Rebuilding 68 E type 4.2l engine and managed to get the crank damper off with a pulle r. But struggling to remove the split cone . Tried sharp rap as Jag manual suggests without luck. Looked up earlier forum suggestions such as to pry from back of cone; no success and afraid of damage of using more force. Can’t get pulled behind it as one person suggested. Have used lots of penetrating oil before these tries.
I had a little trouble when removing mine so I put a screwdriver in the slot and slightly expanded the cone. Great care must be taken to not over expand it as it will split easily.
