Great advice - very easy mistake to make
Check..... direction of rotation is correct (anti-clockwise). Firing order 153624.

Ok, The picture of the underside of the rotor button shows only a piece of metal on one side. The rotors usually have a metal section that presses into the button with a piece coming up on both sides and this locks the button in place. Does yours fit on facing either direction. The side with the missing piece should line up with the flat on the shaft. If it goes on both ways it should be replaced. I will post a picture shortly.

same design - and the same brand as on my photos
1. the shaft has a bevel on it - so it looks like the letter "D" from the top
2. the metal spring in the photo simply keeps the rotor against the shaft. the flat protrusion then slides into the bevelled section of the shaft. only goes on one way.
i went to burson and the bosch replacement has a different design, but also goes one way . the same way
can anyone identify the distributor ? the only difference between stock 240 and my one seems to be that the condenser is on the inside, not outside
the only remaining questions is - what side of the shaft is the bottom slot cut? there are only 2 options as you look at the bottom of the shaft
a. the small halfmoon is on the SAME side as the bevel eg the flat side of the "D"
b. it is on the OPPOSITE side

i don;t think so - see comments above. the shaft is one piece with the slots and bevels cut it into it. or at least that's what i remember

Disregard - just read you can only install one way

The distributor shaft isn't one solid piece all the way through it's actually two pieces to allow the mechanical advance to work. It's quite possible that someone has dissasembled it and rotated the top section (part 9 below) 180 degrees on assembly. If this is the case you can either pull it apart and make it right or just move the leads on the cap and pretend it didn't happen, this won't affect the engine at all.

I think Roger has sorted it out. It looks nice and clean inside the Distributor and when enlarged it looks like the screws on the sides have been removed. You said it came off an engine that didn't work. I would say someone disassembled the distributor and just reassembled it with the Rotor shaft assembly facing the wrong way. Either pull it apart to reassemble correctly or change the leads to suit if you want it running quickly.
Good call Roger.

taken it apart and yes, that's the answer . the shaft is split in the middle just like the picture.
however, with this car, one link leads to another
looks like the springs are different, so someone has replaced one or the other. i'm sure there's precise science involved here, but no one seems to sells the precise items
unless someone has a better idea, off to bunings tomorrow to have a look at something that looks similar

unless you know where to get set of brand spanking new springs, this is the only plan i have. no point getting used ones as they're likely to be buggered on a 45 year old car ( as one of these is). there are a couple of photos on the net, so i'll have just have to apporximate the thickness of the wire and the length

check this out! are they meant to be different?
that doesn' t make any sense, but it came from a reliable site
see the long hook? the weight just slides until it its the spring and its very stiff compared to the other side !
Posted 06 April 2017 - 09:10 PM
HOWEVER i dont have the circular hook - they're the same on both side, but some has defintely has messed with this becuase the tangs have been slightly bent. from what this article, it seems to behave correctly eg one hold the weight tight, and the other lets it flop out
some sort of a bloody analogue computer ?

To get it right you first need to know what advance graph you want and then choose the right springs to get there (and have a dizzy dyno to measure the result).
Or you could do what most of us do and chuck in whatever you have but I think you can still buy the stock springs from Nissan.
