Have verified vac advance, I said I was seeing 200-300mbar, which is 150-225 mmHg, which corresponds with the vac advance on the distributor chart.
@VolvoHordz dropped by with those parts from the other day, and we delved a bit deeper into the distributor to see if that random bit of wire, which feels like spring steel, if that belongs in the distributor or not.
There is definitely some kind of damage down in the mechanical advance, but it all moves freely. Notice the top of that prong is all bent and pancaked?
Looking at the exploded view of the distributor, I don't really see anything that looks like a spring, other than maybe this piece?
I'll take a closer look, but I think it's too long to sit inside the shaft like that.
Very strange.
The damaged prongs are more concerning though, they would interface with the vac advance plate to stop the two advances from being too independent of one another? Not sure.
This all came from Greenbook TP30432/2 Section 3, Group 34, Ignition Systems Repairs & Maintenance.
I've never seen it, but there might be a Construction & Function greenbook that accompanies the Repairs & Maintenance once, if anyone has a hardcopy of this Greenbook, could you maybe photograph the pages that explain the design of the non-contactless distributor?
