AAN automatic crankshaft tailpiece removal tips?

[Jeffgordon]

Today when I got my new flywheel it find out that AAN from automatic have some kind of tailpiece at the back of the crankshaft, and manual doesn´t seems to have one. Any advise how I can remove that from the crank, seemed to be quite stiff?

Are you sure it comes off? Looks like it's part of the crank to me, in which case you'd have to machine it off.

They seems to be different material, and there is a little step where the tailpiece changes to crank, so I assume it can be removed. And I can´t see any idea why factory will make different cranksafts to automatic and manual..

yes it comes off,**** of a job.be patient and slit it across NESW and chisel it out

Can't help too much but this diagram shows the Item 18 AAN automatic transmission adapter "bushing" as something that is not bolted to the crank per se so is it is likely just press fit.

Nothing to see here. These are not the droids you are looking for.

Thanks for the help mates, I will try to beat that ******* when I'm next time at garage

Easiest thing to do is grab a 24mm drill bit and drill down the middle. It will drop straight of and then you pick out the remainder that's left over. Much easier than trying to pull/force/chisel it of.
