This is a pulsar dizzy ?
I`ve spent all weekend disassembling & reassembling lots of pulsar dizzys (lost count!) & didn`t come across the one pictured! All of them were the bushed type dizzys. All the pulsars were 83-86 model N12`s. Is this the correct model that a lot of threads & the tech- articles describe? If so what`s it out of ? I`m sure a lot of other members would like to know also.
I also noticed that this photo has just recently been added to the photo album.
Any particular reason it wasn`t added previously? I would think that you being an experienced auto-sparky and also a member of Datsun 1200 you could have shared this knowledge with everyone earlier. Or is it a case of "look what I know", or just a case of not wanting to share information until coersed( spelling ).

The subaru dizzy didn`t have a thrust washer between the dizzy boss & the drive gear , it had about 1mm clearance ! So it DOES rely on the press fit between bearing & shaft to hold it in place ! Your theory on expansion affecting the perfomance is flawed the expansion rates of the bearing & dizzy shaft are very similar, and being in close proximity ( ie: next to each other ) has a rapid heat transfer, thus retaining its interferance fit ! If a 10 Ton press is needed to assemble & disassemble this bearing, Don`t 'FOOL' yourself into thinking it will fall off.
But what would I know? I`m JUST a fitter-machinist

Ha I gotta laugh, nah you busted me, its really a subaru dizzy. NOT
If you took your time and went back and actually read all the threads on dizzies in this site you would see that numerous times I have talked about the pulsar dizzy, just like numerous other members. The pic you are refereing to as being new is exactly that. Why would anyone wish to see inside a dismantled dizzy? (Wow mad its got a bearing instead of a bush, man thats gotta make the car go faster, better, and smoother.) Also the other pic of the modified bracket if you bothered to look, from memory ddgonzal has previously put up a similar pic showing the same basic thing. Why would I need to put up my pics if someone else already has?
As to which pulsar you could be onto something here, my dizzy is from a japanese importer and came off an E15 pulsar engine, quite possibly the australian models had various types of dizzies just like the 1200's did. I cant scan a pic of the part number on my dizzy as it wont show up, but here are the exact numbers on the side of the dizzy;
T4T84092 (8208 in little numbers)
Below that is a nissan symbol then in small numbers 22100 (75A10 in big numbers)
Maybe a member can locate this in their parts catalogue and give you all the info you require.

I dont really care but you stated earlier that the subaru dizzy was the optimum choice, so why would you spend all weekend dissassembling pulsar dizzies? Do you care to share where all these dizzies are? as they are a wanted item and I am sure many members would like to know their whereabouts.

Your theory of rapid heat transfer has a bit of merit but I would like to know of any mechanical part that has a bearing which is located and held in place by a bracket but yet the shaft is only a press fit. Bearings do create heat too you know. Subaru dizzies dont count for an example and dont try and say an axle bearing either as these are still held on by a retaining collar which is non moving on the shaft so heat transfer is the same as the shaft.

Its nice that your a fitter- machinest, so you personally should be good enough to make the 1mm clearance exact. Then why would there be any question of it not being 1mm but being more. If your happy with your decisions in whatever you do I am happy for you, if it takes a 10tonne press to put the bearing on I am sure heat wont affect it and the shaft 1 tinny bit. But if you belive it takes a 10tonne press to put the bearing on thats another story.

Anyway I am bored, Steve

WHY DOES NOBODY EVER NOTICE WHEN I SAY I CAN GET FACTORY ELECTRONIC DIZZIES!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

i CAN ALSO GET BLUEY SERIES TWO ELEC DIZZIES THAT ARE MODIFIED TO FIT A-SERIES

I HAVE ALSO SEEN A-SERIES WITH E-SERIES HEADS ON EM. i.e. OHC and X-flow


breath in breath out, ahhh, just venting my desire for attention

1200rallycar I always notice.

Glad you could share that helpful info with us all. Maybe I should change my name to Phunkwhatthafuckisrogueonabout?

how much?

Quote:Ah, that's a good one. The vehicle? Datsun B310. The stock Datsun 1200 distributors, starters and alternators were made either by Hitachi or Mitsubishi. Ditto for the B310 distributors.

Remember, keep your 1200 "all Datsun, all the time".

I'd like to know how much too cause if the price is right....

Can anyone please help me with my distributor swap. I got a 1200 ute and is the only one existing in my country(Sri Lanka) What I need to know is, are there any nissan latter model came with electronic distributors which can be directly swapped with my standard A12 distributor without any modifications needed?
