3 parts wheels glued
Hello,
i started dissasembling some PLS 3 parts 13 inch to respray the centers and repolished the aluminium.
Bolts came out easily ( only one broke)
Problem, they have been glued 
I can't even take the center part out.
What's the best solution ?
Warming ?
Apply force ?
they are quite old and the alloy is thin
Please help !

Depends what they've been glued with. Heat (enough to degrade epoxy or silicone based glues) may affect your alloy temper.

I would use heat. Most epoxies will let go at 200 degrees C or less. Most aluminium tempering is well over that. .... what could possibly go wrong....

300C is the lowest annealing temp for Al alloys. You that sure of your heating....?

Are you sure it's glue?
Normal practice is to use a smear of silicone to seal between the sections (which is obviously sticks them together, too).
You might try carefully running an old-fashioned razor blade or a fine, sharp scalpel blade between the sections, to see if that separates them.
Edited to add:
If it is silicone sealant, obviously heat won't work... you'd end up with a puddle of molten alloy and a nice, if slightly fragile,
circular gasket of silicone left behind.

As above.
I had Gotti 3 piece 73a split rims and the only way to get the slicks on were to take the wheel apart. I used silicone to help seal each piece and
ensure they were air tight when re installing. They will part with a bit of effort and gentle prying .

Finally have them done.
WD40 all night + razor blade
Thanks for your help
