Gearbox pressure plate removal

Hi folks
I'm probably going to make myself look a complete numpty but how do you get the pressure plate off the gearbox (manual box codes are 911/01 7 70 1992).
Worried about damaging anything by levering on the casing so i thought i'd ask the experts as i can't seem to figure it out... any pointers would be greatly appreciated.
For reference the Clutch fork still attached and the plate slides in & out ok
Cheers in advance

In my ignorance what do you mean by gearbox pressure plate?

I think he means the sportomatic version of the box, I'm curious too!

I’m guessing, since you have the “pull” clutch 911 gearbox, you have split the engine/ gearbox and are left with the clutch pressure plate being locked onto the gearbox.

I believe this is removed by rotating the release bearing so the clutch plate is no longer held by the lugs.

Me again, what's a pull clutch?

Release bearing pulls the pressure plate towards the gearbox to disengage (& change gear), instead of pushing the pressure plate towards the engine to disengage.

The main difference between the early 901 gearbox and the next version (the 911/) which was replaced by the 915

tks, I've seen/worked on the later 901 (as well as the 915 and G50), but not seen the earlier one in action.
