Dizzy gear pin - Peter Arnold - 25-05-2021
Can anyone tell me if the pin securing the gear to the spindle of a DK-4A distributor is straight or tapered?

Hi Peter
I’ve used a straight pin peened over at each end. I don’t think (Hope
) that the hole is tapered.Cheers

Hi Peter
I think it's plain 1/8 th inch. See Lucas picture.

Use an 1/8" rollpin some replacement gears have a 4mm hole for Bosch distributors, a rollpin is a more secure fixing. Terry.

I agree a rollpin is the way forward

I agree, use a suitable rollpin.

Ha! No one sells Imperial roll pins in Townsville except a large engineering supply company but I really do not want to buy a roll pin kit with 1,200 variously sized pins. Looks like it will have to be a piece of 1/8" mild steel (welding rod?) riveted. Thank you for your replies.

Peter, not sure I should raise my head up over the parapet here but.......
Same situation, I need to change the bottom disty shaft, the one with the helical gears on my DJ4A.
Lucas says use a 1/8 “ pin. I did not have one and the UK is a couple of weeks away from me in NZ.
So I rustled about in my nail collection and found a galvanised nail slightly over size but a bit of coarse emery cloth reduced it to fit.
Firm fit and then peen or centre punch each end.
I did find that the hole going through the disty part didn’t line up with the hole in the new bottom shaft.
Turned it around 180 and all was good.
Not a lot of precision accuracy back in the day.
Cheers
Gary

Probably individually fitted as the picture."Handcrafted" or individually hand fitted and still much revered in some circles.
