GTV6 Distributor Dismantling

[Fylnn]

I am trying to dismantle the distributor on my '83 GTV6.  It has a Haltech on it now and if I lock the distributor in place the advance can be controlled by the computer.  I want to do this before I get it finally dynoed.

I have it down to the point where the whole internals wants to lift out on the main shaft that goes down to the drive cog.  What I am unsure of is how to remove the lugs assembly off the bottom of the main shaft?  By that I mean remove the collar with the 2 lugs on it that drives the shaft up through the centre of the distributor.  It looks like it is held in place with a pin of some description.  it is not a roll pin but looks to be solid.  I almost looks like a grub screw except it has not hex I can see.  I have given it a few taps to see if it moves and it hasn't so far. 

So before I get right into this pin with a bigger hammer, has anyone done it before, and is there a trick other than a bigger hammer?

Got a piccy of the offending bit?

As you suspect it is a simple pin. No threads or such like. It's probably just lightly seized and needs some convincing or some sort of loosening agent.

Thanks for the assistance, I will try to get a photo and apply some WD40 before mounting a more convincing argument for it to come out.

how do you imbed a photo on these forums.  Never made it stick.

here is a photo of the drive dog.  Trying to get the pin out of the centre.  It is not hollow so not a roll pin.

The pin is an interferrance fit. Secure well in a vice using soft jaws as to not damage anything. Use a suitable pin punch. A few blows will drive it out. Note the off set of the teeth.

Suitable persuasion it is then, thanks for all the information.  I am glad verious people pointed out that it is offset, I had not noticed but will now look for it.
