Howard Rotavator slip clutch

[Deere342]

Hi, what is the best solution here? The studs are rather rusty and the plate does not want to move much. Do I continue hitting it with a hammer? Don't want to damage anything in the gearbox. Or something to prize between the two outer plates?

Keep tapping the clutch flange around the bolt holes, it will eventually break the rust off.

As above and if you could make a can to fit around the shaft, fill with diesel leave to soak in
Keep turning the shaft or at least paint it on the top half

A bolt of the correct length for the gap, with a nut.
Run the nut out and tighten against the flange, but only to keep pressure on as you keep tapping.
Don't break the bit out .............
