whole primary is dynamically balanced as an entire assembly. If the unit has been apart without marking it first so everything goes back the same way, then it's likely to vibrate badly.
The weight carriers on both sides are aligned in the same plane. The cross shaft is solid and there is a vacuum hole in either end which aligns with a corresponding hole in the weight carrier. There is only so many ways it can go back together...

Many thanks, I suspect it may all be a bit beyond saving but I'll see what I can do with it. I've got rather fond of the car so its got to be sorted one way or another lol.

Well not beyond saving, just too much of a time consuming ball-ache to bother.
If only there were oodles of Varios out there to be worthwhile building a balance rig.

There are balancing rigs in the Netherlands (3 of them iirc) which are in use today, I'm sure with a few enquiries we could find out who has them, I should think care of the DCN (perhaps Mr deBruin may know). Could be worth sending off to them although whether that would be cheaper than sourcing a good used unit (or less of a ball-ache) is another matter. An option nonetheless though.

It'd be very expensive.
Just the shipping on a 40kg lump would stick a massive hole in the budget.

Surely a daf express road trip could be in order.
