Ford Other 1957

Help Help
I have a problem with the Distributer in the Ford 103e engine and i have to remove it.
Loosing the clamp can rotate the housing and tried to lift out the unit. it will not come up
Sprayed WD40 down the shaft drive . 24 hours later tried again no go .
Looke like the shaft is seized on the sloted Drive it shares with the oil Pump.
Fitted a small sling around the housing tried to lift it up with a small forklift . Also tapped the housing with the hammer to shock it . No Luck.
I was hoping not to remove the engine strip out to remove the oil pump .
I was woundering it anyone had this problem before.
I would appricate any help.
Thanks Noel Keohane Cork
