Yeah its not budging, tried getting the engine hot and trying and no dice. I did get a good deal on a Cosworth gear and just sent that off to be refurbed.

The heat needed, sorry I was not specific, would be from a torch. Engine heat will not do the trick. I hope your cossie box works for you.

Indeed you need copious amounts of localized heat from a torch. To pull the pitman arm you also need crazy heat and a big ass puller.
