Hi
Ozziesim,Yes mate, a 3 leg puller that fits the circumference of the large sprocket will do the job. Rolla has set you on path to success though, a little penetrating oil first left overnight and then the gear puller will do the trick and not damage any of the components.
Would you please be good enough to post some pics as you go along with your restoration, it will be great for the
ODK archives and maybe help other members in the future.
