Is its safe to remove the old Camshaft Gear from Suby EA81 heating it using a Oxy/Acetylene  torch, or is there another way,

These Camshaft Gears on the EA81 are fitted using heat and they are cast metal and break up under undue force. Ive got to

replace mine.

I was told you’ve got to split the cases. I didn’t want to hear that too if that helps. 
 

Good luck. Post back how it got done please. 

A "more gentle" option may be an induction heater. If you don't have one yet, I'd recommend saving up for a decent Chinese one ($200 range), they work wonders.

That way you're only heating up what you need to and you're not affecting the temper of the steel as much. I've never removed an EA81 cam gear, just my 2¢. 

Any machine shop worth their salt would tackle that no problem.

:]

Please investigate before you decimate.

If it’s in the block. Heat and pullers won’t do anything. 

Sorry I read crank instead of cam. 
Cam gear on the EA71 is two small bolts. Same on EA81
